External Hard Drive / sleeping

Tue Nov 27, 2012 12:59 am

I'm having an issue with my 3TB external hard drive disconnecting from the pi when not in use. Here's the scenario. Everything works fine, I can:

- Turn on my pi and mount the external hard drive using the 'mount' command.
- Download files to the hard drive with no issues.
- Watch videos off the hard drive with no issues.

I can use the hard drive with no issues for hours. However, if I leave or let the pi go inactive for more then, say, 30 min or so, the hard drive disconnects from the mount point and I get I/O errors accross the board and then have to umount and re-mount the disk to use it. Usually the disk has re-connected to a different path.

Code: Select all

/dev/sda1  to   /dev/sdb1
At first I thought it was power issues. But the drive itself has it's own power adapter and I'm plugging the USB drive into a powered USB hub to first then into the pi. There are no other USB devices connected.

Is this caused by the pi or the drive itself going into a "sleep" mode or something?

I also encount this kind of problem: my USB hard drive (self powered) is unavailable after few minutes if I'm not using it.

It looks indeed like a sort of "auto sleep" mode.

Any news?
