Some years ago on my first computer my HD crashed and I lost some data. Since then I have sought to ensure all data is backed up on a regular basis. More recently and on my latest computer I had acquired lots of data/programs. In addition to all the family photographs, I had put on a number of home videos. Previously I had backed up the key data to DVD but the sheer size of the data now made that difficult. Accordingly, I surfed the web and read computer magazine reviews which led me to buy TI9. At the same time I bought an external USB HDD. I particularly liked the thought of imaging the entire disk so I would not have to reinstall non essential data (such as games etc) if there was a crash. As with many people, I am not really a computer expert and was attracted by what seemed to be the ease of use and reliability of the product. Anyway, I installed the software, created the emergency disk and then proceeded to create a full image of my c drive. I have 2 200gb HDs in RAID 0 and the total image was of some 170GB. I was pleased that the software provided for verification, and it indicated that the image was fine. About 3 weeks ago my graphics card failed. The system was RMAd and it was discovered that the o/s had also been corrupted. Thats not the end of the world I thought as I have the complete image. The system was returned earlier this week with HDDs refomatted and with windows Xp installed. First thing I do is to install TI9, plug in the external HDD and seek to recover the latest differential which I had made just before the crash and which had been verified. I do not seek to verify before installation as I perceive that will take time and, in any event, I have just recently verified it. 12 hours or so later the message comes up that the image is corrupted. I try to recover the full image without differential and again the image is corrupted. Not only that, but the process has in the meantime wiped the c drive so I no longer have any working system at all. I am currently trying to proceed by reinstall all the files and folders (through booting from the recovery disk) which looks like it is going to take 24 hours. I dont know if this will restore the operating system and perhaps soemone would be kind enough to tell me whether it could work in principle. If this doesnt work, i intend to try to reinstall windows through the recovery disk (last time I tried it said it could not find a HD) and then install files/folders individually in the hope that some are not corrupt. Any thoughts on this would be most appreciated. It is a real shame that I did not find these forums before which seem to confirm my experience that the product appears to be defective. What particularly annoys me (and yes I am annoyed) is that I verified the image. I now read, and my experience demonstrates, that this facility is not accurate. Any thoughts generally on what I should do (before going to a disk recovery company) would be appreciated. I should add for the sake of completeness taht I do have a wireless mouse which I note someone has suggested may be a reason for these issues.
