I need some help......

Please explain the A1200HD and A4000, both of which come with IDE harddrives?

Block == CHS.  Cylindar, Head, Sector.  This involves the basic geometry of a drive.

Finally about lowlevel formats: Don't be absurd.  No one should ever have to lowlevel format a drive in their Amiga or any other computer. EVER.

Piru is correct, you have posted very erroneous information that could potentially lead to hardware failure in someone else's machine.

Furthermore, much of the information you were discussing was regarding AmigaOS 1.2/1.3, an A2090/1 controller, and very small harddrives.  I can understand where you may think that PrepHD is a lowlevel format, but it is not.  Setting up a MountList, a PrepHD, and InstallHD from AmigaDOS 1.3 is far different than a lowlevel format.

Please double check your information before someone loses hardware.  I understand your enthusiasm, but you did misinterpret the manual.
