Any clues ?

Thx in advance

Use overburning and burn them, then you’ll see.

Thx chef for your reply but… done that already. Discs not readable above 91% (tried 3 discs - 2 using nero and 1 using dvddecrypter) - I’m trying to burn a 790MB iso I created using cdimage.

bump :iagree:

Test it using CDSpeed and post the picture here please.

Get CDSPEED v3.55 at http://www.cdspeed2000.com (also comes with Nero : www.nero.com ).
Look in the menu -> extra -> overburning test with a blank 90 min in the drive.


current DVDRW ODD’s :
16x : Pioneer DVR-108 (1.14 >NIL), Philps 1640P (Benq fw B7S9), NEC-3500AG (LDv1_1.4 final)
12x : 2x Plextor 712A (1.05) , LG GSA-4120 (A102)
8x : NEC2510 (Herrie 1.07v2b5) , Pioneer DVR-107D(1.18 >NIL), Sony DRU-700A (CG3E)
4x : Sony DRU-500A (2.1a) , Pioneer DVR-106D, LiteON 411 (FS0K)
2.4x : HP200i, Ricoh MP5125A (+R/RW only)

Unfortunately, cdspeed locks up the drive while testing at about 91%… So then I have to reboot.
