Okay, here's the problem:

I've been using an external zip drive (parallel port) for a few weeks now, and it's been working fine. Popped in a disk this morning, and I get the message "mount: special device /dev/sda4 does not exist". Checking in /dev, and sure enough, there's sda1-3, and 5-15, but no 4!

I've searched dmesg and /var/log/messages, NO clues there at all. The disk (I've tried several) is fine, works great on another system. Tried mknod, which says it's creating the device file, but then when I check, it's STILL not there.

Can someone PLEASE tell me how to fix this?

Cuddles,

/dev/sda4 is a partition on your first SCSI drive (parallel port ZIP may well look like that)
There is no reason for you to have 4 partions, or more. It looks like you have a static /dev, since yo have 15 partitions.

remake the node with makenod (See man makenod)

I've tried that Neddy. No joy. It CLAIMS it's making the device (I'm using udev, btw), but the device still isn't there!

/about to pull out my hair over this, or switch to a new distro...

Cuddles,

Are you using the udev tarball?
look in /etc/conf.d/rc ?

There is something wrong with your /dev management - unless your really have 15 partitions on /dev/sda.
That makes me think that udev (or devfs) have failed and the init scripts have reverted to a get you going static /dev/.

Watch the boot messages carefully. Right at the start is says
Mounting /dev for .... ?
So you get a warning about udev and devfs not being used ?

Poking udev is harmless - try udevstart
