Re: during retrospect rewind the tape...
Actually this allows me to attach the tape drive to the power plug on the back of the CPU so it shuts down with the system. Without the wait it will power it off DURING the rewind.

RE: during retrospect rewind the tape...
This is a good example of when to use the asynchronous scsi calls. While the call completes you can be doing waitnextevent so the computer is not FROZE during this time.

RE: during retrospect rewind the tape...
Reply to: RE: during retrospect rewind the tape... Lionel, Retrospect will now always rewind your tape when you quit the application to (among other reasons) prevent problems writing an end of data marker. We were finding that with certain tape drives, if you told Retrospect (in earlier versions you could do this) not to rewind your tape on quit, it would not properly write an end of data marker, which would make it impossible to append data to the end of the tape. The reason it takes so long? My guess is that Retrospect is waiting until the command that it sent to the tape drive (to erase) has completed before freeing up the machine for other tasks.
