Hello everyone, I'm a bit new to true data hoarding and I had made what is probably considered rookie mistakes.
Some backstory: I had an unfortunate ssd failure which cost me about $1000 to recover the files. After some research I've decided to set up a NAS w/ RAID1 (and other back up methods). Now I have some questions to help me transition/transfer/migration from my old external hdd setup to my NAS solution.
My first question mainly revolves around keeping file integrity when transferring files. What programs are best at doing this? I've done some research and I've currently chosen TeraCopy. It looks pretty good; other posts have suggested stuff like Robocopy but I couldn't find/get it to work (maybe it's command line stuff that, though I admittedly didn't look too hard since I don't trust inbuilt windows stuff that much). How good is TeraCopy and its file integrity verification?
My second question is about checking files for corruption, mainly videos. This one is a bit of a shot in the dark, a hail mary hope of mine that I can fix this headache inducing rookie mistake of mine. Long story short, I had to reinitialize my NAS due to changing its setup. When doing this, I copied data I had on the NAS to a ext HDD (no verification done, I now know it was a stupid rookie mistake) totaling approx 3.5 TB of data, mainly video files (probably around 1k hours). Now I found at least 1 of them has a bit of corruption, where about 20 seconds got messed up. Is there a way or program that can find these kind of problems with files? I'm guessing probably not, but if there are potential solutions I'd love to find them. Otherwise, I guess those errors/problems will just exist and years later I'll find out and lament that if I knew years ago I could have replaced those files but not when I do.
Thanks for your help and I'll reply if I have any follow up questions.
