This is due to the destruction of physical sectors on the disks, which we cannot reverse. Sometimes, if a hard drive’s hard disk platters have become scratched or scored, a 100% complete disk image isn’t possible.

We make the necessary repairs in our Madison, Wisconsin-based data recovery lab, which features ISO 5 Class 100 cleanroom workstations and an ample library of replacement hard drive parts.Īfter repairing the drives, a data recovery specialist will make disk images of them as well as the healthy drives. But before we can do that, we must fix them first. We need to image the broken hard drives, too. The failed RAID 5 arrays we receive in our lab tend to have two or more failed hard drives. Step 2: Diagnose any broken drives, make the necessary repairs, and create as complete disk images of them as possible. However, if there is a second failed drive at the same time, the RAID array becomes inaccessible, resulting in data loss. Therefore, a RAID 5 array won’t crash, even if one of the independent disks fails. By using write-blocking tools, we ensure that we’ve created the most exact replica possible and can’t alter any of the data contained on the independent disks (on either the original drive or its clone).īecause RAID 5’s of data redundancy, it has single-drive fault tolerance in the event of drive failure. Our disk image is a 100% identical copy of the original drive, down to the last bit. Gillware’s first step in RAID 5 data recovery services is to take each of the all the disk drives in the failed array and create write-protected disk images of them. Step 1: Make write-protected (read-only) disk clones of each of the healthy drives in the array. Read on to learn what goes on in each step in further detail:
Extract all available data from the RAID 5 array.
If necessary, run a raw scan of the RAID 5 array to pick up any files which may have disappeared due to filesystem damage. Extract and test sample files to make sure the array has been correctly reassembled. Find the filesystem geometry within these logical units. Emulate the physical RAID 5 array and find the logical units on the array. Use the metadata on each of the disks to determine the RAID array’s geometry, drive order, parity, rotation, stripe size, and RAID algorithm. By analyzing the RAID metadata on each drive, determine which drive (if any) is stale and should be excluded. Diagnose any broken drives, make the necessary repairs, and create as complete disk images of them as possible. Make write-protected (read-only) disk clones of each of the healthy hard disks in the array. We have tested several “data recovery software” and chose ReclaiMe File Recovery because we found it the most comprehensible in the user interface and quite powerful in its function.How to Recover RAID 5 Data: Gillware’s 9 Step Method Gillware has a nine-step process to recover data from RAID 5 servers and NAS (network area storage devices): 1. Help to recover data in case of NAS failure.

Rather complicated device, there is special data recovery software which may The second drive also breaks down and the NAS stops working.Įven though unlike a regular hard drive, a NAS is a For example, one NAS drive breaks down, the array keeps working and theĪdministrator pays no attention to the situation. Like any device, NAS can get out of order and the data stored on it can becomeįactor. It means that one or even several drives (for example, To get a reliable file storage disk system one should choose NAS is designed to store information, the reliability of the RAID has an RAID0 and RAID1 layouts are used for such devices.ĭisk amount (3 or more) are typically combined into RAID 10, RAID 5 or RAID 6.
In its simplest configuration, a NAS consists of 1 or 2 hardĭrives and works the under Linux operating Usually, NAS devices have neither monitor nor keyboard. In short, NAS is a computer with drives and network controller. NAS (Network Attached Storage) devices are data storage devices that transfer the data via a network.
