External Hard Drive Not Working

I have a 2020 MacBook Pro Intel i5 and a Toshiba external hard drive from a few years ago. Unfortunately, for the past few weeks when I connect my external hard drive after about a minute and a half it disconnects by itself for no reason, and in the meantime I can't do any operation on the drive because everything freezes and then disconnects. I have already tried using First Aid but since after not even a minute it disconnects, First Aid itself cannot figure out the problem. I specify that I have already changed the cable and the USB ports are clean and have no problems. How can I solve this situation?

Sounds to me like the external drive has failed or is failing.

The resolve would be to replace the drive.

All new drives should be erased/formatted/initialized as new: GUID / APFS

Hi,

Just wonder if you or your friend have another Mac and connect Toshiba external drive to it if it mounts.
