More than likely I'll leave something out in my discription. I just bought a new hard drive. So I set the jumpers on both drives and now made the new one drive C:. I then istalled Windows, and started to install the usual stuff(antivirus, spybot , internet and so on). I then started to copy some files from the old drive (used to be my drive C:) I coppied most files no problems, until I got an error copy a zip file. It seemed to copy other zip files, but now it won't copy this one and many others. So it copies some zip files but not others. The ones I can't coy I can't do anything with. They are not read only or whatever else security there might be. So now if I reset the jumps on both drives to make my old drive , be the drive C: now and the new drive I jusst bought is now drive D:. I can now copy those very same zip files that I couldn't with the other drive as drive C:. I tried useing regular windows zip instead and I get the same thing. If I now create a zip file with this setup and change the drives around again, I can not read the zip file I just created, when booted up from the new drive I just bought. I tried to make sure I don't have anything funny set in the winzip program that creates a zip file. I am useing admin rights in both cases. I can read and write zip files with the new drive. Like I said, may be forgetting some of the most important info, but I hope with this much someone has seen this problem before. Thanks guys.
