User bytes/sector (ub/sct)

256 - 744 (even number of bytes only)

Sectors/logical block (sct/lba)

1-8

The lowest sct/lba that satisfies the following rules is used...

1. Block Length is evenly divisible by a number 2-8.
2. Quotient of previous equation is evenly divisible by 2.
3. Quotient must be

≥

256 and

≤

744.

User bytes/logical block (ub/lba)

256 - 5952 (See rules for determining sct/lba above for determining sup-
ported ub/lba values.)

Sectors/track (sct/trk)

(See Table 1 on page 13 or contact an IBM Customer Representative
for other block lengths.)
