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) —————————————————————– Device CLtd.device /* Set Device */ Define Handler SCSIf.handler /* Define Handler code file name */ Load Handler SCSIf.handler /* Load Handler code segment */ Define Driver HardDisk.driver /* Define Driver code file name */ Load Driver HardDisk.driver /* Load Driver code segment */ Initialize Handler 100 /* Initialize Handler */ HandlerCode SCSIf.Handler /* Code Segment Name */ TaskName SCSI_Bus_1 /* Set Up Task Name */ TaskPriority 15 /* Handler's Task Priority */ StackSize 400 /* Stack Size */ HostAddress 7 /* Our SCSI address number */ Flags Arbitrate /* Enable Arbitration */ Flags NoDisable_IRQ /* Do Not Hold Off Interrupts */ [ MORE ]

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