Fat32 Read Only?

natewlew · 06-22-2006, 08:08 PM

I used to write to my fat32 partition. Here is my fstab that I changed a few times trying to get it to work.

Quote:

/dev/hda7 /home/extra vfat rw,users,umask=000 0 0

Now I can't. I tried to delete a file as root and it say's I can't because its a Read Only Disc. Can anyone help?

/dev/hda7 /home/extra vfat ro,users,umask=000 0 0

Thanks for your help!

That didn't seem to work.

I ran dmesg:

Quote:

FAT: bogus logical sector size 0
UMSDOS: msdos_read_super failed, mount aborted.
FAT: bogus logical sector size 0
FAT: bogus logical sector size 0
Filesystem panic (dev 03:07).
FAT error
Directory 8: bad FAT

I guess somethings wrong with the drive.

FAT error should pretty much tell you it's a problem with the filesystem.

Running fsck.msdos on the partition might help. Or it might destroy the entire filesystem beyond repair.

I honestly am not sure how reliable that tool would be.

lmao

Can't be any worse than 'chkdisk' in Windows....

Windows did run a check on it and it seems to work fine, but its still no good in Slackware.

I put noauto on my fstab and added rw. I didn't get any errors when I booted. I mounted the drive and I can write to it.

So, something with the auto setting then....

At least, you've narrowed it down.
Can you post your new fstab? And have you done any 'upgrading' lately?
Windows or Slackware. Windows is notorious for changing things on the hdd without letting you know....
Usually, it messes with NTFS, but you never know....

My fstab:

Quote:

/dev/hda5 swap swap defaults 0 0
/dev/hda6 swap swap defaults 0 0
/dev/hda2 / reiserfs defaults 1 1
/dev/hda1 /home/ntfs ntfs ro,umask=0222,users 0 0
/dev/hda7 /home/extra vfat noauto,rw,users,umask=000 0 0
/dev/hdc /mnt/cdrom iso9660 udf,noauto,owner,ro 0 0
/dev/hdd /mnt/cdrom2 iso9660 udf,noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
none /sys sysfs defaults 0 0

No, I havn't done any upgrading.

I think the problem started when I tried to mount the partition on Solaris. When I mounted it on Solaris it said "/mnt/extra might be busy" , but it still mounted. I didn't think that was the cause but it might have been.
I have been getting errors when I booted slackware since I installed it about a week ago. Everything worked ok so I didn't worry about it. Now I'm not getting any. I guess turning off the auto did help

Is there anyway possible to backup the data on that partition, and remake a fresh fat32, then reinstall the data? Don't know why, but something is rattling around in the old database in my skull....

The problems with screwing with these OS's since '73. The dust is terrible in there.

And don't underestimate the possibility of a MS virus on the superblock of that partition....

natewlew · 06-23-2006, 02:26 PM

Yes I could do that, but it seems to be working ok.

The only files that I have on there are pictures and music that I have backed up.
