external hard disk Automatically Unmounting - maxtor one touch 4

[nrgflux]

Description: Ubuntu 9.10
Release: 9.10

External hard drive (a Maxtor OneTouch 4 Plus in my case) unmounts automatically when spinning down.
The HD effectively disappears from the system.

The drive functions normal in 9.04

Same with my Maxtor and a western digital ext HD. Ubuntu really needs a patch or a small program for dummies like me to set drive spindowns to not unmount ext HDs makes backing up near to impossible and I don't think just not buying these 2 major barnd ext HDs is the answer if Ubuntu wants to keep users from returning to windows, thanks

Hello
Is this problem present with the latest updated Karmic's, Lucid's or Maverick's packages?
Thanks in advance
Fabio

Hello
Have you tried to run a s.m.a.r.t. test of the drive with disk manager
Thanks
Fabio

No I haven't how is that done? And this is a well docvumented problem of Seagate and Maxtor driuve that powert down to save energy and this causes an unmount in Linux. Mine both will power down if even a few seconds pause happens.

I have the same problem in Maverick. My external hard disk is a Packard Bell. After a variable time 3-8 hours the HD is unmounted.
Is there any workaround waiting for the fix?
