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
