>Can one add a MacBottom SCSI to the back of a Jasmine 50? Successfully?? 8^)
I don't know if connector-wise it will work but I have connected
a warp9-photon30 to a LoDown20 to 2 homemade 106mb (adaptec controller,
fujitsu raw drives) and they all came up fine. 262+mb.. :-)
This was on a plus. 4.2 system 6.0 finder
Pretty loud but nice when they are all winding up...rrrrrRRRRRR!!
And what about backups? I never did it but I believe that would
be 140 or so floppies...
But this setup was just an experiment. Do others in net-land
have disk capacities in this range working? Will some limit get
hit somewhere? Bad blocks were also a pain. I found on the homemade
drives that I had to run many,many passes looking for bad/marginal
blocks before formatting and loading up the file systems.
Also, it seems that if a bad block comes along later (I'm using the
SCSI driver/utilities that came with my warp9 drive) there is
no clean way to handle it..(backup,re-init,restore)
the file system just goes slowly insane. Lost directories,
"can't read" messages etc.
The adaptec controller knows about putting a pre-formatting
bad block list on the drive so the controller will remap on the
fly but as I said, this must all be done before the file system
is laid on the drive. Comments? As I just admitted (and I'll get
hung for this no doubt |-p ) is it legal for me to use the warp9
supplied driver/installer to run other home-built drives in MY
possession? I did buy the warp 9 drive w/driver and utilities.
No license agreement was shipped with the drive pertaining to
the SCSI driver.
And another thing...I usually run with 1 106mb drive only and when I
return to the finder (especially when the application has deposited
a file with a new creator type) it seems to pound at the desktop
file for a long time...as much a 30 seconds or so.

Before I bought Disk Express (slow, but it works well), a friend loaned me a
Rodime 20 plus drive to defragment my SE's internal drive (ie copy everything
over, reformat, copy back the other way). Both drives worked fine with no
problems, SE drive SCSI address 0 (I don't think it's changeable), and Rodime
drive @ SCSI address 3.
I'd love to see a Mac with 4 hard drives, but I suspect it would be cheaper to
buy Priam's 337Mb drive if you really need that space....
