[SOLVED] uninitialized harddisk

divyashree · 01-18-2011, 01:20 AM

One linux machine suddenly shows insert boot disk and press enter. So I think grub may be corrupted, as the hdd is detected in the BIOS. So now I insert the dvd and goto rescue mode. Now it shows the harddisk is uninitialized and wipe out all data iif initialized.

It is centos 5.3 ,what could I do now ?

Hello,

There's a big difference between a corrupt grub and a disk showing as not initialized. If you think your grub is corrupt then you can try to reinstall it from the LiveCD by mounting the disk, /dev and /proc and enter in a chroot environment to execute grub-install, like this:

Code:

mkdir /adirectory_to_mount_your_disk
mount /dev/<yourdisk> /adirectory_to_mount_your_disk (find out with fdisk -l)
mount --bind /dev /adirectory_to_mount_your_disk/dev
mount --bind /proc /adirectory_to_mount_your_disk/proc
chroot /adirectory_to_mount_your_disk
grub-install --recheck /dev/<yourdisk>

If that fails, then try to mount the disk normally when booted from LiveCD and copy the contents you need to USB/NFS/... and reinstall. When you're unable to mount the disk then you might have a hardware failure.

Kind regards,

Eric

Yes it was a hardware failure.

No, sir. I was unable to recover data. And I had already backup of my data. Thanks.
