usb disk is "lost" after some time

[v_andal]

I use USB disk for storing torrent files. As result quite often I leave my system running over night. And quite often I find it in the morning with report that there was bus error while accessing disk, and the disk would look like it was disconnected. First I thought, that this is disk problem. So I've bought another one, from different manufacturer. The story repeated itself with the new disk.

It looks like during the night the provider drops my connection to internet and the torrents program becomes idle. During this time the USB disk gets "disconnected" (some idle-timeout?) and when the program attempts to use it again later it gets the bus error. Now I've created little script that writes small file once per minute on the disk and the problems are gone. At least last few days the system worked without complains.

Is this a "feature"? If yes, then how can I tune the system so, that USB disk does not get lost when idle.

[richard.scott]

its not a feature that I've found on my usb disks.
are you using an automounter or perhaps its something running with your desktop that's automatically disconnecting the device after a period of time?

[v_andal]

No. I don't use automounter of any kind. I don't have desktop running neither. It's pure VT system without X. But I mount the disk with option user.

Look carefully at the dmesg output and /var/log/messages, if there's any hardware issue or a driver problem in your kernel then you should be able to see something in there.

[v_andal]

I was wrong. After few days the crash happened again. So it has nothing to do with timeouts. Here's what I have in /var/log/messages. Sorry, it's a bit long.

The last time when the script was able to write something to disk was at 02:39:21.

Maybe my USB controller is defect? I'll try to create the same setup on another computer. Though it shall take time.

It could be the usb controller, the disk, or a bug in a kernel driver (unlikely for such common hardware, but you can test another kernel version just in case).

If the disk is a regular disk on an external usb case you can always try to open that case and plug the disk directly using an IDE or SATA wire and see if that works.

I had a similiar problem and solved it:

Well. What is this STANDBY anyway? Does it turn off the disk automatically after some time? Then why the problem appears from time to time? I attach the disk every evening, but the crash happens once in 3-5 days.

Anyway, I've tried your command and it failed to work. I got an error

In your case the HD is also always active, right? Not 10min where it can go into standby?

This solved the problem for me, I have 2 external drives, one is western digital and the other seagate, the seagate removes itself completly from the system when it goes into standby.

So turning of standby solved the problem.

Not sure how to do it on your drive.
