Installed a 90GB OCZ SATA II SSD in a Toshiba M400 and proceeded to build from Win7 Ultimate
 DVD.   When it gets to the "where to instal Windows?" question no drives appear.  The SSD
has been formatted in another machine.  How can I get the SSD to appear?

Not all laptops will boot to SSDs, and some SSDs have compatibility problems.   One thing it could be, does your laptop even support SATA-2 interface speed of 3.0Gbps?  Check toshiba support site, make sure you have latest BIOS, and log a call with them.  There could be an inherent limitation that prevents ANY SSD from working.

I appreciate that that might be the case.  But the thing that attracted me to this forum was a question around getting an M400 to work with an SSD under Win XP.  It looked like they found a solution...

Win7 and XP are completely different drivers, and Win7 has built-in support for SSDs and TRIM.  WinXP treats the SSD as if it was a hard drive.   So WinXp works because it is stupid.  Win7 won't work because it knows you are using a SSD, and there is some inherent problem.  

While I've got access to some OCZ Vertex Pro 2s, I certainly don't have your laptop.  The OCZ site also has a lot of blog entries about what works and what doesn't.   This is a compatibility issue between 2 specific parts, and not one of those generic type questions that can more easily be answered.  So the fast way to get an answer is to find somebody that has the same hardware that either made it work, or confirmed that it didn't.   The OCZ and Toshiba sites are best sites to look at for specifics.

While I completely agree with dlethe that forum users at Toshiba and/or OCZ (or hold out for someone here who has happened to try that combination) would be your best, and that some systems simply cannot use SSD's, you might for kicks and giggles try loading a driver for the storage controller at that screen where it doesn't "see" the drive (use "Load Driver" link on that page), in case the driver is one of the few that are not native to Windows 7:

Good for kicks and giggles but when it came to the crunch the machine didn't "see" the driver either.  I unticked the "Hide drivers that are not compatible with hardware on this computer" and there we had "TOSHIBA RAID Virtual Device (C:\VIRTUAL.INF)" but it didn't load and the process came back with "No drivers found"

First of all you need to check if your BIOS sees the drive. Get to BIOS and see if your SSD drive is listed there. If yes, then see what mode it is set. RAID, compatible or AHCI.

Thanks guys. BIOS could see the SSD very well. I put back an ordinary HDD and found the Win7 install couldn't see that either.  Seems the Tosh M400 needs a driver upgrade for any Win 7 install from DVD.  I had a Win 7 image on there already but via a network install so I hadn't encountered this issue.  A driver download from http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=1598633&rpn=PPM40U&modelFilter=M400-S5032&selCategory=2756709&selFamily=1073768662 worked a treat.  The perfromance of the machine with an SSD is now astounding!

So, I'm glad you got it working and all, but you realize you used the same driver I gave you the link for, right?  And, that the reason you needed the driver was because "the driver is one of the few that are not native to Windows 7"?
