Read Performance Part III: Scratched CDs
For this test we created a V-shaped scratch on a commercial CD pressing.
Quite a few drives will simply throw up their hands in horror at a scratch like this.
We tested the surface of the disk for damaged or unreadable sectors using Nero CD Speed's scan function.
The drive was able to read all sectors. Only 8.56% were reported as damaged.
The FrisbyII turns in a creditable performance in this discipline when compared with its direct competition.
| Error-CD | Good Sectors | Damaged Sectors | Unreadable Sectors |
|---|---|---|---|
| Liteon LXR24101A | 91.31% | 8.69% | 0.00% |
| Waitec Frisby II | 91.44% | 8.56% | 0.00% |
| Yamaha CRW-F1UX | 95.84% | 0.00% | 4.16% |
Not only that, but our final CD quality check diagram shows that the drive takes the "problem area" calmly in its stride.
The vertical, yellow lines indicate areas with damaged sectors. Other test candidates tended to slow right down here. But not the FrisbyII. It carries on reading right through the faulty portion with barely a murmur.
