Hello everybody!
Watch this video to find out how to recover data from a damaged RAID 5 array on Intel
Entry Storage System SS4000-E NAS.
We will explore aspects of its initial configuration, learn how to create a RAID array, set up network
access and add a shared folder.
These days, the issue of reliable file storage becomes particularly urgent.
Over time, almost every PC user - even if that’s a proverbial ordinary home user without
regular access to local or global networks - comes to accumulate gigabytes of information
- photos, videos, documents and other stuff.
The risk of losing everything in one second and forever only because your hard disk breaks
down is quite high.
Yes, modern motherboards let users create fault-tolerant software RAIDs,
but there are also considerable reasons to choose a specialized solution in the form
of a NAS device, as disk arrays in such devices are built on a hardware level.
Also, increasing the number and volume of hard disks in an individual computer can hardly
be seen as a good solution, as it pushes up the noise level and requires better power
supply and cooling options.
A dedicated NAS storage will ensure the safety of your data and access to it over the network.
The RAID technology is quite a reliable way to store important information, but there
are certain factors which cannot be ignored with any kind of technology available these
days.
Just like any other device, NAS is not perfect and may break down after many years in service.
As a result, you will lose access to your files stored there.
In today’s video, I’ll show you how to organize storing your data on Intel Entry
Storage System NAS, model SS4000-E, and how to bring its data back if your NAS breaks
down, if a hard disk fails, or if you remove a file by mistake.
How to configure your storage For starters, let’s explore initial configuration
of a network-attached storage system.
Open a browser and type the server’s IP address.
Give the default login - admin - and password - storage.
After sign-in, you’ll see the system initialization screen.
If you don’t see the connected disks on this list, slick Scan, and then Start to begin
the configuration process.
Certain information will be written, and the disks will be partitioned; after that, the
NAS will reboot, so let’s wait until it is ready for work again.
Soon you will see the welcome screen.
Click Next to continue with the configuration.
Accept the license agreement - Next.
At the first stage, you need to give a name to your storage system, and set up date and
time, choose network settings, and the disk array type.
This device lets you create one of the three RAID types - 5, 0 or 1.
What we need is RAID 5.
In the disk space settings, give the disk size and click Finish, then OK to confirm
your choice.
You can only change these disk configuration settings at the cost of data loss.
Also, you will lose common folder, user and group properties.
In theory, the last option of disk configuration lets you add more disks later without losing
data, but it doesn’t offer you any reliability.
Wait until the system is configured, and when it happens, the device will reboot automatically.
Give the default login - admin - and password - storage.
It will open the storage management page; this is where you can create a new user or
a group, shared folders, and also access administration features.
How to configure access by FTP For starters, let’s configure network access
to the storage via the FTP protocol.
To do it, open the menu tab Advanced and browse to Network.
At the bottom of the screen, enable FTP server and click Apply to save the settings.
How to create a new user Now let’s create a user that will have access
to a shared folder by FTP.
Open the tab Users and click Add to create a new one.
Specify the connection type, the login and the password.
How to create a shared folder Now let’s create a new shared folder.
Open the tab Shared Folders.
Click Add, give a name, select a user that will be provided network access, set read
/ write permissions, and click Apply to save the changes - and finally, click OK.
Later, you’ll be able to connect to your NAS by FTP and upload your files.
The configuration and current state of the disk system are displayed if you navigate
to the tab Advanced - and click on Disks.
At the moment, resynchronization process is underway - the disk space is being created.
By pressing this button, you can edit the configuration by changing the RAID type and
volume size.
But as I said before, you can’t possibly make any changes to the RAID type without
losing data.
How to recover data from a non-working Intel Entry Storage System SS4000-E NAS.
If your NAS is down, or one or several disks in the array are no longer functional, and
as a result of that you have lost access to some data which still remains on its disks
- a specialized data recovery tool - Hetman RAID Recovery - will help you bring your files
back.
This program supports all popular RAID types and most file systems.
It can also help you rebuild a damaged RAID, even if one or several disks within the array
are out of order.
You’ll be able to restore critical information, which is still on the disks, and do it without
actually using the NAS.
Take the disks out of the network storage and connect them to the motherboard of a Windows
computer.
If your motherboard lacks SATA ports to connect all the disks, or you have a similar problem
involving power connectors, you can solve the problem by using special expansion cards
and adapters - which are now displayed on the screen.
With this type of device, RAID arrays are based on IPStorPartition technology, and many
recovery tools don’t support it.
Meanwhile, Hetman RAID Recovery can properly handle arrays with this technology.
As you can see, the program has built the RAID system automatically and now displays
all the information about the array.
To search for files, right-click on the disk and select Open.
Choose the search type, Fast scan or Full analysis.
For starters, we recommend a fast scan - the utility will promptly analyze the disk and
display all the detected files.
If the “Fast scan” can’t find the required files, then go for “Full analysis,” select
the file system and click Next.
In most complicated cases, we recommend searching files by their signatures, by checking the
box next to Content-Aware analysis.
The program has found all the files stored on this array.
For your convenience, there is an option to search for files by their names.
Also, you can check file contents with the preview option.
Removed files are marked with a red cross.
Look for the ones you need to restore, select them and click Recovery.
Choose the folder where you’d like to save the files and click Recovery again.
When the entire process is over, you will find the recovered files in the folder you
have chosen.
How to rebuild a damaged RAID manually In very complicated cases, when critical service
data was erased from the disks, the program may fail to rebuild the RAID automatically.
Luckily, for such cases this program features a manual way for rebuilding the RAID in a
special constructor mode.
To use this mode, you need to know all the information about the damaged array.
Open RAID Constructor, select Manual mode, click Next and fill in the array data.
RAID type, block order, block size, add the disks included into the array and specify
their order.
As a result, it should appear in this window; if you got all the properties right, you will
see the directory tree If you see none, it means the properties are incorrect, or this
information is insufficient to identify the RAID.
You may have to specify the offset which tells you where the beginning of the disk is located.
You can find this information with the help of HEX Editor.
When all the properties are ready, click “Add.”
After that, the array will appear in the Drive Manager.
Now the last step is to scan it using Fast scan or Full analysis, and recover the
files you need to restore.
That is all for now!
