Hi - I'd like to share my (frustrating) experience while trying to install Windows 7 onto my 120gb OCZ Vertex Plus drive, with the hope that this experience might be helpful to others trying to get this drive to work.
This drive went into my X61 Tablet (firmware 1.24, AHCI mode enabled; Windows 7 DVD installation via an ultraslim DVD drive in the X61 Ultrabase). Like other TP users on this forum, I was having a terrible time installing a clean copy of Windows 7. After the initial file transfer and first reboot, Windows would give an error "Windows setup could not configure windows to run on this computer's hardware". I noticed that if I replaced warm-reboots with cold-boots (i.e. turn off the computer) everytime Windows rebooted during the installation process, I could (consistently) get to the desktop and download Windows updates (again, by performing cold-boots). However, when all of the updates were installed and it finally came time to shutdown the system, the next time I'd boot up, I'd get a boot-failure message ("missing operating system"); the partition would be missing. This was the same outcome after several installation attempts and I was ready to give up and send it back.
Since the SATA interface on the X61 Tablet, by default, operates in SATA I mode, I thought I'd try Middleton's modified BIOS to enable SATA II. With the modified BIOS, Windows 7 installed flawlessly without any intervention (e.g. no cold-boots). The system booted up to the desktop (about 22 seconds from initial power on), installed all the updates, patches etc. Gone are the boot errors. So far (~ 3 days of constant use), the system has been solid (no BSODs) and the drive gives me a respectable 7.2 WEI score. Programs load up very quickly and it has breathed new life into this machine.
So what can I conclude from this? Well, with an n=1, nothing really. But perhaps with this generation of Thinkpads, the problem might lie with the SATA I connection (or rather, perhaps the Vertex Plus drive doesn't negotiate well with SATA I).
Now that the drive is up and running, it's much, much faster than my old WD Scorpio Blue. Quite pleased, actually.
Anyways, I thought I'd share this experience with other frustrated Vertex Plus owners.
