It may well be that there are SCSI commands that relate only to communication with tape drives, or that are not used in communication with hard drives. It doesn’t matter what software you use, or what drive hard drive, tape drive, etc.

We are backing up to a new VXA-1 tape drive and have encountered no mwc, others appear to have worse luck with this set-up.

Mac OS X Speciality level out of ten: The following products have been discontinued and a software upgrade path for these products will not be provided. When Retrospect attempts to send data to a tape drive attached to the U2B card, a kernel panic occurs immediately.

Posted April 19, How can a piece of essentially Apple supplied hardware, which is otherwise supported in OS X, be unsuppored in the final commercial release of Retrospect. I will ask for a refund unless I get confirmation from Dantz that they WILL support the U2B in the near future with a date of when they expect an update. The Adaptec statement quoted earlier in this thread by John Mayoff simply says that if you bought your card through Apple, look to Apple 2940h2b driver updates.

It appears that there are serious problems writing or reading to tape drives connected to the OEM U2B. I just want to know if Retrospect 5 can backup and restore hard drives connected to this 29402b is a very different question.

Tell me it’s free. I am NOT going to buy another board. The following text came directly from the Adaptec URL below: Thanks to all that responded to this original post.

I will try once more with the following updates to the issue. I have no intention of attaching any backup device to this drive.

It is Apple’s responsiblity. This adapter was heavily tested and failed in every case.


It just seems to have resolved itself after I upgraded the memory to the maximum. Dantz has stated that their product is incompatible with the U2B.

I can’t imagine that Retrospect would have a problem with backup sources on hard drives attached to this card. That is a problem for some, but it is not a problem for me. I don’t mean to sound harsh, but it’s simple concept.
