What about all us old time service guys who never took courses on using these new fangled screwdriver whatnots! We`ll have to go on welfare as well.

I have some that are 1" diameter and 1/4" thick, and I guarantee you that they'll give you a pinch you will not soon forget! They are also extremely difficult to seperate, once locked-together.

Torx Plus is different from Torx, and Torx Plus TR is different from either. -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net)

Nonsense. If it's clicking it means it does a rezero every time it retries a read operation. It does that on ECC errors and also on CRC errors on the interface. Neither is necessarily caused by a hardware failure. Bad power supply, overheated drive or bad data cable can cause this too. > I've had some luck placing the whole drive in the freezer for a couple hours > and then copying the important stuff off immediately but if that doesn't > work either pay the $ for professional recovery or throw away the drive > because I can guarantee you won't fix it by opening it. |
