Logicube SuperSonix User’s Manual
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 Settings
Following are the CHS modes supported by the
SuperSonix and Solitaire Turbo USB Client:
•
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 SuperSonix or
Solitaire Turbo USB Client 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.
Most of the time, blocking out one cylinder is
enough but two may need to be blocked out to
achieve good results.
SPEED
This setting cannot be changed. Since the
SuperSonix is connected to the computer via a USB
connection, the only available speed setting is USB.
