Dear Colleague,

I'm wondering if one of you might have an insight into the following
Problem (if this is the wrong listserv to post, please forgive me and
point me to a better site):

I have an iomega jaz/SCZI drive hooked up to my Pentium III Redhat 7.1 
machine. I use this drive for nightly backups.

On boot I mount the drive on /mnt/jaz using the following 
command listed in the /etc/rc.local file:

mount /dev/sda4 /mnt/jaz

All of this works fine. When log in I can access /mnt/jaz 
just fine. The problem is, I can write to /mnt/jaz, but only 
once! Once I write to the drive, subsequent writes cause the following
error:

cp: cannot create regular file `/mnt/jaz/some_file`: Read-only file
system

Interestingly enough, these are the results for ls -l on / and /mnt 

drwxr-xr-x    5 root     root         4096 Jul 25 06:34 mnt

and
 
drwxr-xr-x    4 root     root        16384 Dec 31  1969 jaz
 
So as root, I should be able to read and write these directories just 
fine.
 
Just as interesting, if I manually umount the drive and mount it 
again, I can, once again, write the drive; but only once!!!
 
Now, I can certainly modify my backup script to first umount and mount 
the drive before copying the files, but that seems like the wrong
approach to solving this problem.

Any ideas?

RR 

p.s. Any idea why /mnt/jaz has a date of Dec 31, 1969 on it?
