Mybook II: /usr/sbin/parted: write error: Broken pipe

My NAS went into degraded mode recently.  I followed instructions on another thread to enter Advanced Mode - Storage-Disk Manager to diagnose a faulty disk. But when I tried to enter the Disk Manager, I get this error

/usr/sbin/parted: write error: Broken pipe

PS - the whole device is now running like a dog.  With broken legs.  And a concrete overcoat.  

Any advice / support welcomed.  


I thank you

Just spotted a firmware upgrade.  Clutching at straws…

no, the firmware update process seems to timeout… :o(
