Norton Ghost,USB 2.0 enclosure, 27mb/minute clone took 9 h..

A clone of my internal drive to an external Western Digital drive in a
USB 2.0 enclosure took over nine hours to copy 17gb. The transfer rate
never exceeded 29mb/minute. Clearly, this is not USB 2.0 rates, but
within the acceptable USB 1.1 rate as described on the Symantec
website.

I am running Windows XP with a LiveUpdate-current-version of
SystemWorks 2003.
Windows has correctly identified the enclosure as a USB 2 device.
What am I doing wrong?? How can I obtain USB 2.0 transfer rates?

SystemWorks 2003 Ghost runs under DOS, so Windows environment does not
apply. How fast can you copy large files to/from USB drive in DOS?
WinPE and Ghost32.exe might perform much better.

I recently trialled Norton Ghost 9 and it worked really fast; see recent
post.

This version runs in Windows and builds upon Drive Image from Powerquest
whom Symantec acquired.

When I used the earlier version I got about 40MB/min and I found a
section in the manual which said this rate was expected - very poor!

did you copy the whole drive or volume, or just data and app
directories? That is, can you restore the full drive or partition from
your backup file or clone, or would you have to re-do the OS (and apps)
manually?"

one all-in-one solution for a little more (comes with ejectable
drive bays):

Here, you can hot swap the bad drive and the system will
automatically reimage the new drive.

As for the drive format, the ones I've worked with (Promise Tech,
Adaptec, built-in motherboard), don't do anything strange with the HD
format when in RAID 1 (mirror) mode. You can disconnect both from the
RAID IDE channel, attach either back to a regular non-RAID IDE channel,
and they work just fine. It's only when you've got them in striped mode
(RAID 0, 5, etc.) that the drive format will change and be unreadable
when you attach only one drive to any non-RAID IDE channel.
