I have an Amiga 1000. I am getting a lot of read/write errors on my diskettes.
I read a note in Amiga Tech which talked about an Amiga 500 user who had to beef
up his power supply. The symptoms he described are the same as mine. Disks
format and later he gets a lot of read/write errors. I also find that sometimes
the CPU thinks a diskette is write locked when it is not. Anyway. Does anyone
have a suggestion on what I can do about a power supply? I have a Microbotics
Starboard with 2Mbytes and a CLtd. SCSI adapter. I would like to atleast power
the memory board seperately. Any other suggestions for fixing this problem
would be appreciated.

I believe the A1000 has a 100Watt power supply. I think the early A500
problems were due to the fact that the power supply was only marginally
capable of supporting the system wattage. I would check out the disk
drive first. Unless of course both an internal and an external drive
are failing. You might try disconnecting some of the hardware you've
got and see if the drive gets any better.
I recall other people having problems with the write lock hardware on
the A1000. Several people actually had the mechanism fall off inside
the drive.

Dean,
I also have an A1000 with a setup very similar to yours (C-Ltd.
SCSI host/controller and StarBoardII). FWIW, I have not had any
power supply troubles, although I am running the StarBoard with
only 1 Meg of memory installed, which may be tipping the scales
in my favor. I did have to install the extra PAL grounding to
get the expansion stuff to work reliably.
I *did* experience the floppy write-lock error that you describe,
though. Luckily, it was only the external drive that was having
trouble; I took it apart and examined the write lock mechanism.
There is a little arm which makes contact (or doesn't!) with the
write lock tab in the diskette; attached to the arm is a magnet
which closes a small magnetic leaf switch encased in a glass tube
which is mounted to the PC board. It turned out that the tolerances
were off just enough so that the magnet didn't always close the
switch. I carefully and gently pried under the wires of the leaf
switch to move it away from the PC board a small amount, closer
to the magnet. Haven't had a problem since.
