The time has come for me to wipe the hard drive and re-install Windows 7 following a recent disastrous download that's effectively knocked out my Internet Explorer 11 and rendered Internet browsing difficult. My system has since become unstable and progressively slow and unfortunately, for some reason, I am unable to Restore to any previous installation. As I have loads of files I want to access, I've decided get a new Hard Disk and run the original H/drive (if possible) from a SATA drive Docking Station. So essentially, I would like to know if my Dell DXC061 will run and support a new Seagate 1Tb SATA3 7200rpm Barracuda. My BIOS is Ver. 2.4.0 dated 05/24/07. I have opened the CPU to see that the current drive connectors appear similar to those on the SATA Docking Station and think my old drive will fit it. However, it's now occurred to me that its possible the newSATA 3 drive may not be compatible with my BIOS or Motherboard. Any help or comments please? Incidentally I have most of my most useful files backed up on an external drive, so all, hopefully is not lost.
