I have Arcserve backup copying large backup files (3 Gb files) from an
internal IDE drive to an external USB drive. I get the following error:

Device "[V025-A1-D0:1] Maxtor 6B300R0 f/w:BAH41B70" deactivated by driver
due to device failure.

Any help? I can't mount the internal IDE drive unless I do a reboot.
The USB drive seems fine.
