This unit was on a Windows PC, plugged on a mac and formated to HFS+ (16Tb partition is visible when you put 5*3TB drive in the unit ... Strange)
Looked with winhex all the 16TB is full with 00
Checking the disque one by one :
Drive are not full of 00
Scanning the disk gives you some NTFS file structure, with jpeg that are off course corrupted
The information i found about drobo :http://arstechnica.com/business/2011/03 ... eview-1/1/
Entropy Analysis gives nothing, and parity tests too so...
I think customer with shelve it ...
