Have you tried using /dev/sda4 instead of /dev/sda1 ?

Wrong tree. :)

1) I needed to load usb-uhci. This will take care of the major/minor problem.

2) I needed to define my USB device (SDDR09) in the kernel config files.

3) It takes about 1 min to mount this USB device.

4) The kernel driver has a memory leak, and will only allow a certain
amount of data transfer before making the kernel panic.

I have a Sandisk Imagemate SDDR09 photo card reader I am trying to get
working under Linux 2.4.2.

The device is detected properly:

I am trying to follow

The sd_mod module is loaded by the mount command, probably in search
of some scsi disk.

I am at a loss to figure out how to do this. Help, please?

1. Wrong major or minor number mounting /dev/scd1

Dear Linux-experts,

Yesterday I have installed my CD-RW (Philips CDD-3610).
I have burned 1 CD-RW succesfully. However, after a reboot
I was unable to mount my /dev/scd1 anymore:

mount: /dev/scd1 wrong major or minor number.

Strangely enough, I can still mount /dev/scd0 (my 'old' CD-ROM),
so my SCSI-emulation works. What can I do? What might
be the cause of this?

Thanks in advance,

Zeger.

(PS: 'cdrecord -scanbus' shows merely 1 device now,
my CD-ROM, and 'dmesg' shows all kind of strange messages
concerning my CDR.  /dev/hdd is recognized properly as a
6x2x2 CD-Writer during first part of boot sequence).
