I have a spare SATA hard drive hooked up to use as a backup medium for my primary Windows drive, this is the drives only purpose. In the BIOS, the Windows drive is set as first priority, but if I try to boot with the backup drive, it gives a disk read error Right after POST and to restart the system.
If I disconnect the backup drive and boot into Windows 7, THEN connect the drive, it shows up and functions just fine, I can even set the computer to sleep or hibernate and it will resume normally with the drive attached. Have already tried switching all drive SATA ports. All drives pass diagnostic tests and return that SMART is functioning correctly, so I am at a loss of what's going on, it's pretty inconvenient to have to disconnect the drive any time a full reboot is required
