It's happened at last, got my first coasters
NEC 3500 with official f/w 2.18, RecordNow Max 4.61 and a 25 disc tub of Datawrite DVD+R 8x (12x with 2.18 f/w) PRODISC-R03-003 media code!
Every disc so far (about 8, 6 burned @ 12x and 2 @ 8x) have produced dips in Nero CD/DVD speed Transfer Rate test at roughly the 3.8GB mark, and some even produce a NO SEEK COMPLETE error at around the same point (CRC errors when file copying data back to HD)! Even burning at the rated 8x speed produced bad dips in the Transfer Test!!
I've had a tub of these before (all from SVP.co.uk) and all 25 discs burned fine, even burned the last 5 in the tub at 12x with no problem when the new 2.18 f/w came out!
Also created a Data Disc in Nero CD/DVD speed to test them, can anyone tell me what it means? Notice the dip at 3.8GB doesn't go all the way down like the others (this is where I get problems reading back!!) and at the 4GB mark the line has some uneven bits!
This is the same disc run through the Transfer Rate test:
No need to tell you it doesn't look good!
Burned a RITEK-R03 at 8x and that reads back fine in the Transer Rate test, but it was my last one!
Does this look like a bad batch of discs as all Transfer Rate graphs for this tub of discs have dips at the 3.8GB mark and about 4 have failed at that point.
