AHA-1510A/20A Series User's Guide Using Fdisk To install a new disk, or to repartition an existing disk, use the fdisk DOS utility as you normally would. The cylinder size increases to 8 MBytes when you enable extended translation. The size of the partition you request must therefore be a multiple of 8 MBytes. If you request a partition size that is not a multiple of 8 MBytes, fdisk rounds up to the nearest whole multiple of 8 MBytes. Extended Translation Questions and Answers What happens if I enable extended translation with SCSI drives smaller than 1 GByte? Drives handled by the AHA-1520A/1522A BIOS use extended translation if their formatted capacity is greater than 1 GByte. Drives smaller than 1 GByte of formatted capacity use standard translation regardless of whether extended translation is enabled. What if I have more than two hard disk drives connected to the host adapter? AHA-1520A/1522A BIOS supports up to two hard drives. With additional software, the AHA-1520A/1522A can support up to 24 hard disks. See Adaptec EZ-SCSI on page 4-1.

Using Fdisk
To install a new disk, or to repartition an existing disk, use the

8 MBytes when you enable extended translation. The size of the par-
tition you request must therefore be a multiple of 8 MBytes. If you
request a partition size that is not a multiple of 8 MBytes,
fdisk
rounds up to the nearest whole multiple of 8 MBytes.
