STG_E_RESETS_EXHAUSTED
DVD drive region-change allowance is exhausted or fixed
STG_E_RESETS_EXHAUSTED is HRESULT 2147681035 (0x8003030B) from winerror.h. The documented description is “Copy Protection Error - The drive's region setting may be permanent or the number of user resets has been exhausted.” The result belongs to reading or changing RPC region information for a DVD drive. Interpret this result at the native boundary before a wrapper hides the condition that the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent.
STG_E_RESETS_EXHAUSTED means that the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent.
Where the result appears
- This result can surface in a DVD CSS authentication, key exchange, protected-sector reading, or region-management logic.
- Map the failure to one concrete operation among IOCTL_DVD_READ_KEY, DVD_COPY_PROTECT_KEY, AGID allocation, challenge and bus keys, title offsets, and region data.
- Preserve physical drive identity, media ID, region state, AGID or session generation, key type, title offset, sector range, and driver stack before releasing or replacing the object that returned this result.
An incident record must distinguish caller, runtime, provider, and backing resource while testing whether the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent.
Typical causes and interpretation
The immediate contract boundary is specific: the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent. Common cause branches include the following:
- All allowed user region changes were consumed.
- The drive firmware exposes a fixed region.
- Management software attempted an unsupported region update.
Confirm the cause branch that explains why the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent by using call arguments, object state, metadata, device information, or provider traces.
Correct handling and recovery
Do not repeat region-setting requests. Report the permanent device state and use compliant hardware or media. The failure report should capture the relevant state during reading or changing RPC region information for a DVD drive so it is clear why the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent.
A UI loop must not repeat it without refreshing the state behind “the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent” and checking for prior side effects.
Practical scenario
A support tool discovers zero remaining user resets and stops offering an automated region-change button that would only repeat the failure.
Difference from related HRESULTs
STG_E_CSS_REGION_MISMATCH reports incompatibility with the current setting; it says the setting cannot be changed through the normal user-reset path.
Developer and administrator guidance
Use authorized test media to cover fresh sessions, stale AGIDs, title changes, scrambled sectors, region mismatch, and exhausted reset counts.
Dashboards should keep it distinct and attach dimensions that can prove or disprove: the drive region cannot be changed because the user-reset count is exhausted or the setting is permanent.
