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:

Macbook Air – Failed Mountain Lion Update

Issue

Client had been using Macbook air which contains some valuable data including some expensive Apps and also photos and vido that cannot be replaced. Problems started when client completed Mountain Lion update on Mac Air and now client cannot boot up laptop. The client receives a question mark and nothing else. Client got the hard drive removed from Mac Air and inserted it into a usb caddy but usb caddy did not recognise the hard drive.

Our Solution

We received the hard drive in and diagnosed that the problem was firmware issues with the hard drive. The firmware code got corrupted and as a result hard drive went into factocy mode and would not boot up. We reflashed the firmware and backed up data for client onto a portable hard drive. We also sent client back the drive as reflashing the hard drive fixed it.

* If you have an Apple Mac with firmware problems we have the largest hard drive firmware database within the UK.

Case Study 2:

Synology DiskStation Disk Platter Damage

Issue

Client was using a Synology DiskStation with 2 x 3TB hard drives. The Synology DiskStation without warning crashed for some unknown reason. The Synology DiskStation is now making a loud screeching noise and sevral beeps. Client switched on and off the Synology DiskStation but same screeching and beeping noises. The noise seemed to be coming from one of the hard drives so client removed the hard drive making the noises and replaced it with a new disk. The Synology DiskStation did not boot up but at least the noises stopped.

Our Solution

We received in the Synology DiskStation and diagnosed that the system was a Raid 0 system. One of the raid 0 hard drives had a mechanical failure. There was a failure of the read/write heads and also some minor media damage on the disk platter surface. We recommedned a platter swap procedure and imaged 98% of the sectors. We processed the Raid 0 system and extract 98% of the data.

Case Study 3:

HP Proliant 370 Server – No Hot Spare

Issue

Client was using the HP Proliant 370 Server as the main storgae server on their company network. The raid array consisted of 5 sas 300gb drives. The client is a large finance company so the server was used by all their European offices to store everyday business data. One if the hard drive’s failed without warning, the hot spare on raid array kicked in and rebuilt the server. Server worked fine for 4 months until another disk failed in the raid array. Unfortunately the client forgot to replace the hot spare and thus the drive had no redundancy.

Our Solution

We received in the 5 sas drives from the HP server and imaged all the working drives and put them back in their box. We diagnosed that the failed disk has a common seagate sas firmware failure and thus upgraded the firmware code on the drive so that we could image the failed disk. We need imaged the disk and processed all data from the HP server.
