They are allways of the same size: 1247804Bytes=1.2MB

These files are allways images, uncompressed and in tif format.

The destination is not open to any access, wether directly nor through some
fileserving. The source is served meanwhile by a samba server. Stopping this
service during the rsync process on the sending side does not prevent rsync
from hanging up.

These harddisks are 6 month old 200MB ide harddisc drives. So they are quite
new. Nevertheless, since this seems to be the last option to check I'll go
and get some new harddiscs to check for this...
