I have a 500 GB Maxtor OneTouch 4 external USB powered mini drive
that is missfunctioning. Even though I mount it rw, it apparently
resets itself to ro and I have also noticed that when the drive is
idle for a while it starts to missfunction, but not when I keep it
busy transferring data
~
Most problems with such drives are with the interface to the drives
and not the drives themselves, so I need to know if I could save the
drive (and of course the data) by taking the actual drive out and
putting it in another encasement
~
How can you tell exactly which model number you have? Maxtor tells me

~
it should be a STM90####OTA3E1-RK but there are 11 options there and
it is impossible to see exactly what mine is
~
I was having these problems under Windows too, I just used Linux
trying to troubleshoot/get more info out of it. This is what I
sometimes get when I try to list my drive

I followed the seagate link you provided. It appears that
your 500gB drive is STM905003OTA3E1-RK.

The Seagate site offers the Seatools diagnostic package as a
download. This should tell you a lot about what is wrong
and perhaps even fix it!

You newsgroup posting will reach more readers if you don't
post from google groups. Many newsgroup users block posts
from google because it is a major path for spam. We don't
want to know about cheap sneakers.

This helps my Seagate external drive.
