[comp.os.cpm] Tandon disk drives lose upper head

jeffj@pedsga.UUCP (09/26/88)

[spritzensparken!]

I have had two Tandon TM-848-02 floppy drives fail recently.
(half height DSDD 8")
Both failed the same way.
They worked as double sided, then the upper head failed.
Now they cannot read nor write the upper side,
but function okay as single sided.

The heads look fine.
What went wrong?  Can I fix it easily and cheaply?
(Remember that new drives are $50 at computer fairs).

Thanks for your assistance.

I have this seen more times by Tandon floppy drives.
The only thing you can do to let this not happen is to
step the drive so fast that the haeds are continous moving.
In many computers the steprate is slow that any (old) type
drive works.
