I discovered a way that ensures I no longer get FRAGMENTATION ERROR:
First off I want to note that my ROMs were never the issue, nor was the brand of my micro SD card.
All I had to do was simply copy my ROMs over one by one, and the problem went away. When I copied two or more to the card, I would get the FRAGMENTATION ERROR on most of the ROMs.
Hope this helps someone.
I copied all of them at once but I used a program called Teracopy and I didn't have any issues. That is another thing people could try.
