	I own a system with an A500 with 1 Meg, the std. old monitor, a
serial MIDI interface, a Zoom modem, and an A1010 external drive-- nothing
fancy.  My problem is as follows. Under normal use and under most
circumstances, the system operates fine for disk formatting and copying, all
the usual read/write tasks. However, sometimes during a write to the A1010
(I don't THINK this has ever happened during a read operation), the A1010
wil suddenly begin to grind, as if searching for something. It then gives me
a requester that reads, "VOlume (whatever) has a read/write error".  After
that, regardless of whether I click on retry or cancel, it says something
like, "Initialize Failed, Disk is unreadable."  Then, "Disk Structure is
Corrupt; use DISKDOCTOR to recover it." After that happens, the disk will be
unreadable by either drive, and must be reformatted. 

	What's going on here? Is the drive fucked up? Have I somehow bought
three boxes of flopies in a row with a 20% failure rate (I use only 3M
diskettes)?  Is there something in software that's eating disks randomly (I
kinda doubt this is a virus; I don't download anything but ASCII, and never
from BBSes)?

	It's cost me a bunch of disks and a lot of very expensive connect
time (2/3 of the way through a Kermit receive-- GRUNCH GRUNCH, BARF, GURU.
AAGH!).  I'm horribly paranoid about making backups now; I don't know if
they'll take.  The problem only happens once in a while; I can come back to
the Amiga the next day and it'll be fine. Then, days or weeks later-- BANG!
Got me again!

	I'm running WB1.3 with DMouse, usually.

	If anyone has any ideas, I'd like to hear them. Please Email me as I
can no longer receive news; a friend is posting this for me. My address is

Thank you in advance,
