Disk formatting is basically the preparation of a data storage device such as a hard disk drive, SSD, floppy disk or USB flash drive for use. It adds a file system to the device, in some cases multiple. This is usually done after partitioning the device if it was completely blank/wiped prior to use. For example, the user could format a USB stick with the exFAT file system. This particular file system can be recognised by both Windows and MAC operating systems.

In the case of some operating systems, these procedures can be repeated at any time or even combined on certain devices. Generally this is so the new device can be recognised on multiple machines (iMac or PC) however reformatting a drive does have the major pitfall to a user in the context of wiping the data present on that particular at that current time, so it is best to be completely aware of this before attempting to format a device.

One of the most common recoveries we perform here at R3 Data Recovery Ltd when it comes to SD cards especially is accidental formatting.

DROBO storages systems are very powerful and scalable, but recovery from these units is usually very complex.

DROBO is a series of multi-disk devices, which can be either DAS or NAS. Typically, a DROBO has 5 or 8 drive bays, accepts disks in any combination of capacities and produces maximum size single storage out of them, given the desired fault tolerance. This storage is, in turn, either divided into LUNs (virtual physical drives) and presented to the OS as single USB or virtual physical drive.

To combine several physical disks into a single storage, DROBO uses its own technology called BeyondRAID, which is not like any standard RAID level. The BeyondRAID technology uses a combination of RAID1 and RAID5 for single redundancy and 3-way mirror along with RAID6 for double redundancy. DROBO uses different RAID levels for metadata and user data. More than that, even different block sizes can be used on the same DROBO disk pack and LUN. The possibility to recover DROBO data directly depends on whether you have the map of where all the blocks are written or not.

In this case, the customer has plugged all drives from his broken DROBO to a new one but from a different family.

The result was that the disk set was reinitialized and a different map was overwritten. Luckily the new map was (or maps because actually there is more than a copy) written to different locations so the original ones were preserved.

Logical analysis, anyway, could not find any file or structure: the software had detected the new DROBO file system and was trying to reconstruct it. Why look for a different set of data if I have found a good signature of it?
