Re: Sandisk sddr-75 CF/SM usb reader problems
OK, here's what I notice: in /dev, your /dev/sd* device entries are
correctly set up with block major device number 8, as is the case for
the first (I think) 33 scsi disk devices.
The output of /proc/devices, however, does not show that you have a
block major device 8 entry, which should show the "sd" driver.
My system's output for the same two commands does indeed show block
major 8 as a device in /proc/devices, with sd as the driver - so I would
surmise that this is your problem and why the devices don't seem to
exist. When you try to mount /dev/sda1, the kernel should be looking
for driver registered to handled block major 8, but there isn't one.
A harder question is WHY you don't have one. On my system, it appears
that scsi disk support is built into the kernel - because I haven't
loaded sd.o as a module and no such module appears in
/lib/modules/2.4.18.../kernel/drivers/scsi.
You need to verify that on your system, with whatever kernel you are
running, that either a) scsi disk support is compiled into the kernel,
or b) if it is built as a module, you are loading the module (eg by
putting this entry into /etc/modules or by whatever other mechanism you
prefer.
While the kernel does dynamically locate and load some modules as needed
based on system calls, I don't know if the scsi subsystem or mount
subsystem does that for the scsi disk drivers; maybe someone on the list
has delved into that aspect of the kernel code and can help here. My
guess would be "no".
Hope this helps.
