George;
Eric has given you some good points. I have three SyQuests used with
various machines (two internals – in A2000 type machines) and a Mass
external (the newest SyQuest).
Be aware that SyQuest has produced some drives with really bad firmware on
the drive. Firmware that did almost anything but honor the scsi
specifications. Thus you can get into some really bazzar behaviour
problems and reach the point where you are beginning to question your own
sanity.
The "as shipped" scsi ID for the A3000 internal drive is 6 but I would
recommend that you do what Eric suggested and make sure by running
HDToolBox (DO NOT change anything with HDToolBox). When HDToolBox first
comes up, the window will list the scsi devices found on the system
including the scsi address for each device.
HDToolBox is quite a powerful tool and like most powerful tools can wipe
out your HD and all partitions in an instant.
One question that you might want to think about before setting up your
system is how do you want the system to behave? If you leave the internal
drive at 6 and add the SyQuest at some lower value (and in that case it
HAS to be a some lower value) then the Amiga will be looking for the
SyQuest everytime it boots. If you do not have a cartridge in the drive
(or the drive is off) then it will take Ami quite a few extra seconds to
boot.
If you re-address the internal drive to something lower (ie: 5) and put
the SyQuest higher than the internal drive (ie: 6) AND NEVER change the
internal drives configuration with HDToolBox when the SyQuest is present
then Ami will not delay when booting. You would then have to run
something like "scsimounter" (that Eric mentioned) to mount the drive.
You really need that utility regardless of how you decide to set the
system up anyway.
I use the "device" name of SQ0: for all SyQuest cartridges. The SQ
reminds me that it is a SyQuest cart. and the zero is because I started
using those things long before I realized that there are few restriction
on Ami device names. A good reason for sticking with a single device name
for all carts is that the device name of the cart that is in the drive
when the drive is mounted is device name that will be used until a reboot.
Thus, if you used Sq0, Sq1 … Sq'n' for cartridge device names when you
set the cartridges up with HDToolBox then the device designation for your
syquest drive would depend upon what cartridge was in the drive when it
was first mounted. Believe me, this can be a problem for you later on.
I don't know if I am making the issue clear or not but let me try this:
How would it be if DF0: could have a different device name everytime you
booted the computer? You can always use a volume name when you need to
deal with a specific disk (and that will be true for the SyQuest also) but
it is very handy when the device name stays constant for a particular
drive. Since, unlike DF0 (1,2, or 3), the device name is set by reading
the RDB on the disk platter, it is up to you to keep it constant.
In as system with multiple SyQuest drives this is still not a problem as
the system will automagically append a "suffix" to the device name of a
device that is the same as an existing device. So if you had two SyQuest
drives and each had a cartridge with "SQ0" as a device name then the first
one recognized would be "SQ0" and the second would be "SQ0a".
