I have a Panasonic HS2 that came up with the dreaded U99 error. I was reading a post that rtjoby wrote reguarding the E85H with the U99 error, that you could replace the hard drive and that would fix the error. I tried replacing the hard drive in my model but without sucess. Is there another way to rid of this problem on the HS2? Is there anyway of recovering the hard drive on a pc? I tried booting it through a usb2 external case, i went into computer mangement on windows xp, it picked it up but wouldnt allow me access, is there a trick or some software to get access to it? Thanks.
