I'm also interested in this fix since I got my travelstar DJSA-220
finally to work on a WALLSTREET! I remarked the same noisy click and
since the troubles I had with a dead toshiba I pay very much attention
to strange noises.

For those who have a wallstreet and a travelstar, here the link which
made my combination work.

I first thought I really have to buy a new Powerbook.

Only a notice, it may help some one.....

Cheers

Andreas
