Hi, I recently cloned a hard drive with 400GB of data from sata to ide and it took 2 hours to do it with ATI 10 (BUILD 4940). Now I tried to clone it back again to the sata hard drive from ide, and it took +12 hours!!! sata hard drive is 7200rpm configured @ udma5 (no udma6 is available with this drive) ide hard drive is 7200rpm ata 100, udma5 too, with the latest chipset drivers installed from Intel. the ide hard drive is connected alone on the primary ide port. (no slave cdrom) the bios and the intel application acccelerator shows the ide hard drive using 80 cable type and udma5 mode enabled no antivirus running tried this tweak with no results: http://support.microsoft.com/kb/247951/en-us i have no idea what is causing this poblem. thanks in advance for your answers. regards, alex.
