I have a several part post .
1) Can an OS be place on a USB drive boot and run ?
2) Would the USB drive be faster .
3) If I were to run it on the interior port on an add on USB 2.0 card would the heat inside the case affect it ?
4) How stable is the memory on a USB drive ? Is it solid state , or is it a micro drive ?

My reasons for asking is I test software (just for me) to see how it will effect my computers and network . I could place the OS on two 1gb USB drives , not using one of the drives . Test the software to see how it inter-acts . When I am finished wipe the drive and use the unused drive to copy the OS back to the wiped drive . I think , not know , that if the USB drives are solid state the tranfer should be as fast as the USB and computer will allow . I would use Digital Dolly , a P-III 500 with 768mb RAM if this is possible .
I know nothing about USB drives so please don't infer I believe this will work . If 1gb drives were cheaper I would test it and let you know the results . ALL opinion and advise are welcome .

So these are usb flash disks? Not external hard drives with a usb interface?

Does your bios support booting off of a usb drive?

Correct the key chain drives . I guess that would be flash . Not a normal drive in an external enclosure . The computer I selected can boot from USB .

Format the key with :

Download a boot image from :

http://www.%20bootdisk.com/

Write that image to the flash with:

Now set the bios to start usb first. Plug it in and reboot. It s hould boot off of it. Getting xp to boot off of it is an unknown as of now but you can attemt to install xp onto it and see if that works.

Now that you mentioned XP .Since I am going to reinstall to the USB ,If it works I should be able to load a copy without registering it since I will delete and reinstall in less than 30 days ...Yes?
I plan at this time to load ME since most of my computers are running that .
I don't have the drives yet , but I will go buy a small 64mb or 128mb to try booting .

I have no guarantee this will work. It is somewhat of a untested technology. I am pretty sure my isntructions will get the flashcard to act like a boot device, but no guarantees you run an OS off of it.

I found several USB flash and key chain micro drives (also USB) on PriceWatch .

128mb $27+
512mb $45+
1gb $70+
2gb $150+
4gb $288+

I will start with 512mb and win95 just to see if it works . The spec on the merchant websites report 25mb transfer rate . Thats not as good as a HD . I forget what USB 2.0 is right now .

Acklan, to the best of my knowledge 95 doesn't support USB. It wasn't until 98SE that it became any good.
