Thank you so much to both redcrown and EB-1. I guess as you both say that the files became corrupted during one of the transfers, but not the last one since I'm using brand new hardware, including cables and computer (only the hard drives are older). Still, it was my belief that once a digital file became corrupted and the 1's and 0's got even slightly mixed up, the file would become impossible to open and when carrying out the transfer, any errors would trigger an immediate alarm in the windows program stating something like "cannot read-write" or something similar. Anyway I'm just a user with very little knowledge about how computers work, so I can only say that it is all new information to me and that from now on I will have to keep an eye on yet another one of "those things".
I'm afraid I cannot check the state of any of the originally backed up files since I immediately formatted the old drives to put them as available new space. Still and as I mentioned in my request, the photos where not that important, so the loss is minimum.
But it is clear that from now on I will take greater care when I'm backing up my files; not only in warming up the drives and checking cables and so on, but something I'm sure it also affects the correct trnsfer of big files and that is NEVER believe that Windows, even in its latest version is multitask, so when the files are being transfered, instead of checking my email, or continue using Photoshop, I will go & grab a cup of coffee or something, just so I leave the mouse and keyboard alone...
I would however like to know (just for the heck of it), what kind of corruption is present on those files, that creates those tone and split-like changes on the picture..
