I have found that when booting to the recover cd created in TI 10 (bld 4871) the system will not recognize an external usb cd/dvd burner or the internal cd/dvd burner. Both of these drives are recognized when booting normally and using the TI 10 installed in the system. If I go back and boot from the recover cd created using TI 9 everything works fine. I tried to create a second recover cd but got the same results. I contacted Acronis regarding this more than two week ago and never got a reply other than the automated response.
