The Poly/Mega/Ultradisks from Alpha Systems are nonvolatile - plug into the
cartridge port, and use an external power supply. Unless you're specifically
doing something crazy with the HDV_ vectors, (like some malicious program
tries to write zeros over every sector of a random drive?) there's no way
a runaway program on the ST can trash what's on it. I've got a 2meg Ultradisk,
and it's worked well for me so far. (However.... [Isn't there always one of
these?] There's a catch - I haven't thought too hard about this yet, so the
answer may be obvious to any of you reading this... I originally had mine
set up as a single partition, 1988K of space, (and 60K for the printer spooler.)but found that things flaked out and I lost my FATs after a point. I've now
got it set up as two partitions of near 1meg each, and haven't had any trouble.
Hm... It seemed to claim to be a single-sided disk drive. Perhaps that was
too much storage to be addressed by a 12 bit FAT entry?)

I usually keep my Mega 4 running all the time. Kept my 1040 running all the
time as well. No problems yet, after 2 years or so...

usual disclaimer... I don't even know anyone at Alpha Systems...!  }-)
