HELP, I have two Wallstreets and everytime I try to upgrade the HD it just come up with a "disk" as though there is no HD in the comptuer. I am have tried a 30 GIG not apple drive in it, which is now running fine in a newer powerbook. I have tried a 30 gig from Apple with the same results (this one has the 8 gig partition for OSX) and a 10 gig from that newer power book.
The only thing I can think of is that it is not getting enought power to the drive, it makes a "breathing" sound from the drive like it is trying to spin. I noticed that the voltage on the old drives was 5V .500a and the new ones are 5V .7a and 5V 1.0a
Thanks and God Bless
