Welcome to LQ!
You'll have to get root to do some sysadmin for you.
Easiest is to give you a mount point, such as /mnt/JetFlash or if you
have your own user directory, perhaps /home/<username>/JetFlash
and then he's got to either give you something in /etc/fstab such as
Code:
/dev/sda1 /mnt/JetFlash vfat user,uid=<your_user's_number>,unhide,rw,noauto 0 0
so that you can mount and read/write the device. But if it won't be mounted
on /dev/sda1 every time, he may have to use something like udev and put
rules that know it's your flash drive. If you're the only one, and your drive
is the only one, I think the above example should work fine.
He could also setup rules for you using sudo. Read
man sudo
man sudoers
for more information.
