I bought a TDK 1612DLB drive few months ago and it is giving me the headache. Currently I have used the firmware C7S3. My system is a 3 yrs old Acer P4 1.6a with 512 Mb of RAM. OS using is WinXP Home edition with SP2.

My burning software is Nero 6.0.

This is my problem,

I used Nero 6.0 to create data disc to back up my files. Whenever I check the box "verifiy data after burning" it always gives error message. But I am still able to read some disc.

I am using TDK -R media. Some disc are unreadable. And those that are readable MAY not be readable in other DVD Roms.

Moreover, there are some disc which I have backup appear normal at the time when I burn it. But when I tried retrieving it at a later date, it is unreadable in my drive. These disc, strangely, canbe read in my friend DVD ROM.

Just wan to ask, if my CMOS battery is weak, will it affect the drive?
