Change Permissions on a new hard drive to allow

[mtyoung]

I recently added a new hard drive (/dev/sdb1)to a dual boot system. The 
new drive works fine from XP, but in Ubuntu I can only read. In XP I use 
"Ext2 IFS version 1.10c" to access the Ext3 drive.
http://www.fs-driver.org/extendeddl.html

The drive was formatted as NTFS originally, then changed to Ext3.

Owner and Group are Root, Owner has all privileges, Group and Others can 
read and execute only.

How do I change the permissions for a hard drive?  Everything I find is 
for directories and files.

TIA

Below are fdisk and fstab for this system.
