Does anyone recognize these symptoms?
I'm running BTNTape 2.0 on an A2000 / A2090A to a Cipher 540 1/4" tape
drive. After fooling around with the order I load the cartridge, mount the
device, etc, I can get TAR to read from the drive, but after some
(variable) number of blocks are read, the system locks up solid. No
pointer, no keyboard, no screen updates, no GURU, just locked. If I do a
slower operation, like type TAPE: opt h, it will read through the tape
without hanging. If I up the blocks/read, etc, to make it run faster, it
locks more quickly. Seems to be some sort of timing problem, as the number
of blocks that get read before it locks varies anywhere from 10 to 1200.
This is so tantalizingly close to working that it's driving me bats....
Any suggestions/ideas/hints??? Thanks....

I can get TAR to read from the drive, but after some >(variable) number of blocks are read, the system locks up solid. Yes, I have seen the same thing. I was using BTNTape 2.0 with a 525 Meg Archive 1/4" tape drive in a 2500/30 with a 2091. When I ran with the default handler setups, it would take a while to lock, but when it was optimized for speed with my drive, lockup would occur quite quickly. I hope someone can answer how to fix this since the new BTN is about 4x faster than BRU with my configuration and I desparately need FAST archiving. %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% % ` ' Mark Thompson CONCURRENT COMPUTER % % --==* RADIANT *==-- mark@westford.ccur.com Principal Graphics % % ' Image ` ...!uunet!masscomp!mark Hardware Architect % % Productions (508)392-2480 (603)424-1829 & General Nuisance % % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
