just recently im getting the RSD prolbem but thats not all, today i went to backup the HD and it says i have ZERO space. i checked the last backup and it had only 37GBs and i know i didnt add any app or or anything 15GBs in only a few days. i used the app "whatsize" to compare my backup and HD and they are almost indentidcle in size. can someone tell me if they had this problem and way to solve this? thanks in advance!
