Storage systems

NAS, SAN OR DAS systems

NAS, SAN or DAS systems allow you to store information remotely and meet connectivity or data storage needs in a secure manner and thus avoid the loss of information so do not resort to data recovery services.
If we are talking about a private use / small company, a NAS or DAS are storage systems that allow a balance between price, capacity and security both in data protection and in data recovery after a failure of some disk drive.


DAS system

A DAS (Direct Attached Storage) system although it could be considered a hard drive for this purpose, in recent years devices made up of more than two hard drives that are connected by USB> have appeared or Thunderbold cable to be able to operate with them without any other connectivity. With various capacities, they can operate in various formats such as RAID 0, RAID 1
or RAID 5


NAS system

A NAS (Network Attached Storage) system is a device that allows remote connection via a Wi-Fi or RJ45 system, expanding the possibility of storing data remotely. The vast majority work in RAID 0, RAID 1 or RAID 5 format, although there are also units with only a mechanical hard drive.


DAS vs. NAS system

DAS (Direct Attached Storage) systems are more focused on the home user, since they do not usually need the remote connectivity offered by a NAS. Likewise, the price of DAS is usually much cheaper than its equivalent in NAS. You have to understand that the NAS has an operating system (mostly Linux) configured to have remote connections and many other applications focused mostly on semi-professional use.


Operating systems

The internal operating systems of the DAS and NAS, as we have mentioned, are usually Linux and their partitions are generally EXT 4 or XFS. They are safe and robust operating systems, but complex when it comes to being able to recover the information when one of the hard drives is damaged. Even data erasure can be complex due to the specific design of these operating systems. They have been designed so that deleted information cannot be easily recovered.


SAN system

The SAN (Storage Area Network) systems are intended for the professional field. The main difference is the use of connection cabling (fiber optics), the connection protocol iSCSI and the hardware architecture that surrounds all hard drives. They are usually multi-disk arrays, capable of running simultaneous virtual machines. Recovery of SAN devices mostly with multiple LUNs and virtual machines is usually very complex due to the use of VMWARE systems and virtualized environments.

Trust Laby, we can recover the information from your NAS drive.

Whether it is a NAS, SYNOLOGY, WESTERN DIGITAL MYCLOUD, WESTERN DIGITAL DUO, QNAP, BUFALO, VMWARE system or systems with iSCSI protocols, we can help you.

Recover data from NAS, SAN or DAS


NAS, SAN or DAS devices can fail for multiple reasons.
The failure of a hard drive can make the NAS, SAM or DAS inaccessible. Although they are configured in the vast majority of cases with RAID 5 type redundant systems, other configurations can cause the system to hang.

Other times, an internal operating system failure or a problem with surface degradation on one or more of the drives can cause data loss on a NAS, SAN or DAS device.

Sometimes, the system can hang, allow partial access to data or simply show the list of files but not allow access to it.

Deleting information from a NAS, SAN or DAS device and proceeding with its recovery is complex due to the file system used.

In order to determine the failure and scope of the failure, it is necessary to review the physical drives that are in failure for repair and imaging, determine the file system and its structure and attempt data access. All these processes are complex since there are many possible combinations both in parameters and in the logical format of the units (LUNs).


A NAS, SAN or DAS device is a compact box consisting of several hard disks that are connected via a network cable to the system, hence the common name network hard disk.

If you have problems with the NAS, SAN or DAS system, it does not work or you cannot access the data, our recommendation is to disconnect it and contact a specialized data recovery service.

If you tamper with the broken device or try to recover the data with a program without success, you could complicate and make the process of recovering the information stored on the NAS, SAN or DAS more costly. Even to the point of making it unrecoverable.

To avoid further damage to the device:

Turn off the device as soon as possible. It will prevent further damage that may condition the recovery process.

Do not tamper with the device. Forcing screws, or opening it in an uncontrolled, dust-free environment can adversely affect the chances of recovery. Remember that the inner parts are very sensitive and delicate.

The use of recovery software in physical cases may permanently damage the device. Avoid using it in such cases.

Contact a data recovery laboratory. These are the professionals who have the tools and adequate training to be able to evaluate and carry out the data extraction and recovery processes.

Un día mi disco duro de 5TB dejó de funcionar y hacía un ruido extraño; pensaba que sería un daño menor y lo llevé a un informático que después de 3 semanas intentando recuperar los datos me dijo que los archivos salían corruptos. Un segundo informático lo intentó con un software y tampoco pudo. Decidí recurrir a un laboratorio, pero en mi ciudad no hay ninguno, así que una mañana llamé a Laby, me explicaron amablemente los pasos y en unas dos horas pasaron a recoger el disco duro en mi domicilio para llevarlo a Barcelona. Pudieron recuperar casi todo y aunque 800€ es un precio elevado tenía la opción de aceptar o no ese presupuesto; en mi caso acepté porque le doy mucho valor a esos archivos. Quedé muy contenta con el trato, la buena comunicación y la profesionalidad. ¡Muchas gracias!

Muy amables y profesionales. Recuperaron practicamente todos los datos de un disco duro externo que llevaba estropeado desde hace unos años.




The price to recover data from hard drives on NAS, SAN or DAS devices will always depend on the damage suffered by the drives, together with the hours of work and technical equipment required to carry out the recovery processes.

In any case, a prior diagnosis is necessary to detect the type of failure or combination of various failures. Below we detail the most common breakdowns and the reference prices:

From €250 / + vat

For logic or board faults:

  • Access problems to damaged partitions, bad sectors or surface degradation / Electronic boards burned / damaged by short circuit, wrong voltages or burned components.
From €350 / + vat

For Firmware faults:

  • SW internal disk corrupted. Damaged modules.
From €450 / + vat

For engine breakdowns:

  • Over temperature or motor unit failure.
From €450 / + vat

For head failures:

  • Surface degradation or reader unit failure.

If it is a set of disks

From €450 / + vat

For logic or electronic board faults:

From €890 / + vat

For head failures:

Determining the price of data recovery from a NAS, SAN or DAS device is extremely complex. It is necessary to know first of all if the failure is physical or logical and how many disks make up the NAS SAN or DAS.

Working with 4 disks is not the same as working with 16 disks at the same time and several of these disks are damaged. If it is physical, determine if the failure is of the cabinet itself or if the components (hard disks) have been damaged by use, degradation, defective, etc. In addition, it is necessary to know what type of RAID is used, since there are RAID 0, RAID 5 or RAID 6 among many others.

The complexity of the recovery is determined by imaging the damaged devices (performing the tasks in the lab and clean room) and reassembling the RAID parameters (block size, offsets, parity, etc.).

In many cases, the EXT 3 / 4 file system, XFS or VMFS (virtual systems) add an extra layer of difficulty. On VMFS systems, once the RAID is remounted, the VMFS container may also have to be remounted to display the contents of the virtual machines.

In a logical problem such as a virtual machine or Snapshot deletion, it is very important to stop the NAS, SAN or DAS to avoid overwriting information.

EXT 3 / 4 XFS or VMFS file systems are extremely complex to recover due to their design. They are extremely robust in terms of file corruption, but deleted data recovery processes are not always possible.

Likewise, it is important to note that if the set of disks are SSD the TRIM command can play a determining factor in the process of data non-recovery.

Vehicle Forensic Analysis

What is vehicle systems forensics? It is a process by which a wide range of data and information is extracted from vehicles, which can be used in collision and serious crime investigations. At Laby, we offer specialized services to support our clients in obtaining and analyzing vehicle data. Our team

Mechanical hard disks

HDD disks have as main components the metal plates (disks), where the data is stored, and the heads that are responsible for accessing the information. The most common hard disk.

SSD Hard Drives

SSDs do not move, hence the name solid state. The information is stored in blocks and no headers are required to access it. It is much more efficient and faster than an HDD hard disk.

External Hard Drives

External hard disks allow us to store outside the computer all the important information of which we want to make a backup copy. But one failure can cause us to lose all this data.

iPhone, iPad or MacBook

Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.

Laptop hard disks

On the laptop hard disk we store important work or home information. If a failure occurs, it can cause us to lose all this valuable personal data.

NAS, SAN and DAS disks

A SAN, NAS or DAS disk is a compact enclosure consisting of several hard disks that are connected via a network cable to the system, hence the common name network hard disk.

RAID systems

RAID disks are a redundant group of independent disks. They can be HDD disks or SSD disks and together they form a storage system to distribute or replicate data.

Pendrives and USB Flash Drives

Pen drives or USB flash drives consist of one or more memory blocks. They work in many cases like SSD devices (same Flash technology).

Memory cards

Memory cards are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.

Virus or Ransomware

We recover data encrypted with viruses or ransomware. Ransomware is extortion software: its purpose is to prevent you from using your device until you have paid a ransom. Depending on the type of ransomware, the entire operating system or just some files are encrypted.

Mobile Phones and Tablets

In mobile devices or smartphones or tablets, the recovery processes can be carried out through the analysis of the electronics of the damaged components or, by carrying out the chip off process.

Data deletion

We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.

Computer forensics

Computer forensic analysis and expert evidence. We recover and certify critical information with legal value for companies and individuals. We have collegiate computer experts to carry out certifications, expert analyzes and reports with legal value.
