I recently had to build a new array due to an HDD failure on my old one (after 7 years of continous use), and jumped on the deal on Newegg for the Ultrastar DC HC530 14 TB.
It is currently set up in RAID 0 volume using the mobo controller (ASUS ROG Maximus IX Hero Z270) using 3 of the Ultrastars, connected using the dongles provided by goHardDrive to override the power reset pin issue, on a Windows 10 machine. CrystalDiskInfo had shown no issues with the drives.
Right now, it appears to be deleting some of the newest files I put on the volume; I cannot determine how it chooses to erase/delete the files I put on, but it only seems to affect the newest files that are put on the volume. Filetypes lost include .jpg, .mkv, .mp3, and .flac, so no real pattern there. I should be extremely far from the overall capacity of the volume (sitting at around 14 TB used). Files that are being seeded that are deleted do not appear to be missing in the latest release of qBittorrent (v4.6.5) until I force a re-check, upon which it detects the files to be missing, though I will stress that there are files that are not being seeded that also disappear, so I don't believe that it is something related to qBittorrent.
Nothing obvious jumps out at me on the Windows Event Viewer. I get a large number of errors stating "Metadata staging failed, result=0x80070490 for container ____________", but my Googling seems to tie that to some other issue primarily on Microsoft's side.
I have tried rebooting the computer. I'm not losing much data due to the fact that I have BackBlaze and a second local back-up array (second computer on the LAN running RoboCopy every night, have been doing it for years and its never deleted anything via RoboCopy), but it is very, very annoying to have to keep doing recoveries, only to have many of the same files get deleted overnight again.
I do run an FTP server off the drive using Filezilla, but I don't believe I've given anyone but my own account the ability to delete files.
What else can I do to troubleshoot the issue? I'm considering wiping the volume and setting it up a JBOD instead just to see what happens, but then what do I do if that also fails?
