Bought an Hitach Deskstar Drive (Model:HDS728080PLAT20) about 2 months ago and have been using it as a master slave on Windows XP. Then decided to re-install XP as well as put Service Pack 2 on it. Also got the latest BIOS update for my computer. Now that XP SP2 has been put on my machine I am unable to explore the drive as the following error is displayed "Unaccessible. File or directory corrupt". I then deleted the partition and tried to format the drive as NTFS but got to 99% completion then failed implying data was RAW and was unformatable. Have tried formatting in DOS as well as Computer Management but have been unsuccessful. However once the drive is connected to Windows 2000, or XP without SP2, I am able to format and use the drive. Also ran an advanced 'Drive Fitness Test' that found no errors. Therefore was wondering if this was a common problem and whether anyone :hotbounce could offer me any advice of how to get the drive working with SP2? I would greatly appreciate your help.
