When you installed Windows 7 a while back, if you selected Home Network option, it gave you a user name and password for accessing it via other computers.

Some people just keep clicking away and don't notice it or remember to write the stuff down. I hope you'll be able to get this rectified as 271 GB is a hell of a lot of stuff to not be able to access.

just what u said there m8 i just kept clicking away is there away round this i remember the yellow box cumin up and saying to write the password down but i think its asking me for the user name and pw for my xp pro pc not sure ive transfered the image from my pc to my desktop gonna try get the funds up to buy an externel hd try it from that i have all passwords etc turned off on my network had enough lol thanks for the reply my friend
