What are data recovery services?

August 19th, 2010

The search term data recovery services in Google will list over 55 million results with websites offering software, DIY advice to actual data recovery services provided by a professional lab with years of experience, however how do you select the right lab to deal with, surely the only factor really to take notice of are the costs right?, wrong and here’s why.

Many data retrieval websites are either ressellers for larger labs or simply operate from a home address or a rented office they do not have an actual clean room facility just a fancy website to hook unsuspecting clients in with, oh and one last clincher is the VERY low price offered for the service.

Clean rooms are based on laminar flow cabinets which contain a pre-filter and main filter, these filters cost considerable sums and the time for an engineer to attend on site to install and calibrate the cabinet to spec, this has to achieved on a regular basis.

Engineers, particularly good data recovery engineers are not readily available nor are they inexpensive as they often have years of knowledge they have built following 1000′s of recoveries both of logical or physical types.

Testimonials is a good area to consider, after all the client type may speak volumes such as MoD, or large corporations, however if those testimonials are on their website of what value are they really, could not they simply be made up? Independent websites which offer testimonials offer or give impartial advice about the service they have received from company x for instance really can help you make a more informed choice, also there may be examples of a similar situation or hard drive which was dealt with successfully, proving the company is capable of performing such work on your media.

Competitor bashing is highly unprofessional and should be avoided, surely it is best for a companies results and track record should speak for itself? Competition in any sector is obviously good for may reasons and should be welcomed, however if a company continually attacks other companies and praises there own, is this a bit passe or old hat? Why after all should they praise their competitors, a mere recognition that a potential client has mentioned them and requests your feedback about them should be along the lines of acknowledgement only and to pass no negative or potentially damaging comments which are untrue.

How may data recovery companies are there in the UK alone?
Well at the last count there appeared to be over 50 companies offering data recovery services of one type or another, however in reality this is easily narrowed down to 10 or less with clean room facilities and a decent track record, perhaps a visit to companies house will show exactly how long the company has been running, a lot less that the 15-30 years some state, this should serve as a warning.

Speak to friends and colleagues and find out if they have ever required hard drive recovery and if so who did they use and was it successful?

Once you have selected a company check to see if they are members of any organization or trade body, this could further serve as help to make your choice.

Why all the rigmarole you may ask, after all if one company fails to recover my data surely I can send it elsewhere, like plan B? Yes you can send to other labs for a second opinion, however with every potential recovery and opening of the media via different labs the chances of recovery diminish, sometimes a hard drive may have a finite time of existence, particularly if there has been serious media damage following a head crash and the magnetic domains are now failing.

Could you live without your digital world or hard drive?

August 18th, 2010

A report today from the USA has stated that certain individuals could rid themselves of all personal physical possession save for their digital assets like Ipods, Ipads, hard drives and other such type of devices.

These storage devices obviously contain such data is iTunes, movies and pictures to name a few, basically your digital life so to speak, but could you do without them, or More’s the point just live with them alone and sell all other possessions?
Seems extreme but people really are doing this, OK there are some items that we will need in addition such as a bed, roof over our head, food, clothes, but gone are other extraneous or superfluous items such as ornaments, trinkets general clutter, I for one think this digital minimalism is a good idea and does not bog you down with other such details as buying the latest this or that even for digital items, what is the point of upgrading every time a new upgrade or model comes along? OK there are exceptions to this rule, but if it is not broken don’t fix it mentality surely with a minimalist attitude has to be good for you, especially your pocket in these difficult financial times we live in.

There is obviously one serious caveat to this, backup your data! You may have little or live out of a rucksack so to speak, but make sure you have a decent and reliable backup not just for your hard drive or disks but all other devices such as phones etc.

Seriously though how can modern society function without it’s digital counterpart? Think if you lost your phone and Internet for 24 hrs, how would that effect you? What about if you lost them for a month? I am sure this would cause at the least a major disruption in your life or worse.

How really did we get to this enlightened stage where we all rely so heavily on gadgets or technology? It appears to have crept up on us by stealth, sure PCs were about 10 years ago so was the net, but not to the level we see today, many see the advancement of technology as a good thing, and it has to be said that the Internet really has helped in so many ways we never even thought of previously, take the dissemination of knowledge its instant on demand and can be converted at the touch of a button from virtually any language to your own native tongue, this speed has helped in collaborative projects such as medicine and health care, much needed help and understanding has and is achieved.

The 24 hr digital world is constant, available and on demand to all, and to date has never failed, what would happen if the internet failed? Surely this is not possible? Or is it? Then we have the various mobile phone networks supported by satelites, again what if they were to fail?

Studies have shown that not only are there the obvious terrorist threats to various networks there may also be a threat which is out of our control, that threat is from the Sun.
It is well documented that the sun has various cycles, such as sporadic E, additional to this there are krona mass ejections, these solar winds and high energy particles are ‘dealt’ with via the poles here on earth, however as most of the infrastructure is based in stationery or geostationary orbit(s) around the earth and outside the protection of earth they are very vulnerable to such high energy events and could in theory be ‘knocked’ out or damaged, depending when and where the solar stream came from the effects could be devastating to networks here on earth.

Of course scientist do  factor into their equations such events and have rudimentary systems such as Faraday cages and other such type systems and subsystems for protection, usually there are also secondary satellites that can be brought online, so its not all doom and gloom, if anything form this blog consider your digital assets and how safely you store them against any possible data loss.

Toshiba self deleting hard drive

August 16th, 2010

Toshiba have announced a self deleting hard disk for the convenience of destroying user data prior to the disposal sale or however you may to deal with the storage device at end of life or usefulness to you as a user.

Many users may have to invest in software or a service to securely destroy any data that may be remaining on the hard disk, also there can be a further resource of time such as setting up and configuring the data destruction application, so having this facility ready to go out of the box is very handy indeed, although this is intended for high security environments and probably not aimed at the consumer end of the market.

It is also reported that the technology will used in larger disks for desktop PCs and even printers and copiers.

1Tbit/in2 nanosphere platters

July 15th, 2010

Researchers are reportedly working on 1Tbit/in2 nanosphere platters, this storage capacity would increase hard disk storage to truly spectacular levels of storage the like of which never even dreamed of just a few short years ago.

All information and news regarding this research can be found here;

http://www.teramagstor.eu/

Working on the nanometre range the nanospheres are evenly set up across the disk surface or media based on silica substrate production costs of this type of technology is believed to be lower.

Current research also shows evidence that the areal density could also be increased six fold.

As a European venture this technology would be very welcome as of now there are no large scale manufactures of hard disk drive from the EU, although certain sputtering technology is available.

The system is based on an entirely new concept in that it creates ‘zones’ or magnetic ‘domains’ which do not interfere with adjacent or closely neighbourhood other areas.

Watch this space for new developments and news on this exciting new technology.

Fast, reliable hard drive Western Digital WD6000HLHX

July 12th, 2010

If you think that spinning magnetic media aka hard drives or disks to me and you are dead and SSD or solid state drives are taking over, think again.

The Western Digital Wd600HLHX hard drive is absolutely amazing.

Here are some the specs of this drive;

10,000RPM, 32MB cache, SATA 6G/bs, 1.4 million mtbf mean time between failure, 5 year warranty, read seek times 3.6 ms and write seek time 4.2 (avg), a truly stunning piece of kit for any gamer or performance system, pair these up or better still configure into a RAID 5 configuration you have a decent data protection and file server setup with very fast read and write access times.

Cooling of the drives is catered for by a inbuilt heat sink and offers rack mount back plane for extra colling of the hard drive.

Capacity is now doubled from the 300gb previous model and offers a decent storage size for users that require more room for their digital archive of music, photo’s and the like.

How many hard drives come with a 5 year warranty these days? Not many, in fact it wasn’t all that long ago many manufactures supplied 3 and 5 year warranty, however there appeared to be a shift back to 12 month warranty not so many years back, so this hard drive shows confidence and reliability from the manufacture in the long term performance of this drive, they represent a very good ROI for your data, after all how would you recover if your hard drive failed and you did not have any backup at all? Perhaps data recovery has been attempted and failed, you are left with nothing, no data.

Sony Vaio to be re-called RE: over heating issues

June 30th, 2010

Sony has reportedly requested the voluntary return of VPCF11 Series and VPCCW2 Series laptop computer systems which may overheat, and in some reports have deformed the case and keyboard, further reports suggest that in extreme circumstances it may be able to hot to handle.

The fault is thought to be with the software which controls the temperature and cooling of the Sony notebooks, a firmware upgrade has also been announced to help users deal with this particular issue.

Cooling for a notebook or laptop is more important than you might obviously realize, as clearly the CPU has a major requirement here as it gets very hot due to switching in GHz range, another area for temperature control which has little attention from all manufacturers is the cooling for the hard disk drive, clearly there are issues with laptops, notebooks netbooks and creating ever smaller footprints, this creates design issues and logistical problems, exactly how and where do you cool a 2.5″ laptop or smaller media in such a confined space?
One answer is to buy a laptop cooling kit, and they do exactly as they state, basically they are comprised of a naicely shaped piece of metal with one or two fans, the laptop or notebook sits on top of this and creates an air gap for air to circulate and blow cool air onto the hard drive and the battery compartment, this helps keep the computer running at opttimum temperature which helps prolong the life of the hard drive and preserve your data integrity.

Firmware SA Virus utilizing ATA commands unstoppable

June 30th, 2010

All computer users are all to aware of malware or virus type payloads delivered to cause any thing from mild annoyance to more serious forms of destruction like the loss of data, hidden partitions and the like.
All antivirus and antimalware software companies work on a 24 hr basis from all corners of the globe to combat this ongoing threat, as this number has past over 1000,000 that’s right one 1 million.
One of the most insidious types of malware is the root kit, root kit malware can be a hardware or more often software system which is able to get control of kernel or high level services without being detected.

Most types of malware are dealt  with via those good guys out there from the antimalware companies such as Norton, AVG, McAfee, TrenMicro and others to name a few, there is one area to my knowledge that is completely unreported or being actively researched, what exactly could this be? Well it is do with the way hard drives and disks operate at a very low level and is an area most computer suers are aware of, the system is ATA commands which are part dealt with via the vendor specific commands made via the manufacturer and also the T13.org group which chairs and build the structure of the committee.
ATA commands are locked away from all users and as such are ‘hidden’, the closest you may encounter this system is if you’re hard drive has a S.M.A.R.T issue, this is a small part of the firmware and a very basic diagnostic routine based on re-allocated sector counts and other possible tables of bad sectors.
Utilizing specific techno and vendor specific commands access to this very vital area is possible and indeed utilized by data recovery technicians worldwide to help restore and recover data on a daily basis.
Some of the functions of the firmware or SA are to deal with what is called the P-List or factor list, this table contains very important information for the surface of the disk and where all the bad sectors are at the creation point of the hard drive process, this P-List also works with what is called the translator which can be either static or dynamic in nature, this translator deals with physical to logical location of sectors and is classed as ‘A’ as in terms of importance, if it is destroyed your data, even though intact on your hard drive will become unrecoverable.

As of yet we are uncertain as to whether any virus or malware has been devloped that once tha payload or root kit has been deployed the P-list or translator is destroyed, thus rendering your hard drive broken and more importantly your data unrecoverable.

We would like to discuss with any anti virus / malware software company what if any research they have undertaken in this area and if they would like to work on a  collaborative effort to deal with this very serious issue, if developed and deployed on a worldwide basis the effects would be devastating.

Advice to avoid any issues at all are as always, update your antivirus daily, run at least one weekly full scans of all drives including network attached storage, defrag your hard drive at least once a month, never open emails you do not know who the sender is, or at the least place in your spam filter, delete immediately all deleted emails, anything suspicious should be quarantined or send the file(s) to your software provider.

3TB Seagate hard drive?

June 29th, 2010

So Seagate are now reportedly shipping the massive 3Tb hard drive.
The storage device is called FreeAgent GoFlex Desk External Drive 3Tb, and stores a whopping 3Tb (before factory formatting etc) and pushes the envelope further for storage hungry users who demand more and more digital space for there computer requirements.

On sale for a reported $250 it offers excellent ROI for hard drive storage users, however there were technical difficulties in areas that most users would not even think of, namely the file system of XP and earlier products which has a limit of 2.2 Tb, and the sector size of 512 Byte, the fix is based around increasing to 4k sector size , other issues are LBA (Logical Block Addressing) and the new LLBA (Long Logical Block Addressing) which extends this now outdated format, who would have thought that all those years back that we would ever need to go beyond 2.2 Tb on a  single volume?

Boasting 5 platters at 600Gb per platter and utilizing a technology called SmartAlign the areal density has not been increased.

So what can you store on 3Tb hard drive? Right now figures are not available but simple maths using MP3 files of 4Mb on average file size give colossal figures, perhaps you can use this device for digital photography purposes and store all of your precious memories of loved ones, then there is the RAID aspect, 5 x 3Tb in a RAID 5 configuration, now there’s a thought!
The list of the uses of this magnificent device is truly endless.

One last thought on this subject, ‘what next for storage’ I mean when will we be saying ‘only 3Tb hard drive’? Mores the point what exactly is the raodmap for spinning magnetic media or hard drives to me and you, well rest assured areal density and total storage area on single 3.5″ media is set to continue, at least until the foreseeable future, watch this space as they say.
