Need help with script

[SLG]

I have a problem with my USB drives spinning down so I wrote a simple script that would 'touch' a file and copy it every minute to keep the drives alive. Now I want to take it one step further. I would like the script to check if the drive is mounted, if not try to mount it, then write to it and if it doesn't work send me an email. ;-)
It has been 10+ yrs since I wrote a complicated shell script and I need a little help.
Thanks in advance!

This is a ksh script on top of my head as i don't have a machine to test it

df -h | grep usb_mount
if [[ $? -ne 0 ]]
then
mount /usb_mount
touch /usb_mount/testing
if [[ $? -ne 0 ]]
then
cat Drive was dismounted > /tmp/temp.out
mail -s "Drive dismounted" "your_email@domain" < /tmp/temp.out
fi
fi

Great, I'll try it and let you know.

Have you tried hdparm or sdparm to disable the spin down?
I can't try it at the moment, but you should be able to change the behaviour.

Yes. The spin down is hard coded into the drive so sdparm does not work. >:-<
I've been struggling with this for a few months now and I'm about the scrap the whole drive.
About every few days the USB drive will 'hiccup' and starts throwing I/O errors. I have my touch scripting running as well as the script above but it doesn't seem to matter.
