I'm having a great deal of difficulty with an external hard drive. I'm currently running a dual boot system (XP Service Pack 3 and Ubuntu 11.04 Natty Narwahl) on a Dell Inspiron B120.

I'm trying to set up a new 80 GB Hitachi external HD. Using GParted, I formatted the drive and set up the partitions. The partitioning scheme is as follows

• 10GB NTFS Primary,
• 2GB Linux-Swap Primary,
• 50GB FAT32 Primary,
• 12GB Unallocated.

After applying those changes, I went into Disk Utility and the HD appears along with the correct partitions. When I try to mount the volumes for partitions 1 and 3, I get a pop-up stating:

Error Mounting Volume
An error occurred while performing an operation on "Home"
(Partition 3 of HTS548080m9AT00): The daemon is being inhibited.

When I try to to check the filesystem I get a pop-up stating:

Error Checking filesystem on volume
An error occurred while performing an operation on "Home"
(Partition 3 of HTS548080m9AT00): The daemon is being inhibited.

Throughout the time that I'm attempting to troubleshoot the problem, the external drive light is on and blinking. With my frustration hitting a boiling point, I try to shut down the drive and remove it so that I can plug in a different external HD that works PERFECTLY.

However, when I try to shut down and safely remove the drive, I get a pop-up stating:

Error Detaching Drive
An error occurred while performing an operation on "80GB Hard Disk"
(HTS548080m9AT00): The daemon is being inhibited.

Can anyone tell me what I'm doing wrong? I'm a newbie and not that skilled with terminal commands, so please dumb it down for me if you request specific command output.
