Troubleshooting Common Issues
1. No Drive Letter After Connection
Possible Causes:
- New PSSD not initialized or partitioned
- No drive letter assigned
- File system unrecognized by current system
- Defective USB data cable
- Poor USB‑port power supply or contact
- Compatibility issues caused by connection via hub, docking station or adapter
- PSSD hardware fault
Solutions:
- Switch to another computer USB port. For desktops, use rear‑panel motherboard USB ports preferentially.
- Replace with original or certified high‑speed data cable.
- Avoid testing through hubs, docking stations or extension cables.
- Open Windows Disk Management to check drive status.
- If capacity shows normally but no drive letter exists, manually assign a drive letter.
- For new drives with no critical data, initialize, partition and format the disk.
- If unrecognizable on multiple computers, contact after‑sales support for inspection.
2. Disk Management Shows “Unallocated”
Possible Causes:
- No partition created on new PSSD
- Partition deleted
- Corrupted partition table
- Lost original partition
Solutions:
- For new PSSD with no important data: create a new simple volume and format it.
- For PSSD containing existing data: do not directly create new partitions or format; evaluate data‑recovery options first.
3. Disk Management Shows RAW
- RAW means the system cannot identify the current file system.
Possible Causes:
- Corrupted file system
- No safe ejection before disconnection
- Abnormal power loss
- Transfer interruption
- File‑system incompatibility
- Storage‑media anomaly
Solutions:
- Do NOT click format if important data is stored.
- Stop writing new files immediately.
- Try reading the drive on the original host or another operating system.
- If data backup is unnecessary, re‑format and test.
- If RAW status recurs frequently, check PSSD health and contact after‑sales service.
4. Disk Management Shows “Not Initialized”
Possible Causes:
- Brand‑new PSSD
- Missing or damaged partition table
- USB communication error
- Faulty storage controller or flash‑memory medium
Solutions:
- For brand‑new empty drive: initialize as GPT or MBR as required.
- Do NOT initialize directly if the drive contains existing data.
- Test with different cables, USB ports and computers.
- If “Not Initialized” persists across multiple devices, send for further inspection.
5. Disk Management Shows “No Media” or 0 Bytes
Possible Causes:
- USB device detected but valid storage medium not recognized
- PSSD controller failure
- Flash‑memory hardware anomaly
- USB communication failure
- Faulty cable or USB port
Solutions:
- Replace the data cable.
- Change to another USB port.
- Test on a different computer.
- Avoid connecting via hubs or docking stations.
- If “No Media” / 0 ‑byte status appears on multiple PCs, contact after‑sales support.
6. System Prompts “The disk needs to be formatted”
Possible Causes:
- Corrupted file system
- No safe ejection
- Unexpected power loss
- Transfer interruption
- Target device does not support this file system
- Damaged partition table
Solutions:
- Do NOT perform formatting when important data exists.
- Try reading on an alternative computer or OS.
- If no critical data remains, format to a file system supported by your target device.
- After formatting, copy test files, safely eject, reconnect and verify normal operation.
7. Slow Transfer Speed
Possible Causes:
- Connected to USB 2.0 port
- Low‑speed cable or charge‑only cable
- Connected via hub, docking station or front‑panel USB port
- UASP disabled or device not running in high‑speed mode
- Transfer of numerous small‑size files
- Heavy background system workload
- Antivirus‑software scanning
- Very low remaining free space on PSSD
- Cache exhaustion caused by long‑duration writes
- Thermal throttling due to temperature rise
Solutions:
- Use USB 3.x or higher‑speed ports.
- Use original or certified high‑speed data cables.
- Desktop users prefer rear‑panel motherboard USB ports.
- Avoid hubs, docking stations and extension cables.
- Use single large files for speed testing.
- Close unnecessary background tasks and antivirus scans.
- Maintain adequate free storage space.
- Retest after the PSSD cools down.
8. Drive Drops or Disconnects During Operation
Possible Causes:
- Poor cable contact
- Loose USB port or unstable power supply
- Hub / docking‑station compatibility problem
- PSSD overheating
- USB disconnection triggered by system power‑management settings
- PSSD hardware failure
Solutions:
- Change the data cable.
- Switch to another computer USB port.
- Avoid hubs, docking stations and extension cables.
- Desktops should use rear‑panel motherboard USB ports.
- Retest after PSSD cools.
- Cross‑test on other computers.
- If frequent disconnections occur on multiple devices, apply for after‑sales inspection.
9. Cannot Read SMART Health Information
Possible Causes:
- Product does not expose SMART data externally
- USB‑bridge chip does not support SMART pass‑through
- Detection software is incompatible with this PSSD
- Insufficient system permissions
Solutions:
- Test with alternative diagnostic tools.
- Cross‑verify on Windows, macOS or Linux systems.
- Use manufacturer‑provided diagnostic software if available.
- Inability to read SMART does not always indicate fault if the PSSD can be recognized and read‑written normally.
- Further inspection is required if accompanied by drop‑offs, RAW status, format prompts, slow speeds or recognition failures.
10. TRIM Cannot Be Confirmed or Seems Inactive
Possible Causes:
- PSSD does not support TRIM / UNMAP
- USB‑bridge chip cannot pass‑through related commands
- System fails to identify it as a solid‑state drive
- Incompatible file‑system or partition status
- Inaccurate judgment from detection software
Solutions:
- Check product specifications for explicit TRIM support statement.
- Windows built‑in utilities can show TRIM status, but this alone cannot guarantee TRIM works for external PSSD.
- Confirm with professional TRIM‑aware diagnostic tools.
- If write performance degrades after long‑term usage: back‑up data, re‑format and reserve sufficient free space before retesting.
- If abnormal speed accompanies drop‑offs, error alerts or recognition loss: inspect cable, port, system and PSSD hardware.
(11. macOS NTFS read‑only)
Possible Causes:
- PSSD formatted as NTFS. macOS natively supports NTFS read‑only, without direct write permission.
Solutions:
- For cross‑platform Windows + macOS usage: back‑up data and format to exFAT.
- If NTFS must be retained: deploy third‑party NTFS write‑support software.
- Always confirm data backup before formatting.
12. Cannot Read on TV, Car‑Head‑Unit or Game Console
Possible Causes:
- Target device does not support current file system
- Target device does not support this drive capacity
- Target device does not support GPT partition table
- Insufficient USB power supply from host device
- Incompatible file format, codec, resolution or bitrate
- Overlong file path or file name
Solutions:
- Consult target‑device manual for supported capacity and file‑system limits.
- Format drive to FAT32, exFAT or NTFS following device requirements.
- Try MBR partition table for older devices.
- When video playback fails, verify video format, codec, resolution and bitrate.
- Validate first with small‑size files of common formats
