My Backups Are Always Corrupt.

Thread needs solution

Everytime I attempt to backup my computer which is freshly installed windows 7 64bit, it succedds however when I recover or validate it always says the image is corrupt.  I never tamper with the backups so how do they get corrupt?

I am backing up to an external hard drive and also attempting recover from it as well.

WEll, maybe they are and maybe they aren't.  When ATI tells you a backup is corrupt what it's really saying is, When I read this file and generate error corrections codes, I get dif values than the ones I got when I created the file.

IF you are using av ersion earlier than ATI 13/2010, then iirc, vlaidation won't work under w7 -- and ATI 13/2010 has some probs too with this.

So the problem could be in the reading (and the file is perfectly fine) or it could be inthe original writing (and the file is junk) or both. But assuming those things are at play then the likely suspects: if the prob only shows up when trying to valideate or restore with the bootCED, then it's most liekly a problem with the hardware drivers on the BootCD and Acronis needs to provide you with an iso for a diff bootCD.  IF the problem happens even if you create the backup and try to validate within win, then you might need to run memtest overnight to ensure that you don't have any intermittent memory in the farter reaches of the memory.

Also, if you haven't already, why not run chdks /r for the heck of it just to rule out any file system probs on the target disks?
