DAE Error Recovery:
the DAE function of PlexTools can detect Uncorrectable
Read Errors.
This detection is based on the C2 flag that is read together with the audio data. It is
impossible to correct these errors, but PlexTools offers a choice of smart strategies
that attempt to recover the original data.These strategies consist out of combinations
of re-reading the data and changing the read speed.Depending on the type and se-
verity of the damage, each strategy will give a different result.
The user is encouraged to try out the different strategies and options in order to min-
imise the read errors and achieve the best results: Fast DAE with no Read Errors.
Report Errors only (no recovery action):
This strategy can be used when the
source disc is error-free or error correction is not necessary.
Reduce the speed upon error:
When Uncorrectable Errors are found, the dam-
aged area will be read at a lower speed in order to find an error-free reading.
Read again upon error:
When Uncorrectable Errors are found, the damaged area
will be read again for a number of times (Retries) at the selected speed in order
to find an error-free reading.The optional 'Allow Speed Down' can be used to
achieve better results at lower speed.
Recover the best sector (least errors):
When Uncorrectable Errors are found, the
damaged area will be read again for a number of times (Retries) at the selected
speed. When the errors stay, the sectors with the least errors will be used to re-
assemble the original data.The optional 'Allow Speed Down' can be used to
achieve better results at lower speed.
