RAID Data Recovery Services
We Can Help Recover Your Data!
Dataca has proven experience in recovering data from all types of high capacity and complex RAID arrays, NAS and SAN systems as well as Multi-disk server systems. We also understand the time sensitive nature of most RAID data losses and therefore offer emergency services standing by to offer you immediate and free phone assistance.
RAID is an acronym for Redundant Array of Inexpensive Disks. It is a method of connecting multiple hard drives together for better performance and/or redundancy if a single hard drive failed (availability). Server systems with Raid disk configurations are now commonly adopted by organizations to protect large volumes of mission critical data on file servers, web servers, database servers and other application servers. They are fault tolerant but not fault proof and as a result, usually leave customers with a false sense of security.
RAID arrays are very sophisticated and complex data storage devices, and as such they are often the most difficult to recover data from. RAID data recovery is a complex and specialized process as no two RAID systems are alike, and each RAID recovery presents its own intricacies and challenges. For this reason, RAID recovery should only ever be attempted by experienced recovery engineers. Dataca performs an initial sector by sector data cloning process prior to any data recovery attempt. We do not modify any of your hard drives at any time. Since a RAID configuration can consist of two or more drives and failures can occur in any one or more of these drives we require all the drives that make up the array.
Dataca supports and performs data recovery for all size, configuration, operating system or platforms of RAID array systems, SAN, NAS or other multi-disk server systems. We have the expertise to recover your data in a fast, secure and confidential manner so your business can be quickly operational again. Backed by our 'No Data, No Charge' service guarantee, Dataca provides you with the level of expertise, comfort and security you should demand in a data recovery firm. Our highly skilled engineers use state of the art recovery tools and proprietary techniques to successfully recover data from even the most badly damaged, corrupted and/or mechanically failed devices.
Common RAID Data Recovery Situations
We specialise in recovering data from RAID volumes with the following common problems:
- Corrupted RAID configuration
- RAID Controller failure
- Interrupted RAID rebuild
- Rebuild failure
- Damaged striping
- Multiple drive failure (or multiple drives go offline)
- Physically failed and faulty hard disk drive(s)
- RAID array or volumes that won't mount after a server crash
- Deleted or corrupted array configuration
- Deleted, overwritten or corrupted partitions
- Data corruption
- Changing a good disk instead of the bad disk
- Bad RAM or CPU
- Victim of power problems (surges, blackouts, brownouts)
- Bad sectors
- Unbootable system
- Multiple disk failure
- Chkdsk being run on one of the disks
- Computer virus/worm damage
- Human error
- Physical damage or mishandling
- Natural disasters.
- and all other RAID problems
RAID Data Configurations
We support a wide variety of RAID configurations. The most widely used include RAID 0, RAID 1 and RAID 5.
RAID 0 - Disk striping without parity
RAID 0 combines several large drives to create a single large volume. RAID-0 reads and writes faster than non-RAID configuration but doesn’t offer any data redundancy and requires a minimum of two hard drives to be totally restored as a requirement for completing a successful RAID recovery.
RAID 1 - Disk mirroring
RAID 1 simultaneously mirrors, or copies the content of one drive onto another drive. Performance is on par with a single drive plus it offers a level of redundancy from a single hard drive failing. However if one drive becomes corrupt then so does the duplicate drive.
RAID 5 - Independent Data disks with distributed parity blocks
RAID 5 is most commonly used configurations as it offers the best mix of redundancy, capacity and performance. RAID-5 stores parity information instead of redundant data. This parity information can be used to reconstruct the data. RAID-5 requires at least three and usually five disks for the array but can hold many more.
