I have new computer with Vista os. I backed up data only to 2 dvds successfully using ATI 10. When I try to reinstall data from the dvd ATI will not recognise the removable drive. My Computer and my file manager programme recognises the drive and the contents as MyBackup2.tib but ATI will not recognise the drive. Installed latest build update and backed up again successfully to new dvds but still AT10 will not recognise removable drive but does recognise other hard drives. I have no problem with backing up and restoring the operating system to another hard drive. Any suggestions please.
