Wanted: SCSI Cont. Facts
5 messages in this thread
Lloyd,
I need more hard drive space and am thinking about the SyQuest. I have the
KRONOS controller. What do you mean about a "special" operation to format
the drive? How's the speed of this setup? Is DISKCHANGE an executable
program on the Kronos software? I'd appreciate any of your thoughts on this
matter. Thanks
John
John,
The "special" operation comes when you want to format a new cartridge –
the Kronos FORMATTER won't allow you to format a MOUNTED drive. So you have
to BOOT from the Kronos Utilities floppy (with the LEFT mouse button
depressed so the hard drives don't automount) to format the new cartridge.
DISKCHANGE is an AMIGADOS command. So if your SYQUEST is installed as
DH1: you'd DISKCHANGE DH1: after you change a cartridge. It is really no
big deal. I don't treat those cartridges like floppies, so I've never had
to DiskChange much. *NOTE* – make SURE you FORMAT and PARTITION your
cartridges IDENTICALLY! Personally, I format each cartridge as ONE
partition, and use SUBDIRECTORIES to organize things.
Speed of the Syquest is pretty good. A little better than the Seagate
157N-1 that I have.
Assuming you already have a hard drive as DH0:, and are adding the
Syquest as DH1:, this should be ALL the info you need to use the Syqest
with your Kronos:
Kronos DEVSETUP for DH0: (Seagate 157N) and DH1: (Syquest 44 meg)

Lloyd,
thanks a million!!! I'll let you know if this works when I get the
Syquest.
