2.5" HDD + USB/SATA adapter on the front port of the PC

I performed a surface scan with HD Tune without red blocks. After the test, and using the PC, the same HDD disconnected and reconnected a few times with the Windows 10 sound. This disconnection (eject) followed by connection causes bad sectors (badblocks) on the HDD. Is a new 3-hour surface scan necessary to check if the HDD has been damaged?

Before this event the surface test found no damaged blocks after this event sometimes automatically disconnects/reconnects the HDD will a new surface test of many hours be necessary to check if there was any problem or if it generated bad blocks and bad sectors?
