Hard drive read head replacement

without comments

caution signThe following examples are of faulty hard drives that have stopped working. In all cases, the data is required from them (this is a process known as data recovery). All the hard drive require replacement read and write heads and this is a very difficult thing to do. The best people to retrieve files from hard drive requiring new read write heads are professional data recovery companies like Data Clinic. Data Clinic are UK based and have locations across the country including London, Manchester, Birmingham, Glasgow, Sheffield, Leeds and Liverpool.

I am Looking to replace the read write head of my hard drive barracuda lp 2 tb

The symptoms are its a WD 500GB MyBook, fails to connect to PC you can hear the HDD spinning up making a tinking noise, but then spins down, stops and then tries again.

I dropped my external hard drive from a 2 feet height (approx) and my computer doesn’t detect it anymore. However, when I connect it, the power light switches on and I can hear the disc spinning inside. It doesn’t sound like there are any loose pieces inside and I think the disk needs some replacement read write heads. Is there any chance to recover my data? How long does it usually take?

External hard drive is not recognised whenever i put it into the laptop and constantly making a ticking noise. Has a lot of work on there and wondering if you could help?

Dropped hard drive, ticking noises before powering out. Aproximately 300mb of data but very important work files

Beeping hard drive
Both these hard drives have mechanical type problems and require new or replacement heads:

Need a quote on retrieving data from a 1TB External Seagate harddrive. The harddrive was making a bleeping noise (inconsistent, perhaps every 10s?) The haddrive is not recognized on any computers and does not load any of the files.

The hard drive doesn’t work, makes a beeping sound when plugged in. The light on top of it doesn’t come on and it the computer doesn’t recognise it.

This one isn’t a head problem, and sounds more electronic: Toshiba 1TB hard drive.
Does not look like it has any damage to it. It just stopped switching on.
There is a lot data on there and I would really like to be able to get it back!
Appears occasionally in explorer but crashes when I do eventually find a file.

All that this probably needs is a replacement PCB, it shouldn’t be necessary to open the drive or do anything with the heads.

Caution: Remember – this type of hard drive recovery is best left to the specialists like Data Clinic

Broken Hard Drives Still Contain Recoverable Data !

without comments

When you store important information on a hard disk drive, you take the chance of losing that information because hard disk drives can break for a variety of different reasons. If you’re not computer literate, losing data on a hard drive can be difficult because you don’t know what to do to recover your data. Fortunately, there are companies that can help you get that data back. These are known as data recovery companies and they can retrieve data from nearly any type of hard drive in any type of condition. So when you find yourself in a situation where you have lost valuable information you should not assume that this data can not be retrieved.

Hard drive with cover removed.There are some companies that specialise in repairing damaged hard drives. In the process of retrieving your data, theses data recovery companies can also repair your hard disk. Types of the problems data recovery companies can repair include broken boards, mechanical hard drive faults such as the ‘click of death’ and beeping hard drives. A recommended company in the UK are RAID and Server Data Recovery – you would use a hard drive recovery company when your local IT provider can no longer help you.

Sometimes when there is no damage to the hard disk, software programs can be used to help you retrieve your data by yourself. There are usually trial versions available on the internet that will tell you what they can and can’t recover first. If you decide you want to recover the data they find you’ll have to buy the program which usually costs several pounds. But at least it will get your data back for you. A word of caution though, what may at first appear to be a simple hard drive problem may be something far more serious and trying to recover the data yourself may cause many more problems. So if in doubt, you should always seek professional help as there could be problems inside your disk that prevent it from working properly.

Remember that just because your hard disk breaks or the information on it seems to have disappeared, this doesn’t mean that the data is lost forever. Skilled data retrieval companies that can find and rescue lost data on a damaged hard drive. In the process of restoring the data, the hard drive problems that caused the data to go missing in the first place will be fixed. This is helpful because it insures that it won’t happen again.

Developments in Data Centre Hard Drive TCO

Total Cost of Ownership Graph

The main TCO factors for data centre design

Since social media, data warehousing, online retailing and banking businesses create the most demanding cloud support infrastructures with thousands and thousands of hosts managing petabytes of data, they all understand the significance of crafting an end-to-end storage strategy which appears beyond one time capital cost for the crux of the actual prices – the operating costs related to Total Cost of Ownership (TCO). Cloud architects are creating new guidelines that illustrate the bottom-line value of having a systems wide approach to storage. Usually based on components and software, they deploy drives optimized for special applications that demand efficient power utilization, density and dependability. The important thing: Cloud data centre choices are actually based on value instead of pricing and TCO is how value has been measured.

Embracing the best storage scheme for public, private, and on premise data center infrastructures could make a huge difference in your capacity to significantly lower TCO costs. The key to successfully affecting TCO goes well beyond the price of the drives themselves or measuring effectiveness when it comes to cost per gigabyte only.

Understand the dependability of the hard drives in the data centre. The more dependable the drive, the less time plus price spent keeping it. Drives rated at HGST’s business’s leading standard of 2 million hours Mean-time Between Failure (MTBF) will encounter 40% fewer failures during the five-year life of the drive over these rated at 1.2 million hours.

Raise the density of the present data center footprint with higher-capacity drives. In addition, new up-and-coming helium filled platforms are capable of supporting seven platters per normal 3.5inch HDD, 2 more platters or disks compared to present airfilled five-platter drives.

Power Utilization Efficiency or PUE denotes the proportion of the entire number of power used by a data centre to the power sent or consumed by its own gear. PUE makes it possible to quantify such variables such cooling, electricity distribution and light. The perfect PUE ratio is 1.

Best-in-group data centres like Google and eBay have reported ratios only 1.14 and 1.35, respectively, however an average data centre has a ratio of 2.5. This implies that a typical data centre uses 2-and-a-half times more electricity compared to the amount required to operate the equipment.

If your hard disk crashes, is your data covered by the manufacturer’s warranty ?

without comments

(Author’s Update: Data recovery work under warranty is undertaken in the UK by Data Recovery London (http://www.data-recovery-london.net/)

Data recovery warranty http://www.data-recovery-london.netThis was a question that was recently asked on a TV programme. A man’s hard disk crashed and he had lost all his data. Fortunately he was able to get the broken hard disk replaced because of the warranty, but the cost of the data recovery was not included.

To retrieve the data he had sent his hard drive to a data recovery company to get it recovered. The price tag was about £800. But, he also wanted to have that extra cost covered by the same warranty.

Warranties from any hard disk manufacturers don’t include restoration of data. That said, with the long life time and high durability of today’s hard disks perhaps this is something hard disk manufacturers may offer in the future?

Data recovery companies are usually very good at recovering data from most types of conventional hard disk failure – they are not so good at recovering data from drives that have been involved in fires and floods but these are quite rare situations.

Obviously, it’s always worthwhile to backup all your data or at least backup the data that is most important for you. This is the best warranty against data loss.

If you only use your computer for leisure, playing games or surfing the internet you may not need to take any backup at all. But today, more and more people store important information on their computers – documents and family pictures for example. Others store data vital to their professional lives too – this can represent years of work such as an academic thesis legal papers. Most people store at least some important information such as address books, emails, text documents, family pictures, music or company records.

Should you take backup? If so, what type of backup is best for you?

This all depends on the value of the data should it be lost, the time it will take to recreate lost data, and the cost to make the backup in the first place.

In most cases the data you need to backup is limited to specific files or folders. If that is the case you don’t need to backup the complete hard drive and the cost to make backup is reduced. If you only need to backup documents, emails and address books then there are many cheaper alternatives including USB memory sticks, online backup or backup to CD’s/DVD’s.

If you often use important software from the internet then you need to take a full backup of the hard disk at least once every month. This is because nearly all software programs store system related information in the registry, which if lost may mean you are no longer able to run your software.

As an alternative, make sure that you save the installation files and any accompanied software registration keys in one specific folder after you have downloaded the software. If you do this and include the folder in one of your regular smaller backups, then you will not be too badly effected should your hard drive fail.

Another way to deal with system downtime if you have a hard disk crash is to create and keep a disk image. This is a snapshot of the entire hard disk which can be used to restore your computer on your new hard disk. Included in the disk image software is a boot utility. From it you can create boot diskettes or boot CD’s.
