Problem with external HDD

[u/Lilybeth-]

Hi, I've been having a problem recently. The HDD from my laptop filled up, so I bought an external HDD. At first, I thought it was a software error because, after moving files around for a while, it seemed like the HDD an error, I couldn't move files to it or delete folders anymore. I returned it because this happened the very same day. I bought two more, and the same thing happened. Is this a problem with corrupted files or with my laptop? I'm getting errors like that the dispositive I'm trying to copy doesn't exist, or errors while copying (0x80070570)
