After I have lost 1.5 TB of personal data and having a terrible time getting a hardware replacement, I did my own investigations on the Droboshare issues.
This is my result and I would like someone from Data Robotics to comment on this.
Droboshare is based on a free embedded Linux system.
It is known for quite some time that Linux systems do not have a reliable HFS+ support (which is the standard file system for OS X and thus also for Drobo’s used with a Mac) . Actually, people who know a lot about these technical details even told me that the HFS+ support is a lot of crap.
One of the „not so obvious“, but most dangerous operations you can do with a Drobo (HFS+) & Droboshare is simply to delete files. Under certain circumstances (and I tested this personally!!) it will destroy directory information (so, e.g. files or folders simply disappear) or (as in my case) the whole disk structure gets corrupted and you loose your data.
Technically, when deleting a file Drobo & Droboshare may not recover the new available space and, in the worst case, can leak free blocks somewhere on the directory structure.
This is obviously the reason why all the time the recommendation is „connect it directly with your computer and run disk repair“ because then Apple’s own correct HFS+ implementation will perhaps repair the damage Droboshare caused to the file system. Or not, like in my case.
==>Can anyone from Drobo please comment when this is going to be fixed?
I am not going to accept that Drobo is selling this device and claims that it works perfectly with OS X and HFS+.
