MediaSonic external drive now empty
Posted on 2014-04-09
Working with a MediaSonic 4Bay USB device configured as RAID 5 with (4) 2TB drives.
User has stored a lot of data on it over the last several months.
It shows up on the system as the w: drive.
Yesterday, he went to access it, and all it would display is a folder labeled "System Volume Information."
There are no red lights on the fornt panel. User reports one orange light... but I have to wait for them to return to their office to confirm which one it is.
We have tried restarting the unit.
We have tried restarting the PC
We have powered the unit down. unplugged it from the PC, then powered the unit on... then plugged in the USB cable.
None of the above had changed anything.
In windows explorer, if I right click on W: and select properties, it shows a total of 8T unused... and only 315 MB used (the size of the System Properties folder.
If I go to disk management it shows as as
New Volume (w:)
8383.28 GB NTFS
Healthy (Primary Partition)
NOTE 1: This unit has a button on the front top right panel that you can hold down for three seconds and change the RAID mode. NOTE: holding a button down is not an uncommon means of shutting a piece of hardware off.
I suspect user tried to power off the unit by pressing this button.
Any other explanations or recovery ideas anyone can suggest?
