Red Hat Bugzilla – Bug 75030
floppy drive fails to mount floppy disk
Last modified: 2008-08-01 12:22:52 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3) Description of problem: This is an IBM laptop (T22, 2647-9EU) with modular bay. It detected the cdrom just fine and installed redhat-8.0. But when the floppy drive is put into the bay, and a floppy (readable in other linux machines) is placed in it, it always fails to mount. The drive is ok as win2000 can read floppy from that drive. During boot (as shown by "dmesg"), the floppy drive is detected as: ide-floppy driver 0.99.newide Partition check: hda: hda1 hda2 < hda5 hda6 hda7 hda8 > Floppy drive(s): fd0 is 1.44M FDC 0 is a National Semiconductor PC87306 NET4: Frame Diverter 0.46 RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize ide-floppy driver 0.99.newide When I replaced the cd-drive with the floppy-drive, it automatically deleted the cdrom entry from /etc/fstab (which is good) but did not create an entry for the floppy device in /etc/fstab (which is bad !). So I manually added an entry such as: /dev/fd0 /mnt/floppy auto noauto,user,sync 0 0 and tried to read a floppy but it failed to mount it with dmesg giving these errors: end_request: I/O error, dev 02:00 (floppy), sector 0 end_request: I/O error, dev 02:00 (floppy), sector 0 end_request: I/O error, dev 02:00 (floppy), sector 2 end_request: I/O error, dev 02:00 (floppy), sector 4 end_request: I/O error, dev 02:00 (floppy), sector 6 I have tried mounting a floppy as root and as non-root user and the problem is always there. I can't even create a boot floppy now !! Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Just try mounting a floppy (as root or non-root user) 2. 3. Actual Results: It will fail to mount a floppy Expected Results: Should mount the floppy just fine. Additional info:
I have a Digital laptop and have had the exact same problem.
Is this in any way connected to bug74080 & bug80949 ?
Not quite. In my case, the floppy was MS windows readable on the same laptop, which means it was definitely not ext2 formatted. Its also readable just fine on linux on other machines. Therefore, its not: - a problem of corrupt floppy disk - a problem of bad floppy drive - ext2 file system specific
The same problem is present in redhat 9 on the same laptop (IBM T22).
This bug seems to be rather old. A quick search on http://www.ask.com for "end_request: I/O error, dev 02:00 (floppy)" will reveal a multitude of reports, some dating back to 1996! The most disgraceful thing about this bug is that it hangs the whole system! Also, which is also very bad, it corrupts data on the floppy. For me it happens on a brand new machine running under RedHat 9. It is so annoying that I am seriously considering blowing the Linux partition away and going back to Windos.
This error; kernel: end_request: I/O error, dev 02:00 (floppy), sector 0 is happening to me using Redhat 9. Previously, I had Version 8.0 installed with no problems. A check of my device permissions shows; brw-rw---- 1 fs01 floppy 2, 0 Jan 30 2003 /dev/fd0 which is normal as far as I can tell.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
