A friend of mine brought me a fujitsu siemens laptop (amilo pro) with a Samsung Sata HM060II hard drive that was not logging into windows xp. I ve put it into a usb case and run a virus scan on it that cleared the virus and the disk was working properly. When i logged in windows i ve notice so many spyware that i tried to format the drive immediately.On my friends laptop the win xp installation disk wouldnt recognise any hard disks so i ve tried installing it on the drive as an external usb drive from my laptop.The installation failed with a blue screen for hardware failure. I bought a new hard drive (Samsung SATA HM160HI) that i partitioned and formatted. ( primary, NTFS). Neither XP or Windows 7 installation recognize it. i can work on it from my laptop as an external usb drive. i ve run several diagnostic tools from my friends laptop with a boot cd and every software recognize it, give me details, scan it for errors. The bios even recognize it. I need to install an OS on it! any ideas or suggestions? i ve been working for a week on it. its getting exhausting.
