error: hd0 out of disk

[Simeo]

My computer this morning booted up and just says:

error: hd0 out of disk.
grub rescue> _

Please help? It was running Ubuntu 12.04 64-bit perfectly fine before.

Since it was working before I might try e2fsck on any or all ext partitions.


#From liveCD so everything is unmounted,swap off if necessary, change example shown with partition sdb1 to your partition(s)
#e2fsck is used to check the ext2/ext3/ext4 family of file systems. -p trys fixes where response not required
sudo e2fsck -C0 -p -f -v /dev/sdb1
#if errors: -y auto answers yes for fixes needing response see man e2fsck
sudo e2fsck -f -y -v /dev/sdb1


If that does not work, see this, but it is more for new installs with the issue:

Out of disk error add to grub install disk-module=ata or use Boot-Repair ATA Disk support

I typed "sudo e2fsck -c -p -f -v /dev/sda1" and now I'm waiting for a response from the computer. All I see is a white cursor right under the entry. *waiting*

Edit: 15 minutes later and still no response or sign of what's happening. Is this normal? *waiting*

Did you do that from liveCD?

Is sda1 your ext4 partition?

Yes, I did it from liveCD. sda1 is my main ext4 ubuntu partition.

I'm still "waiting" by the way... :\

Still nothing. It just sits there on the terminal. Anybody have any advice or help please? I can't even mount my hard drive from boot usb to backup files so I could do a clean reinstall.

I assume BIOS sees drive.

What does Disk Utility show. If you click on drive is it green or not? All I really know is drive needs to be green or it is failing.

Sorry it took so long to reply. I had to borrow another computer to have some of the day's work done.

Disk Utility shows a green dot and says: Disk has a few bad sectors

What should I do?

[oldfred]

That Disk Utility says drive is ok is good, but that nothing, grub nor e2fsck can open partition is not good.

Does testdisk open partition or show errors?

Part of testdisk which is in the repositories or most recovery CDs.

Running TestDisk now. Will update as soon as I'm finished.

Edit: The "Deep Scan" is currently at 73% and showing 13 partitions I didn't know about.... if I'm reading this correctly...
