January 10, 20215 yr Hello, I screwed up some how and one of my SSDs I was using as unassigned device cannot be mounted anymore. I bought a new hard drive and when I installed it I somehow ended up screwing up one of my SSD that had data in it. When I brought my array backup the SSD appeared in unassigned devices like usual but it would not mount, the only option it gave me was to pre-clear it. I read that doing a pre -clear doesn't format, so I went ahead and did it. Now the device will not mount after the pre clear completed. I have followed the steps to try and recover the data but I keep getting the below error. Jan 9 19:15:28 Daisy unassigned.devices: Mount of '/dev/sdb1' failed. Error message: mount: /mnt/disks/SanDisk_SDSSDX240GG25_123273400239: unknown filesystem type 'precleared'. When I try to mount via terminal I get below error, even when trying to mount in read only to recover data. mount wrong fs type, bad option, bad superblock on /dev/loop4, missing codepage or helper program, or other error. syslog.txt Edited January 10, 20215 yr by bootlegspider a

January 10, 20215 yr Author Son of a b! That blows, good thing it wasn't anything too important. Now I know to stay away from preclear.
