With a Dell Inspiron 6000 I had a dying Sony DVD drive - which I replaced with a 6650a I "thought" was new. Bought on eBay, and found an over-labeled unit with serial and manufacture barcodes blacked out. Am registering complaint with eBay, needless to say. The seller won't answer.
Anyway - I just bought an Optiarc 7530b (online, but not from eBay) and installed it per Dell's instructions. This unit, unlilke the 6650 - hums along beautifully, doesn't freeze and whine.
OK, OK - I know - where's my "beef?" Well - it is just that, unlike the previous drive, it doesn't "lite up" during the boot-up sequence. Aside from that, it works perfectly. Such a beef, eh?
Also - I note that the 7530 is not listed on your Optiarc product list, and there's even a note that the 7540 was the first Optiarc unit. Hmm, I hope somebody can set me straight on this, please!
