Hello all. Looking for some advice -

I recently built a new nas pc and migrated my zfs pool hoping it was as easy as importing it in the new install of truenas on the new pc.

I bought an LSI 9207-8i P20 hba that is attached to a PCIe lane and it shows up in truenas using lspci so its being detected . The seller said it was flashed to it mode but i havent been able to confirm yet. From the same seller i also bought a mini-sas to sff 8482 splitter that i use to connect my disks. Sata power is supplied to the back of the connector via the psu.

In my previous build (Dell precision tower) the disks would show up and work but now,the disks are cold/silent. Theres no server parts per se in my new build, just consumer parts. Ive heard it can be the 3.3v power coming from one of the pins on sata connectors that can make disks not want to start. The disks are all wd/hgst ultrastar dc330 10tb drives. Ill get around to checking the model number when i get home to see if it might be that.. any other suggestions or am i out of luck ? Appreciate any advice

I haven't built a computer in years so I'm out of touch with what's new.

I currently have a 12 bay synonyms nas that I bought in 2017 with 12 10tb drives. It's almost full and while I like turn key reliable things, the price tag of the latest 12 bay synology can go throw itself off a cliff.

I'd like ten or more 20/24 tb drives. It will be a media server and run plex and my docker media stack. Will need at least one 10gb network adapter

Will probably go with unraid unless someone convinces me otherwise. It seems stable enough.

What's your dream build?

This drive is now exuberantly expensive, and amazon will not ship it to my country anymore either so if it went on sale I cannot get it. It's never on sale in my country. I like it due to its noise level and speed, plus its WD for added longevity. Any recommendations? It will be used in an array as I don't use the content that much and not willing to cash out for a NAS to start with. No enterprise edition, it's just too noisy

Hello Data Hoarders,

I've come to you today seeking your expertise in finding a new backup drive to purchase. It's been quite a while since I've researched storage, and the more I learn, the more questions pop into my head so I figured it would be best to lay it all out here.

So starting off, my main reason for getting a new drive is that I need space for my locally recorded Twitch streams and edited YouTube videos. These are usually 10-20+ Gigabyte files, so I'm looking for a drive that both has a lot of space, while being able to transfer bigger files in a timely manner. Previously I assumed an HDD would be the best option due to the price/storage ratio on SSDs, and currently I'm using a WD Black D10 external HDD to do this, but am about to run out of space, and WD/Canada Computers don't have these in stock.

After searching the Canada Computers website, I noticed there are quite a few different options when it comes to HDDs/SDDs and was wondering the following:

1. For a Desktop PC not being used in RAID, does it really matter if the HDD is SMR vs CMR? I see the 8 TB SeaGate Barracudas are a decent price, but looked them up to find they are SMR drives, which people often advise to avoid. For my case would it really matter considering I intend to use the drive as a more long-term storage and won't actively be gaming or constantly reading/writing tons of stuff to it?
2. Are there any negatives for using a NAS drive in a PC? I've been told these drives are great for servers since they are made to run 24/7 and are more durable. I run my PC 24/7 so thought perhaps they would last me longer in terms of drive health?
3. I've seen a couple posts of people stating in comments to avoid buying external HDDs because they are often 2nd or 3rd tier drives (I don't actually know what they mean by this) and that it's better to buy an on-brand desktop HDD and put it in an enclosure yourself... is there any merit to this claim?
4. Are there any real differences between using an internal vs an external HDD? From my understanding aren't most external HDDs just a regular HDD in an enclosure? I kind of like the idea of having an external that can be totally disconnected when not needed, and easily able to bring to a different Pc if I need to share files.

In case it helps, my current setup is a 500 GB Samsung 860 EVO NVMe M.2 (OS Drive), 1 TB Seagate Barracuda HDD (st1000DM003-1CH162 - Swear this thing is like 10+ years old), 1 TB WD Black SN750 NVMe M.2, and my WD Black D10 8TB external.

Thank you so much!

Edit: Since posting I've learned about Shucking Drives. It appears the drive inside of the WD D10 is a Ultrastar DC HC320 that retails for $350 CAD, pretty good since I got the D10 for around $200 - $250 a few years ago.

Comparing the SeaGate Barracuda 8 TB I saw at $189 to another WD D10 8 TB for $250, would it be worth the extra money? The SeaGate is an SMR, while the WD is a CMR.

I can only find 24 bays , but nothing with the extra two 5.25

I'm wondering if there is some consensus on which codec formats to choose with archiving youtube videos?

We at equal bit rates AV1>VP9>h264 for video and Opus>AAC for audio but youtube seems to go with much lower bitrates for the more advanced codecs.

Although it seems like youtube pairs AV1 with 96bit AAC.

This will be a long post, I hope people can share some ideas and help me with my data. I am an accountant and tax preparer. On personal side, I have music, movies and online gaming hobies. I recently started photgraphy and now maintain around 4 tbs of videos and pictures which are also growing day by day.

During my day, I use different computers. I have a desktop PC at office and a personal macboon pro which I use during the office, portable for meetings and use it for casual adobe lightroom/movies/browsing etc. The macbook also has windows installed, where i use office, excel, outlook classic etc. as i am more comfortable with it on windows. During the office, we also have our main tax softwares installed on a server, which i can access using remote desktop.

For office email, I use outlook which is configured on office desktop, at the server, on macbook, on macbook parallels partition, and also on the alienware. For my office workflow, I heavily rely on my emails. I also create diffeent spreadsheets, powerpoints slides and word files. Most of the tax returns prepared and bookkeeping stiff is on the office server.

I also have a gaming laptop, an Alienware which I use to mostly play games. It also stores my personal data. At home, the alienware and macbook pro connect to a untrawid monitor. I also have a synology NAS that stores the movies, personal data and photography stuff. All in all, this makes about 6 different systems i work with (excluding a NUC that just run plex). **1)**office desktop, 2) office server 3) macbook pro MacOS 4) windows on macbook pro MacOS 5) alienware laptop 6) synology NAS

My first problem is how to sync my office data between my different systems. I work from home sometimes too. At home, I need to work on alienware for office. Sometimes during office, using desktop is the better option(as it has 3 screens) and sometimes when i am meeting clients, or in another office, i use the macbook. Whichever system I am working at, ome working papers are stored there locally. Most of the time, since I am using emails, i just email the data. If client calls, or i have meetings with colleague or offshore ops, I need the data on the system i m working at. Storing everything on the synology drive makes it harder to access from office environment, as for some reason, upload speeds are too slow when accessing the network from outside my home.

I tried using icloud services, did not work as smoothly as I wanted. I tried using synology drive, it works to some extent but the upload speed from home is too slow. Managing data between different systems is becoming a nightmare. I tried using the office server to main all my files there, but the biggest problem is, it cannot run an outlook smoothly. Its not fast enough.

Secondly problem I am seeing is how to manage the photos uing lightroom, with th flexibility to use either the alienware or the macbook to view and edit files. I want to use lightroom classic, not the cloud version as it will quickly get too expensive to maintain.

Any ideas on how people have managed similar situations. I know ideally i should restrict my workflow to maybe the office desktop, office server and macbook. But ocassionally i need the alienware too when I am at home. Any ideas would be appreciated.

I occasionally see Seagate changing the price for its HDDs on the Amazon store. There have been at least 3 times last year when the 12 TB version has gone down by $50 at least ($339 -> $275)

https://a.co/d/gBLmTIT

Anybody knows (who has been tracking the prices) when they’ll be doing it next probably?

Hey everyone,

I'm in a challenging situation with a corrupted-21.4GB\multiple MP4 video file(s), and this is actually a recurring problem for me. I could really use some advice on both recovering this file and preventing this issue in the future. Here's the situation:

• The Incident: My camera (Sony a7 III) unexpectedly shut down due to battery drain while recording a video. It had been recording for approximately 20-30 minutes.
• File Details:
  • The resulting MP4 file is 21.4 GB in size, as reported by Windows.
  • A healthy file from the same camera, same settings, and a similar duration (30 minutes) is also around 20 GB.
  • When I open the corrupted file in a hex editor, approximately the first quarter contains data. But after that it's a long sequence of zeros.
  • Compression Test: I tried compressing the 21.4 GB file. The resulting compressed file is only 1.45 GB. I have another corrupted file from a separate incident (also a Sony a7 III battery failure) that is 18.1 GB. When compressed, it shrinks down to 12.7 GB.
• MP4 Structure:
  • Using a tool to inspect the MP4 boxes, I've found that the corrupted file is missing the moov atom (movie header). it has it but not all of it or maybe corrupted?
  • It has an ftyp (file type) box, a uuid (user-defined metadata) box, and an mdat (media data) box. The mdat box is partially present.
  • The corrupted file has eight occurrences of the text "moov" scattered throughout, whereas a healthy file from the same camera has many more(130). These are likely incomplete attempts by the camera to write the moov atom before it died.
• What I've Tried (Extensive List):
  • I've tried numerous video repair tools, including specialized ones, but none have been able to fix the file or even recognize it.
  • I can likely extract the first portion using a hex editor and FFmpeg.
  • untrunc*:** This tool specifically designed for repairing truncated MP4/MOV files, recovered only about 1.2 minutes after a long processing time.
  • Important Note: I've recovered another similar corrupted file using untrunc in the past, but that file exhibited some stuttering in editing software.
  • FFmpeg Attempt: I tried using ffmpeg to repair the corrupted file by referencing the healthy file. The command appeared to succeed and created a new file, but the new file was simply an exact copy of the healthy reference file, not a repaired version of the corrupted file. Here's the commands I used:

      ffmpeg -i "corrupted.mp4" -i "reference.mp4" -map 0 -map 1:a -c copy "output.mp4"

• A Common Problem: Through extensive research, I've discovered that this is a widespread issue. Many people have experienced similar problems with cameras unexpectedly dying during recording, resulting in corrupted video files. While some have found success with tools like untrunc, recover_mp4.exe, or others that I've mentioned, these tools have not been helpful in my particular case!?!
• Similar Case on GPAC/MP4Box Forum: a relevant thread on the SourceForge GPAC/MP4Box forum where someone had a similar issue: https://sourceforge.net/p/gpac/discussion/287547/thread/20466c3e/.
• Tools that don't recognize the file include:
• Recover-mp4
• Shutter Encoder
• Handbrake
• VLC
• GPAC When I try to open the corrupted file in GPAC, it reports "Bitstream not compliant."
• My MP4Box GUI
• YAMB When I try to open the corrupted file in YAMB, it reports "IsoMedia File is truncated."
• Many other common video repair tools.

Is there any possibility of recovering more than just the first portion of this particular 21.4 GB video? While a significant amount of data appears to be missing, could those fragmented "moov" occurrences be used to somehow reconstruct a partial moov atom, at least enough to make more of the mdat data (even if incomplete) accessible?

Any insights into advanced MP4 repair techniques, particularly regarding moov reconstruction?

Hi everyone! Long time lurker first time poster 😅

I've been paying attention to this community for a while now and I've now have my personal data properly stored and backed up. I now want to move onto storing a lot more data (movies, pictures, books etc) so I'll need a better setup than what I have right now.

My current option is a DS1522+ with 5 20TB WD Red drives. This can then be expanded into a 15 array using two DX517.

Thing is, I already have this 15 array goal in mind, and since I want to build a PC for personal use and have a homelab on a secondary machine while speaking with a colleague he suggested that I might be better served using a server rack to keep things more organized and tidy.

While the concept looks really attractive I've been having some trouble finding the parts I might need to build this.

First and foremost having my plan in mind would you go with the pre-built nas and eventually move to the server rack, go straight to the rack or don't use the rack at all?

And in case you would advise for the rack is there any site where I can find a hardware list to compare what I would want/need or for this kind of hardware I better served going directly to the manufacturer page?

Thanks in advance, and if this isn't the best sub for this question could you please point the way to one that might be better?

I’ve been trying to configure OrpheusDL to rip high-quality audio from SoundCloud, but I’m running into issues and could use some help. My goal is to streamline the process of downloading tracks from SoundCloud using command-line tools like OrpheusDL.

I’ve used other rippers, such as Lucida, which does a fantastic job of ripping HQ audio (256kbps or 320kbps when available) with all the metadata intact. However, I want to transition to a more streamlined and customizable solution like OrpheusDL for better control and efficiency.

Here’s what I need:

• I don’t want to download anything below 192kbps, and ideally, I’d like 320kbps when available.
• I need as much metadata as possible (artist, title, album art, etc.) since I use the files in Rekordbox for DJing.
• If possible, I’d love guidance on automating the process to extract and use SoundCloud API access tokens or any tricks to unlock higher-quality streams via OrpheusDL.

Does anyone have experience configuring OrpheusDL for SoundCloud? Are there any additional dependencies, configurations, or scripts I should know about to optimize the process for HQ downloads?

Any guidance or even alternative workflows/tools (as long as they are command-line friendly) would be greatly appreciated!

So I have been reading the DM for Archive by Pioneer combo(writer+bd-r) and I stumbled upon the testing results.

30°C + 80% RH is 100 years like they advertise in promotion materials.

However if we store in 25°C + 50% RH the longevity goes up to 6468 years. Yes is not a typo, 6468 years in a 95% lower confidence limit.

Here the results:

I have 2x 500GB Samsung Evo 970 Plus drives in one of my Unraid servers

One 12month old the other 6months.

Over the last week or so i started getting high temp warnings when it has been running its cache to array moves overnight - around 65C on one of the drives.

Was looking into it today and noticed that drive is running 10ºC warmer at idle when they were always previously similar temps

and Interestingly both drives have used 1 and 2% of spare threshold with 99/98% remaining endurance.

This seems odd to me for such new drives with under 30TB written each

To me that seems like they might be headed to early failures? thoughts?

In contrast i have a pair of 5+ year old Kingston A2000 1TB drives in another server that are over 500TB written with zero spare threshold used

I am running low on space. Currently debating between a 8 tb hdd ($150-$200) or a cheap external blu ray drive ($50) and 50 pack of blurays ($30). Going the bluray route will get me 12.5 tb for about $80. But is it worth all the trouble of burning discs? I sort of like the idea of having data stored I can essentially forget about and not consider deleting when I am in need of storage. But the convenience of a large hdd is hard to beat. Is bluray worth the trouble?

I am using an EVGA SuperNOVA 850 G2 to power 4x6TB SAS Drives (HUS726060AL5210 specifically) I cut out the orange wire/3.3v wire to disable the power-disable feature. My SAS controller is a Dell H200 and I have 8087 to 8482 ports but each of them seem to be working.

My SATA power cables are off-brand using 2 COMEAP Sata Power cables for my power supply, 6pin to 3 sata power. I had to use offbrand since the power supply was used before and I threw away the extra cables a few years ago when I built with it.

My issue is that I can power 3 SAS Drives no matter which combination of the 2 Sata Power cables that I got (e.g. 3 on line, or split 2 and 1 between the both of them), but as soon as I try to add a 4th it does not spinup. I've tested each drive and each breakout cable end individually and they all work, so I am suspecting a power issue. Possibly the 5v, but I am not entirely sure.

Does anyone know what could the issue? Let me know if I should include any more details to troubleshoot, thank you!

Hey everyone!

Looking for some advice! I had originally planned on going the route of buying a disk shelf and connecting it to a rackmount host machine but was scared away after being advised by a relatively well known youtuber that he would not advise disk shelves due to the many issues he and others have had with them in the past as it relates to the host machine not seeing the shelf after reboots. Now I assume the proper reboot procedure/order had been done and it was just some inherent issues of running two separate machines and the potential pitfalls that come along with that.

I'm new to the NAS space and I'm still learning, I currently use a asustor lockerstor 10 gen 3, but I want to move towards and build a unit using truenas/ZFS. I was looking at units on ebay, amazon, you name it. Some of the stuff on amazon had me concerned about backplane failures, cheap construction leading to hard drive destruction and what not. I've learned quite a bit the last month, HBAs seem simple enough but SAS cabling, different backplane configurations, certain backplane limitations or pitfalls are all things I don't want to overlook and get wrong. If I build my own 15 drive server with an amazon case, is direct wiring 15 drives even practical? or does it just leave a massive nest of wires leading to airflow/cooling issues?

My rack is in my basement, sound is not a concern, plenty of space left in the rack.

I guess I'm just wondering if you'd be willing to share what you're running and your experiences with it!

So, with HP tape and library tools, you get tape drive margins and tape head life remaining given in percentage, you'll see something along the lines of head life remaining 99% or so, if you're lucky anyway.

Is there a way of finding that for IBM LTO drives in their software? I've been trying to go through the logs but can't find anything, any ideas? Thanks.

I've been slowly building up my collection of mostly media archives spread onto several USB powered 2.5 external HDDs (almost all 5TB Seagate). Right now I'm in the process of re-organizing data and running a write-read surface checks on each drive to check their health status.

My idea is having each external HDD dedicated to a particular type of data, and it has worked well so far. Eventually, I had to divide some upon exceeding storage (e.g. movies and series, or games into eastern/western), but once it's all in one place and the drive has a sticker on it, it's easy to grasp what's where.

The choice fell on portable drives simply because I have not had a permanent place of living (still renting), so investing into a storage system and network was out of question. I also do not need them all connected/accessible at all times, so it's mostly for personal archiving purposes. Although I do want to share/seed what I have, which makes it hard with the current setup.

Also, what started as a couple drives is now 8 drives (and a few older smaller capacity ones, which mostly serve as duplicate backups for the least re-downloadable content). I've also just ordered another two after seeing a price increase and availability decrease, and that made question if I'm doing the right thing...

I understand that eventually I will have to split data I have on each further, and think of the proper backup solution. I wish 5TB wasn't the market limit for decades now, but also theoretically a single 5TB failure is not as painful as one 15TB+.

I've also had a couple externally powered desktop HDDs (alive since 2012), and while they can offer greater capacity, they are really inconvenient both in terms of bulkiness and extra power supply. I might get one large capacity in future (and if there's gonna be a great deal) just to duplicate data I want to share/seed 24/7 from my laptop.

With all that said, did anyone go through a similar phase and have any advice to share? I'm afraid I'm still not ready for NAS or RAID setup, but idk if that's inevitability, or if there any other solution? People with externals, how do you manage and keep track of your data? How do you store your externals?
