I am running FreeBSD 5.4 in VMware using USB 1.1 external HDD as a disk,

when performing heavy operations, such as rsync of a 1 GB database dump
file.
All references to the problem I found point out hardware failure. Could,
however, the problem be simply that the I/O does not manage to let the
request go through within the 20 seconds wait time and that the hardware
is OK (apart from the fact that I/O is slow? And - is this message just
a notice, or does it mean that I get data corruption?
Yes, it just means "operation did not complete within the arbitrarily
chosen time period", and by itself it doesn't mean there exists any
further problem. If the operation didn't complete because the drive
threw it away, has bad blocks, etc, that would be a problem. In your
case it's likely to just be the slow disk.

Kris,
