3.12.9 Added an article regarding the possible future developments in data storage technology and techniques.

>> Data Recovery News - September 2009

14.9.9: We are having some success in data recovery from SSD hard disks. [These disks store their data in memory chips rather than the more conventional rotating platter(s) and read / write heads. Because of this, most exisiting data recovery techniques are not applicable and can not be used.] The success is due to the development of new methods and techniques in accessing and organising the data once it has been read from the individual memory chips.

>> Data Recovery News - August 2009

5.8.9: Added a page on recovering data from hard drives with seized spindles. Due to equipment purchased, we are now able to offer a near 100% success rate on drives with this type of fault.

>> Data Recovery News - July 2009

9.7.9: Once again we recover a Snap Server RAID array that another data recovery company could not. Snap Servers can be difficult to recover because of the customised file systems they often use. In this case we had to write some custom code to emulate the workings of the server's filesystem. As far as we know, we are the only UK company who can recover these devices, this is primarily due to the calibre of staff we employ. Recovering data from Snap Server RAID arrays.

16.7.9: Added a PDF that summarises our RAID data recovery services

23.7.9: It seems that some of the Seagate Momentus 7200.3 drives have the 7200.11 firmware problem too - page updated.

30.7.9: Another high profile job completed. This one was a RAID for Celtic Football Club.

4.6.9: Added a page about Data recovery from Western Digital GreenPower hard disk drives
17.6.9: Our investment in quality staff leads to us offering our superb SQL data recovery service

>> Data Recovery News - March 2009

10.2.9: Added a page about Western Digital drives that produce WDC ROM MODEL error messages
10.2.9: Over the years we have seen quite a few high profile jobs. Last month we recovered a hard drive belonging to a UK band who, I think it's fair to say, would currently be ranked as the biggest rock band in the world. Unfortunately we can't say anything else about it, due to Non-Disclosure. This month, we have recovered a drive belonging to the BBC containing video footage that will be broadcast during this year's Comic Relief telethon. Data Clinic recover disk drive for BBC Comic Relief.

12.11.8: New page added - How to identify electronics faults / failures / problems on Seagate Barracuda hard drives

+ Data Clinic are now able to recover data from ALL models of IBM / Hitachi drive with service area damage. This type of fault on IBM/Hitachi disks previously meant that the data was unrecoverable.

The Limitations of Magnetic Recording

The areal density of magnetic recording has increased hugely since its inception in the early 1950s, despite technical obstacles that have at times seemed to spell the end for this type of data recording.

Hard disk drives currently operate at data rates of 30 Mbyte/s and have areal densities of 5 Gbit/in (squared) but in only four or five years could increase to 100 Mbyte/s and 40 Gbit/in (squared) respectively.

Doubling areal density is achieved by reducing other dimensions, such as track width, head gap, medium grain size, medium thickness and magnetic spacing, by a square root of two. This process lessens the strength of the signal amplitude and therefore greater read head sensitivity (eg. MR and GMR heads) is required. While during the 1970s it was considered impossible to achieve the low flying heights required, new head slider designs and disk polishing techniques have made current flying heights of 20-30 nm a reality.

It is believed however that conventional magnetic recording cannot continue to increase indefinitely; the thermal stability of written bits and magnetic grain size will ultimately limit growth. In addition, the magnetic materials of the head and the write electronics should prove to be technical obstacles to achieving increases in recording speed.

Welcome to 2008 - A Happy New Year to everyone !

What will 2008 bring ?

10.1.8: I've just added an information page and some pictures about hard disks that develop motor faults. We believe the problem is related to the drive's fluid dynamic bearing - we were the first company to annouce this could cause problems back in 2004/5.
