2.6.25: usb-storage unknown partition table issue

Hi,

i have a 8GB usb pen with several problem due to partition table.

if i create a primary one with fdisk, then format it works ok.
then i umount it, unplug, replug, no more partition detected.

I formatted it on Windows (same machine) and this some stress test, but
it's brand new and it works.
The partition and the free space is correctly seen by qtparted and
parted, but in the dmesg i see:

Initializing USB Mass Storage driver...
scsi10 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.

sd 10:0:0:0: [sdc] Assuming drive cache: write through
sdc: unknown partition table
sd 10:0:0:0: [sdc] Attached SCSI removable disk

This makes the partition unasable in my linux 2.6.25 (vanilla) system.
Another 1gb usbpen works perfectly.

Bus 004 Device 001: ID 1d6b:0001
Bus 005 Device 001: ID 1d6b:0001
Bus 002 Device 001: ID 1d6b:0001
Bus 003 Device 001: ID 1d6b:0001
Bus 001 Device 002: ID 1307:0165 Transcend Information, Inc.
Bus 001 Device 001: ID 1d6b:0002

Anything i can try?
It looks a scsi issue. And it's the first time i see the Mode Sense set
to 0 for any usb storage device.

Looks like you did not enable the partition type "PC BIOS".

Type "make menuconfig" and make sure you enabled it on:

Partition types / Advanced partition / pc bios (ms dos partition tables)

Discard any SCSI issue, indeed I am almost sure you can do a "cp
/dev/sda /dev/null" with no problem (showing that your SCSI driver is
working properly).

Yours, Abel.

Hi Abel/All,

it doesn't work at all. Actually even other pen i have were formatted in
windows and they work ok.

And, as said, parted reconize it. now i destroyed and created again with
parted, but on windows it works, on linux not.

What else to try?

Patrizio

Can you supply me your .config file? I am sure it is just a matter of
enabling the correct option there.

Yours, Abel.
