I have a Pi B2 which I am using as a home server running Transmission, Sabnzbd, Couch Potato & SickBeard. To the PI I have attached an old internal hard disk made external (80 GB). This is where everything is downloaded to.
The problem is that at random intervals my HD head crashes. All off a sudden I can hear the head of the HD clicking. At that point I either have to reboot the Pi or have to remove and reconnect the drive. Sometimes it fails every few minutes; sometimes it runs for 2-3 days before failing.
Currently I am using a always running shell script that tries to unmount and mount the drive whenever it becomes inaccessible. But it still fails.
From this I guess that internal hard disk probably needs more power. My reason to believe this is that when I tried to make it external the vendor gave me a casing with a Y cable.
Will the problem solve if I replace the HD with an external HD of a similar size? I have seen external HDD with 250GB and all coming with just a single USB cable. Please advice.
