Subject: 2.4 -ac zip ppa -- 'mount: /dev/sda4 is not a valid block device'

Hi there,

Mounting a ppa zip drive:

2.4.21-rc5-ac2 and redhat 2.4.20-13.9 report sda4 as "not a
valid block device" and do not mount the drive.

2.4.21-rc6 and redhat 2.4.20-9 kernels work fine.

As two of these kernels are stock redhat releases, I doubt
my .config file is relevant. My system has IDE HD & CDROM.

File '/etc/modules.conf' has no references to scsi or parport
modules and I manually load modules with script zip-mount:

#!/bin/sh
echo "zip-mount: load modules & mount zip drive..."
insmod scsi_mod
insmod sd_mod
insmod parport
insmod parport_pc
insmod ppa
mount /mnt/zip

Hi there,

A followup: kernel 2.4.21-rc6-ac1 also fails to recognise
the zip ppa /dev/sda4 as a block device.

Cheers,
Grant.

Maybe a stupid question, but I'm assuming you have this as a module.
Have you loaded the module before trying to access the device ?
