And therefore the head on the drive must be different to cope with this. Obviously the head of a 40track drive is wider than that on an 80track drive, on switchable drives the narrower head is made double step when reading 40 track disks. There's no way you'll be able to read a mac disk - unless you've got a Mac drive - I believe this is because they use variable speed drives. -- --------------------------------------------------------------------------- - JANET E-mail : vanaards@uk.ac.man.cs.p4 (Steven van Aardt) -- -- Warning this user has been designated for termination on the 21.6.91 -- ---------------------------------------------------------------------------
