    hi I was just getting a backup from my new macbook pro but I accidently unplugged my external hard drive while it was transferring data. I freaked out . then a window came up indicating that "disk not ejected properly". but when i restarted and connected the external drive again; everything was working fine. do you think is there any possibility of hardware damage (to computer or external drive) ;or the only danger is data corruption ?? thanks in advance

    The danger is data corruption as stated but to be honest that hasn't really been an issue for a decade this seems to be a legacy from older systems where this really could be an issue that Apple have never removed.

    What hasn't been an issue? Unplugging a drive while data being written to it is absolutely a data corruption issue.

    Hardware damage? No. Data corruption? Absolutely!

    Just re-write everything you were currently writing to the external disk, and you'll be fine.

    Data corruption- like stated above - re-write and then eject properly
    Should be fine after that

    If everthing is still working ok, don't worry over it.
    Run Disk Utility's "repair disk" function on the external drive, just to be sure.

    Additionally, recommended programming processes of using temporary files for saves, then moving them into place once the write is completed.

    It can still happen, but it's not the issue it used to be.

    Hardware likely OKAY. Data should be considered corrupt -- retransfer.
