Well if you can get hacked and your USB mem stick is unplugged from ya rig, than ya wallet is safe...
So yes Mem-stick is safer...
Thats just the wallet.dat as backup not for using other things...

Well the thing is...
I downloaded the latest bitcoin wallet, and comes upt with a warning about "Displayed transaction may not be cottect, you may need to upgrade, or other nodes may need to upgrades.

I do have another partition on my harddrive that have plenty of space... how to re-direct it?

btw im running on XP

My harddisk getting full, annd yes i backed up my wallet.dat on my Mem-stick..

Is there a way to clean my bitcoin files and re-scan the blocks again?

thank you for helping me out
