I'm not very experienced with PC hardware, so I'm trying to figure out what's happening with my 8TB Seagate hard drive (ST8000VN004-2M2101). It used to work normally, but recently a game download would stall and then the drive would disappear or become impossible to open in File Explorer. During the problem, Task Manager showed 100% active time, almost no transfer speed, and response times jumping from 0 ms to 28,000–70,000 ms. Parts of Windows, including File Explorer and Task Manager, would freeze, although web browsers continued working. I had to shut down the computer to recover. I wiped the drive, so it currently contains no important data and has about 7 TB free, but the same behavior makes downloading games impossible. A SMART check reported the drive as healthy. Is there anything I should troubleshoot, or should I replace the drive?

A single SMART result that says “healthy” isn’t enough to clear the disk. Post the complete SMART attribute values rather than only the overall status, and check the drive’s additional health or FARM data with a tool such as smartmontools. Pay particular attention to read errors, pending or uncorrectable sectors, interface errors, and command timeouts. If the full diagnostics show problems or the drive repeatedly locks up, use the warranty and replace it instead of continuing to stress it.
There usually isn’t a practical repair for a hard drive that hangs for tens of seconds or minutes and causes Windows to freeze. Since the disk is empty, you can test it with the manufacturer’s bootable extended test after checking the cables. If it fails, or if another cable and port make no difference, retire the drive. If it passes but still causes these symptoms, replacing it is still the safest option because intermittent failures can worsen without warning.
Those symptoms strongly suggest a drive, connection, or controller problem. A drive can report a healthy general SMART status while still having very slow reads, timeouts, or other issues. First, back up anything important and avoid relying on this disk. Check the SATA data and power cables, try different ports or cables, and run the manufacturer’s extended diagnostic test. If the behavior continues, replace the drive, especially if it is still under warranty.
I was hoping to avoid replacing it, but based on the extreme response times and freezing, does this sound more like a failing drive than a Windows or download problem?
