What is RAID?
RAID is a disk group with huge capacity.
It usually consists of several cheap disks, RAID is an acronym for Redundant
Array of Independent Disks.. A individual disk in this disk group provide data
and produce addictive effect so that to improve the system effectiveness of the
entire disk. RAID can be divided into different types.
Causes for people
to use RAID
1. RAID has a high transmission speed
2. It provide fault tolerance function
through data parity
Why RAID fails?
1. Hardware failure:Like RAID corruption,
controller failure, array failed.
2. Software failure: partition lost,
backup failure, corrupted files
3. Human factors: data overwritten,
partition format, sudden power shortage and other improper operations.
How to recover
data from RAID?
Once there are failures detected on RAID
disk array, please save your files and shut down your computer properly. DO not
attempt to perform some recovery operations. You should ask data recovery
experts to help you recover your data, or use the data recovery software to
retrieve them.
Hdata recovery software can
help you to recover data from RAID.
First, download and run Hdata recovery
software on your computer
Second, Choose the recovery mode on the
interface of software. If you lost your partition, then you should choose “Hard
drive partition lost or crash”. Click Next.
Third, choose the partition you lost
files, click Next to search for files.
Fourth, after scanning, preview the
results, restore all of them or choose customized files to recover.
Fifth, choose a recovery path to store
data. Keep in mind do not save to the partition you lost files, or the
recovered data will overwritten your deleted data.
If the file recovery software can not help
you to get your data back, you have to ask the data recovery experts to help
you though RAID data recovery is expensive. Do not try any other operations on
the failed drive.
