I had been backing up my windows 10 for years to my wd passport. When i went to use it says error. Never really ever had a backup program work. I have used macrium reflect in the past it worked great. But I am getting older and things are becoming more diffeicult for me. However i still refuse to let someone do it for me. Spent my life working on pcs. Retired 10 years ago. Just a little out of touch. When I do a disk clone with Macrium reflect everything runs fine it completes copy. You can see data on the drive. However when I put the new drive in place of old it says device error repair device and it will not boot. I have even tried another drive. What am i missing here. Thinking of buying softwhere.
