External USB drive mounting/unmounting
 

I would like to know if it is possible to mount/umount automatically when I power on/off the external device. I have to mount four partitions (3 fat32 and 1 ntfs) if i have to do it manually.

I put the entries in fstab but I have to mount manually whenever I forget to power on the external device. Also I'm not sure if it is ok if I power off the external device before shutting down the system (It gives errors while unmountinf the file systems).

Any suggestions are welcome

could look at howto library for article about automount by rahul sundaram
have it myself but can't figure it out yet.
if you know sooner than me let me know otherwise will tell you.
