I am a new beee, and probably out of my depths.
I dual booted Ubuntu 12.04 on a machine already running windows.
I eventually dumped windows, and used Gparted running off of the Ubuntu Desktop LiveCD to expand my limited hard drive space.
In the process I believe I may have messed up my partition table.
I believe I have my primary partition running within an extended partition, which may be a problem ?
Exterior hard drives, which before I repartitioned would mount as read-only, now won't mount.
When entering sudo fdisk -l
I get this:
Disk /dev/sda: 40.0 GB, 40000000000 bytes
255 heads, 63 sectors/track, 4863 cylinders, total 78125000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x9dc96e9e
Device Boot Start End Blocks Id System
/dev/sda2 2048 78123007 39060480 5 Extended
/dev/sda5 4096 77080575 38538240 83 Linux
/dev/sda6 77082624 78123007 520192 82 Linux swap / Solaris
UPDATE: more info.
So, I am basically trying to figure out why my external drives won't mount anymore. And I suspected that had to do with the repartitioning I did, and a messed up partition table, but perhaps I'm wrong.
I was asked in the comments for dmesg | tail before and after adding a device:
Before:

Also, when I pull up my partition table with my WD external drive attached, underneath the partition table I get this:
Disk /dev/sdb: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/sdb doesn't contain a valid partition table
The other external drive I am trying to connect is a Glyph GT050Q hfsplus which yields similar output.
Any help is great appreciated !

, plugging in an external disk, and typingdmesg | tail
again. New entries will relate to your plugging in the disk, and may contain clues about what's causing the problem.
