I bought some used drives from Server Part Deals, did a full verify test with Victoria and got no errors. Those drives as well as another one I already had are 12tb and I wanted to copy a nearly full old one onto one from SPD. I only have a laptop so I’m limited to USB speed when copying the nearly full one on to an empty used one.
The first time I tried copying I just used windows explorer and it failed after about 200GB. Transfer speed was 0 and I ended up having to cut power to the drive. The second time I used Tera Copy and it failed after about 600GB because the drive was no longer visible/accessible to the PC.
I removed the drive from the Orico enclosure and put it into an Ugreen one. Although it hasn’t finished copying, it’s about 2/3s of the way through without apparent problem. So should I just assume the Orico enclosure is the problem and throw it away?
