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 III 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 III 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 III 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 III 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

Large to small

If the source is bigger than the target, EZ Gig III copies only the data

which also fits onto the target. This data is copied from the beginning

of the source to the beginning of the target medium.The data which is

larger than the target is not copied and is missing on the target. Generally,

such a copy can only restrictedly be used because possibly necessary

data can be missing. However, if you make sure before copying (e.g. by

defragmentation) that all valid or necessary data is in the front part of the

source medium and that this area is not larger than the target medium, a

copy onto a smaller target medium can also be successfully used.

Automatic troubleshooting

In case of occurring errors, EZ Gig III tries to troubleshoot them the

best possible. If this is not possible, the errors will be mentioned in a

corresponding error statistic in the detailed report after the clone is

complete.

Intensive reading/writing

In case of read or write errors, EZ Gig III uses different strategies in

order to still be able to read or write this data, if possible. The time used

for defective areas depends to a large extent on the respective medium.

According to the medium and its state, several seconds up to minutes can

be needed for the recovery trials. Therefore, it is recommended to always

activate the option SafeRescue because then handling defective sectors

takes place after the copying of all intact areas has been finished. The

process can then be aborted if it takes too long without losing the data of

the intact areas.

Read errors

During the copying process, read errors can only occur on the source

medium. EZ Gig III then tries to read the defective areas immediately after

the termination of the copying process (with the option SafeRescue) with

the help of special data recovery strategies within a single troubleshooting

run. During the troubleshooting run, the number of the indicated read errors

can reduce according to the areas on the source medium, which could be

recovered.

NOTE: Read errors, that occur during the verification run, are not counted

as read errors but as verification errors.

Write errors

Write errors can only occur during the copying process and only on

the target medium. EZ Gig III then tries to read the defective areas

immediately after the termination of the copying process (with the option
