Is there a repository to where I can upload diskette

As others have indicated, the Internet Archive seems to be an acceptable
place.
There are some other places that are more subject matter specific. The
A.T.C. comes to mind for IBM PS/2 stuff.
What format is in widespread use these days?
I have long used a simple `dd` raw image created at the Linux command
line. There are a number of tools that are compatible with the same format.
I use DiskImage (Ver5) and Dave Dunfield's
ImageDisk (Ver1.17) -
both work well. I seem to recall that DiskImage is a commercial
product and ImageDisk is still available for free.
When I inquired about archiving PC disks used in 'DOS / 'Windows
(compatible) computers in the past, I learned that `dd` raw images and
possibly an archive (e.g. zip) of the files on said disk is usually
sufficient. It seems as if you need to start getting more complicated
when you start playing outside of 'DOS / 'Windows (compatible) world.
Not sure that IBM would use cheap *anything* in their
equipment.
I don't know that RIFA was cheap, in any sense of the word. I think of
it as a line of components that had a design flaw that likely results in
an energetic failure at some point.
A word of warning, the "inertial rotation"
procedure was great for
smaller drives, but you may break your arm applying this to an ESDI :-)
Yep.
I've done the "inertial rotation" a few times in the past. A few of
which were full size (read: 3" x 5ΒΌ" x 6+" drives), which usually meant
setting it up side down on a table (often with something smooth between
the table and drive) and using both hands to twist on the motor axis
specifically to avoid injuring myself.
Aside from dismantling the drive, not really. Just
cross your fingers
and pray. Usually not a problem. I have an ST225 which had been
powered off for two decades and it came up fine in my DEC Rainbow!
ACK
It is my belief that these batteries should still be
available from
somewhere. If I think of it when I get home, I'll dig out the box
and relay the model number. Provided that the box is still where
I remember.
Thank you.
As others have mentioned, the batteries are available in some common
locations. I don't think it will be too difficult to acquire one.
Seeing as how the old battery is still in there I have the make and
model. Then there's all the documentation around the web.
