ckl1998 -> Sony, Acer, LiteOn CD-RW (9/3/2001 6:20:20 AM)
I recently bought two 4X-10X CD-RW. They are Sony CD-RW650HS
and Acer RWHS74. Previously, I used the 4X-10X LiteOn CD-RW74 that
was bundled with LiteOn LTR-12101B.
Currently I am using Easy CD Creator 5.01 and Nero Burning Rom
I have some inquiry about the above CD-RW. Below is a simple study
that I had made.
Blank Blank* Formatted~
Sony 679,477,248 683,827,200 555,155,456
Acer 679,477,248 688,384,000 558,891,008
LiteOn 679,477,248 688,281,600 558,825,472
* with directCD activated
~ UDF format
1. Why there are differences? Any detailed explaination?
2. After formatted in UDF format, using CR-RW drive the discs were
checked with Nero CD Speed-CD quality check. Acer and LiteOn
CD-RW completed the check process. However, Sony CD-RW failed
everytime. Here was the error,
[14:09:58] Starting CD quality check
[14:15:18] Read error at 60:50.60 (code 030600)
[14:15:18] Test aborted
Then I switched to ScanDisc by directCD. The disc returned no
error. Infact, the disc performed well in read and write mode.
What is actually happen to the Sony CD-RW? Would it contains
error as reported by the above quality check?
3. When checking the CD quality, I found different results by using
CD-ROM and CD-RW drive. Which drive should one use for CD quality
checking? CD-ROM or CD-RW drive?
