Effects of moving TMP/TEMP directory & disable Pagefile on boot drive

I'm using Corsair SSD as Win7 x64 boot drive, and I moved both User & System Variables TMP/TEMP directory to a new common TMP directory in another hdd (Drive D) & also disabled pagefile on my boot drive (but enabled it for Drive D).

Question is, what happens if I take off my hdd (Drive D:) and Win7 / applications need a temporary directory which doesn't exist anymore ? Will Win7 be smart enough to create a new temp dir in the original location ? I wonder if the dependancy on the hdd as TMP directory becomes critical.

About pagefile, I understand Win7 needs a min pagefile of 400MB on boot drive to allow memory dump. What happens if I disable pagefile on boot drive & enable it on another drive ? Will memory dump work ?

Thanks

Why did you move the temp directory and page file?

Why remove the HDD when presumably you use it for data and temp files etc:?

I don't intend to, but I just want to know if removing the hdd temporarily (for some causes like RMA, etc) will cause any trouble booting into Windows or running applications with the SSD alone. I don't like the idea of dependancy.

Pagefile is obvious, it is too large & the space of SSD is too precious for me.
I move temp directory to hdd because I want to manage all temporary files (incld firefox, ie, etc) under a single partition specially for that purpose. Besides, I find with my daily routines (lots of video encoding, gaming, zipping/unzipping files, etc), my daily writes to the SSD is quite high about 30-40 GB daily. While I realize the SSD has the durability, I find it unnecessary when I don't see much improvement compared to placing the temp files to hdd.

I ran Windows 7 on a desktop without hiberfil.sys and pagefile.sys and experienced no issues. You can relocate the page file to anywhere you require, even a separate storage device.
