I have this burner/ reader but it is very choppy and would like to replace it but can not find out where to buy one. Can anyone help?
Hi and Welcome!
before you go out for shopping, you may please go through this: http://club.myce.com/f61/troubleshooting-enabling-checking-dma-windows-vista-xp-2000-me-9x-101616/
Apart from that,
laptop drives are heavily customised to fulfill the wishes of the respective laptop manufacturer:
there is often a custom frontplate, and - more important - the drives have different master/slave/cable select settings which can’t be changed that easily as with desktop drives since there is no jumper.
So I suggest to find out, what are the reasons for the problem you are experiencing. Besides the DMA issue, also bad media or a dirty lens may be the culprit.
