FORMAT floppy: Drive_IO error (longish)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


I have a floppy which I knew in advance had errors on it, but
just for the sake of trying out all the tools, and also to see
what got put on the disc by FreeDOS, I tried to format it.
The format ran for quite a long time, like tens of minutes, then
there was what appeared to be an internal error of some sort.

It is the fact that an internal error seemed to occur that
concerns me. Also I am somewhat concerned that one more bad
sector was reported in the total than in the detailled list,
though much less so. Mostly, the latter is likely just a
mis-count, but it might be related to the failure.

Here is the information I collected. Is there more information
I should collect, and where should I send it (if not here)?

I was running xdosemu under Fedora Core 2, the floppy
was *not* mounted under Linux. This is a 2.7 GHz Celeron
single processor Compaq Presario machine with 256MB RAM.
