Recover Data From Failing Harddrive

Hi, Using F12 with a LVM Volume,
Single disk with OS on and boot partition.

The OS HDD is getting i/o errors, but will still boot to the login screen.

i've removed the HDD and connected it to a Fedora Live OS on my laptop, connected the HDD and it registers as :

[root@localhost]# fdisk -l /dev/sdd

Disk /dev/sdd: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000e0069

Device Boot Start End Blocks Id System
/dev/sdd1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sdd2 26 30401 243991201 8e Linux LVM

and it tried to mount /dev/sdd2 to view and see if i can recover some files.

[root@localhost]# mount /dev/sdd2 /mnt -t ext4[root@localhost james]# mount /dev/sdd2 /mnt -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sdd2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Can anybody advise me of a way to mount the partition to allow me to try and get soem data back, or if trying to do a full backup of the drive you can get it to ignore i/o errors.

Any help would be appreciated.

Re: Recover Data From Failing Harddrive


It seems on /dev/sdd2 you have an LVM volume. You need to activate the volume group first, then you'll be able to mount the partition. LVM HOWTO probably can explain how to do it. I've never really liked LVM, hence haven't used it much.
