Ipad ios 4.2 Problem (21)

So i synced my ipad to my computer and at first it wouldn't update to ios 4.2 but i eventually got it to update. i then started to organize all my apps into folders and i was playing with the multitasking when it showed the itunes logo and the usb cord telling me to sync the ipad like it had when i first bought it.
so i tried to sync it and it would say that it had found a ipad in recovery mode and that i must restore it before i could sync it. so i clicked ok and clicked restore. it then asked me if i was shure that i want to restore factory settings and that all my media and other data would be erased. i clicked restore and update because i had just backed up all my stuff on my computer. it then show that it is extracting the software and when it is done it says that it is verifying the restart with apple. then an error pops up and says that the ipad could not be restored because of an unknown error and it shows (21). i've tried restarting my computer and it still wont sync. PLEASE HELP!!!!!

i too had this problem. the loading bar kept partially completing itself and never finishing so, after turning off by pressing the sleep button and home button together and holding. finally, i unplugged the unit from the mac, let it partly do 'its thing' and then forced a shut down then, re plugged it in and when it turned itself on upon connection to the computer, it seems to work fine. so far so good anyways! good luck folks
