Are one of my drives busted?

I have tried to clean install windows 7 64x on my new desktop and it goes too slow for me to think it is healthy. After about 15 minutes it gives me an error code 0x8007045D.
What I want to know is how to make a diagnosis. IDK if I'm having an issue with the optical drive or hard drive. Also, I purchased my copy of windows and was wondering if there is a LEGIT way of ripping it to an iso for backup. PowerISO doesn't seem to want to. I am also interested in that because I know a person who had my problem and he said he had to burn his copy to a different disc to get it to work. My only issue with that is it's a brand new copy of windows and looks almost flawless.

Try testing your drive using the appropriate tool: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

I used ImgBurn and created an iso, which I burned to a DVD and it works like the original (at least boots and starts installation or repair, I didn't' go all the way)

The Microsoft EULA allows you to make a backup copy, so there is no restriction on the disk:


I had a problem similar to your friend's: I had a VISTA disk that would not be read by a certain DVD drive, although the disk was good and could be read by other drives. The drive was brand new and searching afterwards I found out it was not an uncommon issue
