Geometry
This Mode sets the geometry (Cylinder, Head and
Sector) translation used on the Target drive. CHS
information is stored in the partition table of the
hard drive and is used by the BIOS to determine
from which partition to boot.
The correct setting will depend upon the capacity of
the Target drive and on the BIOS of the PC in which
it will be used. Check with the hard drive and PC
manufacturer to determine which CHS mode is best
as different BIOS systems use different translation
methods for large (over 528 MB) capacity drives.
CHS Translation Modes
Following are the CHS translation modes supported
by the Omniclone Xi™:
LBA (Default) – This CHS Mode will work for most
hard drive and PC combinations and should be
used unless otherwise indicated.
Large – Also known as Extended CHS (ECHS)
mode. It is used on all Compaq and Samsung
computers, some IBM PC’s, IBM Thinkpad laptops,
some newer Dell laptops, and possibly other
computers. It should also be used whenever a
Phoenix BIOS version 4.0 or earlier is encountered.
LBA 8.5 and Large 8.5 – These settings force all
partitions to remain below the 8 GB mark. This is
useful with Legacy motherboards that cannot
support drives larger that 8.5 GB.
LBA-1, LBA-2, Large-1 and Large-2 – These
settings instruct the Logicube Omniclone Xi™ to
“shave off” one or two cylinders from the total drive
size when constructing the Target partition tables.
NOTE: It is important to use -1 or -2 settings for all
Windows 2000 and Windows XP installations.
These operating systems use the unallocated
space to store certain tables required for Active
Directory and sometimes for Dynamic Partitioning.
NOTE: Most of the time, blocking out one cylinder
is enough but two may need to be blocked out to
achieve good results.
Security Identification Number (SID) Issues
The Windows NT, Windows 2000 (previously
known as NT 5.0) and Windows XP operating
systems attach a SID (Security Identification)
number to all files and directories on the hard drive
