February 1, 20224 yr Hello, I have ran in to a bit of a problem to say the least. I have a unraid server with just a boot ssd and a 2tb hdd for storage, its not protected or anything. I rarely use it and i put some backup stuff on there. After a month i scanned it and went to bed and woke up to 480 milion errors. Windows is not showing any files and krusader isn't showing any files in my storage folder. But unraid tells me in using 301GB of space on the drive? does this mean not everything is gone or am i too late If u can help me it would be greatly appricated. Friendly regarts, Ruski
February 1, 20224 yr You need to post your diagnostics. Also, the # of errors refers to the number of sectors, not any "used" space per se
February 1, 20224 yr Author Here is the diagnostics. I am pretty new to all of this so if u need anything els just tell me and ill try to get hands on the information imkonas-diagnostics-20220202-0041.zip

February 1, 20224 yr The data drive dropped offline, then reconnected itself. Reseat the cabling both ends to it. How is it connected?
February 1, 20224 yr Community Expert Looks like disk1 disconnected and reconnected as a different device. How is that disk connected?

February 3, 20224 yr Author Okey i tried reconnecting the cables. Now it shows more files in my explorer. But i cant open them becuase its says its damaged. I did a new diagnostics (Added) what can i try next? imkonas-diagnostics-20220203-2310.zip
February 4, 20224 yr Author I think i fixed it. (ill mark it as Solution when the check is ready but its taking a while) I stopped the array. Unassigned the drive. Reassigned the drive. Started the array. So far 50% no errors

Your first post implied you didn't have parity, so there is no way you can rebuild anything, which is what those steps you posted are designed to do. Post new diagnostics and a screenshot of Main - Array Devices

Post new diagnostics and a screenshot of Main - Array Devices The scan is complete and it has 0 errors now. and all the files are back. What i did was shutdown the system, Reconnect the cables, Turn system back on. Then i ran a check it still had 488 milion errors. Then in main i stopped the array. The devices list popped up i deselected WDC 2TB and scrolled down it said i cant start it cuz missing drive (makes sense) then on disk 1 i just reselected WDC 2TB. Started the array and checked 0 errors and the files now work So i dont know how it fixed it but it did. diagnostics are in attachments imkonas-diagnostics-20220204-0920.zip

February 5, 20224 yr Author Okey, i reconnected the 2TB drive because it was in a 2.5 to 3.5 cage so it mabye that was a problem. I looked in the BIOS i could turn off the raid but then it would have been switched to IDE mode. So i attached my diagnostics. Is this better? is the connection problem still there? the check came out with 0 errors imkonas-diagnostics-20220205-2316.zip
