Access to internal SATA disks is denied or limited to read-only access

DESCRIPTION

Access to internal SATA disks is denied or limited to read-only access because of DeviceLock "Removable" permissions restrictions.

COMMENTS

In most cases, the operating system treats any internal hard drives as devices of Removable type if they support the hot plug feature (the "Safely Remove Hardware" function is enabled for them).

There are several ways to determine if this is the case:
- Checkfor the "Safely Remove Hardware" option in the system tray for the affected SATA drives;
- Run Regedit to locate your SATA disks key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE\..\..], and find 'Capabilities' parameter to have '0x00000004' value.

The root cause of the problem is the SATA driver incorrectly determined that your internal SATA port is external.

RECOMMENDATIONS

SATA_removable.reg (820 b)

Please import attached Reg-key on problem computer(s) to disable detection of SATA drives as removable.

If you have an NVIDIA chipset, the following registry edit should work for you:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvata]
"DisableRemovable"=dword:00000001.
