- DVD Error Correction Discs

ABEX TDR-821 (Single Sided Single Layer Scratched Media)

The drive reports a perfect reading CAV curve.

Scanning the ABEX TDR-821, show significat number of errors (PIE/PIF), which however can be corrected from the drive's internal error correction abilities. PIE error are kept low when the media is not scratched and got high peaks when the PIF errors are also high. No POF (unreadable area) reported.

ABEX TDR-825 (Single Sided Single Layer Defect Media)

The drive doesn't seem to have any problem with the TDR-825 disc, it shows a perfect reading CAV curve as well. The reported PIE/PIF values doest affect the reading speed, since all error are being corrected from the drive's internal error correction/

ABEX TDR-841 (Single Sided Dual Layer Scratch Media)

Using the ABEX TDR-841 media, we got very good reading speeds. The drive doesn't support dual layer scan with OptiDriveControl (scan stops at dual layer break) so we wont post such scans.

ABEX TDR-845 (Single Sided Dual Layer Defect Media)

The drive has excellent reading curves for both layers. The drive doesn't support dual layer scan with OptiDriveControl (scan stops at dual layer break) so we wont post such scans.

ABEX TDV-541 (Single Sided Dual Layer Scratch Media)

The TDV-541 disc seems to struggle the drive with serious speed drop downs after the 3.0GB till 5.0GB, where all the artificial scratches are placed. The drive doesn't support dual layer scan with OptiDriveControl (scan stops at dual layer break) so we wont post such scans.

ABEX TDV-545 (Single Sided Dual Layer Defect Media)

As happened with the TDV-545 test disc, the drive after 3.5GB till 4.5GB, due to the high artificial errors present on the disc, forced to lower its reading speed to read the contents. The drive doesn't support dual layer scan with OptiDriveControl (scan stops at dual layer break) so we wont post such scans.
