Your RAID controller shows all disks as online and healthy… but there’s no accessible volume. No drive letter, no mounted filesystem, and no way to access the data.

  • All drives marked “Online” in the controller BIOS
  • No volumes or LUNs appear in the OS
  • Storage Management tools show no usable space
  • The OS boots, but your RAID volume is simply… gone

This often points to metadata loss or array pointer corruption, not disk failure.

  • The RAID config (metadata) was overwritten, lost, or partially rebuilt incorrectly
  • The volume table or partition information is missing or mismatched
  • A rebuild was attempted earlier and rewrote the wrong stripe layout or mirror pair
  • BIOS/UEFI settings were reset and the RAID controller reinitialized without config import
  • Don’t try to reinitialize the array — that will overwrite what’s left.
  • Don’t create a new volume hoping it will match.
  • Don’t assume your drives are fine just because they show “OK.” Data layout can still be invalid.

Try viewing the current config using your controller’s BIOS or RAID manager tool — does it show the correct layout and previous volume? If not, stop immediately and get a forensic view.

🛠 Use JeannieLite to extract the true drive layout before anything gets overwritten. If you’ve already attempted a rebuild or config restore, this may still be recoverable — but don’t reboot again.
