"Disk read failed" error

I have MD 9.1 as a dual boot on a Win2K machine and I'm trying to clean up my config files. My windows stuff is on a separate, primary physical drive. Mandrake is on a secondary, slaved drive.

 

Each time that I boot I get the following error:

ldm_validate_partition_table(): disk read failed

It doesn't tell me which partition failed. I'm guessing it's the NTFS partition that contains my Win2K C: drive, since I can't see anything on it, but how do I verify that it's that and not some other partition that it's complaining about? If it's the NTFS partition, what changes do I need to make so that it's readable?

 

TIA.

I am not clear: your machine is booting but your windex drive is not accessable?

Correct, from within Linux the Windows partition (which is on a separate physical drive on the same machine) is not accessible. It seems to be mounted, but shows as empty. It boots fine into Win2K, but I can't see any data on that drive when I boot into Mandrake.

Are you using ntfs on the windex drive? It may be a sector failure that windex is working around but linux can't, perhaps where the partition table is being stored!

ldm_validate_partition_table(): disk read failed

This usually comes from a USB Compact Flash drive or ZIP drive. Its some kind of bug, but does not affect the use of the drive if configured correctly and supported.

 

As for seeing your windows drive --- does your fstab file have an entry for windows ?

Scoopy's correct! :woops:  I forgot about the usb problem. If you want, post your /etc/fstab.

OK, thanks. I'll assume it's just a USB device (there's a couple of Flash card readers that do not normally have a disk inserted). For the sake of completeness, here's my current fstab. Thanks to everyone for their assistance and comments.
