I don't like the PATA cables so I bought the 16a7. I don't intend to buy any more PATA.
I don't know how this drive compares with the 20x. Does anyone know?
I even had to buy a PCI to SATA card because the two on-board SATA ports are used by my hard drives.
20x speed isn't important to me. I don't burn many discs and I still haven't bought any 16x media. I suppose I will when my stock of 8x is gone, but that will be a while.
Are you saying your drive still works but burns at 1.7x to 2.4x? Maybe the problem isn't with your drive. Are you stuck in PIO mode?
