HDD gets mounted and then unmounted again
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. |

RE: HDD gets mounted and then unmounted again
It sounds like there is a power issue with the HDD.
You haven't explained your configuration in "Please read before you post" so I will have to guess. How is it powered? If not powered then you need to use a powered hub. If it has it's own power supply, then please post the output from dmesg via pastebin.com. RPi A,B and + only supply 100ma to the USB port. RPi2 only gives about 400ma. A standard HDD requires around 490ma. Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.

It is connected to the RaspberryPi via two USB plugs (one cable that branches off into two USB plugs at the end). I cannot conceive how this should be a problem as the HDD had been used for many months before this issue came up. |

Do you need more information? As I'm not a Linux crack I don't know how to get the "output from dmesg".

RE: HDD gets mounted and then unmounted again
Hi,
I bought myself a new power supply with 2500 mA (the old one had 1200 mA). Now it works again! Thanks to you all! |
