WHAT ARE THE NAS, SAN OR DAS?
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.
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.
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.
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.
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.
PROBLEMS WITH A 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.
TIPS TO NOT LOSE DATA
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.

HOW MUCH DOES DATA RECOVERY COST
FROM A NAS, SAN OR DAS DEVICE?
PRICES FOR DATA RECOVERY FROM NAS, SAN OR DAS HARD DRIVES
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:
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.
For Firmware faults:
- SW internal disk corrupted. Damaged modules.
For engine breakdowns:
- Over temperature or motor unit failure.
For head failures:
- Surface degradation or reader unit failure.
If it is a set of disks
For logic or electronic board faults:
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.

WHICH DEVICES CAN WE RECOVER IN LABY?
Mechanical hard disks
HDD disks have as main components the metal plates (discs), where the data is stored, and the heads that are in charge of being able to access the information. The most common hard drive.
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 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 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 such as smartphones or tablets, the recovery process can be performed through electronic repair of the damaged components or by performing the chip off process.
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
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.
