USB disconnect during heavy I/O

I have a 160G USB 2.0 drive on current FC5 32bit system. During periods
of heavy I/O, it is disconnected from the system. All the failures
until today were occurred with the heavy I/O on the USB drive. Today, I
experienced the same failure during heavy nfs load on my system and
minimal load on the USB drive. I didn't find others reporting the same
problem under the same circumstances. I have an encrypted partition
(sda3) on the drive mounted through a crypto loop device. The USB drive
is quickly redetected. The fat32 and ext3 partitions on the USB drive
are unaffected. Anyone else seeing this?
Best regards,
Sky Wavrek
