Have one of these? Seagate BlackArmor NAS 220 RAID 1 Data Recovery Salem MA 09170

Client's drive was a Seagate BlackArmor NAS 220 drive that no longer allowed access to the files. He stated the “NAS is no longer visible on network or computer”.

Our staff picked the drive up from the client's business site.

Inside the Seagate BlackArmor NAS 220 drive enclosure there were two SATA hard disk drives:

 

Drive 1:

2TB Seagate Barracuda Green

MDL: ST2000LD003

SN: 5YDXXXXX

PN: 9VT166-575

FW: CC3C

Drive 2:

2TB Seagate Barracuda Green

MDL: ST2000LD003

SN: 5YDXXXXX

PN: 9VT166-575

FW: CC3C

Failures: Drive 1 sustained severe firmware failure as result of media degradation causing bad sectors in the system area of the drive, while drive 1 sustained logical corruption on the ext3/4 volume containing the data. Based on a chronological failure interpretation of the state the drives were found in, along with file date stamps on drive 2, drive 1 failed a long time prior to drive 2. Warning here is ,that in most drive failure circumstances, the NAS management software running the NAS box does not notify the user of the HDD failure, thus providing a chance for HDD replacement and RAIDarray rebuilding to take place.

Here is a snapshot of the firmware failure on drive 1:

Seagate Green Barracuda Firmware Failure

Solution: The technicians created a byte level clone of drive 1 to a healthy Seagate Freeplay external drive using advanced data recovery hardware based equipment. Upon completing the hdd cloning process, the ext3/4 volume had to be analyzed with special advanced software that would allow correct interpretation of the corrupt superblock structure. Once the volume’s logical parameters have been corrected, the volume were mounted and files were made accessible. Next, the files were extracted to a brand new 32GB Sandisk USB 3.0 flash drive formatted to FAT32. File listing was provided to the customer for review. Upon client’s review confirmation, the recovered data content on the USB flash drive were delivered to the customer.

Outcome: Customer shook our hand stating "You guys did a fabulous job. Thank you."

Cost: $419 for 24 hours service.

Recommendation: If your NAS device no longer allows access to the files, please consult with a data recovery expert. Typically, NAS devices employ non-traditional file systems which regular software tools do not support. Any additional stress from software partition/volume scanning, especially on degraded drives with bad sectors in the firmware and user areas, will more than likely reduce the chances of successful recovery and increase the data recovery cost.
