Error Recovery Modes

The TD2u supports two different error recovery modes, Exhaustive and Standard. Both modes
refer to the way in which the TD2u recovers from read errors on the source hard disk.
In the Exhaustive error recovery mode, when the TD2u detects a read fault, it begins a retry
strategy that attempts to read each sector in the 64-sector block that contains the error.
Exhaustive mode therefore produces the most complete destination image. However, if the
source drive has many read faults, the exhaustive strategy used by the TD2u can also be time-
consuming.
Default
Specifies the maximum number of errors
One
allowed on each operation on the source drive.
Specifies if, at the end of an imaging operation,
the TD2u should automatically perform a hash
Prompt
verification of the destination(s), prompt the
user, or do no verification at all.
Specifies the type of wipe to perform.
Pass is one pass of zeros across the drive.
Multiple Pass
Single Pass pass of ones and a final pass of random data.
For some SATA solid state destinations,
Erase is a very fast wipe provided by the drive
manufacturer.
