USB stick being dismounted

(1/2) > >>

thane:
I'm running TC x86_64 version 15 on a lenovo X201 laptop, booting off a USB stick (no hard drive). Doing this pretty much daily. Every now and then (say once a month) when I check apps for updates before I shut down I find that the USB stick has been dismounted and the TCE directory is not writeable.

99% sure this is some sort of hardware issue specific to my setup (e.g. flaky connector or USB stick) but just wondering if anyone else ever encountered this. Nothing I can't live with -- I mainly use this box for websurfing when I want a screen that's bigger than my phone's.

CNK:
If there's a hardware or filesystem problem that causes an error, the default in TC is "remount-ro" (which I've seen before with faulty drives and USB connections), so the filesystem becomes read-only but is still mounted. You can change this behaviour in /etc/fstab or with the mount command so the errors are ignored ("errors=continue"), but I wouldn't recommend it since the filesystem might get so messed up that TC won't boot anymore (although that might also happen eventually with the default setting).

curaga:
Check dmesg when that happens.

patrikg:
Maybe powersave mode, check bios for powersave to save battery-power it's shutdowns the usb ports.

Belated thanks for the replies. The issue hasn't reoccurred since I posted but if/when it does I'll try the suggestions.
