Have a look at this page:
http://www.dbpoweramp.com/secure-ripper.htmSpecifically the part that says:
QUOTE
Firstly we thought it was important to move away from the [read block][re-read block] & compare method, this method jiggles the CD drive backward and forward head many times a second causing stress to the drive (in Illustrates opinion). A new strategy is to rip in complete passes (AccurateRip is able to jump in and stop a rip after any pass it if agrees with AccurateRip).
Earlier on it specifies that these are done in burst mode:
QUOTE
Multiple burst passes cause little stress to a drive.
I'm not making this stuff up.
Now if it fails AccurateRip and you're using burst mode, simply switch over to test mode and rip again. If the CRCs change from
black to
green then you ripped the same thing twice in a row (the same as doing test and copy using EAC). If any track has a CRC in
red then there was an error either with the copy pass, test pass or both. In this case dBpowerAMP's secure mode may get you an accurate rip.
But to say burst is more accurate than secure in dBpowerAMP is absolutely incorrect. In the world of EAC it isn't correct either as it really depends on the condition of the disc being ripped and the drive doing the ripping.
