Hard Drive Issues and a Phone Problem

Friday, November 25th, 2016

I have issues with 2 drives. Segate external plug in, started clicking and now wont boot up. Second drive cable connection is very loose and i cant get that to boot up either. My external hard drive does not display data when connected to laptop.

Seagate hard driveIt’s data recovery from a Laptop, ASUS G551TW-CN080H-16GB. It’s a logical failure, rather than a physical drive problem.
The Laptop developed a problem with the power where it would not hold a charge and ran until it had no power left. As it was under warranty it was sent back to ASUS for repair. However they replaced the mainboard and recovered the operating system without backing up the files on the laptop, or reinstating the file index/table.

The laptop came with the hard drive partitioned as; C drive – for system files, D drive – for file storage, E drive – for file storage. The hard drive wasn’t replaced when the laptop was sent away for repair, and came back with the same partition configuration as above.
The hard drive is a 1 TB HDD / 7200rpm – SATA 6 Gb/s.

The files I want to recover were mostly on the D drive, with some on the E. The most important file types are video and photo, .avi, mp4, mts, mov, and jpg.
Data recovery software has been run on the machine once, and a lot of the photo’s and some of the video’s recovered. There are still a lot of video files which were not recovered.

I made a factory data reset on my Sony smartphone, and all my photos and contacts have been deleted.

London Data Recovery

Monday, November 21st, 2016

Here’s a question that came into us asking about the services of hard drive specialists Data Clinic Ltd. It sounds to us like the folks at this diy data recovery site may be able to help too, but if you want to use Data Clinic, their London address is on Lombard Street – EC3V 9LJ

Hello i’m a student living in London.
- I have a Seagate 1tb external hard drive which broke on the 12th of November.
– The light on my hard drive does not turn on.
– The hard drive isn’t recognized so therefore I can not access my files.
– When I connect it to my computer through usb it clicks for about 40 seconds and stops making any noise altogether.
-There isn’t a huge amount on the hard drive but it is of great value to me.
I am a student and I am working full time. I really am on a budget. I would like to think that this is a small job for ‘dataclinic’. If you could quote me the probable price and recovery time, that would be great.

I am looking for donor drive WD10SPCX (or just heads), do you have any? How much does is cost?

Our advice is to stay away from buying hard drives of the same model for data recovery purposes unless you are sure you know what you are doing. If fixing a busted hard drive by buying the same model and swapping the control board was all you had to do there wouldn’t be data recovery companies. So be careful as you’ll be wasting a lot of money.

The costs of data recovery can vary considerably depending on the type of drive – don’t forget there are SSD’s as well as HDD’s now!, and the fault with it – data problems, unresponsive drives, dead drives, noisy ‘clicking’ drives are all different faults that are fixed differently and varying in cost.

Computing Problems – November 2016

Tuesday, November 8th, 2016

My Sony Vaio laptop turns on saying the hard disk/drive was not detected. I do not know why as last time I used it worked perfectly fine. Please get in touch asap via email. I am free on Monday 31st so I can drop it then.

Seagate "Backup Plus" drivesI have an iPhone that is stuck on the Apple logo and won’t reboot or enter recovery mode so as to allow recovery of files. It is an iPhone 4S. I live in Switzerland. Do you offer a service whereby I could send the unit to you (Fedex) for you to do a diagnostic test? If so, could you send me a list of prices, or at least the price for a diagnostic test.
In this case, I’d be seeking to recover the photo files and the voice memorandum file in the iPhone dictaphone utility.

A seagate external hard drive is not responding when connected. Need to recover the data in the hard drive. Could you please give me a quote for this service. I am based in London.

About 27gb of photos and videos lost, from Europe trip between April and June 2016, stored on microsd card within Motorola G3 phone. Event occurrence in end June: Dropped the Android phone from bedside table height while connected for charging, and connected to wifi, onto soft carpeted floor. Microsd card malfunction possibly due to potential unseen/unaccepted Android system update, possibly initiated by being connected to wifi after a long time, or by the drop with charge (causing a potential short circuit).

I have a Toshiba External hard drive which doesn’t seem to be working, it turns on but doesn’t boot properly or appear on my computer. I’ve tried different power cables and USB cables but they don’t work. It usually makes a fast clicking noise and the light on the front turns blue but it’s staying red and not making the noise any more. Any ideas what’s happened? I haven’t dropped it or.moved it at all it just suddenly started doing his.

Clicking noise, spins up then shuts down. not detected in system bios.

Questions about Broken Hard Drives

Friday, September 23rd, 2016

In this post we look at three example hard drive problems and give recommendations on identifying the problem and applying the solution to extract the data from the hard drive.

Is Hard Drive Repair Worth It ?
My external hard drive is clicking and not connecting to my macbook so I know it is broken, I do not want a data recovery if possible to avoid it as I’m just wanting the hard drive fixed. I am wondering if you’s fix external hard drives? Thank you.

It’s not really financially worth fixing a hard drive. As hard drives are so cheap to buy, it works out more expensive to fix them than it would be to buy a brand new one. So, if you don’t need to data recovering from your busted hard drive, just buy a new one instead. You’ll get a warranty with it too.

Hard Drive Not Being Found
I have a Seagate 1gb usb hard drive. The light is still lit up when connected to computer, I have brought a new lead just in case it was that, unfortunately it is not being found on any computer. What do I need to do to get the drive to work?

Buying a new lead was a good idea as sometimes that’s all the problem is. Now that you’ve done that and eliminated the lead it’s worth eliminating the external case. Remove the hard drive from the casing and hook it us directly to your computer using a USB to SATA cable. If that works then obviously the case is at fault. If the hard drive is still not being found then the conclusion is that there is a fault on the hard drive. There are some things you can do yourself to try and repaid your hard drive – go and take a look at the http://www.recover-deleted-data.co.uk/ web resource for some good tips of getting the information of off broken hard drives.

Getting the Data off a Packard Bell
I would like quote for the cost of recovering data off a Packard Bell Store & Save hard disk drive Model No H2D2U2 6948820100, particularly the family photos.

You don’t actually say what the failure with your hard drive actually is. Can you provide any more information ? In the above question I mention the Recover Deleted Data web resource – I recommend that you take a look at this site as well, you may be able to find what the problem is with you hard drive and read the advice on getting the data off of it too.

3 Questions about Data

Thursday, September 1st, 2016

Three questions in this post. All about data and it’s loss. The first question concerns a faulty Mac hard drive, the second an overwritten video tape, and finally a question about converting and reading data in an old format.

fixing a hard drive problemQuestion: I have a 1tb WD My Passport for Mac ext hd, last week out of nowhere it stopped showing up on my laptop (I always eject before unplugging). Went to Apple store and they said it might be a b tree failure?! It has lots of photos in it. Can they be recovered?

Answer: The b-tree is the system Mac’s use to store data on storage devices like hard drives. From experience, it’s very unlikely to be a problem with the b-tree, as the hard drive would still show up on your laptop. More likely is a hard drive problem of some kind. Is the hard drive making any different noises at all? You can find a good explanation of hard drive problems, including their symptoms in this hard drive diagnosis walkthru – http://data-recovery-tips.co.uk/hard-drive-diagnosis-walk-thru/.

Question: I have a video tape containing data that was accidentally overwritten. The video was at the beginning of the tape and the duration was around 30 minutes. When I re-wind the tape to the beginning I can see the very start of the overwritten video for a fraction of a second before it cuts to what overwrote it.

Answer: Oh dear, when data is written to video tape it entirely overwrites what was written underneath it. There is no chance of recovering this data. I is gone. I found this useful link explaining how camcorders work here http://www.explainthatstuff.com/camcorders.html.

Question: Do you have the ability to unload and export into either ASCII or EBCDIC, data provided in either AS400 SAV.OBJ or SAV.Lib format contained on a LTO5 tape? if so what is your pricing model and typical lead times and where does the conversion process reside as the data would need to stay within the EU.

Answer: EBCDIC code? Good grief, I haven’t heard that word for about 20 years, when it was an alternative to ASCII, I think ICL mainframes used to use it. LTO5 tapes are a little more recent and I know where to get those converted but I don’t know whether they support AS400 or EBCDIC formats.

More next time! Keep your questions coming!

Help With Data Recovery

Tuesday, August 2nd, 2016

windows error messageThis week I’ve been investigating the world of data recovery. Data recovery is a very interesting subject and something of a “dark art”. The techniques companies use to retrieve information from devices like hard disk drives and mobile phones are shrouded in secrecy because it’s this knowledge that gives these firms their competitive advantages. Here are just of the enquiries received by data recovery service providers in the UK.

> Unable to Boot A Server
Hi I have a customer who has had a server fail on them we are no longer able to boot the server or run a repair i have had the drives out and bought the relevent cables and software to extract the data from a raid 5 but i have had no sucess the drives are 4 x HP 146 gig SAS drives can you help.

> Serious PC Problems
After large thunderstorm, serious problems. PC will start and yellow HD warning light comes on, disc starts to spin up, then dies and it keeps repeating this cycle. HD is Seagate Barracuda ST500DM002 500GB. External backup HD completely dead, power light does not come on. HD is Seagate ST3500418AS 500GB.

> Nexus Tablet Stopped Working
My Nexus Tablet stopped working in June and I’ve tried several people to see if they can repair it and they can’t . What I’m concerned about most is the photos that I’ve lost. Are you able to recover them and if so, at what cost and approximately , how long would that take?

> SSD Hard Drive Problem
I have a problem with my current SSD model : SSD 960go CRUCIAL M500
SSD not booting in BIOS system due to a failure of the electronic circuitry and internal cell of the flash memory
Failure of many cells in the NAND memory due to electric shock. These do not allow access to data in the SSD

> Broken Screens
Broken Screen on iPad 2 Mini and iPhone 5. Not sure if this is something you do or not, but if so, would love to send the business your way to help justify the sponsorship of the great Richie Allen show.

> Two Ticking Hard Drives
I have two drives that are clicking:
1. Seagate ES.1 1TB
2. WD Blue 500GB

> iPhone Water Damage
My iphone, having received water damage, no longer responds – ie won’t turn on or show any sign of life.
Whereas I’m quite happy for the iphone itself to be consigned to the scrapheap, I’d like to recover the data (in particular the photographs) that are stored on it.
Can you be of any assistance?

So if you have a similar problem to any one those listed above, just look on this blog for a data recovery specialist – they are a few recommended.

Possible Electrical Fault on Hard Drive

Tuesday, May 17th, 2016

I received this question earlier today from a reader of this blog:

“Hard drive failure, unable to access data. When in the laptop, nothing would boot, and i believe bios also wouldn’t start. (i don’t know whether that was a laptop issue too or not, the laptops fine now with a new hard drive) The old hard drive will start and doesn’t make any unusual sounds.
If you could kindly advise on potential costs for the data recovery to include the potential need of a clean room.”

Hi thanks for your question. So you have two hard drives? The latest one doesn’t boot but the older one still works fine with no problems?

When using the old one it also inhibits some of the other computer functions such as the BIOS not starting? My guess is your hard drive would be a Seagate and it has some form of electrical problem. I’m saying this from experience, I seen many hard drives over the years that have developed electronic faults which in turn prevent the computer from switching on. The data should be ok and retrievable once the electronic fault on the hard drive is fixed.

Costs for repairing this type of fault are usually no more than £400. The job is also unlikely to require a clean room as there is no need to dismantle the hard drive and remove the lid.

Getting CCTV Images Back

Monday, March 23rd, 2015

CCTV is being used increasingly extensively in the UK these days. It seems like it’s impossible to walk in some places without spotting a ubiquitous CCTV camera high above on a wall looking down. While there is a fair amount of criticism of CCTV recording in public places, CCTV images have helped in the solving of some nasty crimes of late (source: http://www.bbc.co.uk/news/uk-england-london-12080487).

Most CCTV recorders write their images to hard drive where they can be recalled when necessary but what happens if the CCTV images are lost? Who do you go to if you need them restoring?

UK company Data Clinic are CCTV restoration specialists who are able to retrieve the video and images recorded on most CCTV systems. Their skills are known far and wide and are used by the public, business owners and police forces to retrieve potential evidence that may be stored on a CCTV system. They have been asked to recover CCTV images that have been lost and deliberately deleted as well as from hard drives that have stopped working.

Many CCTV systems record the data to their hard drives without issue but some of the hard drives in the recorders are not of the best quality and can break very easily. This is when Data Clinic’s skills come into their own – recovering the images from the CCTV so that they can then be examined by a trained and highly skilled computer forensics examiner who will be able to extract evidence.

 

2014 Round Up

Wednesday, December 17th, 2014

Lots of activity this year in the world of computing and hard drives. Here are some of the lesser known things that went on:

1. The vulnerability of cloud services has been illustrated almost weekly by different hacks and attacks on various networks. The latest, from last weekend, was the hack of the Sony Pictures web site, apparently by a group sympathetic to North Korea over a new American film. (http://www.bbc.co.uk/news/entertainment-arts-30507306)

2. Apple have won an anti trust campaign over it’s music service and iPods. (http://www.theregister.co.uk/2014/12/16/itunes_verdict_in_its_an_apple_win/)

3. Microsoft launch Sway – a new presentation add on to Office (http://www.digitaltrends.com/computing/microsofts-newest-office-product-sway-is-now-open-for-all/)

4. A computer virus used to snoop on organisations worldwide is uncovered (http://en.wikipedia.org/wiki/Regin_%28malware%29)

5. Western Digital and Seagate producing 8GB, 10GB and 12GB hard disk drives (http://www.extremetech.com/computing/186624-seagate-starts-shipping-8tb-hard-drives-with-10tb-and-hamr-on-the-horizon)

 

All Flash Data Centres?

Monday, September 8th, 2014

Will we ever see data centres where spinning hard disk drives (HDDs) have been replaced by flash hard drives (SSDs) ?

Flash memory (SSD)The answer is probably, but according to this news article it won’t be for time yet. The problem is multi faceted, but much of the big issue revolves around the cost of producing SSD flash media when compared against the same process for HDD manufacture. Hard drives of the HDD variety have been around a long time and they are mechanical devices that rotate – this means that to rotate them they have to have a constant power supply which keeps them spinning at exactly the correct speed. For data centres that have many thousands of hard disks this is a big deal as the costs of keeping the HDDs spinning is considerable. Then there is the heat issue too – thousands of rotating HDDs produce a lot of heat that has to dissipated – usually an elaborate air conditioning system is used to effectively transport the generated heat away from the the hard drives. This means more money is spent.

Helium hard drives have been developed that produced less heat and are able to store more and these are getting into data centres but their cost is higher than standard HDDs. SSDs are also made from rare earth materials so there is a finite supply which keeps the price high.
