setup. Please consult your computer manual on how to change this setting
since it may be named differently according to the respective BIOS. In
most of the cases, you can find it under the name USB Legacy Support or
USB Keyboard Support (often under Integrated Peripherals or Advanced
Options).
NOTE: In some of the cases, problems with the PS/2 keyboard and/or
mouse occurred with an activated emulation for PS/2 devices. If you do not
use any USB input de-vices, please switch off the PS/2 emulation in the
BIOS setup.
General problems
Slowed down system
If you think the speed of the total system or the copying speed – also with
IDE and SCSI devices – is too slow, a USB controller can be the cause,
even if it is not used.
Read, write and verification errors
If EZ Gig reports errors, these are usually defective areas on the
respective medium. However, general problems with the hardware
can possibly also cause (putative) read and write errors. This is mostly
noticeable by a very high number of displayed errors. First of all, try
to fix the problem via the help instructions for the respective hardware
types (IDE, SCSI, USB) because the causes are usually found there. If
the problems cannot be fixed this way either, deactivate step by step the
following options, at best in the indicated order:
• CachedMemory
• Read cache and write cache
• FastCopy
• DMA
• SharedMemory
If the problem does not occur any more after having deactivated a certain
option, the previously deactivated options can be reactivated as a test.
IDE/ATA/SATA
Hard disk not recognized
If EZ Gig does not recognize a hard disk, there can be several reasons.
Perhaps the controller which the disk is connected to has not been found
(See next section: IDE controller not found). A further possible reason can
be a non-standardly connected hard disk. This is for example the case if
a hard disk is configured as slave and if a CD/DVD drive or no drive at all
is connected at the same IDE channel as master. Normally, EZ Gig can
handle that, too.
NOTE: If an SATA hard disk is not recognized, this can also be due to the
used SATA controller.
IDE controller not found
There are the following three reasons why EZ Gig has not automatically
recognized an IDE controller:
• The IDE controller/channel is deactivated, e.g. on an onboard IDE
controller. Activate the IDE controller/channel via the BIOS setup.
• Standard IDE controllers (ISA) are not taken into account if PCI
IDE controllers are available. Connect the respective hard disk to a
PCI IDE controller in this case or deactivate the PCI IDE controller
or controllers.
• The used controller does not correspond to the PCI IDE standard.
Although most controllers support this standardized programming
interface, there are some controllers which have only a proprietary
programming interface. Connect the corresponding drives to
another controller (PCI IDE controller).
Source & Destination Size Differences
Equal Size
If source and target are of the same size, EZ Gig creates an absolutely
identical copy(clone). On this clone, all sectors on source and target, from
the first to the last sector, are 100% identical, provided that the process
was error-free.
Small to large
If the source is smaller than the target, EZ Gig copies only the data that
is available on the source. This data is copied from the beginning of the
source onto the beginning of the target medium. The area at the end of
the target medium, which is larger than the source, remains unaffected.
Apart from that the unaffected area remains possibly unused during a later
usage, such a copy is usually comparable to a real clone as far as the
capacity of use is concerned because the target contains entirely all data of
the source
