Dan,
     Sounds to me like you have a new Maxtor drive.  If so, and by the
sounds of your problem, it sounds like the "MaxTransfer" value of the
drive (it's stored in the Rigid Disk Block (RDB)) is wrong.  This value
controls how much data the drive can read/write in one transfer "gulp"
(for lack of a better term).
     What you need to do is modify the value with a program called
HDToolBox, which may be present in your Workbench partition somewhere.
If it is, you need to run it, select the hard drive, then select each
partition in turn along with the "Advanced Options..." button.  In
the advanced options area you will see the "MaxTransfer" field.  Change
the number in the field to 1fe00.  This has to be done for *every*
partition on the drive.  When you have done this, exit back to the main
screen and select "Save Changes".
      If you do not have HDToolBox, from what I've heard on Usenet, you
can do the same type of operation with RDPrep.  I think the filename
is rdp391.lha on Aminet somewhere.
