Buffalo Terastation & iSCSI NAS RAID Data Recovery



The Buffalo TeraStation can be pedestal or Rack mounted and include 4 bay quick-swap SATA hard drives, Gigabit Ethernet connection, Built-in FTP server. Common Raid levels supported are RAID-0, RAID-1, RAID-5, RAID-10, JBOD.
The more recent versions offer their hard drives as iSCSI LUN's or Virtual Volumes and these are finding their way in to small businesses as low cost way to host Virtual Machines. We have recovered a large variety of implementations including VMware Virtal Machine File Systems VMFS, NTFS partitions, Microsoft iSCSI initiator, ESX servers and workstations, Citrix Xenserver Virtual Machines.

Problems with the Buffalo unit can usually be seen in the web based configuration control panel screens. Also with the later models an LED/LCD display shows error code and warnings. Problems we have recovered data from include accidental re-formatting the disks, lost data access, accidental deleted share folders, formatted drive, raid error or lost raid configurations as well as the Teratstaion being stuck in a continual Raid Re-Build cycle which never seems to end!

In rack mounted iSCSI Terastation versions we often see that the firmware does not boot up correctly but instead enters Emergency Mode – EM482. Buffalo often advise to update the firmware but the system still boots into Emergency Mode – EM482 even with the Debug options. Buffalo then usually advise the next step is to rebuild the partitions and therefore destroy the data. Before you get anywhere near this option we suggest you contact a data recovery expert to secure your data. We can usually do this within 2 days so contact us using email/phone at the top of this page.




Buffalo Terastation Pro II Data Recovery
Data recovery including error in a RAID Array with 4 flashing/blinking red led lights, or SATA hard drive failure. Another common fault is the Chip Error E21 Ethernet Failure - see further down this page for a list of error codes. We have also recovered files when Share folders have been deleted and accidental re-initialising re-format of the drive.

Among other things, we can recover data when the terastation has lost the SHARE folder or have a burning smell / burnt pcb, accidental formatting. After powering the device back up,sometimes it sounds an audible alarm, beeping/ beep sound, and the red LED light indicated a disk failure Error. Typical examples include Terastation beeping with a red light on the panel - showing "WDT E05 SYSTEM STOPPED"
