Cannot Backup error 0x81000019. Cannot create shadow copy...

For those people who stumble upon this thread and are pulling out their hair thanks to error 0x8100009, I may have a solution that's not as invasive as other procedures found on the net. I have a samsung laptop with both a C and D drive and bought a western digital 2 tb external drive for the express purpose of backing up. When I attempted to create a repair disc, I got the big red X and was told the repair disc could not be created. I fixed that by turning off my internet security. Then when I attempted to run back up I was faced with the dreaded 0x8100009- cannot create a shadow copy blah blah blah. I've spent way too much time looking for solutions from every forum on the net. I tried turning off my security, deleting the language packs and a myriad of other suggestion. I'm an absolute computer noob so if I could do this, anyone with an internet connection and some patience can too. The problem lies in the tiny 100 mb partition which exists as part of drive C. Many of the forums I've glanced at suggested deleting the 100 mb partition completely but then followed that up with scary things like...make sure you have a repair disc handy and prepare to use it up to 3 times! EEEEK screw that. Here's a fix that doesn't require a lot of time or computer savvy. Open your internet browser and look for Windows Partition Wizard, its freeware and only takes a second to download and instal. Once you open the program you'll see a list of all active drives on your computer. Highlight the 100 mb drive and in the menu above select EXTEND. A new window will open and will ask you which drive you want to take space from? Since its part of C, thats obviously where the space will be taken from. Then you'll see a slider in the middle of the window. Simply slide the bar to left to increase the size of 100 mb partition to whatever size you want. However, remember it just contains boot information so you clearly don't require it to be too big. I've read from other forums that you shouldn't extend it anymore than 500 mb so I chose the smallest increment the slider would allow. I moved the bar until the 100 mb partition was projected to be extended to 336mb. I then applied the changes and then a window opened telling me that the system would reboot and the wizard partition would make the desired changes. I held my breathe while the partition wizard did its job. After your computer boots, you'll see a screen from partition wizard that shows the progress. Once the task was completed and my computer booted again I checked disk management and that pesky 100 mb partition was now 336 mb. I immediately went to backup and restore and pressed the backup now button. TA DAH!!!! Backup without a hiccup. I can't stress enough how much of a computer dumb **** I am, so don't be intimidated. It took less than 15 minutes to complete the whole process.

sorry I thought that I had already responded to you. Your fix worked well for I used ( easeus partition master home edition (free) ) and thanks again Vern.

I tried your solution.  I only have English language pack installed.  Would a language pack be hidden?  Or, any other solutions?
