I have a Snow Leopard with a case-insensitive file system. I wonder is there a way to convert the FS to case-sensitive without having to format and then reinstall the whole OS. In Linux there are utils like parted that enable to change the partition FS (at least ext2 to ext3 for one), is there something similar for Mac OS X. I mean that case-sensitivity seems to be a small option to change, does it absolutely require a format+reinstall of hd?
I've done several attempts to establish SSH-connecton for user root@host using putty terminal. While doing so I specified wrong credentials several times and after that I've specified them correctly, and then after the credentials were accepted the ssh session breaks with
"Server unexpectedly closed network connection".
This error is reported by putty terminal. When trying to ssh root@localhost from the local console - it works fine. It also works fine when I ssh otheruser@host from other host. So network connectivity issues are not guilty. The only error I am thinking of is: "Too many Authentication Failures for user root" although putty reported a different error.
The question is: how to recover from this error condition and let putty login again? Restarting sshd seems to not help
