Hi, here is what happened:
I installed and successfully run OMV on Raspberry pi 3, then connected 2 1TB disks:
WD Elements FAT32
Toshiba OSX journaled
Created a File System and could watch the disks, then unfortunately unplugged the two disk without unmount.
OMV3 got corrupted and I had to do a fresh installation.
The disks are no longer visible on OSX, Win, Linux nor OMV.
One seems completely dead although it spins and get very very hot
The second when connected to OSX gives me "USB Accessories Disabled Unplug the accessory too much power to re-enable USB devices",
on Raspberry pi "usb 1-1-port2: over-current change"
please help, all my data are in there!
