I wanted to make Windows 7 recognize my second hard drive. Following online instructions I went to control panel --> computer management --> storage. when the window opened it asked me what filetype the drive is. I accdentally/stupidly clicked CDFS. now storage manager sees the disk, but tells me it is unalocated, furthermore i have no access to it through the OS. I want to tell windows that my second drive is not CDFS, but all the tutorials i find online are telling me how to actually reformat drives- not what I want to do. interesting note: I restarted my computer with the drive unplugged from serial ribon, thinking maybe re-plugging would prompt windows to ask me for the filesystem again. My computer won't start w/o the secondary, backup, purley storage disk plugged in now! any help please?
