Had a hard drive crash (I think), very little noise, will not boot, gets to Windows copyright screen and hangs up (Windows Vista, been running about two years). SO for immediate repair I install a Seagate Barracuda 500GB SATA drive. Original is Hitachi 320 GB SATA drive. Computer is a Gateway desktop, not sure of MB specs. Anyhow, new install went well, reinstalled OS and boots fine. However, I would like to reconnect the old drive and see if I can salvage any files, but when I reconnect the original drive it reverts back to not booting past the Windows copyright. I have tried changing the order of the SATA cables, the boot order, etc, but nothing has worked. Is there someway I can set it so that the original HD can be seen, but not booted? Appreciate any help
