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.
Automatic troubleshooting
In case of occurring errors, EZ Gig 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 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 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 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 proper
troubleshooting run. During the troubleshooting run, the number of the
indicated write errors can decrease according to the areas on the target
medium, which could be recovered.
Verification errors
When the option Verifying is activated, EZ Gig executes a verification run
after the copying process. A verification error is counted if the data of two
sectors on source and target do not correspond. Furthermore, read errors,
which occur during the verification run in one or both of the areas to be
compared, are also counted as verification errors. Therefore, the number
of verification errors gives you absolute information on how exactly source
and target correspond to each other after the copying process. In case of
an error-free copying process, EZ Gig should not report any verification
errors and signalize a 100% conformity of source and target.
