Automatically dismount of USB drives

Hello,

when I have mounted my USB hard disc with Dolphin, it gets often dismounted automatically if I only browse through the file system. During transfer of files this doesn’t happen.
Is there an automatically dismount activated? How can I deactivate it? What else could be the problem?

Thanks
Albert

I have an external 500GB Hard Drive that I use for Backing up my important files to. I cannot run my script file until I go into Dolphin and click on the external hard drive…this is because the drive goes into power saving mode, not because it is being un-mounted. Could this be your problem?

Cheers!:slight_smile:

Quite a common ‘feature’ among usb drives. I also wonder if this is what the OP means?

I have seen this type of ‘problem’ reported from time to time, and it only seems to affect certain models (especially usb-powered devices). I note you didn’t supply this info. I guess you could keep it awake by polling it with a cron job and simple script if necessary?

This Ubuntu post seems to mention a possible solution is to remove the USB-2.0 (ehci-hcd) driver, resulting in slower r/w activity, but without the problem. (I’m skeptical that this would work though).

Next time the drive becomes inactive (unmounted), maybe have a look at dmesg|tail output for any clues. Does it still stay detected at least? The command ‘fdisk -l’ will show this.
