I did another extreme test with FDISR & ATI, this time with 10 snapshots. Partition [C:] = 29,2 GB Number of snapshots = 10, which is the maximum of bootable snapshots in FDISR. I used the Acronis Rescue CD for restoration, which is exceptional for me. I used my external USB 2.0 harddisk. Good news 1. Can you entrust ONE snapshot to ATI ? NO, you can NOT, because only a fool would work with ONE snapshot in FDISR. 2. Can you entrust MORE THAN ONE snapshot to ATI ? YES, you can. 3. Can you entrust TEN snapshots to ATI ? YES, you can. 4. Did my computer show the FDISR Pre-boot Screen right after restoration ? YES, it did + F1-key. 5. Did my computer booted in the supposed snapshot without using the F1-key ? YES, it did. 6. Did I disable or enable the Pre-boot in FDISR before or after the restoration ? NO, I didn't, because it isn't necessary. 7. Did I have any problems with the MBR ? No, I didn't. 8. Did I restore the MBR with ATI ? Of course I did. Bad news 1. Can you trust the estimated restoration time of ATI ? NO, you can NOT. ATI estimated 120 minutes = 2 hours and the real time was 145 minutes = 2 hours 25 minutes. 2. How long took the verification ? 73 minutes, too long for a verification, it takes normally 13 minutes without CD. 3. How long took the restoration ? 72 minutes. a bit long, but bearable. Conclusion Although you can entrust FDISR to ATI, it takes a long time to get that feeling. A newbie in my situation would live in 145 minutes of FEAR and DESPAIR, which is quite a mental torture. I hope my test will minimize the fear/despair and keep users in a healthy state of mind during the restoration.
