seagate drive and i/o errors

[Littlefield, Tyler]

Hello all,
I have a quick question. When I do a ls on this drive and it's spun 
down, i get an i/o error. I'm curious if there's a way to write a module 
or do something to make the drive wake up when I do a r/w request on it? 
I've had an external and it never had this problem. I also know i could 
modify the scsi params to make it not sleep, but that doesn't work and 
that is not the best of ideas anyway. I like it sleeping, I don't even 
mind waiting for an LS. It's just hard to manage when i have to umount 
-l the directory, then figure out what sd* dev it's on.

care to describe the error?   i suspect it may be hardware error.
just post your dmesg after u plug in the hardware device.   perhaps do
a lsusb -vv and show us the details of the drive?

For automatically mounting filesystem, if u are on ubuntu:

https://help.ubuntu.com/community/Fstab

(just update the fstab file) is one option.

Alternatively is automount (and using autofs kernel module) is another
option.   If u are on linux kernel 3.1.0 (mine) the kernel module is
called autofs4, not sure what is the difference, but nevertheless just
do a "modprobe autofs" (not default loaded for me):
