[SOLVED] NTFS drive recognized as vfat

konzo · 01-05-2010, 04:08 AM

I have NTFS partition which is recognized as vfat in /etc/fstab. Here is
my /etc/fstab:

Code:

/dev/sda3        swap             swap        defaults         0   0
/dev/sda4        /                ext3        defaults         1   1
/dev/sda1        /c               ntfs-3g     umask=000        1   0
/dev/sda5        /d               vfat        defaults         1   0
/dev/sdb5        /freeagent       ntfs-3g     umask=777        1   0
/dev/sdc1        /flashcard       vfat        defaults         1   0
#/dev/cdrom      /mnt/cdrom       auto        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
tmpfs            /dev/shm         tmpfs       defaults         0   0

If I try to change "defaults" with "umask=777" will it work? I want to make this partition writable. Why it is vfat, but no ntfs-3g as other NTFS partitions?

fdisk -l give this:

I edit fstab. The new one is:

Code:

/dev/sda3        swap             swap        defaults         0   0
/dev/sda4        /                ext3        defaults         1   1
/dev/sda1        /c               ntfs-3g     umask=000        1   0
/dev/sda5        /d               vfat        rw,user          1   0
/dev/sdb5        /freeagent       ntfs-3g     rw,user          1   0
#/dev/sdc1       /flashcard       vfat        defaults         1   0
#/dev/cdrom      /mnt/cdrom       auto        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
tmpfs            /dev/shm         tmpfs       defaults         0   0

It gives no errors, but only sda1 is read-writeble. Can't browse sda5 and sdb5.

Are you talking about /dev/sda5 ? It is a fat partition. Hence vfat. To make it writable use rw,user

konzo · 01-05-2010, 05:01 AM

Yes its about /dev/sda5, but /dev/sdb5 is also not browseble. I am sure that sda5 is ntfs, but in fstab is vfat. Can be any error in fstab?

konzo · 01-05-2010, 05:08 AM

ls -la result:

Code:

d?????????   ? ?    ?        ?                ? freeagent

jschiwal · 01-05-2010, 05:39 AM

Examine the filesystems with "sudo file -s". It's best not to make assumptions. The fdisk -l listing will list what the partition is identifies as (a byte in the partition table) but not how the filesystem was formatted.

How did the fstab entry for /dev/sda5 get created?

konzo · 01-05-2010, 05:51 AM

This is the output of file -s command:

file /dev/sda5 -s

Code:

/dev/sda5: x86 boot sector, code offset 0x52, OEM-ID "NTFS    ", sectors/cluster 8, reserved sectors 0, Media descriptor 0xf8, heads 255, hidden sectors 63, dos < 4.0 BootSector (0x80)

I did not understand what type my partition is.

The /dev/sda5 was created automatically when installing linux. I edit only from defaults to rw,user.

konzo · 01-07-2010, 10:31 AM

Maybe I didn't describe my problem correct. Before I was not able to browse my external drive and my "d" partition. After restarting external drive is readable, I can browse it and write to it.

Problem is that I can't view my "d:" partition. I don't change anything from last time. Can anyone help?

When type dmesg | tail get that on screen:

Code:

sdc: p1 size 7853056 limited to end of disk
sd 6:0:0:0: [sdc] Attached SCSI removable disk
sd 6:0:0:0: Attached scsi generic sg3 type 0

FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sda5.
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sda5.

I found on google that b in ID mean that my fat32 is without LBA.

Hope that will help someone to help me back

Edit: I cant run fsck /dev/sda5 or fsck /dev/sda2
theese errors appear:

Code:

sck /dev/sda5
fsck 1.41.8 (11-July-2009)
fsck: fsck.vfat: not found
fsck: Error 2 while executing fsck.vfat for /dev/sda5

Code:

fsck /dev/sda2
fsck 1.41.8 (11-July-2009)
e2fsck 1.41.8 (11-July-2009)
/sbin/e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda2
Could this be a zero-length partition?

up

any help or suggestion?

Looks like it actually is NTFS - try this

Code:

sudo umount /d
sudo mount -t ntfs-3g -o rw,user /d

If that works, update fstab.

markush · 01-08-2010, 06:06 PM

Hello together,

I'd suggest to use fdisk and look which ID the partition has. I once had the issue that a partition was not properly recognized as ext3 but vfat. In this case I had formatted a formerly fat partition with ext3 but did not change the ID in the partitiontable.

konzo · 01-10-2010, 09:50 AM

Thanks sygOO. I don't know why but when I mount it as root it is ok. In fstab I change vfat with ntfs but with no success. Anyway I will mount as root whan use it.

syg00 · 01-10-2010, 05:15 PM

Try changing the partition id - from fdisk it's

Code:

sudo fdisk /dev/sda
m  <- gets a command list; just interest
t  <- change type
5  <- partition number
7  <- hex code for NTFS
w  <- update the partition table
q  <- quit
