1.0 Specifications
1.1 Formatted Capacity
These drives support cylinder-head-sector (CHS) and logical-block ad-
dressing (LBA) translation modes. You can use the Identify drive (EC
H
)
command to verify the address modes the drives support, the number of
cylinders, sectors per track, total number of sectors, heads and other parame-
ters. The Identify drive parameters are listed in Section 3.2.1 on page 29.
Notes:
1. DOS and FAT 16 cannot access more than 2.147 Gbytes per parti-
tion. You must create multiple partitions to access the drive’s full ca-
pacity.
2. One Mbyte equals one million bytes.
3. If the system BIOS does not support more than 4,092 cylin-
ders, it may cause the computer to hang during startup, or it
may truncate or wrap the cylinders. To resolve this issue, the
system BIOS needs to be modified: the cylinder register or
variable must be increased from 12 bits to 16 bits to accommo-
date more than 4,092 cylinders.
