 Posted: Fri Sep 24, 2004 1:33 am Post subject: bad superblock fat32 - can't mount |
 |
|
When I try to mount my fat32 hard drive, this is what I get.
| Code: | bash-2.05b# mount -t vfat /dev/hdc1 /mnt/music
mount: wrong fs type, bad option, bad superblock on /dev/hdc1, or too many mounted file systems |
fdisk tells me this:
| Code: | bash-2.05b# fdisk -l /dev/hdc1
Disk /dev/hdc1: 120.0 GB, 120031478784 bytes
255 heads, 63 sectors/track, 14592 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdc1p4 128454 128456 19911 0 Empty
Partition 4 does not end on cylinder boundary. |
I converted the partition from ntfs to fat32 with partition magick so that I would be able to write to it from linux while I move my files around and format everything with ext2 fs. I would just format, only problem is I need all the stuff on this drive. If I can just mount it, I can go on from there, but since I can't, anyone know of anything I can do. I tried a few things with the program parted, mostly just resizing. And dosfsck on the drive, but nothing is changing it. I am also using kernel 2.6.8.1-ck7, and I read something about fat32 not working with 2.6.8.1, is this true.
thanks |

| ok, I added codepage 437 to my kernel, and looked under the dos/fat/ntfs section and codepage is set to 437. But I still get the same error and dmesg still tells me the same thing. Any ideas? |

Not a problem. This seems to be a recurring problem with USB storage devices and the 2.6 kernels. Glad you got it fixed.

Thank you guys,
I fixed my problem.
The codepage was missing in my kernel config.
I've just load the default codepage cp437 as module and now it works fine.
I definitely love this forum...  |

i'm having this same problem. i get this when trying to mount the usb drive (after setting up the partition type as FAT32 (b) in fdisk and vfat file system with mkfs.vfat -F 32):
| Code: | mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems
|
and this in /var/log/messages:
| Code: | Unable to load NLS charset cp437
FAT: codepage cp437 not found |
..when i try to mount the usbdrive.
this is in my fstab:
| Code: | /dev/sda1 /mnt/usbstick vfat user,noauto,umask=002,gid=35,codepage=437 0 0
|
i have cp437 compiled as an option for the vfat module and the vfat module loaded. these modules are loaded.

Probably it doesn't matter here, but it's something everyone dual-booting should know. Windows like partitions to end on cylinder boundaries; linux (and possibly other systems) doesn't care. This can lead to fs corruption and data loss when manipulating Windows partitions with linux tools (yes, it also happened to me years ago). So, as bad as it's sounds, Partition Magic is a dual-booter's good friend.  |

That's exactly what I needed...thanks for posting that. They were pretty easy to find, but for anyone having trouble, they were under File Systems > Native Language Support.

@Serfurj,
could you edit your thread to break the line:
snd_pcm_oss,snd_mixer_oss,snd_emu10k1,snd_rawmidi,snd_pcm, snd_timer,snd_seq_device,snd_ac97_codec,snd_util_mem,snd_hwdep
its making the thread pretty unreadable.
Thx.

Ha! Brilliant.
I thought it was the code block that was fixing the width 
Anyway its a useful thread now I can read it better.
Thx
