1.1.2 Supported CHS translation geometries

These drives support any translation geometry that satisfies all of the following conditions:

•Sectors per track ≤ 63

•Cylinders ≤ 16,383 (for drives over 8.4 Gbytes)

•Read/Write heads ≤ 16

Note. The CHS addressing supports capacities up to 8.4 Gbytes. To see the full capacity of drives greater than 8.4 Gbytes, use the LBA addressing mode.

The ST317242A logical cylinders are:

Logical cylinders=33,683,328/(logical sectors per track × logical heads)

The ST313032A logical cylinders are:

Logical cylinders=25,434,228/(logical sectors per track × logical heads)

The ST310232A logical cylinders are:

Logical cylinders=20,005,650/(logical sectors per track × logical heads)

The ST38422A logical cylinders are:

Logical cylinders=16,841,664/(logical sectors per track × logical heads)

The ST34312A logical cylinders are:

Logical cylinders=8,420,832/(logical sectors per track × logical heads)
