4.3.2 Imaging
An image, also known as disk-to-file duplication, copies the source drive to a series
of files (sometimes called segments or chunks) on the destination drive. TX1
supports EnCase file formats ex01 and e01 and raw file formats dd and dmg.
Compression is supported, and enabled by default, with ex01 and e01 file formats.
File sizes from 2 GB per segment to Unlimited are supported. Smaller segments
create more directory entries and Unlimited creates one large file segment.
Note: Not all image file size options are available in all situations. Due to
filesystem addressing limitations, FAT32 formatted destinations have a
maximum file size of 2 GB.
When imaging, the destination media must first be formatted with a recognized
filesystem. Format destination drives by selecting the Format media utility in the
drive details screen. The drive details screen can be accessed through the
Destinations button on the Home screen or through the Select Destinations screen
during setup of a duplication job.
If the destination drive is smaller than the source, a dd or dmg image will not fit on
the destination drive. However, if using ex01 or e01, the source drive may fit on a
smaller drive because these formats can compress the data before writing to the
destination drive. There is no guarantee that the data will be compressed enough to
fit on a smaller destination drive, especially if in cases where the data is mostly
incompressible such as encrypted data.
Note: Use extreme caution when attempting to copy a source drive to a same
size or smaller destination drive. Image file formatting adds overhead and,
when coupled with incompressible data (such as encrypted data), a larger
destination drive may be needed.
4.3.3 Performing a duplication
To perform a duplication:
1. Follow the steps listed in “Connecting drives” on page 70 to connect the source
drive and all relevant destination drives.
2. From the Home screen, tap the Duplicate icon. The Duplicate job setup screen is
displayed.
