DROPPING YOUR EXTERNAL HARD!

It goes without saying, but dropping any electronic never gets you good results. This is especially true with external hard drives, also known as portable hard drives, and often leads to the external hard drive failing and requiring data recovery help in order to retrieve the valuable fil
es and data stored on it.

Identify The Problem

Today’s external hard drives are far more resilient to drops and knocks than old external hard drives were in the past, but it certainly does not mean that they are immune. Any drop or knock can cause a head crash in your external hard drive, which means the read/write head of the external hard drive came in contact with the platters.
Electrical surges, water damage, reformatting the external hard drive, and time can also lead to the external hard drive not working. It is important to identify what the root cause of the issue is so you can get an idea of what can be done moving forward to retrieve the files stored on your external hard drive.

Don’t Resort to Software

Because data recovery software only fixes problems that are related to logical issues with the external hard drive, you won’t be able to recover data on the external hard drive from software for physical issues. If your hard drive was dropped, software won’t help, but it also will not help for external hard drives that received water damage, or had an electrical surge. Software really only addresses issues with reformatting, but even then, resorting to software may make matters worse.
You should only run data recovery software on a hard drive if you are certain that it is meant for that type of hard drive. You run the risk of reformatting your hard drive, which will make recovering the data nearly impossible, even for a reputable data recovery professional. There are plenty of free downloadable data recovery software programs on the Internet, and you can do more harm than good when using some of them if you are not careful.

Don’t Try Do It Yourself Methods

It may not be easy, but you should avoid the temptation of tinkering around with the external hard drive after dropping it to see what the real problem is. Nearly every time someone tries an at home data recovery trick in an attempt to retrieve their data, they make it harder for a data recovery professional to recover the data from the hard drive. Methods like freezing, swapping the circuit board, and re-dropping the hard drive (yes people have “claimed” that it works) should not be tested on your own and will likely make it more difficult to recover data from the hard drive.
Never try opening the protective case that encloses your external hard drive! If professionals have to open up an external hard drive, they use cleanrooms to filter out any tiny particles in the air, as they can contaminate and damage the platters and components of an external hard drive.

What You Can Do

Don’t assume that the data cannot be recovered even in the most catastrophic events. Check all sources possible to see if you can locate any backup copies of the files that were stored on your external hard drive. Check media types like any laptops, disk drives, other external hard drives or hard drives that you own, and any cloud backup services you currently use or may have used in the past. Even if the files you locate are outdated or incomplete, they may be your best option moving forward.
If you need to retrieve the files stored on your dropped external hard drive, it is best to leave it up to a trained professional if you are serious about getting your data back. Data Recovery Group is trained at external hard drive recovery, and deals with all sorts of issues, including hard drives that underwent a physical issue like being dropped. Call or email us and we can walk you through your options for getting your valuable data back.

what is RAID 5 Specifications ?

With the migration of RAID, from RAID 0 to RAID 1 and through other variations to RAID 5, Midwest Data Recovery, located in the Chicago area, offers sophisticated RAID 5 data recovery services.

RAID Levels 0+5 (05) and 5+0 (50)

Common Name(s): RAID 0+5 or 05; RAID 5+0 or 50. As with the other multiple RAID levels, verify the exact implementation instead of relying on the label.

Technique(s) Used: Block striping with distributed parity combined with block striping.

Description: RAID 05 and 50 form large arrays by combining the block striping and parity of RAID 5 with the straight block striping of RAID 0RAID 05 is a RAID 5 array comprised of a number of striped RAID 0 arrays; it is less commonly seen than RAID 50, which is a RAID 0 array striped across RAID 5 elements.RAID 50 and 05 improve upon the performance of RAID 5 through the addition of RAID 0, particularly during writes. It also provides better fault tolerance than the single RAID level does, especially if configured as RAID 50.

Most of the characteristics of RAID 05 and 50 are similar to those of RAID 03 and 30RAID 50 and 05 tend to be preferable for transactional environments with smaller files than 03 and 30.

This illustration shows how files of different sizes are distributed between the drives on an eight-disk RAID 5+0 array using a 16 kiB stripe size. As with the RAID 0 illustration, the red file is 4 kiB in size; the blue is 20 kiB; the green is 100 kiB; and the magenta is 500 kiB, with each vertical pixel representing 1 kiB of space.

Each of the large, patterned rectangles represents a four-drive RAID 5 array. The data is evenly striped between these two RAID 5 arrays using RAID 0. Then within each RAID 5 array, the data is stored using striping with parity. So the first small file, and 12 kiB of the second file, were sent to the top RAID 5 array; the remaining 8 kiB of the second file and the first 8 kiB of the 100 kiB file went to the bottom RAID 5 array; then the next 16 kiB of the 100 kiB went to the top array, and so on.

Within each RAID 5 array the data is striped and parity calculated just like a regular RAID 5 array; each array just does this with half the number of blocks it normally would. Contrast this diagram to the ones forRAID 0 and RAID 5.

RAID 5 Controller Requirements:

Generally requires a high-end hardware controller.

RAID 5 Hard Disk Requirements:

Number of drives must be able to be factored into two integers, one of which must be 2 or higher and the other 3 or higher (you can make a RAID 30 array from 6 drives but not 7). Minimum number of drives is six, with the maximum set by the controller.

RAID 5 Array Capacity:

Same as RAID 03 and 30. For RAID 05: (Size of Smallest Drive) * (Number of Drives In Each RAID 0 Set) * (Number of RAID 0 Sets – 1). For RAID 50: (Size of Smallest Drive) * (Number of Drives In Each RAID 5Set – 1) * (Number of RAID 5 Sets).

For example, the capacity of a RAID 05 array made of 15 18 GB drives arranged as three five-drive RAID 0sets would be 18 GB * 5 * (3-1) = 180 GB. The capacity of a RAID 50 array made of 21 18 GB drives arranged as three seven-drive RAID 5 sets would be 18 GB * (7-1) * 3 = 324 GB. The same 21 drives arranged as seven three-drive RAID 5 sets would have a capacity of 18 GB * (3-1) * 7 = 252 GB.

RAID 5 Storage Efficiency:

Same as for RAID 03 and 30. For RAID 05: ( (Number of RAID 0 Sets – 1) / Number of RAID 0 Sets). ForRAID 50: ( (Number of Drives In Each RAID 5 Set – 1) / Number of Drives In Each RAID 5 Set).

Taking the same examples as above, the 15-drive RAID 05 array would have a storage efficiency of (3-1)/3 = 67%. The first RAID 50 array, configured as three seven-drive RAID 5 sets, would have a storage efficiency of (7-1)/7 = 86%, while the other RAID 50 array would have a storage efficiency of (3-1)/3 = 67%.

RAID 5 Fault Tolerance:

Same as for RAID 03 and 30. Good to very good, depending on whether it is RAID 05 or 50, and the number of parity drives relative to the total number. RAID 50 will provide better fault tolerance than RAID 05.

Consider the two different 21-drive RAID 50 arrays mentioned above: the first one (three seven-drive RAID 5sets) has higher capacity and storage efficiency, but can only tolerate three maximum potential drive failures; the one with lower capacity and storage efficiency (seven three-drive RAID 5 sets) can handle as many as seven , if they are in different RAID 5 sets. Of course few applications really require tolerance for seven independent drive failures! And of course, if those 21 drives were in a RAID 05 array instead, failure of a second drive after one had failed and taken down one of the RAID 0 sub-arrays would crash the entire array.

RAID 5 Availability:

Very good to excellent.

RAID 5 Degradation and Rebuilding:

Moderate for RAID 50; worse for RAID 05.

RAID 5 Random Read Performance:

Very good to excellent.

RAID 5 Random Write Performance:

Good.

RAID 5 Sequential Read Performance:

Very good.

RAID 5 Sequential Write Performance:

Good.

RAID 5 Cost:

Relatively high due to requirements for a hardware controller and a large number of drives; storage efficiency is better than RAID 10 however and no worse than any other RAID levels that include redundancy.

RAID 5 Special Considerations:

Complex and expensive to implement.

RAID 5 Recommended Uses:

Applications that require high fault tolerance, capacity and random positioning performance. Not as widely used as many other RAID levels. Sometimes used instead of RAID 5 to increase capacity. Sometimes used for large databases.

What causes a hard drive to click?

A hard drive clicking, also known as the click of death, is typically not a good sign for your hard drive. It means that your hard drive is wobbling on its last legs and will soon no longer be operational. This can be a huge problem, as all information we store on our computers is stored on our hard drives, and being unable to access that information may be a huge issue for everyday computer users and businesses alike. That’s why you should know that this is a serious issue that should be resolved immediately. Before trying anything yourself to get your data back, we’ll explain what causes a hard drive to click, and what you should do to properly get your hard drive back.

What causes a hard drive to click?

When your hard drive is reading data, the render head attached to an arm that moves back and forth in your hard drive scans the platters searching for what you’re looking for. When the render head is unable to find the data that it is looking for, the arm keeps moving back and forth across the platter and hits a stop when it has reached the end of the platter, which is the source of the clicking noise. The render head may not be able to properly read the platter for a number of reasons, and the majority of the problems will be out of your control to fix on your own.

What’s Wrong?

With the majority of cases, the render head is the source of the problem. Over time, the render head will eventually wear out and not be able to read the platters of a hard drive properly. If the render head has trouble finding the data that it is supposed to find, the hard drive will go into shut down mode and it won’t be possible to recover data from the hard drive without the help of a trained professional. There are many other scenarios in which might explain a clicking hard drive and the hard drive eventually crashing, including too much or too little power is given to the hard drive, a chip on the hard drive, or debris on the hard drive platters.

Do Not Remove the Cover!

Removing the cover exposes the platter on the hard drive to airborne debris and will immediately make the hard drive useless forever. Because hard drive platters are so sensitive to airborne particles, it’s very unlikely that even a trained data recovery expert would be able to recover any data from the hard drive. A hard drive cover can only be removed in a Class 100 cleanroom where temperature and humidity is monitored and airborne particles are minimalized.

What Can I Do Now?

It may be too late to say this, but the best way to prevent data loss is to back up your data and back it up regularly. You should keep irreplaceable data in a safe and secure location that is ideally in a different geographic location than your computer in the event of a disaster like a fire or flood. If your hard drive is already making a clicking noise, the best thing to do is nothing. Trying to run data recovery software may lead to additional issues making data recovery more unlikely, and you may not be identifying the actual issue with the hard drive if you try to recover the data using methods that won’t work.
The best thing for you to do is to reach out to a data recovery professional who has seen many situations involving clicking hard drives. Explain your situation, any events that you believe may have caused the issue, and what you have done with your computer or hard drive since it started clicking. At Data Recovery Group, we deal with clicking hard drive issues all the time. Contact us, and we would be happy to help you diagnose the problem with your hard drive.

need your data back recover lost data safely ?

Do you have important files?
Have memories and old photos you do not want to lose?
There is more than one way to keep people important things .. But most of us keep them on the computer and fixed computers and laptop (keep in the Hrddisk inside the laptop or computer).

 

And there are those who keep them in the external Hard disk! .

Many customers when I ask them why you did not back up your files?
The answer is normal .. I did not expect the Hard disks(disrupted)
Does the Hard disks Exposed to fall?! An exhibition for a vacation due to electricity or any other reason!

Yes, Hard disk may stop working without warning and the cost of repair will be high .. Be careful .. Prevention is better than cure.
What if you fell off the Hard disk and become a voice?!

Answer: If your data is important, do not connect the Hard Disk again to your computer .. Do not give this Hard disk to a non-specialist to repair it!.

Make sure that not a computer technician or a programmer can deal with hard disk  .. I assure you that most of the hard disk that can be repaired and of course can not be repaired by anyone is the result of an attempt to repair the initial failed …
