[SOLVED] HDD gets mounted and then unmounted again

[goodappetite]

Hi there!

The problem in short:
My external HDD gets mounted, and then unmounted again shortly thereafter (a few seconds). I know that because of the messages "device successfully mounted" and "device successfully unmounted" or something like that.

Background:
Recently, my RaspberryPi didn't show the content of my external HDD anymore. I unplugged the drive and tested it with my laptop. The drive is formatted with ext3 (I think? some "ext" in any case), and I managed to read and copy the content. So the drive looks okay. Then I updated Xbian to its newest stable version - still the same problem. After that, I tried the newest unstable version - still the same result. Though I changed Xbian versions, I didn't delete the configuration files / customization.

Could the reason be a corrupted configuration file? Or is it something else?

Thanks.
