Question about HP dvd740i DVD±RW Dual Layer Burner
I have been burning CDs and DVDs for several years without problem. I decided to use an old Sony CD-RW to transfer some files. After burning files to the CD-RW, my HP dvd740b doesn't recognize blank CDs and DVDs anymore, only CD-RWs. It reads those media, but when I try to burn a CD or DVD, it repeatedly prompts me for a CD-RW. I'm using Nero Express 6, but I've tried other programs with the same result. I've uninstalled and reinstalled device drivers, firmware, and Nero several times. I've deleted the upper and lower filter entries in the Registry and read most of the relevant MS Knowledge Base articles. I used the Nero cleaning tool, but it doesn't delete all Nero personal settings as advertised, so my best guess is there are some leftover files or registry settings that limit burning to only CD-RWs. Either that or the burner is about to die, but why would it continue to read CDs, read DVDs, and burn rewritables without problem?
I'm pretty good with PC troubleshooting, but this one has me stumped.
BTW, My homebuilt is running Windows XP Home, SP2, Pentium 4 3.0 gHtz, 1.5 gig memory, plenty of HD space, no games, McAfee firewall and virus protection, and Spybot Search and Destroy.
i think you,ve hit the nail-on-the-head.
The laser has to power up highrer to write a DVD, or ocassionally have a dual laser. 1 for read/write CD. And 1 For Read/Write DVD.
Certain cd roms, only use CD- media. it,s probably worth checking which media is supported by the drive.
Also check the drives aren,t conflicting, on the same ide channel, sometimes swapping channels, ide primary/secondary can help, or swiitching Master/Slave/cable select jumpers on the drives Themselves.
