Simulate a CD-ROM in RAM

Hi,

How do I 'copy' a whole CD-ROM into RAM in order to conduct fast searches on databases? I'm running XP with 1Gb of RAM. I appreciate that I will have to 're-load' it after every start-up.

I realise that you can simulate a CD-ROM on an HDD for faster than CD data access searches, but how do you make it really fast by using RAM?

I'd appreciate someones help.

Thanks.

Copy a CD into a RAM Drive, WOW

Why not just use the HDD and fool the OS into thinking its a CD it will run a LOT faster (not as fast as RAM i'll grant you) but you wont have to reload it all the time

Make you HDD think it’s a CD

VirtualDrive emulates your computer's CD/DVD-ROM drive, which enables you to run CD & DVD programs directly from your hard drive without the use of the physical CD/DVD-ROM drive or the actual disc. VirtualDrive is a MUST HAVE for gamers, music lovers, travelers and laptop users

Thanks Pete,

Yes, I've done this before and it does speed things up. However, the number of data accesses that I need to do albeit automatically are still calculated to take just over 23 days running 24/7 !! I'd really like to up-load it all into memory.

WOWsers!

OK - The only time Ive seen anything like the Size RAMDrive you require is in one of two enviroments

1. Windows XPPE enviroment, theres a disk --- google for XPPE +superCD and you will find it, it can load entire CD iso images into memory.

2. The other, Ive not heared of for a while -  there was a fad going round for a system called HyperOS where Everything ran in Memory (OS apps services the whole shooting match) and you could switch between as many operating systems as you liked, It might be a scrapped concept now but have a hunt anyway :)

Thanks Pete,

You've certainly got me on the right track. I really love the 2 or 3Gb HyperDrive!! You also sparked off some other thoughts regarding RAMDrives, and I've found some good info that I think may help.

This is the first time I've asked a question on Experts Exchange - you've given me a good feeling about it. Thanks!
