I would like to thank EACH and EVERY ONE OF YOU who replied to this or the 851S thread.
THe recent thing, of not recognizing the drives, was a strange strange thing, probably caused by infamous mtkwinflash thing. Something went wrong and none of my drives except the dvd-rw was not recognized. Now I know why dvd-rw was recognized and others were not, the reason was that computer took it as a new drive and installed drivers for it. Apparently, when I reflashed it, computer took it as with the other drives, and because of some software malfunction, none of the drives were read.
THe solution to this problem was obvious (and I can see why nobody suggested it, as it was so obvious). I had to uninstall the drives from the system, and it reinstalled them on reboot. Everything works now, from dvd-rw to cd-rw to virtual drive and everything else.
So, now that everything seems to be running so fine, I want to thank you all for helping me in need. Special thanks to c0deking and please (its harder each time to use this username in sentence ).
This was a valuable experience, since Im studying computer science and will go all round IT related things, including hardware and computer full from scratch setup. This comes in the end of this year though, so Ive got time to cause some extra probs in my computer, and hopefully some with ODD so I can return here for assistance
You guys have been great. Thank you
