From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike McCarty Subject: FORMAT floppy: Drive_IO error (longish) Date: Thu, 30 Mar 2006 02:52:44 -0600 Message-ID: <442B9C5C.1030209@sbcglobal.net> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-msdos-owner@vger.kernel.org List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: FreeDOS 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. $ uname -a Linux Presario-1 2.6.10-1.771_FC2 #1 Mon Mar 28 00:50:14 EST 2005 i686 i686 i386 GNU/Linux In the emulator...
