Are you stuck with the factory-locked interface on your ? A new community patch has been released that removes the OEM skin and allows for:

The release represents a critical inflection point for devices relying on this controller. What began as a routine update to fix a power management bug evolved into a mandatory security and data-integrity patch. By understanding the vulnerabilities (command injection, DMA overflow) and the correct flashing procedure, you can protect your hardware from both malicious attacks and silent data corruption.

I recently acquired a batch of these "for parts" drives. One of them was spinning up but throwing an IDNG (Identification Error) in my terminal. The drive was alive, but it had amnesia. It couldn't read its own identity, let alone your data. The diagnosis? Corrupted firmware modules in the System Area (SA). lddh350aa75 firmware patched
