Re: HD Partition Lost??

Yes, I downloaded the Maxtor diagnostic program and installed to a diskette. It reports that the drive is failing and to back up right away returning a diagnostic code for an RMA. Oh well, guess it really is hardware. I will be dd'ing it over to another drive and sending this one back. Then I'll work on it from there.

What would be the exact syntax for the dd command for the entire disk as you suggested? I will be installing a parallel drive in the morning, also a 160GB drive as /dev/hdc with the bad one being /dev/hda. The bad drive is nowhere near full, but is the max file size a problem still? I shouldn't do just partitions instead? Although the one with the actual problem is a 100GB partition, although only about 20% full. Around 22 Gig all together on the drive.

Thanks for the help,

being not a professional but a normal user i think this really looks
like some hw issues. so i'd suggest better to copy (dd) all the data
from the disk, as long as you have time to. every additional use of the
disk may cause its final death.

i wonder why your other partitions *seem* to still be ok (e.g. "mount"
and using its data then succeeds)...

Ack! I've had too many failures with Maxtor disks.

Anyway, use conv=sync,noerror with your dd command, preferably to an
identical disk. Do the entire disk /dev/hda. Yes, it will take a very
long time, but you have no other recourse if you want maintain all your
data. Then fsck the new disk. Fsck on the bad disk may just make matters

Download Maxtor's ide utility & see if you can fix the bad one - may
require a total disk rewrite.

Nothing unusual about the other partitions being okay - just a matter
of location of the sectors on the platter(s). Be suspicious of the
entire disk though.

You may as well do the entire disk:

dd if=/dev/hda of=/dev/hdb bs=1k conf=sync,noerror

Install the new disk as hda & run your fsck on hda3.
