WD SATA Hard Drive nomenclature help

I bought a Maxtor SATA drive 6L200SO, 200GB last year. Yeah, I know already, no need to say anything. It's now gone crap, giving bad sectors corrupting the partition table and some data, rending the drive looking as if it were unformatted. One data recovery and $400 later... sigh. I knew it was a mistake to go away from my trusty Western Digital. I have drives from over 7 years ago still working just fine.

(No, no backup, no recent ones anyway, none since I went to Win2000 and had no longer my copy of Ghost from 98SE days. I need to rectify that.)

So I'm looking for a replacement. As I had barely filled a third of the drive, I think a 200 or 250GB is more than enough since I'm spending enough on the recovery as it is. Checking some local merchants' sites, they list some WD SATA as "2500AAJS" and "2500KS", but checking WD's site, it should be KS and AAJS. Seems they mistyped the AAs.

But more importantly: what are the major differences between the Caviar SEs and the Caviar SE16s, other than the (negligible in performance) larger cache? I've read that some mid-size SATAs have single platters, and other multiple platters; is there a way to know? WD doesn't tell, and single-platters are seemingly faster in response time, and cooler, and use less energy (duh, only one platter to search). Would it also make them cheaper? Up here, $67 for a Caviar SE16 250GB seems... suspect, especially when it's $80 elsewhere.

Input and experienced advice would be welcome. Thank you!

I don't have the information myself, but you might try e-mailing tech support @ Western Digital. They have been pretty good about responding to requests for information like that in my experience.

I believe a Se16 contains two ~130GB* platters(WD uses a weird scale, 1000 MB = 1 GB| not 1024 MB = 1GB) So it formats to under 250 GB in windows.

Hajpoj: I've never seen a hard drive format to its listed spec ever, always less, but that's okay, I've never filled a hard drive yet either. :) As long as Win recognises it... If the SE16s have two platters, does it mean the SEs have one - or is it "more than two"?

Fullmetal Chocobo: I was hoping I'd get illuminazting details from experienced members before going that route... :D
