Limit capacity ÄÄÄÄÄÄÄÄÙ
On drives less than 33.8GB, Limit Capacity jumper sets the
default
cylinder translation to 4092 to solve issues with certain
BIOS that
only auto-detect. Total available sectors are still at full
capacity
as reported via Identify Drive data words 52 - 61. On drives
greater
than 33.8GB, Limit Capacity jumper changes total available
sectors
as reported via Identify Drive data words 60-61 to 33.8GB.
The ATA
Read Native Max and Set Max commands may be used to reset
the true
full capacity. Third party partitioning software may be
needed to
achieve full capacity when using this option jumper.

Set CMOS hard drive setup to Auto-Detect with LBA mode
enabled.
Some systems BIOS have capacity limitations.
Types that have been identified are:
a 528MB limitation (CHS[1024x16x63]x512 = 528,482,304)
a 2.113GB or 4095 cylinder limitation
a 3.262GB or 6322 cylinder limitation
a 4.22GB or 8192 cylinder limitation
a 8.45GB Standard INT13 limitation
(CHS[1024x256x63]x512)
a 33.8GB or 66,060,287 LBAs limitation
and, if exceeded, may cause the system to hang during boot,
capacity reduction or it can truncate or wrap the cylinders
when
auto-detect options set in the CMOS.
DOS 16-bit FAT file system cannot access more than 2.147
Gbytes per
partition. FAT32 file system can create single partitions
and
logical drives up to 2TB.
FAT16 based operating systems are also limited to 8.4GB.
New
INT13 Extensions and LBA mode in BIOS and FAT32 based
operating
systems are both required to acheive full capacity.
Other FULL-CAPACITY solutions include third-party drive
preparation
software, system BIOS update which supports LBA mode or
third
party bios driven host adapters.
Default CHS translation:
16,383 cyl, 16 heads, 63 sectors = 8,455,200,780
