January 2, 20179 yr I accident delete my harddrive data by selecting wrong drive in array setting,how can i recover it?
January 2, 20179 yr Community Expert Please explain more thoroughly what exactly you did. Are you saying that you assigned a data drive to the parity slot, or are you trying to say something else entirely.

January 2, 20179 yr Community Expert I select the wrong hard drive for hard drive 1 in the array,my files is gone on that drive Still unclear. Drive1 is a data drive and if you assign a disk to drive1 that shouldn't affect the files on that disk unless you somehow managed to format it or unless you went through a lot of trouble to make unRAID think it was a new addition to an already valid parity array. Instead of drive1 do you actually mean the parity drive like I said before? Parity is drive0.
January 2, 20179 yr Community Expert I still don't understand what you mean. Are you saying you don't have a parity drive, but you accidentally assigned one of your data drives to the parity slot? If this is indeed what you have done then it is very unlikely that you can recover any files from it. Do you have backups?
January 2, 20179 yr Community Expert OK. You don't have a parity drive. You assigned a disk to some slot. Was this a data disk that you had already been using in unRAID? Or was it a disk from some other system? Did you actually assign the disk to the disk 1 slot, or did you assign the disk to the parity slot? If you assigned the disk to the disk 1 slot, and it was a disk that unRAID already had data on, then there should be no problem with the files on the disk. Go to Tools - Diagnostics and post your complete diagnostics zip file. Also post a screenshot.
January 2, 20179 yr Community Expert You aren't answering any of my questions. What is your native language?

January 2, 20179 yr Community Expert OK looks like you have assigned disks to 1,2,3. Why do you think you have deleted the data? What filesystem do you think was on the drives? What operating system put data on them?
January 2, 20179 yr Author Why do you think you have deleted the data?because the disk didn't show in This PC What filesystem do you think was on the drives?NTFS,exfat,fat32,hfs+ What operating system put data on them?Windows and macOS
January 2, 20179 yr Community Expert From your syslog, it doesn't look like unRAID actually tried to mount any of the drives. If it is telling you they are unmountable or unformatted that is just because the filesystem on the drives is not a filesystem that is supported by unRAID for array drives. You must let unRAID format any disks it will use in the array. If you have data on these disks then you will have to use some other disks in unRAID to get started and then you can copy the data from these disks.
January 2, 20179 yr Community Expert f the disk is from another system then assigning it and starting the array will cause the partition table to be rewritten to what unRAID expects. As long as you have NOT told unRAID to format the disk then the data is probably recoverable using the appropriate tools. The tools to use will vary according to how the disk was previously partitioned and what file system(s) you were using.
