I just had to change the CD Burner in my older WIN 7 ultimate System. The CD Burner is connested by SATA and the same way like the Burner installed before this one.
The Problem is that the time for burning a CD has dramatically increased!!!
The Burner itself works good with XPBurner, 48x speed is the result here.
It is a Samsung S-ATA SH 224 (model SH-224GB/RSMS) FW= SB00
any idea would be welcome....
