Sure. Everything went fine at this time.
Day1: Installed Win7 x64 Pro (SP1 integrated) with IDE and benched a little bit - only 160 MB/s seq. read
Day2: Activated the MSAHCI service via registry and switched to AHCI - benched again: 244 MB/s seq. read
Day3: SSD worked fine + normal shutdown
Day4-6: Just worked with Vista on my HDD (I got both in the laptop) and did not do anything with the SSD
Day7: Tried to boot Win7 - no partition there to boot from
I tried switching from AHCI back to IDE and vice versa - makes no difference. Disabled the ATA Password - no difference.
The SSD shows either 8 MB or the full 149 GB. I do not know what it depends. It changes from boot to boot.
To exclude my laptop, I installed the drive in an Asus U30JC (South Bridge: Intel Ibex Peak-M HM55, North Bridge: Intel Ironlake-M IMC).
It behaves just like it behaves in my other laptop. I checked the drive with Ubuntu booted from USB because can install only one drive.
This is what I got:
ubuntu@ubuntu:/proc$ sudo smartctl -i /dev/sda smartctl 5.40 2010-03-16 r3077 [i686-pc-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: INTEL SSDSA2CW160G3 Serial Number: BAD_CTX 00000166 Firmware Version: 4PC10302 User Capacity: 160.041.885.696 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Sun Apr 24 10:40:04 2011 CEST SMART support is: Unavailable - device lacks SMART capability.

-> No SMART, no partition & strange Serial Number.
I also tried to Secure Erase the drive, but did not managed to do it. I cannot click the run button in the Toolbox. (Yes - I have ejected and reinserted the drive with the Toolbox open and ready to click run)
After that, I tried to install Win7 again - not possible. Neither with IDE nor AHCI.
I really don't know what I should do more. If there is no solution in the next three days, I will bring the drive back to my retailer.
It is maybe possible to reflash the firmware?
Had the same problem. SSD 320 120 Gig, bought it to installa new W7 offit. Shortly after install shows as 8 Meg (!!!)
What worked for me was using autility called HDAT2; you prepare am ISO with that and boot off that. There's a number of choices. The one you need is removing the HPA, Host protected Area, and then set it back to factory default
Now I see 120 G again and the tests run fine.
BIOS also sees it fine.
HAven't re installed W7 yet thiugh
I just discovered this thread.
Looks like you're experiencing the same problem mentioned in this post?
Thank you very much, useful forum thread! Cheers
