Can you send me the first 64k of the device? i.e.: sudo dd if=/dev/sdb5 of=/tmp/jfs.img bs=64k count=1
And then upload /tmp/jfs.img I have no doubt that moving the JFS-related entry before the VFAT entry will solve the problem, but the probe_fat_nomagic() does a lot of tests before concluding that the filesystem is VFAT. This leads me to believe that /dev/sdb5 was previously formatted as VFAT, and the JFS mkfs didn't do enough to eradicate the traces of the old VFAT partition. The problem is that there is a much weaker test for JFS, so this could lead to false positives in the other direction. (i.e., a JFS filesystem which is then formatted to be a VFAT partition.) So I'd like to get a copy of the beginning of the filesystem to see if there's a better fix. My guess is the other problem is that mkfs.jfs needs to do a better job wiping out the first few kilobytes of the image to prevent this kind of false positive. -- blkid library detects JFS partition as FAT32 https://bugs.launchpad.net/bugs/255255 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
