I've had TI 9.0 about a year. It's always made backups as easy as pie, and has always been flawless recovering a few files from within the program running on WinXP that were accidently deleted and eventually removed from the recycle bin. I've thought it was an excellent application until tonight. My wife got a trojan downloader (thus many more viruses) on her laptop that I couldn't remove without extreme measures, so I decided to finally use the program for it's true purpose, or for what I bought it for anyway, to restore a complete hard drive from a backup. With the recovery disk in hand, it should have been a simple 1-2-3 step process. But nooooo! After getting verified backup files every time I made backups, I found tonight that all of my backups were either invalid files or were corrupted. I got on the internet and read all evening. Almost everything I've read said that it's my computer's fault...bad memory, bad PSU, bad this, bad that, bad the other. I couldn't believe it was our computer, but I couldn't prove it because I couldn't even boot back into WinXP. Her laptop is the only WinXP computer left in the house. Two others are running Ubuntu Linux (great OS!) and one of them is dual booting Vista, which locked up when I tried to install 9.0 to see if it would read my external drive's backup files. I found only a small handful of people that said this is a problem with the Acronis backup disk, and that Acronis wouldn't or couldn't fix it. I decided to download the trial version of TI 11.0 and install it on the Vista machine and create a new recovery disk. With the new disk in hand, I booted the wife's laptop. It instantly recognized the .tib files and I started my recovery. It is currently about 50% into a complete disk recovery and still chugging along. Personally, I think this (or preferably a more concise version) should be a sticky for the folks with 9.0, with TI9.0 and corrupted files in the title. I'm sure it's in more than one thread, but that stuff gets buried and the search feature is worthless when it maxes out at 1000 hits on corrupted files. Folks that have 9.0 should give this a try before fooling with memory tests, buying new high end ECC ram, swapping PSU's, etc. It's worth a shot. I was lucky and had more than one computer capable of going online to research and download the trial TI 11.0 and fix my problem. I feel sorry for those who only had one computer and purchased the bugged 9.0 and lost all their precious data. Do I like the product? I love how easily it backs up and restores files while running in Windows. I hate that once Windows gets toasted that the recovery disk is a complete failure (the 9.0 disk). Will I keep using Acronis TI? I've paid for it, so if the recovery finishes tonight and her computer gets going again, I will. If it doesn't complete the recovery, I'll switch to Ghost or just buy the biggest external drive I can find and do a straight disk image and forget about backup software all together.
