Please help me. I've got a Spectre 128 and a Translator One. I have been
unable to format a Mac disk with my drives. I called Data Pacific and
they said if my drives are more than 1% fast the format will not work.
My drives checked out at 304.5 rpm. My question is:can you adjust the
speed on a (green lighted)TDK drive? I've looked at the board on the drive
drive itself and found one adjustable pot. Is this the speed control?
I'm not sure of the exact number on the drive, seemed like it was TDK14
or something like that. Anyone out there done this? successfully??
Any replies would be greatly appreciated.

If your drive is running between about 295 and 308-310 RPM you should be able to format a disk in Mac mode. Can the Translator read and write to the disk? If it can't write to a Mac disk then the problem is probably not the speed. Some drives just will not work with the Translator due to high or low pass filters that prevent the Mac data from getting to/from the disk. Some 3.5" drives have a drive speed adjustment, most do not. I don't know if TDK drives have one or not. It can't hurt to try the changing the pot, if it doesn't change the speed just make sure you change it back to the way it was. Dan Moore AT&T Bell Labs Denver dlm@druhi.ATT.COM dlm@druwy.ATT.COM

Warning: the ubiquitous speed checker by Curry (I believe - anyway San Leandro ...) shows 303 rpm when the drive is actually spinning at 300 rpm (according to previous reports). If you used this utility to check speed then you are within spec.
