[Wlug] Using Knoppix to copy an NTFS drive

[Chuck Noyes]

Hi All,

I have a drive that sounds like it's about to fail (making strange
noises and occasionally not booting), so I want to copy it to another 
identical drive. The drive has 1 NTFS partition on it - I very
occasionally run Win2k.

I booted up the 5.0 KNOPPIX CD and tried dd if=/dev/hda of=/dev/hdb.
There were no error messages and after about 30 minutes the 'dd'
finished. However from KNOPPIX, I can't mount the new drive. the mount
command (sudo mount -t ntfs /dev/hdb1 /media/hdb1) fails with:

"Couldn't mount device '/dev/hdb1'. input/output error - mount failed".

The original drive (/dev/hda1) mounts without any problem.

If I use the fdisk utility and look at the partition table, there are
no differences between the hda and hdb drives.

Any ideas how I can solve this problem??

BTW: The qtparted utility on the KNOPPIX 5.0 CD and DVD fails with a
"floating point exception" error.

TIA,
-Chuck
