USB Compact flash card reader hotplug creates /dev/sda but no /dev/sda1 -Mandrake 9.1


Hie!

I've just bought a USB CF card reader. It works fine with the knoppix 3..2 (I have stored files on it) but not with the Mandrake 9.1.

uname -r : 2.4.21-0.18mdk.

Although, under Mandrake 9.1, the device is recognized as a USB Mass Storage Device as you can see below in the /var/log/messages file :

Aug 11 09:43:18 pingouin /etc/hotplug/scsi.agent: sd_mod allready loaded


So, as the capacity of the card (it's a 256Mo) connot be read, a /dev/sda is created when I plug the card reader, but no /dev/sda1... => no icon appears on the desktop

Any idea ?

probably your card is not partitioned at all ?

try "fdisk -l /dev/sda" and check if there is a partition table on your CF card

Thank you for your help, but I've found the answer in an other thread... The problem came from the fact that I've got a 6 in 1 reader, and such a device is devided into 4 "sub" readers (CF/MD, SmartMedia, MemoryStick and SecureDigital) viewed as scsi devices /dev/sda, sdb, sdc and sdd. But the kernel viewed only the first one (/dev/sda), and it wasn't the CF reader. To make it work, the kernel must be compiled with the option "Probe all LUNs on each SCSI device" in "SCSI support" (CONFIG_SCSI_MULTI_LUN=y).

This was not the case with the kernel of the Mandrake 9.1... so I had to recompile the kernel... and now it works fine...
