How to recover data from NAS Buffalo TeraStation WSH5610DN12S6

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Buffalo also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Questions and answers

  • What is iSCSI and how does it work?

    iSCSI, which stands for Internet Small Computer System Interface, is a protocol that allows the transmission of SCSI (Small Computer System Interface) commands over IP networks. It enables the connection of storage devices over a network, typically Ethernet, to provide block-level access to storage resources.

    Here is how iSCSI works:

    1. Initiator: The initiator is a client device that initiates the communication and sends SCSI commands to the target device. It could be a server, workstation, or any device requiring access to storage.
    2. Target: The target is a storage device that responds to the initiator's requests. It could be a disk array, a storage server, or any device that provides storage resources.
    3. iSCSI Protocol: The iSCSI protocol encapsulates SCSI commands within IP packets, allowing them to be transmitted over IP networks. It uses TCP/IP as the underlying transport protocol, ensuring reliable and ordered delivery of data.
    4. Discovery: Before communication can occur, the initiator needs to discover available targets on the network. This is typically done using the iSCSI discovery process, where the initiator sends a discovery request to a well-known IP address or broadcasts it on the network. The target responds with its available storage resources.
    5. Login: Once the target is discovered, the initiator establishes a session by logging in to the target. This involves authentication and negotiation of parameters such as security settings, session-level parameters, and target-specific information.
    6. Data Transfer: After successful login, the initiator can start sending SCSI commands to the target. These commands include read, write, and other storage-related operations. The iSCSI protocol handles the encapsulation of SCSI commands into IP packets and their transmission over the network.
    7. Data Integrity: iSCSI ensures data integrity by using CRC (Cyclic Redundancy Check) to detect and correct errors during transmission. It also supports other mechanisms like IPsec for encryption and CHAP (Challenge-Handshake Authentication Protocol) for authentication.
    8. Session Termination: When the communication is complete, the initiator can terminate the session by logging out from the target. This releases the resources and ends the connection.

    Overall, iSCSI provides a flexible and cost-effective way to access storage resources over a network, allowing organizations to centralize storage, improve data management, and simplify storage administration.

  • What are the benefits of using iSCSI in a network storage environment?

    There are several benefits of using iSCSI in a network storage environment:

    1. Cost-effective: iSCSI utilizes existing Ethernet infrastructure, eliminating the need for expensive Fibre Channel (FC) switches and adapters. This makes it a more affordable option for small to medium-sized businesses.
    2. Scalability: iSCSI allows for easy scalability by leveraging Ethernet switches and routers. It can support a large number of devices and can be easily expanded as storage needs grow.
    3. Flexibility: iSCSI can be used with both IP networks and Fibre Channel networks, providing flexibility in choosing the infrastructure. It can also be used in both local area networks (LANs) and wide area networks (WANs), enabling remote storage access.
    4. Performance: iSCSI provides high-performance data transfers over Ethernet networks. It supports multiple network paths, load balancing, and jumbo frames, which can significantly improve data transfer speeds.
    5. Centralized management: iSCSI allows for centralized management of storage resources. Administrators can manage and allocate storage from a single console, simplifying storage management tasks.
    6. Data protection: iSCSI supports various data protection features such as snapshots, replication, and backup. It enables efficient data protection and disaster recovery strategies.
    7. Compatibility: iSCSI is compatible with various operating systems, including Windows, Linux, and macOS. It can be easily integrated into existing IT environments without major disruptions.
    8. Virtualization support: iSCSI is widely used in virtualized environments, as it provides efficient storage provisioning and management for virtual machines.

    Overall, iSCSI offers a cost-effective, scalable, and flexible solution for network storage environments, providing high performance and simplified management of storage resources.
