Advertisements I have a 1TB drive that was previously formatted through Windows Disk Management. When i try to use WinMFS to restore a backup to that drive, WinMFS crashes. In the WinMFS site i noticed that it said NOT to use Disk Management to format a drive. So, it is formatted in NTFS. Hopefully, this is why WinMFS is crashing. Can someone tell me the proper way to format a Disk for use in a TivoHD? I'm posting here because I am not getting a response on the MFSLive site. Thanks for your help.
