How to get PhysicalDisk without using WMI in Python?

I would like to get the Physical Disk. One of the information that I need is BusType. I would like to to find it without using WMI. Is there any way to do that?

Thank you for the advice and information.

You can get bus type of physical disk with powershell:

Ref: https://www.action1.com/kb/getting-PC-hard-drive-information-using-Powershell.html

Get-PhysicalDisk

output:

Number FriendlyName        SerialNumber                             MediaType CanPool OperationalStatus HealthStatus Usage            Size
------ ------------        ------------                             --------- ------- ----------------- ------------ -----            ----
0      INTEL SSDPEKNW512G8 0000_0000_0100_0000_E4D2_XXXX_XXXX_XXXX. SSD       False   OK                Healthy      Auto-Select 476.94 GB

To get bus type:

Get-PhysicalDisk | ft -AutoSize DeviceId,Model,MediaType,BusType,Size

output:

DeviceId Model               MediaType BusType         Size
-------- -----               --------- -------         ----
0        INTEL SSDPEKNW512G8 SSD       NVMe    512110190592

To call powershell from python:

Ref: https://www.phillipsj.net/posts/executing-powershell-from-python/

completed = subprocess.run(["powershell", "-Command", "Get-PhysicalDisk | ft -AutoSize DeviceId,Model,MediaType,BusType,Size"], capture_output=True)

example:

C:\Users\XXXXXX>python3
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> ps_command = "Get-PhysicalDisk | ft -AutoSize DeviceId,Model,MediaType,BusType,Size"
>>> completed = subprocess.run(["powershell", "-Command", ps_command], capture_output=True)
>>> print(completed)
CompletedProcess(args=['powershell', '-Command', 'Get-PhysicalDisk | ft -AutoSize DeviceId,Model,MediaType,BusType,Size'], returncode=0, stdout=b'\r\nDeviceId Model               MediaType BusType         Size\r\n-------- -----               --------- -------         ----\r\n0        INTEL SSDPEKNW512G8 SSD       NVMe    512110190592\r\n\r\n\r\n', stderr=b'')
>>>

Therefore you can make such script:


# get_disk_bustype.py
import subprocess
ps_command = "Get-PhysicalDisk | ft -AutoSize BusType"

run_result = subprocess.run(["powershell", "-Command", ps_command], capture_output=True)
print(run_result)
# CompletedProcess(args=['powershell', '-Command', 'Get-PhysicalDisk | ft -AutoSize BusType'], returncode=0, stdout=b'\r\nBusType\r\n-------\r\nNVMe   \r\n\r\n\r\n', stderr=b'')

run_result_stdout = str(run_result.stdout)
print(run_result_stdout)
# '\r\nBusType\r\n-------\r\nNVMe   \r\n\r\n\r\n'

run_result_stdout_bustype = run_result_stdout.split("\\r\\n")[3]
print(run_result_stdout_bustype)
# '0        NVMe   '

run_result_stdout_bustype_clean = run_result_stdout_bustype.strip(" ")
print(run_result_stdout_bustype_clean)
# 'NVMe'

output:

C:\Users\XXXXX>python3 get_disk_bustype.py
CompletedProcess(args=['powershell', '-Command', 'Get-PhysicalDisk | ft -AutoSize BusType'], returncode=0, stdout=b'\r\nBusType\r\n-------\r\nNVMe   \r\n\r\n\r\n', stderr=b'')
b'\r\nBusType\r\n-------\r\nNVMe   \r\n\r\n\r\n'
NVMe
NVMe
