Acer sent me 4 cd disks that are known as Recovery 1, 2 and another known as Language disk and a fourth that just says 64bit. As a net book owner, there is no cd burner included. ..so in the event of a crash and etc. I have no way of getting these disks acknowledged..until I bought an external enclosure for my 40 gig hard drive. I am trying to copy these disks to my enclosure HD, which in turn allows me to insert into the usb port with that enclosure to reinstall the OS...but the first two disks have almost identical folder names...so after doing the first one, i get a message that the second one would overwrite the previous titles cause they are identical...do i want to continue...of course not. I don't think i can rename the folders of the second one to get by in the event that i need to install disk 1 and possibly be requested to add disk 2. I do have the backup on my net book ..but how would i be able to use that if it crashes? I wish others who have the Acer win7 net books would tell me how they are going about it. Any suggestions?
