I have a hard to replace dsdd floppy disk that
produced a
screeching noise while attempting to read it on a win98 box under
Dos using a Dos program. I quickly removed it and tried to read it
on another Dos box also with a HDFDD. No screech but only the
directory was readable, not the contents. I checked the original FDD
again using a scrap dsdd floppy and had no trouble with it.
Anyone have any thoughts as to what would have caused this ?
Whenever I have heard that horrid squeal, it has been followed with
the disappearance of the magnetic media on a track or cylinder. :{
And whether the disk is salvageable ? I'm
reluctant to run the disk
again on any box till I explore the options, lest I damage it
further.
It was an old DRI PC-install master disk for GEM.
The first thing that you want to do as make several image copies of
the disk on a drive with known clean heads and using a utility such as
AnaDisk that will make a track-by-track copy of it. Then work on a
copy!

AAARRGH !!
There go my hopes for a tasty profit. An identical set just sold for
$205 on E-Pay. I know the actual install and later versions are
available on the Unoficial CPM site, I have several installed on one
of my boxes so it isn't lost, but DAMN !
I guess it would be unethical to steam the DRI lable off. :^(
Oh well, maybe a copy of the master disk along with the original
nonfunctioning one will suffice.
thanks guys
