The Toshiba PX02SMU080 is an 800 GB SAS enterprise self-encrypting SSD, but “struggling” does not tell us whether the problem is detection, command access, security authorization, or a failing drive. Toshiba documents this model family as using the TCG Enterprise Security Sub-Class (SSC) and supporting Sanitize Instant Erase (SIE); that does not establish an Opal-based unlock procedure or prove that a particular drive can be reset without the required authorization. Start by identifying what the host can see and recording exact errors—especially if the data may need to be preserved.
What the Toshiba PX02SMU080 is
Toshiba’s 2015 manual identifies PX02SMU080 as an 800 GB formatted-capacity SED/SIE model with a SAS 3.0 interface rated up to 12.0 Gbit/s. Toshiba’s 2013 announcement lists it as an 800 GB, 7 mm-high model. These are product specifications, not measurements of a used drive’s present speed or health.

For the PX02SMQ/U security option, Toshiba specifies the TCG industry-standard Enterprise Security Sub-Class (SSC), access security, full-disk encryption, and SIE capability. Toshiba’s 2013 announcement describes AES 256-bit self-encryption and cryptographic erase for these enterprise SED models. Do not treat those facts as proof that this drive uses a TCG Opal workflow: the reviewed model documentation identifies Enterprise SSC, not an Opal unlock recipe.

Toshiba’s manual rates the drive at 10 DWPD, defining one full drive write per day as writing and rewriting the full capacity once each day for five years, the stated warranty period. That historical endurance specification does not establish the remaining life of any individual used drive. Toshiba PX02SM product manual

“Locked” is only one possible explanation
A drive that is absent, reports no capacity, returns read errors, appears locked, or rejects a management command can be failing at different layers. The observed symptom alone does not identify the cause. The host OS and kernel, controller or HBA model and firmware, drive state, command path, exact error output, and whether the data must be kept are all unknown until checked.
- Visibility or transport: the host or controller may not detect the target, or the connection may not support the needed SAS/SCSI command path.
- Ordinary SCSI access: the drive may be detected while inquiry, read-capacity, or other standard commands fail or are blocked.
- Security authorization: ordinary commands may work while protected access or a security-management request is rejected.
- Drive health: read errors or other faults may point to a failing device, but a generic tool error or a 0 MB/s display alone does not establish that diagnosis.
These are distinct questions: whether the host can communicate with the target is not the same as whether it can authenticate to the drive’s security features.
Collect evidence before changing drive state
- Verify the label. Record the complete model number for each drive and note the host, operating system and kernel, controller or HBA model, and controller firmware.
- Check detection at both layers. Record whether each drive appears in the controller’s inventory and the operating system’s device list. Note any differences between them.
- Test ordinary SCSI access. Where the system supports it, record the SCSI inquiry and read-capacity results through the current connection. The sg3_utils documentation explains that its tools send SCSI commands over SAS and other SCSI-command transports, and require a device node that supports SG_IO. This can help establish whether ordinary commands reach the target; it does not prove that a security command is supported, passed through, or authorized. sg3_utils documentation
- Save exact errors. Capture the command used, the complete response or sense data, and relevant controller and OS logs. Distinguish a transport or visibility failure from an explicit security-status response rather than inferring “locked” from a capacity display or generic error.
- Decide whether the data matters. If you need to preserve existing data, do not attempt sanitize, revert, reset, or formatting operations.
- Check an exact-model procedure before any security action. Use a procedure documented for this TCG Enterprise SSC drive and controller, with the required authorization. Toshiba’s description of SIE is not an unlock or recovery procedure.
Do not post passwords, keys, or PSID-like secrets when asking for help. Share the non-secret model, controller and firmware details, command output, and the goal—data recovery or reuse—instead.

How to choose the next step
| Goal or finding | What it establishes | Safer next move |
|---|---|---|
| Preserve existing data | Erase or reset operations could destroy the data; the symptoms do not establish recoverability. | Do not sanitize, revert, format, or reset. Gather read-only identification and error details, then seek a recovery path appropriate to the drive’s documented security model. |
| Drive is absent from the OS or controller | The command path or physical detection is not established, so security status cannot yet be inferred. | Check connections, controller inventory, and logs; determine whether the current controller exposes the target before investigating drive security. |
| Drive is detected and ordinary SCSI commands work | The host can communicate with the target for those commands, but this does not prove security-management pass-through or authorization. | Record exact security-command responses and consult an exact-model, controller-appropriate procedure before changing state. |
| Current controller blocks ordinary SCSI commands | The existing path may be limiting diagnosis; no specific adapter compatibility is established for these drives. | Consider a SAS HBA or controller that supports the required SCSI pass-through only after confirming compatibility with the system and intended commands. |
| Goal is erasure and reuse | SIE is a sanitize/cryptographic erase capability, not evidence that an unknown drive can be unlocked without credentials. | Proceed only with a documented procedure for the exact security model and the necessary authorization, accepting that erasure destroys access to existing data. |
What cannot be concluded yet
Without the host and controller details, exact command and error output, drive visibility, and whether the data must be preserved, it is not possible to identify why these particular drives are “struggling” or promise that they can be unlocked or reused. Toshiba documents security and SIE capabilities for the model family, but the documentation cited here does not provide an owner-specific recovery procedure or show that these individual drives can be reset without authorization.
