Why Does My Hard Drive Show up as Removable

First we'd like to tell you the reason why you see the internal hard drive shown as a removable disk. Whether the device is considered a removable device depends on the system's BIOS and how the various SATA ports on the motherboard are marked. The inbox driver directly checks SATA port and treats the device connected to the port marked "external" as a removable device. Not all storage drivers do this, which can be a potential cause of corruption or data loss.

How to Fix Internal Hard Drive Shows as Removable in Windows 10

Here on this page, we find 2 most applied solutions for you to troubleshoot the problem without a hitch. let's begin with the simple method, but most of the time, it's helpful.

Solution 1. Modify in Device Manager

Step 1. Type Control Panel in the search box next to the Windows menu in Windows 10 and open Control Panel.

Step 2. Navigate to "Device Manager".

Step 3. On the Device Manager window, double-click on the "Disk drives".

Step 4. Right-click on the internal hard drive (HDD or SSD) and select "Properties".

Step 5. Under the Policies tab, make sure "write caching on the device" is enabled, there is no "optimize for quick removal" enabled. This is directly related to how Windows considered or not a drive is removable.

Step 6. Update to the latest chipset and AHCI/RAID driver.

Solution 2. Modify in Registry

Since the problem cannot be ideally solved by the simple method, you have to rely on the last resort which ensures a high success rate. Only one noticeable point. This is a Registry fix, so it's somewhat risky. You should always BACKUP the registry before you make changes.

Backup registry and system in advance

Customiztion settings like enabling an automatic backup schedule in daily, weekly, monthly, or upon an event, and making a differential and incremental backup are available in the Options button if you're interested.

reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device" /f /v TreatAsInternalPort /t REG_MULTI_SZ /d x
