External hard drive keeps disconnecting then reconnecting

Hi
for no obvious reason my transcend store jet 25M3 1TB suddenly started on disconnecting and right away reconnecting
but only from my front USB3 port (p.s. i have another external HDD exactly the same just a drop more new that i can't decide if it also has the problem but if it does for sure not at the extend of the first one)
what i already did
i already disabled the USB power settings
downloaded the latest USB3 drivers
installed the latest firmware for the hard drive
it's the same PC as my specs
what could i do
thanks

well right now it's plugged in in another port and works perfectly fine but i know from experience that it might suddenly start again to disconnect and reconnect but not on the rate like yesterday
i used that port that it kept on happening a lot of times with a bunch of other devices even with the same device but it never happened before
i used a different cable a newer one as i wrote i have two of the same external HDD's the problem was with the old one but i used the cable of the newer one (the older cable had a cable that from the USB port there came out another thin cable with another USB port but the new one was a simple cable)
it happens suddenly either when idle either in the middle of working with it
which software should i use to check the drives health?
thanks

this is what i got

thanks
