DaTARIUS Scans -

Uncorrectable errors with the specific MID. POFs were reported, while some areas of the disc could not be measured by the DaTARIUS drive, revealing possible bad sectors. The CD-DVD Speed reading test looks good though.

We should note here that POFs occur when the decoder is unable to correct all the data within an ECC block after attempting one pass of PI Row correction and PO column correction. The wording "one pass" is important because a commercial decoder is usually designed to make several passes or attempts during error correction. There is a possibility that bad bytes may be corrected in one of the subsequent passes. The decoders of DVD testers such the DaTARIUS system, use one pass during error correction. As a result, in some cases where POFs are reported by the tester, these can be corrected by commercial players and drives during reading due to multiple passes.
