Troubleshooting Guide
Q
: Why do I sometimes see transfer speeds that exceed 3.5 GB/min and then other times as slow
as 200 MB/min?
A
: There are many factors that determine transfer speed. For example, the speed of the cloning
operation is governed by the slowest drive being used. If an older drive is used as either Master
or Target, chances are it cannot sustain a high data transfer rate. Newer drives have faster
electronics and lager on-drive caches that allow them to reach transfer rates of 33 MB/sec or
more.
The type of cloning operation performed can also affect transfer speeds. When cloning FAT16
partitions, it is sometimes necessary to change the cluster class of the partition. In such cases,
the Logicube OmniClone Xi utilizes a more complex method of ensuring it creates a valid Target
drive.
With OmniDiagnostic™ installed and its Recover feature enabled, the Logicube OmniClone Xi will
attempt to recover data from bad or weak sectors found on the Master drive. This is a time
consuming operation that could cause the overall cloning speed to drop significantly.
Q
: The Logicube OmniClone Xi does not recognize my Master/Target drive.
A
: Make sure that the drive jumpers are set to Master/Single. Drive jumper settings can be found
at the drive manufacturer’s web site. Also, check the condition of the power and data cables; they
are rated for a maximum of 500 insertions. New cable sets can be ordered from Logicube.
Q
: My Target drive will not boot. Why?
A
: Please check several things:
First, make sure that the correct CHS Mode was selected for the Target drive. This 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 manufacturers to determine which CHS mode is best as different
BIOS systems use different translation methods for large (> 528 MB) capacity drives. See Section
3: Cloning Modes and Settings for more information on the CHS Mode preference setting.
Also check and make sure that the first partition selected for cloning on the Master drive consists
of a bootable operating system. It is possible to select a data-only partition to be cloned.
However, if it becomes the first partition on the Target, a PC will not consider that drive to be a
valid boot drive.
Finally, scan and check the Master drive for possible problems using a hard drive utility such as
Window’s Scandisk or Chkdsk. Some problems may not show up with casual booting of the
Master, but things such as cross-linked clusters can cause serious cloning errors.
Q
: All but the first partition is missing from the Target drive. How did that happen?
A
: This is usually the result of having the wrong CHS translation mode for the Target drive being
used. See Section 3: Cloning Modes and Settings for information on selecting a CHS mode.
