3.6.2 DOS 1 GByte Limit
All current versions of DOS are limited to 1024 cylinders per drive. The standard translation
scheme for SCSI host controllers, using 64 heads and 32 sectors, gives a maximum capacity of 1
GB.
To eliminate the 1-GB limit, Adaptec's extended translation feature uses 255 heads and 63 sectors,
extending the disk drive capacity limit under DOS to 8 GB.
If you have already partitioned a large hard disk drive with
one translation method, conversion to another method
erases the data on the drive. Be sure to back up your disk
drive prior to any change in the translation method.

3.7.1 with DOS 5.0 and above
NetWare 386 (version 3.0 and above) and some versions of UNIX that do not share the 1024
cylinder limit of DOS do not require extended translation to support large disk drives and should not
be enabled.
