Case Studies

We have helped a wide range of clients over the last 15 years and reasons as to the whys and wherefores of the loss of their data. To that end we have a broad knowledge of problems relating to data recovery as our case studies show.
Case Studies

Case Study 1:

Iomega 2TB NAS Drive

Issue

Iomega 2TB NAS Drive stopped working without any prior warning. Client removed the HDD from the Iomega NAS casing and connect the hard disk directly to my PC. HDD was now connected to PC and was spinning healthily, but HDD was only intermittently visible in CMOS at boot – at times the HDD was visible and at other times it was not visible in CMOS. HDD was only intermittently visible in Windows Device Manager. Client had a mixture of movies, music and photos stored on the Iomega NAS Drive.

Our Solution

We received in the Iomega drive and quickly diagnosed that the Iomega system was two disk raid 0 system. One of the disks in the raid 0 configuration had electronic and HDD Firmware issues. We upgraded the Iomega electronics on HDD and flashed new firmware to hard disk. We then was able to image all sectors on HDD and backed up data to another external HDD.

* We work with all NAS External Hard Drive Systems including Iomega, Lacie, Buffalo, Synology, Seagate, WD etc.

Case Study 2:

Lacie 2big Network Raid 1 System

Issue

Lacie 2big network set to Raid 1. A Raid 1 system means there is two disks inside the Lacie casing that had an identical copy of the data on each disk. Photoshop crashed one day while using the Lacie 2big system and the client could not access most of the files on the Lacie system. Something happened during the crash, some files have moved location, other folders have been renamed, most folders are invisible and the speed of the system is very very slow. When client tried to copy data to Lacie 2big system it took 10 minutes to copy a 10mb graphics file. Client tried different disk utilities to try and repair the file structure on the NAS system but no go.

Our Solution

Disks have degraded on Lacie 2Big external drive system. We removed 2 disks and diagnosed each disk. The two disks had millions of bad sectors, and one of the disks had an out of date dataset so could not be used for the recovery process. We imaged the disk that had an up-to-date dataset on a hardware imaging system we have for force reading bad sectors and produced a 100% image of hard drive. We then processed the raid 1 system and backed up data to a Seagate portable hard drive.

* We specialise in recovering data from Raid based systems.

Case Study 3:

MacBook only booting up to question mark symbol

Issue

Client had a 3 year old Macbook Pro running the Snow Leopard operating system. When they booted up the Macbook they received a flashing folder with a question mark on a grey screen. Client took Macbook to Mac Store to get them to look at Macbook but they could not recover the data. The Mac Store recommended ourselves to recover the data.

Our Solution

A flashing question mark on an iMac, Macbook, Mac Air means the operating system software cannot be read correctly. If running startup disk or taking it to Mac Store does not resolve the problem then it normally means the hard disk has a software/electronic or mechanical fault. We diagnosed the Macbook disk and confirmed the hard disk had a faulty read write head assembly. It turns out the Laptop was dropped. We upgraded the motor on hard disk and imaged all sectors on disk. We backed up data on 5 data dvd’s for client.

* We offer that good a service that Apple stores across the UK recommend us to their clients!
