RAID0 Recovery - YouTube

Hi! Welcome to the ReclaiMe channel where we discuss different aspects of data recovery.

Now I would like to show you how to recover the data from RAID 0 array.

RAID 0 is one of the simplest RAID levels.

It is needed at least two disks to create it.

You can create RAID 0 using a hardware controller

or a special software or a NAS device.

For example, 2-bay Buffalo NASes used RAID 0 level by default in their early devices

I hope, that they changed this setting in the latest devices.

RAID 0 level isn't so popular among users

because it doesn't provide any redundancy.

And if one of the array member disks fails, all the data is lost.

So, now let's see how the data is written to the RAID disks.

Disk 1 and disk 2

Data blocks are placed in such a way.

In RAID0 block size is usually well under 1 MB

which means that any file is evenly spread all over the member disks.

Therefore, if you lose one disk

data recovery for all practical purposes can be considered impossible

because all you get are files no larger than the block size.

Thus, if you need to recover the data in case of a disk failure,

don't waste your time and turn off this video because you won't succeed.

But if you deal with a failure not associated with array member disks,

for example a hardware controller failure,

a controlling software failure or accidentally deleting the file

I will show you what to do

Firstly, we need to recover the RAID configuration, which includes

number of disks, disk order,

what the disk was the first

start offset and block size.

For this purpose, we will use a free tool - ReclaiMe Free RAID Recovery software.

So, my RAID0 includes 2 disks

and was created with this hardware controller

Firstly, we need to remove the disk from a controller

and connect them to the PC.

It's better to connect the drives directly to the PC motherboard

However, if this is impossible

you can buy a special USB to SATA adapter

But take into account the fact

that with these adapters disks are often not detected

or software freezes or disks drop offline

So, now connect our drives to the PC

So, remove the front panel using screwdriver

I have only one free SATA port

so, I connect one drive directly

and another drive using USB to SATA adapter.

Connect SATA

and power

And connect adapter

Go to www.FreeRAIDRecovery.com site

and click Download

Select all RAID0 disks

and click Start RAID0 button

Wait until software analyses data on drives

The RAID 0 recovery finishes

when either Scan or Confidence progress is completely filled.

The Raid recovery is done,

the software recovered the configuration.

Then, to restore the data,

you should click «Run ReclaiMe to recover data.»

Choose our RAID volume

and click Start.

Folder tree appears

and then you can check the quality of recovered files.

If the files are displayed correctly in the preview,

so they will open correctly after saving.

Some type of files like exe,

are displayed in hexadecimal representation.

Don't worry

They also will open correctly after saving

You do not have to wait until the scan is completed.

If you see that the expected amount of data has been recovered

and the indicator of number of recovered files has stopped growing

you can start to save the recovered data.
