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

Large to small

If the source is bigger than the target, EZ Gig will direct you to the Data
Select feature. EZ Gig’s Data Select provides a simple method to deselect
data folders from the cloning process. EZ Gig will only allow to proceed
with the clone, once the available capacity on the target drive is a positive
value.
