Thanks for all the info, especially info on the spring loaded access door.
The vacuum venting makes sense but I'm still perplexed as to how the
read/write head gets access to the magnetic surface. As I stated in my
original posting, 4 of them seem to have broken off. Do you think it's best
to open the rest of the broken ones up (in a very clean dust free area) and
remove them or leave them in there flopping around risking damage during
transit? They are pretty easy to open up.I was thinking of carefully taping
shut the opening with masking tape and a small patch of plastic.
Also, they have been claimed already, sorry. A portion will be donated to
CHM.
