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 nd 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 verication 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 x 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 xed 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 congured 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 rst 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
