The command I used was: "sudo dd if=/dev/hda of=/dev/hdb bs=512 conv=noerror,sync" This worked perfectly. I now have a duplicate NTFS drive that I can mount from KNOPPIX and Linux. I can also run Win2k from when I need to (not very often). Thanks to Chuck A. and Jamie G. for their help. -- -Chuck

reiserfs corruption....

by Eric Stein

Hi all, After a nasty power problem, I have corruption on a reiserfs volume. What I did: http://toba.ath.cx:724/~eastein/reiserfsck.txt I think I may have a damaged drive. The scariest prospect: Bad root block 0. (--rebuild-tree did not complete) Any ideas? Eric

Hi Chuck, I don't know what the default block size is for dd, but maybe you could try adding "bs=512" to the dd arguments, so that you're copying on sector boundaries. I can't explain why this would help (if it does), its just a hunch. :) Also, maybe you could you turn off DMA to one or both drives before doing the dd. "hdparm -d0 ..." or something like that. -Jamie

Using Knoppix to copy an NTFS drive

by 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

Seeking help with xine

by Walt Sawyer

Hi all, I'm having some trouble with xine. It used to work, but, for no apparent reason, I get error messages that say "-xine engine error- There is no demuxer plugin available to handle /xine-ui_logo.mpv." and "There is no demuxer plugin available to handle whatever file that I tried to open". Can anyone help me? Thanks! Walt
