Repairs, repairs...
===================

Today I  had some time for  retrocomputing. I decided to  try to repair
some stuff.

Long  time  ago  I have  got  a  SCSI  floppy  drive for  original  SGI
Indigo. It  never worked. If  I'm not mistaken  it even didn't  show in
diagnostics. Thus  I have decided to  replace the drive with  a new one
(SGISs use  special sleds for all  drives - and every  SGI machine used
different ones).

When disassembling  the drive  I have  found that  some cables  are not
connected at all and that pins of one connector are terribly bend. So I
have fixed  these issues and  inserted the drive  to the Indigo.  To my
great surprise the machine booted normally  (no SCSI errors at all) and
the  drive was  (properly!) detected  by the  IRIX! So  I inserted  the
floppy medium.

The computer  told me that  the floppy was  not formatted and  asked to
format it. In short: formatting failed. Insertion of actually formatted
medium ended  with the same  dialog. I  tried to disassemble  the thing
once  more but  the reading  heads seemed  to be  absolutely clean  and
everything seemed to be intact. Thus I have no idea what is wrong.

I have tried to replace this drive (a TEAC one) with a SONY drive (from
the Sun workstation). It does not fit the sled (the cable connector has
different  position and  orientation  so  I was  not  able  to mount  a
connected drive). Now  I'm thinging about finding an empty  SCSI box to
try to  use the SONY as  an external drive.  I should have at  leas one
somewhere, I think.
