I ejected safely remove hardware in Windows 10 after When pulling the USB3.0 cable from the case + HDD2.5" to remove it from the PC my hand hit the HDD case and it moved on the table. Did this hit the read/write heads scratch the magnetic disks? my disks are 2013 WD10JPVX-08JC3T5 and HGST HTS541010A99E662 and Seagate ST500LM030
Any hard drive these days should automatically park the heads when power to the drive is lost, so I wouldn't worry about that.
the hdd case was just a few centimeters from the PC when I removed the USB3.0 cable from the PC it came out quickly and my hand hit the case but I don't know what the speed of the 2.5" hdds + usb3.0 case is after removing the cable
I suspect the drive should be ok, if you really want to be 100% sure copy all the data off to your PC. If you can successfully do that I wouldn't worry. Keep in mind always have backups of important data regardless.
