| AFAIK the BenQ DW1650 will scan at 8 ECC regardless of this setting. The setting can be used for NEC and Sony NEC Optiarc drives, however, and 1 ECC scanning provides the most correct information for those drives when comparing with ECMA standards.

| I scanned a disc two times. First with 8ecc and then with 1ecc. There is some difference but I don't know if it's normal. But I like the 1ecc scan  |

| DrageMester is right.  Simply, just check the "Statistics" window that pops up after scan. 1ECC = ~130k+ samples, 8ECC = ~17k+ samples taken. |

| Update: More information about this topic has been posted in this thread: CD-DVD Speed Disc Quality (PI/PIF) Test (link is to the start of the relevant discussion) It's actually possible to scan at 1 ECC at the 4x (CAV) scanning speed if you press the "Advanced" button before scanning. The 8/1 ECC scanning interval in the options window is ignored however - it's the pressing of the "Advanced" button that changes the drive to scan at 1 ECC but only at 4x CAV. The mystery is explained by ErikDeppe here in that thread. |
