If only sane-find-scanner is used (not scanimage) there are only these
two commands sent to each existing SCSI device (/dev/sg*). If both
/dev/sga and /dev/sg0 exits, the device may be querried twice but not
more. I would be sirprised if that's really the cause of the problem.

If you (the original author) used a very old version of SANE it might
be possible that a bad link destroys data, e.g. "/dev/scanner ->
/dev/sda". I have never actually tried if that really "works". But
checking if there is a link /dev/scanner shouldn't harm.

I have never heard of anyone else having problems with sane-find-scanner
and hard discs or disc arrays.
