python
import psutil

def check_disk_errors():
partitions = psutil.disk_partitions()
for partition in partitions:
try:
partition_usage = psutil.disk_usage(partition.mountpoint)
if partition_usage.total == 0:
print(f"Disk error on {partition.device}")
else:
print(f"Disk is healthy on {partition.device}")
except Exception as e:
print(f"Error checking disk: {str(e)}")

check_disk_errors()


In this code, we import the `psutil` library, which provides an interface to retrieve system information. We define a function `check_disk_errors()` that iterates over all disk partitions and uses `psutil.disk_usage()` to check the disk’s total size. If the total size is 0, it indicates a disk error, and the corresponding message is printed. Otherwise, it prints that the disk is healthy.

Please note that this code only checks the disk usage and not specific error codes or messages related to non-system disk errors. To handle more specific disk errors, you might need to explore additional Windows APIs or error handling techniques.

Checking IDE or SATA Cable Connection

To check the IDE or SATA cable connection on your Windows 10 computer and fix the non-system disk error, follow these steps:

1. Shut down your computer and unplug it from the power source.
2. Open your computer’s case and locate the IDE or SATA cables connected to your hard drive.
3. Ensure that the cables are securely connected to both the motherboard and the hard drive.
4. If any cables appear loose or damaged, replace them with new ones.
5. After replacing or ensuring the cables are properly connected, close your computer’s case and reconnect the power source.
6. Start your computer and press any key when prompted to boot from a non-system disk.
7. If you still encounter the non-system disk error or a black screen, it may indicate a different issue. Consider seeking further assistance from a professional or referring to other solutions in this article.
