It really is critical to know what the controller and BIOS }version are to know if this might be a problem. No, it's even worse than that. The ST506 has a 170ms average access time!! Almost as slow as a floppy! What's worse, it does not buffer step pulses. Since nearly all drives today buffer step pulses, it could be that the controller you have doesn't work with unbuffered drives. I think your best bet is to trash the ST506 and cough up $200 for an ST225 or similar drive. -- Larry Campbell The Boston Software Works, Inc. campbell@bsw.com 120 Fulton Street wjh12!redsox!campbell Boston, MA 02146
