Werner,
Ah, you're using the C= A3070 streamer…
Ok, I know the streamer and I even know this behaviour. Though I have no
idea where this comes from. It's a unique problem of the Calipper
streamer.
I assume there is an error in the streamer's SCSI bus adaption, which
causes the streamer to skip bytes or insert additional bytes.
That you haven't encountered this problem with other software might be
caused by the fact that they're using a different mode for writing the
tape. You can try to alter the block size or turn the "fixed blocks"
option of.
The fact, that the restoration works fine when you're interrupting the
process is a good proof that the backup itself and the restoration routine
both are ok, and the problem is hidden in the SCSI data transfer.
I'm very sorry, that you're disappointed with Diavolo. It's really
difficult to make the software a) fast b) reliable and c) working with all
available equipment.
Diavolo has proven to be very accurate with almost all streamers,
especially DAT streamer. To make Diavolo working with ALL streamers, I
have implemented the SCSI option dialogue, where you can enable and
disable Diavolo's features. Sometimes a feature of the streamer is
detected by the "check capabilities" routine but does not work reliably,
so you have to switch it off manually. This COULD be true for your
streamer.
Though your streamer may be vanilla-of-the-shelf, I never had one to test
it myself, nor has any of my testers. If you're interested (and if you own
a modem), I'd like to invite you to our betatesting program. You then
could get beta versions in our support mailbox here in munich and the only
thing I would like to get from you would be a detailed bug report with
some debug-information of Diavolo (like it's SCSI protocoll etc.).
