When to Use Stellar Data Recovery Technician?

Accidentally deleted or lost RAID data

The advanced Stellar Data Recovery Technician performs RAID recovery from logically corrupt, inaccessible, crashed, or failed RAID arrays. Use the software for seamless recovery of data lost from RAID volumes or disks due to accidental deletion, file system corruption, malware, logical errors, software glitches, or power outage.

Incorrect rebuild of RAID array

Sometimes, a RAID rebuild fails due to wrong configuration, logical corruption, incorrect stripe size, missing disk, or wrong disks order in RAID array, which erases data on the disks. Leverage the capabilities of Stellar Data Recovery Technician to retrieve data lost due to incorrect rebuild of RAID server.

RAID error messages

Read/write errors while accessing data, such as ‘Can’t read data from RAID disk’ or ‘Unrecoverable Read Error’ result in data loss. RAID errors make volumes unreadable making its data inaccessible. Get Stellar Data Recovery Technician software to restore data from inaccessible volumes and disks that throw RAID errors.


Software Important Capabilities

Recover Data from an Inaccessible RAID Volume

Recover Data from an Inaccessible RAID Volume

Stellar Data Recovery Technician recovers data from logically corrupt and inaccessible RAID 0, RAID 5, and RAID 6 volume and partitions. The RAID data recovery software for Windows works without the RAID controller card. It scans for the deleted/lost RAID volumes, and recovers data from RAW and missing RAID volumes.

Recovers Data from SSD RAID array

Recovers Data from SSD RAID array

RAID using solid-state drives (SSD) sometimes fail due to RAID controller failure, software glitch, sudden power outage, RAID errors, worn out SSD connectors, overheat, and other reasons. Stellar Data Recovery Technician recovers data from SSDs using RAID 0, RAID 5, or RAID 6 array. It supports recovery from formatted, deleted, or logically corrupted SSD RAID drives.

Formatted RAID array recovery

Formatted RAID array recovery

The reliable Stellar Data Recovery Technician recovers data from formatted RAID 0, RAID 5, and RAID 6 logical volume and partition. It automatically rebuilds a virtual RAID array and lets you save the recovered data to an internal/ external disk, even when you don’t know the RAID parameters for reconstruction.

Deleted RAID partition recovery

Deleted RAID partition recovery

Recovers your critical data from a deleted, lost, undetected, failed, or corrupt RAID partition. The powerful Stellar Data Recovery Technician scans and retrieves data on RAID partition lost due to accidental deletion, failed RAID stripping, sudden power failure/ system shutdown, malware/ virus intrusion, bad sectors, software related errors, and other.

Recovers from RAID configured NAS

Recovers from RAID configured NAS

The efficient Stellar Data Recovery Technician recovers lost data from NAS devices configured to RAID 0, 5, or 6. It recovers data from corrupted and inaccessible RAID-based NAS servers of Iomega StorCenter, Buffalo Terrastation, LinkStation, Synology, LaCie, QNAP and other Linux-based NAS devices. 

Supports Recovery with Virtual RAID Construction

Supports Recovery with Virtual RAID Construction

Stellar Data Recovery rebuilds probable RAID if its parameters such as number of disks, file system, block size, parity order and other details are not known. The software automatically matches patterns and identifies the RAID parameters as you select the 'Don't know' checkbox and specify the possible values for Strip Size, Parity Order, Parity Delay, and other.

Recovers Hardware and Software RAID

Recovers Hardware and Software RAID

Stellar Data Recovery software recovers data from hardware and software-based RAID 0, RAID 5, and RAID 6 arrays. The tool supports data recovery from hardware-based RAID servers without a controller cards or additional hardware and software requirements.

Recovery from Non-Booting Windows System

Recovery from Non-Booting Windows System

Stellar Data Recovery Technician software restores RAID data even when your Windows system fails to boot. The advanced RAID recovery tool creates a bootable USB media that you can use to boot the Windows system, following which initiate RAID data recovery.

Yes, it is necessary to reconstruct the RAID. Stellar RAID Data Recovery software verifies the consistency of data in the reconstructed RAID drives. Only after rebuilding the RAID, you will get probable RAID constructions, on which you can perform various data recovery operations to recover your data.

It is suggested to enter the RAID parameters, if you exactly remember them. Wrong information can mislead the software and lessens the data recovery chances. However, if you don't at all remember the RAID parameters, the software provides option to mention 'Don't Know' in the field given and choose all possible options for the corresponding parameter. In such a case, this RAID hard drive recovery software searches for all specified parameter options and create the probable RAID constructions.

Yes, you can easily recover all your deleted or formatted data from the RAID drives. Once you rebuild the RAID, you can select and scan the drives or the virtual RAID drive. Once the scan gets completed, select the files you want to recover from the scanned list. Then select 'Recover', choose the destination and click 'Start Saving'.

Yes, the software is able to recover data from such a condition. There are many situations, when two or more RAID drives get logically corrupt and the normal rebuild operation fails. Stellar Data Recovery Technician software is especially designed for such instances of severe RAID array corruption and efficiently recovers all your data from the troubled drives.

No, there is no need to have the RAID controller card while recovering data from the troubled RAID Drives using RAID recovery software by Stellar.

If the software fails to create probable RAID construction, the software shows another option – 'Create Virtual Drive'. You can still perform this virtual RAID drive, perform raw recovery, and search for the lost volumes in it.

Yes, in order to perform RAID Recovery, the software requires all your member RAID drives. You also need to specify proper sequencing of these drives for successful recovery.

Yes, most of the times, the data is recoverable after re-formatting the RAID 5 volume, depending upon the way that how you’ll re-format the drive. Using Windows, if we do a re-formatting of a volume, then, it will create what exactly appear to a ‘clean’ new volume; but, the original data will still appear on the disk in the ‘Free and Available’ space. However, a low-level format, which has been performed by the RAID controller utility will completely ‘Wipe’ overwrite every single block on a drive. A low-level format is slower than high – level format.

If you have deleted a partition then you can easily recover it using the ‘Can’t Find Drive’ feature of the RAID drive recovery software.

Yes, if the NAS is based on RAID 0,5 or 6 then this software can recover your data, you just need to specify the parameters and if you don’t know them then you can use the ‘Don’t Know start sector of drives ’ feature.

A RAID system can fail and data becomes inaccessible due to:

  • RAID Controller Failure
  • Multiple RAID Hard disk Failure
  • Intermittent drive failure resulting in RAID degradation
  • Accidental reformatting of drives or whole RAID array
  • Failed Rebuild or Lost RAID Array configuration etc.
  • Immediate RAID Server Crash due to Power issues
  • Application/software corruption etc.

Stellar Data Recovery Technician supports 300+ file types and allows you to add additional file types apart from those already mentioned in File Lists. Using Add Header option, user can add a new file type or edit an existing file type to facilitate the RAID data recovery process.

The importance of using Drive Monitor is that you can use it to prevent drive failure or corruption of your drive by regularly checking the health, performance and current temperature. If you notice that the health and performance of drives are low, clone your hard drive to remove bad sectors. The reason being, bad sectors in hard drives are a leading cause of poor health and performance.

Yes, you can recover the data lost from 4K hard drives using Stellar data recovery software. The tool works with all leading make and models of 4K drives/

Yes, the software fully supports dual-screen setups and enables a native data recovery experience.
