Most of the PDD design I think is pretty robust - physically at least. Things I would check off the top of my head:
- Is the belt still in place? - Does it still power up (PSU board has connector that could shift loose) - Does disk still insert / eject smoothly? One non-obvious thing I've seen on a couple of PDDs now is this: There is a metal tab on the top of the frame that lifts the felt pressure-pad off the disk cookie during eject. This tab was physically bent on 2 of the drives I've seen, preventing the felt from making contact. The result was that the cookie was not pressed firmly against the drive head and the disk was not read properly. Bending this tab is very touchy as the felt needs to raise up quickly enough to clear the disk shell on eject, but still lower fully to press the cookie to the head. Good luck! -Josh On Wed, Oct 7, 2020 at 12:40 PM Francois Gurin <franc...@gurin.org> wrote: > Reaching out to the list for advice and help. > > I recently replaced the belt on my TPDD2 and was in the process of writing > to a test disk when the drive fell a few feet onto the carpeted floor. > There's no obvious physical damage, but as you can expect it's no longer > able to read or write to disks.
