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.

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:<numbers> the problem may go away.

Known problem :(

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.

Andrew (& others)

Thanks for the ideas. I did a more in-depth Google search and came across this:

So far so good, but the proof will really be to leave it for a couple of hours and then see.

Holding thumbs!

Andy
