I have Ghost 15 installed on an Emachine running Windows 7 Professional. The ghost program sees the C: drive and the USB target drive called "H" where the back up's go, but it does not see the 2nd internal sata drive or the other USB external drive. I have uninstalled Ghost and reinstalled it with no luck. Every drive can be seen in computer management with the correct drive letter. I have changed drive letters and even disconnected the internal sata and all USB drives with no changes. Any ideas. Thank you.
