Thanks for the reply. I have an Asus board (P5E WS Pro) with both Intel ICH9R and JMicron SATA controllers onboard. I tried both with my BenQ drive with minimal results on Win7 x64. I'm about to rebuild my PC with some new components, and will probably end up with an AMD SB950 Southbridge on a M5A99X EVO mobo. That should be much more similar to your [working] setup than I have now. Either way, I should be able to transplant my VIA card, so I'm not worried about losing any functionality.
Are there any surefire SATA controller cards that I might be able to purchase along with the rest of my stuff on NewEgg? The VIA card was all the rage back in the days of iPrep and ixtreme 1.4. haha

I re-read your post, and correct me if I'm wrong... but aren't the Hitachi drives "better" with regard to being recognized by a PC? As in, they don't need a particular chipset or special drivers to get a drive letter assigned easily? Maybe this is why you're having better luck than I am?
For those of you out there that everything is working perfectly for... what is your hardware/software setup?
Windows/Linux/etc OS version? 32 or 64 bit?
SATA controller(s)?
360 Drive Model?
360 Interface Hardware? (CK3, CK3i, X360 USB, etc...)
Other factors that I can't remember 10 minutes after rolling out of bed???
I'm on Vista-64 with 16gb of DDR2. Yeah, my build is a couple years old but working great. I use this controller card:
http://www.newegg.com/Product/Product.aspx...N82E16816124011Cheap, easy to install, & recognizes almost everything.
I'm setup like this:
X360usb for slim lite-ons primarily,
Phat lite-on's & Hitachi's are kinda Hit & miss,
can flash a 360HDD in under 30 sec,
rips good with schtrom & XBC before build 350
Sy-via6421 (with drivers removed)
Slim 9504 & all phat drives do great except hitachi
(with drivers installed)
rips good with schtrom & XBC before build 345
Onboard SATA:
Hitachi's do great. I keep a onboard SATA cable hanging out the back mainly for these.
Schtrom & all Builds of XBC seem to rip great.
Remember this is just the setup that works best for me. Plenty of people are getting XBC build 350 to work with X360usb & VIA6421. I just have no idea how, lol.
