Hello, I'm trying to re-use some previously burned CDRW. This is the CDRW ATIP : *** Disc ATIP code information *** ATIP Start Time of Lead-in: 97m25s30f ATIP Last possible start time of Lead-out: 79m59s74f (LBA: 359999) Disc Manufacturer: INFODISC Technology Co., Ltd. Disc Dye: Phase Change(Agin/SD/TE,Ge/SD/TE) Disc type: CD-RW Indicative Target Write Power: 05H Reference Speed: 01H Unrestricated Use Disc(URU): 00H A1 Value: 024CD0H Lowset Usable CLV Recording Speed: 00H Highest Usable CLV Recording Speed: 02H Power Mutilication Factor P: 04H Target y value the Modulation power function: 04H Recommanded Erase/Write power ratio: 0DH A2 Value: 4AD85AH A3 Value: 000000H Maximum Read Speed Supported (with current disc): 32X (4800 KB/Sec) Maximum Write Speed Supported (with current Disc): 8X (1200 KB/Sec) Current Read Speed Supported (with current Disc): 20X (3000 KB/Sec) Current Write Speed Supported (with current Disc): 4X (600 KB/Sec) I'm using the GCC-4480B combo drive with firmware 1.02. 1) I've tried a FULL ERASE (not quick) 2) I've tried so far 6 different software to erase the CDRW's. (Alcohol, Nero, InCD, Blindwrite, burnonce, Clone CD) Normally, i'm getting an LBA error in the middle of each disc. (Or sometimes the erase job is completed very quickly but visual inspection showing only half of the cdrw was effectively erased.) 3) I've tried 5 different CDRW media. (but from same manufacturer) 4) I could write a cd image, but the job will abort with an error at random LBA sectors around the middle of the disc. What could be wrong: the CDRW Media or the Combo Drive ? Thanks.
