mount external firewire drive udf formatted

Hello all,

I seem to have goofed up a bit and i was hoping that you guys might have some advice for me.

i have an external firewire drive that i wanted to share between my mac and linux box. without thinking it out too thoroughly. I formatted the drive in mac os x with the unix setting which is udf. so i now have an entire block device that is udf formatted. I cannot seem to mount the drive on my linux box. i get the standard error:

mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems

I have fixed the fstab and used the mount command correctly

mount -t udf /dev/sda /mnt/fire1

the problem i have read may ly in the fact that the udf versions are incompatible(ie mac 1.5, linux 2.0).

I basically need to get the data off of the drive, and then i will reformat to ext3 format. does anyone know of a system on which i may mount the drive? the obvious answer is the mac. there is however a problem with that in that the mac will create but does not like an entire block device that is udf formatted. It will write to the drive but if I try to copy data from the drive back to the mac, I get a kernel panic.

can anyone help get this mounted on my linux box or any other machine for that matter?

thanks for the help in advance.

cheers -

a little more info:

from /var/log/warn

Jan 17 12:13:24 bravo5 kernel: Vendor: WDC WD16 Model: 00BB-00DWA0 Rev: 15.0
Jan 17 12:13:24 bravo5 kernel: Type: Direct-Access ANSI SCSI revision: 06
Jan 17 12:13:24 bravo5 kernel: sg_attach: dev14=(21:14)
Jan 17 12:13:24 bravo5 kernel: Attached scsi disk sda at scsi1, channel 0, id 0, lun 0
Jan 17 12:13:24 bravo5 kernel: SCSI device sda: 312581808 512-byte hdwr sectors (160042 MB)
Jan 17 12:26:23 bravo5 kernel: UDF-fs: No partition found (1)

and from

fdisk -l

Disk /dev/sda: 255 heads, 63 sectors, 19457 cylinders
Units = cylinders of 16065 * 512 bytes

Disk /dev/sda doesn't contain a valid partition table

so the question is if the partition table is fixed will i be able to mount in linux? and if so, how do i fix it? i am running suse 8.1.

thanks again -

the third time is the charm, eh. well i had the info a little skewed, so here is an update

i believe i was wrong and the format is actually ufs rather than udf. but the partition table i believe is screwed up, ie.

bravo5:/xtal/green # fdisk -l /dev/sda

Disk /dev/sda: 255 heads, 63 sectors, 19457 cylinders
Units = cylinders of 16065 * 512 bytes

Disk /dev/sda doesn't contain a valid partition table

however if i used parted then i get this info:

bravo5:/xtal/green # parted
GNU Parted 1.6.3

Using /dev/sda
Information: The operating system thinks the geometry on /dev/sda is
19457/255/63. Therefore, cylinder 1024 ends at 8032.499M.
(parted) print
Disk geometry for /dev/sda: 0.000-152627.835 megabytes

4 0.086 0.113 Macintosh type=Apple_Driver_ATA

8 0.641 0.890 Patch Partition type=Apple_Patches
9 0.891 152627.832 Untitled type=Apple_UFS


I think that i should be able to mount with this command:

modprobe ufs
mount -t ufs -o ufstype=openstep /dev/sda /mnt/fire1

but i still get :
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems

i think maybe as a result of the partition table.?.?

any suggestions? on the partition table which will allow me to mount on linux, without losing my data?

thanks - todd

First /dev/sda is the hole drive you have to use /dev/sda1 for your partition. You should also try to mount /dev/sda4 instead of /dev/sda1. I don't have a firewire drive but I have to use /dev/sda4 instead of /dev/sda1 with my old SCSI-Zip drive. Maybe this help. Good luck

Second hint: You have to compile partition table support for openstep in your kernel if you have make your partion with openstep!
