WORKING WITH A 5¼" DISK DRIVE by Richard Karsmakers
Since of couple of weeks, I am proud to have a 5¼" disk drive in
my posession (included in one of those Cumana 3½"+5¼" drives).
Originally having hated those very floppy floppies, monetary
matters made me switch to one of those good old drives again -
after all, the 3½" disks cost about 5 times as much as those very
floppy ones.
Many people, having bought one of those 5¼" drives, will come up
with some questions. I also came up with these questions, and I
have found an answer to most of them.
1) What is that strange click that I hear every time when the
drive starts working when a 5¼" disk is actually inserted?
Answer: That is the so-called "head load". It may sound
irritating, but it's perfectly harmless. It can be disabled by
opening the drive, inserting a disk and using a small screw to
keep the head permanantly where it is with that disk inserted.
2) How can I boot from drive B?
Loading accessories CAN be done, using a program called
"Freeboot" that I got from our French distributor. I busted this
program, however, so that I will have to wait another while to be
able to do it again. Bootsector loading is quite impossible.
Those are the answers with regard to software solutions, but
there's a hardware solution, of course. You can make a switch on
the drive select A and B leads in the plug that fits in the back
of your computer. Switching these causes drive B to become drive
A and drive A to become drive B. Booting from 5¼" is then
possible. If you intend to make a switch there, make sure you
turn off your system if you switch (I don't know what happens if
you don't).
3) Can I use white label disks?
Of course you can, but you'd better copy everything to 5¼" with
verify ON in that case (I really like FCopy 2.0). And disks that
use 10 sectors per track can only be copied to better quality 5¼"
disks.
That's all there is to tell. Especially the 'head load' makes
many people think that something is wrong with their drives,
which apparently isn't the case. I can advise everybody to get
his hands on one of those 5¼" drives - it really makes a whole
difference in the wallet!
