envy 750-514 power supply failed. want to recover files on another computer. 160 GB ssd and 1 tb d

[von_b]

Using a SATA to USB converter. the 1 TB disk appears empty.  The 128 GB SSD had a bit locker password, which I had and entered/unlocked.  The resulting disk was not recognized and could not open.  The system the drives were connected to is a healthy Z8-G4 with current Win 10.

Windows 10 64 bit, not Win 8.  Sorry...

Hi @von_b, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like you're dealing with two different issues:

1TB Disk Appearing Empty

• If the 1TB drive is showing as empty, it could be due to:
  • Corruption in the file system
  • A missing partition table
  • Windows not recognizing the file system (e.g., if it was formatted in Linux or macOS)

Troubleshooting Steps:

• Open Disk Management (diskmgmt.msc) and check if the drive has a partition but no assigned letter. If so, assign a drive letter.
• If the partition shows as RAW, try running chkdsk /f X: (replace "X" with the drive letter).
• Use a tool like EaseUS Data Recovery or Recuva to check for recoverable data.
• If it's completely unallocated, try using TestDisk to recover the partition table.

128GB SSD BitLocker Issue

• Since you've entered the password but the drive is still not accessible, possible causes include:
  • Corrupt BitLocker metadata
  • Drive encryption issues preventing Windows from mounting it
  • The file system being unreadable even after unlocking

Troubleshooting Steps:

• Open Command Prompt as Administrator and run: manage-bde -status
  
  This will confirm if the drive is actually unlocked.
• If the drive is unlocked but inaccessible, try: repair-bde X: Y: -rp YOURRECOVERYKEY
  Replace X: with the SSD drive letter and Y: with a different drive to store the repaired data.
• Check if the drive appears in Disk Management. If it's RAW, you may need to recover data before reformatting.

I hope this helps. 

Take care and have a good day.
