Greetings!

I recommend going through the FAQ also, but the symptoms you are posting could very well point to a bad drive. Back to your original point, if there is any way you can back up your music & data onto your PC, I would recommend you do so as soon as possible (if you do not have a backup already).

When you see errors like that, do they always point to the same hard drive? That would narrow the problem down to one connector on the ribbon cable or one drive going bad. And because the errors you posted were for hda, that is your boot drive and will cause the player not to boot. (Had it been hdc going bad, you would have been able to boot, but had problems when trying to access data from that drive.)
