is it on the primary IDE channel with the harddrive? if so then the device file for your harddrive should be /dev/hdb. how many partitions does it have? say you have 3 partitions, each partition will be represented in linux as a device file, such as (in this case): /dev/hdb1, /dev/hdb2, /dev/hdb3.
if you have only 1 big partition then it will of course just be /dev/hdb1.
first, figure out which partition you want to use. you also know that the filesystem of the harddrive is 'ntfs'. so the next thing to do is to learn how to 'mount' the device.
first make a folder (as root), such as /mnt/BackupHD. this will be where you 'mount' your NTFS partition.
next, look at 'man mount' in a terminal window to learn how to 'mount' a filesystem.
in short, with the above assumptions i have given, you should be able to run the following command as root:
Code:
mount -t ntfs /dev/hdb1 /mnt/BackupHD
and then browse to this /mnt/BackupHD with your GUI and see your files. note that you can only read from ntfs partitions, and not write.
if this command does not work post the output of the command or read the manpage as suggested above.
good luck
edit: if you recieve that error when installing the software, can you find the software for x86_64 ie 64 bit CPUs?
