I have recently installed a 160gb IBM Deskstar Hard Drive. It will only format in NTFS and loses 26gb in the process. Also everytime I restart I get an error message - error occured during installation of the device. One of the filter drivers for this device is invalid. I have tried the Microsoft Hotfix for this but to no avail. Why can't I use Fat32? Why am I losing 26gb when using NTFS? Why am I getting this error message and how do I get rid of it? Please help.
