I gave my uncle a 120 GB Samsung 840 from my daughters PC. It had the O/S(Winows 7) installed on it. Anyway I do not think I erased the disk before I gave it to him. When he installed it in his PC he attempted to initialize then format it but it keeps coming up in RAW format. I then deleted simple volume and again attempted a reformat in NTFS file sysytem and again it says "check connection" and it still is in RAW format. I need to get it to format to NTFS so he can use it. Can't figure out what is wrong. I can use Team Viewer to remote in to him but I think it may be a BIOS setting and that I cannot check for him. Any ideas much appreciated. I'm thinking it has something to do with my daughters O/S still being on it. Thanks
