I can't seem to find an answer to my question on my own. I have a NAS542 with four hard drives of differing capacities, set up as JBOD, no RAID whatsoever. I have a spare large-capacity hard drive I'd like to insert into the above NAS, and I want it to hold the files contained in the previous hard drive. My OS is Windows 10. Do I simply insert the new drive in place of the old, let the NAS initialize it, then copy the contents of the replaced drive onto the new one? IIRC, Windows won't recognize the contents of UNIX-based drives, so that could/would be a problem? Does cloning do the trick, because it basically just copies one drive's contents onto another, regardless of file system and disk contents? If so, should the cloning be done BEFORE inserting the larger disk? Does Windows have built-in cloning capabilities and, if not, what's the best/easiest way to clone hard drives without having to buy software with a large install footprint? Thanks in advance for your help!

When I had to do similar disk-swap before I bought the current one I replicated the old drives to temp. storage (External USB) with a pretty simple RoboCopy script so all time/date stamps were preserved. No additional SW required but it as quite slow process . On the other hand it' all free and You can customize copy/sync options very detailed and get a good log of progress.

If for any help; this is how the command-line looks. (prerequisites that Source is mounted as "S:" and Target is mounted as "T:" ROBOCOPY S:\ T:\ /E /MIR /COPY:DAT /DCOPY:DAT /MT:8 /NP /LOG:SyncLog.txt

I'm not sure that's the correct or even possible way... (BTW: RoboCopy should be available on all Win10 releases as command-line tool.) I used an external USB drive as temp. storage; 1. Backup to external drive with RoboCopy 2. Swap disk 3. Restore back from USB with RoboCopy
