hi I am using a lenovo thinkpack running windows 7 pro and my system is set to run chkdsk every once and a while when i restart it. today it did it and it encountered a lot of errors it fixied, now normally this does not concern me but there were 3 things that jumped out at me this time, the first being that almost all the errors were in Index I$30 and i am wondering if that's normal, second for some reason it decided to run chdsk again and found even more errors in the same index and third that near the end i caught a glance at some error message that had something to do with bitspread and something that said it had been fixed. i just want to know if any of these are cause for concern thanks.
