It depends: I'm using a similar drive. These drives are very prone to
turn themselves off into power saving mode or similar / lose
interrupts. At this point they remount read only / with directories
with no permissions.
A colleague used Google to find that the problem may be with SCSI
emulation - if you echo 1 > allow_restart in
/sys/block/sd*/device/scsi_disk: the problem may go away.
Known problem :(

Thanks for the ideas. I did a more in-depth Google search and came
across this:
http://ubuntuforums.org/showthread.php?t=494673
So far so good, but the proof will really be to leave it for a couple of
hours and then see.
Holding thumbs!

FreeAgent USB HDD
Hi all
Yesterday, I bought a 500GB Seagate FreeAgent (external) USB hard drive.
I plugged it in, downloaded the necessary ntfs-3g driver and all was
fine. Today I plug it in and my Lenny system can't find it at all. There
is nothing loaded on media and it seems that as far as my system is
concerned, it has ceased to exist.
How can I load this manually and how can I prevent this from happening
again? I am not even sure how to debug this, so any help on that score
would be useful too. It has something like 100GB of data on it from
yesterday which I am extremely loathe to lose.
Thanks for any assistance.
Andy

Thanks for that info Joseph - I wasn't aware that they did that.
Certainly doesn't mention that in the booklet that came with the drive.
Interestingly enough however, I can click the desktop icon, and the file
will open up suggesting that from my machine's perspective, the drive is
still mounted and operational. Or have I completely misunderstood how
these things work?
Cheers
Andy
