Hello ubuntu members...
I have since yesterday a problem with a Iomega Home Media Network Hard Drive (HMNHD) that used to work for over 2 years now. This resulted after a general power outage and i believe that this corrupted the hard drive OS resulting in having no more access to the files. There are critical files i need to restore (they were put on the drive last week and had not been "copied" yet to a second NAS because the saving cycle that runs every 2 weeks was due to run today (too late !!!)
I did several tests before coming here for help, as i think the Hard drive Seagate 1 To SATA) is not yet failing but Corrupted data is in cause... Here is where i got to : Running under windows several softs, gives me following information : - Disk is running GPT-EFI. - Ease Us : Sees 7000 files and can restore them, but several gz files are splitted (see below reasons) - TestDisk sees GPT-EFI Disk Type, and indicates :
Current partition structure: Partition Start End Size in sectors 1 P Linux Raid 65536 42008576 41943041 [primary] [md0] No FAT, NTFS, ext2, JFS, Reiser, cramfs or XFS marker 2 P MS Data 42008584 1953525106 1911516523 [primary] 2 P MS Data 42008584 1953525106 1911516523 [primary]
And after a quick analyse :
Disk /dev/sdc - 1000 GB / 931 GiB - CHS 121601 255 63 Partition Start End Size in sectors >P Linux LVM 65536 42008447 41942912 P Linux Raid 42008448 42008575 128 [md0] Linux Raid 42008584 42008591 8 [hmnhd-TID0YM:1] Linux LVM 42008584 1953524999 1911516416
As you can see there is a linux Raid Partition which could explain why ease us in not able to recover data (gz files splitted)... Testdisk was not able after 14 hours to recover data ans was still analysing disk.
I decided to switch to ubuntu live-cd and try to recover what i could (i have done this for other disks and this used to work well)
So here we go :
ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted.

Ok GPT Type.. lets go on with gdisk

I tried to mount /dev/sdc2 with several types and all i get is the following :
ubuntu@ubuntu:~$ sudo mount /dev/sdc2 /media/external/ mount: unknown filesystem type 'linux_raid_member' ubuntu@ubuntu:~$ sudo mount -t ext2 /dev/sdc2 /media/external/ mount: wrong fs type, bad option, bad superblock on /dev/sdc2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I need to access these files and recover them, what can i do now or how can i proceed...
Thanks by advance to support community for your advices...
