Windows 7: 0x80070002 error/can't change drive letter

0x80070002 error/can't change drive letter

Hi guys!

I've been getting glitches, blue screen and AMD/ATI errors for a while now. I'm about to get my hard drive replaced by warranty for free, but they asked a lot of money for cloning my current hard drive, so I figured I'd do it myself as I own an external hard drive. As it turns out, I'm much less tech-savvy than I hoped.

I managed to copy all the files I want to keep manually onto my external, but then wanted to do an actual backup as well, as they required a disc to re-install my OS, which I don't have, cause I never got it.

I've managed to create a system repair disc, but every time I try to do a full backup or a system image, it gets to about 30% and then quits with this error code - 0x80070002.

So, I found this - Error code 0x8100002F and or error code 0x80070002 when you back up files in Windows 7 -, and it seems to be scenario 3, that lead me there - You encounter problems when you move data over USB from a Windows 7 or Windows Server 2008 R2-based computer that has an NVIDIA USB EHCI chipset and at least 4GB of RAM -, but after that I got an error saying it's not applicable to my computer. I then found this - Error 0x80070002 when attempting to backup files -, which suggested me to change the letter for the 100MB partition, but as it doesn't have a letter to begin with, it only offers me the 'help' option, rather than the change letter one and now I'm stuck. Is there a way I can change it or is there anything else I can do to backup my OS? I'm not that bothered about anything else (I mean, I'd love to have it but..), as I've got legal copies of Office and necessary Adobe products and I've copied all personal files.

Or, do I even need to bother with this and the warranty IT guy can sort out my OS without an actual disc?

I have a Dell N5010, Windows Home Premium, 2009, SP1, 64bit

You can just link me to a relevant topic, as I'm sure there are many of these, I just can't find the one that would be the right fix for me.

Windows 7 32-bit

I'm no expert, but I've just recently installed Windows 7 after using XP for 6 years. I think all the error code 0X8007002 means is that some folder or directory (or in your case some partition) that Windows 7 backup expected to see isn't there for some reason or it can't locate it for some reason. If I was in your position I would at least do this; I would not select "Let windows decide which files to backup" when I did the backup, but I would select the manual option and select them myself. For now, I would skip the 100MB partition even though you have a lot of your personal files there. Get the OS backed up with your personal settings because this is the most important thing you will need for restoring the image to your new hard drive. As you say, you can always go back and install MS Office and your Adobe programs. If you're like me, you've even saved your "templates" folder for MS Word. This was the most important thing to me because I had a few templates and also a lot of macros written for MS Word processing. I had to install the new "templates" folder from XP into a different folder on Windows 7, but it works just fine when I run MS Word 2003 now.

I've also seen some talk of folks having trouble when trying to transfer the system image from a USB drive to C: rather than from another internal HD. But, hopefully you won't have any problems with that. You've got the right idea--just boot from the Windows 7 reapir disk and select the option for the system image or whatever it is called. I tried it, and it had no trouble locating my most recent backup on my D: drive.
