When I direct attach the 4tb hard drive to my linux desktop. I see the following from parted.
Model: ATA WDC WD40EFRX-68W (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags
3 15.7MB 528MB 513MB primary msftdata
1 528MB 2576MB 2048MB ext3 primary raid
2 2576MB 4624MB 2048MB ext3 primary raid
5 4624MB 4724MB 99.6MB primary msftdata
6 4724MB 4824MB 101MB primary msftdata
7 4824MB 4826MB 1049kB primary msftdata
8 4826MB 4828MB 2097kB primary msftdata
4 4828MB 4001GB 3996GB primary msftdata
I see that partition number does not have a type of file system. Does it mean partition 4 is corrupted ? In earlier posting I saw that partition 4 has to be ext4. How can I recover this partition ? Its unfortunate that WD did not think making the recovery mechanism simpler.
