Example: (This is based on the path displayed on your computer)
The device instance path is:
PCI\VEN_15AD&DEV_07E0&SUBSYS_07E015AD&REV_004&BBF9765&0&2088
Path 1 is: VEN_15AD&DEV_07E0&SUBSYS_07E015AD&REV_00
Path 2 is: 4&BBF9765&0&2088
After recording these two paths, you can close the Device Manager window first.
You must now modify the registry key associated with this AHCI standard controller.
Step1. Press Windows key + R key, type "regedit" and press Enter.
Notices:
Registry Editor is the most sensitive part of the system. Before you modify/delete registry keys, we recommend backing up the registry on your computer.
Step2. With the Registry Editor open, select the File item. Then select "Export" to make a new backup on your computer.
Step3. On the left, expand in this way:
HKEY_LOCAL_MACHINE > System > CurrentControlSet > Enum > PCI > Path1（Path 1 recorded above）> Path2（Path 2 recorded above）> Device Parameters > Interrupt Management > MessageSignaledInterruptProperties
Step4. Now, on the right, double click on the "MSISupported" to edit it.
Step5. Then, after setting the value to "0", select "OK".
Close the Registry Editor window when the settings are complete. Restart your computer to save this change. This should stop disk usage issues on the system.
Doing any setting may encounter some problems that cause the system to fail to start, remember to make backups of important files!
