Disk Replicator Problems

In comp.os.linux.misc Kudzy :
We are trying to use a disk replicator to duplicate a Linux disk and
are having problems with the results. At the minimum, the replicator
seems to be using bad sectors/blocks on the target disks when it
should *not* be using them. We have verified with the replicator
vendor that we are using their machine correctly, but still have
problems.

Has anybody experienced problems such as these using a disk
replicator? Do you have any recommendations?

Dunno, never used anything else then 'dd'/'rsync'/'cp'/'sfdisk'
or even simply split a softraid to duplicate disks/systems, no
problems at all. There's no need for any fancy software, which
might not work as expected, your distro should provide you with
anything needed out of the box.

Good luck

Is the disk very old already? 3 years? 5 years? Normal IDE disks
shouldn't have any apparent bad sectors, and the disk already does
bad-sector remapping. When bad sectors starts to appear to outside
the disk (i.e. to your duplicator or a computer), the disk is usually
dying.

It seems that the OP is talking about a hardware device. He wrote:
"... using their machine correctly..."

Personally, I wouldn't buy such a hardware. Like you, I'd use dd,
scp, tar, gzip/bzip2, [cs]fdisk, etc. Those are more flexible and
upgradable than any dedicated device. But maybe the OP is involved in
duplicating disks routinely and hence a dedicated device for that task
would make sense.
