Buffalo servers and storage systems are among the most popular ways to keep data. The LinkStation and TeraStation series are top-rated for their flexible choice of rack and modular enclosures. Buffalo servers are RAID capable, so most companies configure these servers with RAID 5.
Redundant Array of Independent Disks provides essential protection against data loss. Still, the system can fail after re-striping errors, accidental deletion of a logical partition, mechanical failures, and other adverse events. These problems are detected by error messages on the LCD screen or beeping sounds in most situations. Still, each server is different, and failure scenarios may be different.
No attempt should be made to rebuild or reinitialize the array in this situation. Admins should pay attention to any messages on the device’s LCD, BIOS error messages, and symptoms of mechanical problems. If there are failure notifications, they should immediately contact data recovery specialists. It is also essential not to run recovery programs or disk utilities as they can overwrite lost data which will make data recovery impossible.
Buffalo NAS Data Recovery
The NAS data storage networks are more beneficial than traditional backup devices. The first and most crucial problem is that, in most cases, the tape device is connected to a single host, which must directly manage the backup operations and transfer data for that purpose.
Thus, the information to be recorded on the tape must be transmitted to that host over the local network, which severely limits the backup speed and inefficiently consumes server and LAN resources.
From the server’s standpoint performing the backup operations, the inefficiency lies in the fact that it is an intermediate point on the data path, which is repeatedly forwarded through its system memory. Implementing a NAS provides businesses with rational use of disk space.
Choosing the wrong disk drives can quickly ruin any good NAS. Essential parameters of disk drives for network-attached storage are volume, spindle speed, and access time. If the only issue with disk space is how to use it properly, then spindle speed and access time affect system performance to a much greater extent.
Buffalo NAS File System Failure
Recently, we received a Buffalo NAS LinkStation device for a data recovery procedure. The client consulted with our dedicated customer service and decided to proceed with our emergency recovery services. In this option, the turnaround time is within the 8-48 hour range.
The customer shipped his device to our laboratory. As soon as we received the network-attached storage, our engineers ran diagnostics to find the problem. The device did not respond and was not seen in the BIOS.
Then we carefully inspected each drive in an ISO Certified Class 10 Cleanroom. The inspection showed that the spindle motor of one of the hard drives failed. As one of the HDDs failed, the file system of the entire area network failed as well.
The spindle motor is an essential component of a computer hard disk drive, which is responsible for rotating the plates of the drive on the axis.
Accountable for the uniformity and stability of rotation, the spindle provides trouble-free operation of the hard disk.
The wedge of the bearing is often complicated because the spindle motor’s control chip, trying to spin the motor, experiences increased loads, heats up more, and usually burns out. Replacing the electronic board with a serviceable one, in this case, can lead to the fact that another microcircuit will burn out.
Buffalo NAS Hard Drive Data Recovery
To recover information from such a hard drive, we needed a donor hard drive to which platters from a broken HDD are transferred. The procedure was not easy, requiring special equipment for the subsequent centering of the plates since any micro-displacement along the axis can lead to the fact that the heads cannot be positioned correctly according to the servo markings.
After replacing the spindle motor, our engineers transferred the data to a new hard disk drive. The next step was to restore the RAID array and repair the file system.
We used our cutting-edge data recovery tools to emulate the RAID controller and restore the array. Then the file system was recovered, and the server started operating again. The client reviewed all the processes and received 98% of the files.
