I have been looking at numerous Sony DWQ-26A and 28A drives on eBay–seller says they come from a Dell Dimension 8400. But there is NO mention of them anywhere on either Sony or Dell websites. Where can anyone get a firmware upgrade or other support for these drives? Very strange.

Begin with browsing the Lite-On/Sony forum and particularly this thread.

Thank you VERY much. Without this knowledge noone would know, as there is no info about this drive anywhere but here that I know of. After research I think I will buy the actual drive, LiteOn IT SOHW-1693S, directly from Newegg in a retail bundle for $48 plus $2 shipping.
