Hello everyone,

I have a 1040ST with an internal double sided drive which seems to have an
interesting problem.  One day, I found out that it couldn't read any
of my disks except for a couple.  So, I downloaded some utilities
to my hard drive and did some tests using disktbox.  First, I would 
put a disk into the drive and double-click on the drive A icon.
this would get me a dialog box saying that the drive isn't accessible.
then, I would use disktbox and read the boot sector of the disk, and
it would read fine, then I exited and double-clicked on the drive
icon, and I would be able to get a directory of the drive and the
files on it were ok!  However, running a scan a few times on the disk
would display bad sectors inconsistently.

So, I ran a drive speed program to see what the speed of the drive is.
It was something like 304.56rpm.  As I recall, the speed should be
around 300rpm.  Could this be my problem?  

If the only solution is to replace the drive, I would like to find out
which drive mechanisms work the best, and where to get them.  Are
there any other solutions?

Please email to me, and I will summarize if there is any interest.

Thanks,

Maurice
