I've been using Robocopy for a while now and I have found it to be a simple and mostly efficient tool to mirror contents from one drive to another, and I've created a couple of batch files to simplify typing in parameters, like "AF ? ?" to copy my data files from one drive to another.
The thing is, for the last two days my data contents have been mirrored to my HDD partitions and a USB device absolutely fine - only a few files have been modified each time and I can rest assured that the contents are identical. The whole process has only taken a few moments.
But last night, the clocks went back and then earlier today I ran Robocopy once again to mirror my data contents. The HDD copy went without a hitch, but when running it to mirror contents to the USB device it started to recopy EVERYTHING over to it, naming all the files "Older"! What's more, I check the "modified" date/times on both sides and they're identical! I can only assume that the change in the clock from yesterday is the cause, and something unique to FAT32 file format (which the USB is).
The least I want to do is not to copy files with an older timestamp on top of new ones (if that's what's happening) so is there a way I can still use /MIR and use the /XO (exclude older) switch as well?
