I am trying to install Windows 7 and when it gets to the point of copying the files to my 8gig USB drive it craps out and says unable to write to the drive.

 

Is there any tips or tricks that I should know about? Should I be using a Dual Layer DVD instead of the USB drive?

 

Thanks for the help.

    From what I recall, Windows 7 only needs about 2.5-3GB of space to create the bootable install media.  What method are you using to try to create the bootable USB stick, and from what source are you getting the install files to put on the USB stick?

    4G is the correct size for the Windows ISP, but still need another thumb drive, that's for the drivers, and they are less than 1G

     

    Stop what you are doing and read the Boot Camp documentation carefully, you are doing it wrong.

     

    Backup your machine before going any further.

    Well, if you have partitioned/formatted your USB drive using a Windows computer, it may be in an NTFS format, which Mac can't write to natively.  I also know that some USB drives have a "hardware write-protect switch" to make the drive read-only.  If your drive has one of these, it could be switched to the wrong setting.  I've even heard from some people that MacOS Lion (and newer) cause their "write protect switch" to act as if it is "on" no matter if the switch is on or off, but if the switch is somewhere in between, it seems to work for them. There is an outside chance that you could be impacted by something like that.

     

    I know I've downloaded Windows 7 ISO files from Microsoft Volume License servers and from MSDN at work, and all of them have been less than 3.5GB, so I do wonder what all is on your 4GB ISO file to add an extra 500MB of space to the ISO file.  Hopefully your ISO is from a reliable source and doesn't come with its own pre-installed security risks...
