This all happened yesterday:
This drive is used entirely for games and all non-replaceable data is frequently backed up by Steam Cloud and such so thankfully I lost nothing. However I'd like to know whether I should just replace the drive (it was a prebuilt, would rather just pay for a new drive than send the whole system away for a month - keeping the original drive in case I have to RMA it for something else), whether it's an indication of some larger issue with my motherboard (my main issue is if my SSD could be corrupted, though I do regularly backup so this wouldn't be a total travesty), power supply or Windows installation, or whether I should just continue per normal unless things start to go awry again.
MBAM scan clear, doesn't seem like malware.
Sorry for the long post, opinions appreciated.
- In the morning, the DS4Windows icon on my taskbar had disappeared and it said the executable had been deleted. I thought Windows Defender may have gobbled it but this was not the case. Wasn't overly concerned, reinstalled it without much incident.
- I installed a Steam game and played it for a few hours, closed it, then came back to it to find it crashed to a strange error that I couldn't find anywhere. I tried verifying the installation but it kept complaining of "Corrupt Disk", and indeed a few folders in the game directory were corrupted and could not be opened. Had no luck reinstalling onto the hard drive, installed onto my SSD just fine.
- Tried opening Game 2, Steam complains missing executable, game has totally disappeared leaving just a .vdf file and alarm bells start ringing in my head.
- Check Game 3, huge portion of game files missing. Start to suspect issue with drive. A few games had disappeared altogether taking the whole folder with them. Game 4 also had substantial portions of their files missing.
- Massive disparity in amount of hard drive space available. Windows Explorer said 1.2TB were occupied right clicking on D: drive, but 800GB filled when I highlighted the entire contents of the drive. This seems about right for the number of files that disappeared.
- Ran chkdsk /f /r, about 11,000 orphaned files, some recovered but many of them didn't. chkdsk told me it moved the files it couldn't place in \found.000, this folder only had 4GB worth of stuff and was nowhere near as much as was still occupied. (should've been like, a hundred times that...) chkdsk flagged no bad sectors, just a bunch of corruptions and missing records. Game 1's folders were now fully accessible, many still disappeared.
- Ran sfc scannow and DISM, no issues with Windows.
- SMART indicators all nominal. Reallocation count zero. Shutdown and went to sleep.
- Woke up to find Game 4's folder was gone entirely, Game 3, which I had previously reinstalled shortly before the checkdisk scan was missing its executable. (though I didn't check whether it actually had successfully reinstalled after the chkdsk) Decided to do a full reformat of the drive since I couldn't get rid of the 400GB of space otherwise. Reformat concluded with no bad sectors flagged, full space available. I'm no expert with hard drives but if it was a file system issue, a reformat may have resolved it?
