Reformatted Windows vista, can't find 2nd hard drive


Dec 27, 2009
I just reformatted windows vista. My sata hard drive is fin (main hard drive and it's partition for data). however, my 2nd hard drive, EIDE I use for back up is not listed in my computer. I went to admin tools, and disk management and I see it there, and it shows HEALTHY. I right click it but on get HELP, not assign drive letters, etc. I have went to device manager and tried to disable, re-enable. uninstall it, reboot and have windows find it(which it does and it installs drivers) but I can't get it to be assigned a drive letter. Any help at all?
