Remote SSH Shutdown bricked my PR4100
If a remote SSH shutdown bricked your WD My Cloud PR4100, don’t panic — in many cases it’s recoverable. The WD My Cloud PR4100 can appear “dead” after an improper shutdown, firmware issue, or corrupted OS partition.
🔍 1. Check the Basics First
✅ Power Check
Unplug the power adapter for 5–10 minutes
Plug it directly into a wall outlet (no surge protector)
Try powering on again
✅ LED Behavior
Note what the front LED does:
Solid Blue → System OK
Flashing Blue → Booting
Solid Red → System error
No Light → Possible power board issue
LED status helps determine if it's firmware or hardware.
🔄 2. Try a 4-Second Reset (Safe Reset)
This does NOT erase data.
Power on device
Press and hold reset button (rear) for 4 seconds
Release when LED blinks
Wait 5–10 minutes for reboot.
🔁 3. Try a 40-Second Reset (System Only Reset)
If 4-sec reset fails:
Power on device
Hold reset button for 40 seconds
Device should reboot and restore OS configuration
⚠ This resets settings but keeps data intact.
💻 4. Check If It’s Still on the Network
From your PC:
Open router admin page
Look for PR4100 in DHCP client list
Or use WD Discovery tool
If it gets an IP address, try accessing:
If accessible → firmware likely corrupted but recoverable.
🛠 5. Firmware Recovery (Advanced)
If SSH shutdown interrupted system services, the OS partition may be corrupted.
Options:
Option A: USB Firmware Recovery
Download correct firmware from Western Digital support
Use USB recovery procedure (requires specific firmware version)
Option B: Drive Rebuild (Last Resort)
The PR4100 stores the OS on each drive.
Power off device
Remove all drives
Label drives in order
Insert ONE blank drive
Power on
If it boots → original OS partition corrupted.
⚠ Never initialize original drives unless you have backups.
🚨 6. If Completely Dead (No LED, No Fan)
Possible causes:
Power adapter failure
Internal PSU issue
Motherboard fault
Try a known-good compatible adapter before assuming board failure.
❓ Important Question
When you ran SSH shutdown:
Did you use shutdown -h now?
Or poweroff?
Or did the device lose power immediately after?
That detail helps narrow it down.
If you tell me:
LED status
Does fan spin?
Does it get an IP?
RAID type you were using?
I can guide you step-by-step for your exact situation.
