What You See:
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.
What It Looks Like:
- 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
What This Means:
This often points to metadata loss or array pointer corruption, not disk failure.
What’s likely happened:
- 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
What NOT to Do:
- 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.
Next Step:
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.
