I recently unmounted a 4TB hard drive from one computer in order to access the files directly from another computer. It seemed like there were no problems with the unmounting process. When connecting the hard drive to the other computer, the hard drive is recognized in "/dev" as sdb, but the partition "sdb1" is not appearing, therefore I cannot mount it. If I run
fdisk -l /dev/sdb WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sdb: 4000.8 GB, 4000787030016 bytes 255 heads, 63 sectors/track, 486401 cylinders, total 7814037168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 4294967295 2147483647+ ee GPT
The sdb1 partition shows up. Since this is a 4TB partition, I also ran the command
parted /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: ASMT 2105 (scsi) Disk /dev/sdb: 4001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags
Then typed "print". In this case, the sdb1 partition does NOT show up.
Why is there a mismatch of information here? Does this mean that the partition has been deleted? Is there any way to possibly recover this partition and mount it?
Thank you very much in advance
