Right I usually keep my profile on my HDD and never have any problems with my profile corrupting, then I transfer my profile to a Memory Unit or USB drive and take it to a friends and use my profile on their 360 and play a few games on there, when I return I put the memory unit/USB drive in my 360 to transfer it back and its corrupted and yet when if I were to put it back in my friends 360 my profile isn't corrupted???
I know I can recover my profile but believe me having to recover a big profile like mine takes a good 2 - 3 hours and it gets very annoying having to do that every single time!!
Have XBL changed something as I never had this problem in the past?
