Failure to recognize hdd in Ubuntu 10.04


Hi:
I have Ubuntu 10.04 on a 500gb WD hdd and a second WD 500gb as my music drive. The bios sees the drive with my music but I cannot access the drive at all after booting up, i.e. I can't see the drive at all. I searched on here awhile and looked at the "similar threads" link but didn't find anything that seemed to answer this. TIA!

type this in terminal:

Code:
$ sudo fdisk -l
See if it shows up there... if it does, than its just a matter of mounting the device... or adding it to your fstab...

but, one step at a time... does linux 'see' your device after you type in that command?

Thanks for the reply. Here's what shows up in the terminal output when I run that command:

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0001394f

Disk /dev/sdc: 500.1 GB, 500107862016 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x2d037b05

Disk /dev/sdc doesn't contain a valid partition table

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000220d2

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 31092 249746458+ 7 HPFS/NTFS
/dev/sdb2 31093 60801 238637542+ 5 Extended
/dev/sdb5 31093 60050 232605103+ 83 Linux
/dev/sdb6 60051 60801 6032376 82 Linux swap / Solaris

I'm thinking my music drive is the one that returns " Disk /dev/sdc doesn't contain a valid partition table". The third drive listed has Win XP on it and I can access it fine. It is usally in a different machine: I plugged it in to see if it was visible.
How do I mount the drive, as you mentioned? This problem started when I upgraded from 9.10 to 10.04, btw. The drive was available without any extra steps, i.e.; it just showed up and was accessable from the desktop or "places".

Thanks, Jeff.

"No valid partition table" sounds like a drive that has RAID or LVM on it. Are you sure that the drive wasn't part of either before you installed 10.4?

It was originally a WD 500gb hdd that came in it's own usb enclosure. I took it out and installed it in my case to streamline my desk... I'm sure it wasn't part of a RAID. Would 'LVM' be related to it formerly being in a usb enclosure? Thanks, Jeff.
