    I got a macbook pro 13.3 2017. 16gb ram.
    Now its my first external hdd this thing happens and this is getting annoying.
    If someone moves an externall hdd while its connecting a macbook it throws an error, but after some update the disk becomes and unusable. I cant mounti, i cant use, gotta go to windows pc and do the error checking.
    After that some of the files are deleted.

    I am a photographer and this thing is getting pain in the ass.

    Anyway to be able to get around or fix it? Maybe there some errors in macbooks software?
    Should I send my macbook pro to the support?

    What format is your external HDD?

    Do you eject the disk properly after use or do your forcefully remove it when the disk is in use?

    Generally data goes missing because of three possible reasons:
    - the external is failing
    - the volume is corrupted
    - you are manually deleting data yourself - accidental or not.

    Possibly the volume is not mounting due to the OS trying to the repair the drive or is stuck repairing the drive, you can force quit "fsck" from within activity monitor to see if the drive will mount. If yes, that would confirm that the volume on the external is corrupted.

    I would upgrade your MacBook Pro to the latest OS. Scan for adware or malware. Backup and reformat your external HDD so there is no corruption, maybe run a first aid using disk utility. Educate yourself on how to remove a drive safely to prevent volume corruption.

    the problem is just a little movement of disk and error occurs.
    For example I repaired it on windows and no files are shown.
    But the amount of exhdd used is similar before the error.
    Also somehow i only see some of the files on the disk.

    I always eject the disks in away it should be. Never try to do it forcefully

    Sounds to me like either your disk is failing or maybe a cable/port is defective. Is it a single HDD or did you observe it with multiple different ones?

    Mechanical drives have moving read/write heads and these drives should not be moved while powered up or connected to any computer.

    It could be a bad cable or drives as previously mentioned but it could also be an issue with the port or ports on the Macbook.

    See if you can access the SMART codes for the drive, that's where I'd start.

    If the drive unmounts by moving it (even a little)...
    Could be a bad cable or port. Loose connection?

    One important warning about external drives (if you didn't know already).
    DO NOT just "unplug" an external drive unless you drag its icon to the trash first, and let it "unmount".
    This can be particularly troublesome with USB drives.

    This is a chronic problem with my boss's old MBP. The loose connection is on the computer; all 3 USB ports are the same. It happens with different drives and different cables. The 3 ports on the MBP seam to have "worn out". They don't seem to grip the USB plug as tightly an most other USB ports on other machines. There could also be damaged soldier joints between the USB jacks and the motherboard, but I think it is the loose jacks that is the root cause.
