The Standard error recovery mode is intended for use with drives that have a high number of
read faults. When in Standard mode, the TD2u treats the source drive as a series of 64-sector
blocks (32,768-byte blocks). An error in any 64-sector block causes the entire block to be
treated as an error. This allows the TD2u to move quickly through a drive with many read
faults, but at the loss of some potentially readable sectors near each fault.
In both error recovery modes, the TD2u handles unreadable sectors in the same way. When
the TD2u has determined that a sector cannot be read from the source drive, it fills in the
missing data with zeros on the destination drive. Zero data inserted in this way is also included
by the TD2u when calculating the MD5 and SHA1 hashes for the duplication.
The TD2u treats all media errors on a destination disk as fatal or unrecoverable errors because
each destination disk is receiving a copy of evidence critical to a forensic examination. It is not
recommended to store data to a destination disk with known defects.
Factory Reset (Menu 7.3)
The
Factory Reset
option resets all TD2u configuration settings to the factory state.
Factory
Reset
also physically erases of all user settings and logs stored in TD2u flash memory.
After performing a
Factory Reset
the TD2u retains no user-specific or case-specific information.
The only setting not cleared by a
Factory Reset
is the current date and time.
Internally Stored Information provides additional information regarding data stored in non-
volatile memory by the TD2u.
Duplicator Info (Menu 8)
Selecting the TD2u
Duplicator Info
option displays selected information for the TD2u itself, as
shown below.
