Have a very important 12tb hard drive with about 6td of data on it. went to plug in and shows 12TB unknown in disks. Tried testdisk and the log shows infinite I/O errors like this:
Disk /dev/sda - 12 TB / 10 TiB - CHS 1458933 255 63
file_pread(4,1,buffer,34(0/0/35)) read err: Input/output error
file_pread(4,1,buffer,35(0/0/36)) read err: Input/output error
file_pread(4,14,buffer,36(0/0/37)) read err: Input/output error
file_pread(4,3,buffer,50(0/0/51)) read err: Input/output error
file_pread(4,3,buffer,97(0/1/35)) read err: Input/output error
file_pread(4,8,buffer,113(0/1/51)) read err: Input/output error
the smart log is printed below. Please Help Thanks!
