RAID Data Recovery

RAID Data Recovery by ECO Data Recovery is one of our specialties, and an area in which we consistently excel. Whether it be a RAID 0 with 1 or more failed drives, a RAID 1 with 1 failed drive, or a RAID 5 or RAID 10 with 2 failed drives, we have some of highest success ratios in the data recovery field.
Recovering data from a RAID server can be one of the most optimistic scenarios for data recovery, even when one hard drive has suffered from mechanical failure. If you do find yourself with a failed hard drive (or two) from a RAID 1  5 or 10 array, ECO Data Recovery can restore or recover your RAID, SAN, NAS, Snap Server. We have multiple, high capacity servers to tackle the larger RAID’S that arrive here for RAID data recovery.

RAID Data Recovery by ECO Data Recovery has been located in Palm Beach County for over 20 years. We moved from West Palm Beach in May of 2015 to a larger facility in Jupiter, Florida

NOTE:  Never Re-initialize your RAID array!

Utilizing custom software and hardware solutions for RAID Data Recovery, ECO Data Recovery is the ONLY choice for your vital data. Don’t be fooled by companies that offer on-site or worse, remote recovery options. Before any utilities are run against a RAID, all of the disks must be cloned sector by sector. (This is providing that all of the hard drives in the RAID array are in good working condition.) Anything less is possibly an irreparable accident waiting to happen. Just one foul up and ALL of your data can be lost. We have recovered RAID’s that have been at many of our competitors labs.

What is a RAID (Redundant Array of Independent Disks)

 RAID Data Recovery from a RAID 0:

All the disk devices are organized alternatively so that blocks are taken equally from all disks alternatively, in order to reach higher efficiency. Since the probability of finding a block of a file is identical for all disks, there are force to work simultaneously thus making the performance of the Meta disk almost 10 times that of a single disk.

Raid Data Recovery from a RAID 1:

In this mode, the goal is to reach the highest security of the data. Blocks of data are duplicated in all physical disks (each block of the virtual disk has a duplicate in each of the physical disks). This configuration provides 10 times the reading performance of a single device, but it degrades writing operations. Read operations can be organized to read 10 blocks simultaneously, one from each device at a time. Similarly when writing 1 block it has to be duplicated 10 times, one for each physical device. There is no advantage in this configuration regarding storage capacity.


RAID Data Recovery from a RAID 4:

In this mode the ultimate goal is to balance the advantages of the type RAID 0 and RAID 1. Data is organized mixing both methods. The physical 1 to N-1 are organized in striping mode (RAID 0) and the Nth stores the parity of the individual bits corresponding to blocks 1 to N-1. If any of the disks fails, it is possible to recover by using the parity information on the Nth hard disk. Efficiency during read operations is N-1 and during write operations is 1/2 (because writing a data block now involves writing also to the parity disk). In order to restore a broken hard disk, one only has to re-read the information and re-write it (it reads from the parity disk but it writes to the newly install hard disk).

RAID Data Recovery from a RAID 5:

This type is similar to RAID 4, except that now the information of the parity disk is spread over all the hard disks (no parity disk exists). It allows reducing the work load of the parity disk, that in RAID 4 it had to be accessed for every write operation (now the disk where parity information for a track is stored differs for every track)

RAID Data Recovery from a RAID 10 (0+1):

RAID 0+1: striped sets in a mirrored set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity. The key difference between a RAID 1 + 0, is that RAID 0 + 1 creates a second striped set to mirror a primary striped set. The array continues to operate with one or more drives failed in the same mirror set, but if drives fail on both sides of the mirror the data on the RAID system is lost.

IMPORTANT: If you hear any noises coming from a RAID hard drive, SHUT down your RAID ASAP!

RAID is NOT Data Backup!

A RAID system used as a main drive is not a replacement for backing up data. Data could become damaged or destroyed without harm to the drive(s) on which they are stored. For example, some of the data may be overwritten by a system malfunction; a file may be damaged or deleted by user error or malice and not noticed for days or weeks. RAID can also be overwhelmed by catastrophic failure that exceeds its recovery capacity and, of course, the entire array is at risk of physical damage by fire, natural disaster, or human forces. RAID is also vulnerable to controller failure since it is not always possible to migrate a RAID to a new controller without data loss.

RAID drives can make excellent backup drives, when employed as backup devices to main storage, and particularly when located offsite from the main systems. However, the use of RAID as the main storage solution cannot replace backups. This can lead to needing RAID Data Recovery.
