[Bug 235520] New: Magneto-optical drive (MO) loses VFAT files
https://bugzilla.novell.com/show_bug.cgi?id=235520 Summary: Magneto-optical drive (MO) loses VFAT files Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: abrahams@acm.org QAContact: qa@suse.de I have a Fujitsu MCJ3230SS 2.3GB magneto-optical drive. My computer is dual-booting with Windows XP. I formatted the entire drive (/dev/sda) as VFAT, or FAT32 under Windows. Until recently the files on the drive could be viewed either under Windows or Linux; there were no problems. But now the drive shows up under Linux as empty, even though the files are there under Windows. I tried reformatting under Windows and replacing the files, but they still are not visible under Linux. I'm pretty sure that the problem started some time after I installed OpenSuSE 10.2 (as an upgrade), but I'm not sure whether it started right after the installation or after some later update. If I insert a file on the drive under Linux, it stays around and is visible under Windows -- but not, as I explained, vice versa. I also tried reformatting the drive under Linux using mkfs.vfat -I /dev/sda. That rendered the drive unreadable under Linux -- but did not affect how it appeared to Windows. The command df -m shows the drive to be about 2/3 full. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Also, do you have any other removable media, like a USB stick you can try to reproduce with? I'd like to try to narrow down where the problem is. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=235520 ------- Comment #3 from abrahams@acm.org 2007-01-17 18:40 MST ------- Because of a screwup on my part, the Windows output in my previous comment is incorrect; I was accessing the wrong drive. I also did some more experiments. I have two MO disks: 1. Disk #1 is readable on neither system and cannot be formatted on either system. The attempt to format it under Linux is shown in the previous comment. Windows will format it using a full FAT32 format but then can't read it. 2. Disk #2 is an older disk. It can be read under Windows but not under Linux, where it indicates a bad superblock. The format of that one vfat/FAT32. Now here's where it gets even more interesting. If I do a quick FAT32 format under Windows, the resulting disk can be read on either system. Not true for a full FAT32 format, though. All this may be confusing -- but the one clear indicator of a bug is that mkfs.vfat will exit successfully but the resulting disk has a bad superblock. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
