I am new to linux and to this forum. Just wondering if anyone knows of any possible explanation for my problem:

I am trying to mount a Iomega ZIP 100 parallel port drive on a system running Red Hat 6.2.

I logged in as root, ran the following commands:
/sbin/modprobe ppa (heard the noisy response on the zip drive with a zip disk inserted)
/sbin/modprobe vfat

mkdir /mnt/zip

added following line to /etc/fstab

/dev/sda4 /mnt/zip vfat noauto,user 0 0

then after I issued the following command:

mount -t vfat /dev/sda4 /mnt/zip

the system just hangs. I don't even get another prompt.
I can close the window but when I try to halt the system, it will not shutdown. It seems to have trouble unmounting somethng.

Does anyone have an answer? Thanks!

what kernel are you running?, I hope you are not running the stock kernel that comes with RH6.2!!
If that is the case, the best thing would be to download the latest kernel, 2.4.19, configure it and enable Devices such as Zip drives to be able to access through parallel port. compile the kernel, install it, and then boot it. It should work just fine after you do this.,
cheers.
