Hi, Please could someone explain what the difference is between running a disc check from within windows ( From disc properties/tools etc ) and running sfc /scannow as a command prompt ? If a file problem is found where does the new file come from ? Does the scannow command check for bad sectors as well ? I have used scannow in the past, and as found by others it failed to complete stopping at 99% saying some files were incorrect but could not be repaired. This was apparently due to a windows update causing this, and in fact there never were any errors in the first place. Having run scannow for the first time since SP1 it now appears to complete 100% OK saying no violations found.
Hi, Thanks for replying, I'm still a bit confused over it! Are you saying the difference is that one tries to repair, and the other reinstalls the corrupt file. Where does it get from ? And does scannow log any bad sectors on the HD in the same way that running check disc from within windows does. I suppose what I am asking is if you feel the need to run a disc check which is the best option. Thanks
