Duplication/ Image Type Hash Type Options Notes
E01 MD5 and SHA-1 E01 format does not
currently support SHA-256.
MD5 and SHA-1 forced on
together since E01 format
cannot support SHA-1
alone, and it was decided to
not allow MD5 alone to
simplify setting
configurations.
EX01 MD5 and/or SHA-1 EX01 format does not
currently support SHA-256.
Can select any combination
of MD5 and SHA-1
(including none if
verification is not required)
since EX01 format can
handle all of them.
Error Granularity defines the granularity of failed reads from the source drive.
The default setting of Standard attempts to recover data down to a 32 kB
resolution. The Exhaustive setting attempts to recover data down to a single
sector.
Note: The default error granularity setting is Standard, which will result in
a minimum chunk of 32kB of source data (64 sectors for a 512B sector
drive) that will get skipped and filled with zeros upon completion of the
attempted reads (assuming no reads were successful). If this condition is
encountered, consider changing the error granularity setting to be
Exhaustive, which will result in repeated read attempts of the error region
with decreasing sector sizes. This will maximize the amount of recoverable
data and minimize the sectors that get skipped and filled with zeros.
Error retry defines the number of times TX1 will attempt to read sectors with
errors before skipping the sector (and using a fill value of zeros). Be careful
when selecting a value of 10 or 100 as it will drastically increase the duplication
time when imaging source drives with hard errors.
7. If at least one destination Job type is image, then Step 5, Image Settings, is
displayed as the last step. To change the image settings, tap the 5 or Image
Settings heading.
