USB Data Recovery Options

USB or Universal Serial Bus Data storage devices are used by virtually everyone these days. USBThey are also known by a variety of names such as a flash drive, pen drive, thumb drive, jump drive, memory sticks etc. They can naturally be plugged into a USB port on a computer and serve as an external hard disk or drive.

They pack lots of benefits and hence their popularity, for a start, their physical size is quite appealing. They are lightweight, easy to carry and can come in a variety of storage capacities; they are thus very portable. There is virtually a flash drive for everyone; both heavy and light users. Another key benefit is the cost. With a good USB costing anything between $10 and $15, they are quite affordable and can pack a lot of data, with some having a capacity of as much as 32 Gigabytes. This makes them a viable option for data backup. Flash disks also allow users to easily gain access to a variety of important applications in a flash such as an antivirus or a web browser as it is easy to install them on any computer that they use. It is also worth noting that some operating systems such as Windows 7 and Windows Vista can also use a flash drive to improve the performance of a computer by using a feature known as Readyboost.

There are several ways or scenarios that may lead to a user losing valuable data stored in their USBs. One of the most common causes is accidental or intentional deletion of a particular file from a USB drive and then being unable to trace it in the trash or recycle bin. Files may also get deleted or destroyed when someone forgets to unplug the flash after the computer has shut down. Malware and virus attacks can also render some files hidden or delete some. In some instances, there may be physical damage to the USB device which may also render the device unusable. Finally, it is also possible to lose data when transferring them from the drive to any other device.

Once you have lost your data in the USB or are unable to access it, you need not worry since that should not be the end of the world. There are several companies that specialize in USB data recovery and have special USB recovery tools which can be deployed so as to help you recover your lost data. When choosing a tool, get one that’s reliable, easy to use, competitively priced and has a fast recovery time turnaround.

SD Data Recovery Solutions

SD CardSecure Digital (SD) is a non volatile memory card that’s widely used in consumer electronic devices, especially portable devices such as digital cameras, mobile phones, tablet computers, GPS navigation devices and a variety of hand held consoles. Its standards are maintained by the Secure Digital Association. The technology has since been implemented in over 400 brands with over 8000 models being availed in the market.

The main causes of SD card failure in the above mentioned devices vary, the most common though include removing the card from a device with the battery still on. It has also been noted that most SD cards get destroyed when placed in extreme cold or heat. The ideal operating range for an SD card is anything between -13 (negative thirteen) degrees Fahrenheit and 185 degrees Fahrenheit. Another major cause of failure is fingerprints or dust particles on the metal contacts; these usually cause fatal read/ write errors.

To minimize instances of SD card failures, there are certain important tips that one should take into consideration. When you notice a card error, the best advice is to immediately stop using the card. This enhances the chances of recovering your data as there will be no overwriting. If you are using an SD card in your camera, avoid deleting the images with the card on your camera, try and do it all at once in your computer, the general rule is that the fewer times you remove or add data on your card the longer it stays. It is also important to know how to safely remove the card safely from the card reader once you are through with the downloads in your computer, in Windows OS make sure you use the “Safely Remove Hardware” and in OSX right click the drive your card has been assigned and hit “eject”. It is also advisable to periodically reformat your card to wipe any file names, data or images. You should always format your card while it is in the device you use it for so as to ensure it is specifically structured for that particular device.

In the unfortunate event that your SD card fails and you lose your data, don’t fret. There are numerous Software and recovery service providers who specialize in the area of SD card data recovery. Most of them are able to recover virtually everything you may have lost in your SD card. When they are performing the recovery, there are several options or modes that are available, these include, the standard mode where the data to be recovered is divided into four main types, namely; music, videos, photos and other files. This allows you to recover either all, one or several of the above mentioned pieces of data. The second option is the advanced mode which provides you with over forty (40) file formats and you are able to recover the exact lost files provided you know the file formats of the data you have lost. It is the best mode as you can get virtually everything you lost.

RAID Data Recovery Solutions

hard-disk-rw-headRAID is an acronym for Redundant Array of Independent Disks. It is a popular way of writing data across a series of disk drives in such a way that if one particular drive fails, the data would not be lost as it is written across several disks. The term redundant is used since the process does entail some duplication of data. The combining of multiple drives into one logical unit is known as striping and it is the fundamental technology behind RAID, it basically partitions the storage space in all the drives into stripes which can be as large as several megabytes or as small as one sector.

The major problem with the RAID system is that there is an assumption that the drives will fail at random times, unfortunately, this is not usually the case as multiple drives have been known to fail in short succession in RAID set ups. The RAID system is normally implemented in what are known as RAID levels, starting from RAID O to RAID 7 then RAID 10. RAID 6 is the best level available while RAID 7 is the most manageable. Generally, the higher the RAID level, the higher the performance and efficiency.

Because the cost of backing up each and every disk in a RAID set up is bound to outweigh any cost savings of using the system from the onset, many people rely on RAID professional data recovery software to recover lost data. There are basically two types of errors that such a solution attempts to rectify, these are Logical and Physical damage or errors.

Logical damage is when a problem such as a power outage disconnects or cut offs a disk midway as it is writing some data. This does imply that the pattern or structure of data stored in the drives does not match the structure of data the computer expects, this ends up causing problems when it comes to reading or even handling the data. This usually calls for the use of RAID data recovery software to analyze the figures and data and find out how the data should be arranged.

The Physical damage usually occurs when the physical surface of the hard drive(s) are damaged one way or the other. For such damages, there are also special software solutions which can collect all the data remaining in the drive then compile the same into a disk image file, this can then be written to a new drive; giving a very close copy of what was lost and damaged. Another method attempts to replace the minimal amount of the disk surface to ensure it is readable; this method normally causes some data loss even though the software strives to minimize such data loss.

When you are seeking RAID data recovery services, it is important to confirm the pricing structure because it usually depends on the level of damage on the disks and the amount of work that will be required to restore the drive.

Hard Disk Data Recovery Options

Hard Drive RcoveryHard disks being mechanical devices are prone to both electronic and mechanical stresses which are all well known causes of hard disk problems. They are thus subject to natural wearing out; as a matter of fact sixty percent (60%) of all hard drive failures occur due to highly predictable mechanical failure whereas forty percent (40%) of the failures can be attributed to misuse.

Since there can be very many causes of hard disk failure, it is prudent to categorize these failures as per their causes. These can be Physical (Mechanical) failure, logical hard disk failure, firmware corruption, electronic failure or accidental deletion. Physical or mechanical failures are usually caused by physical damage to the internal components of the hard disk such as the Logic or Printed Circuit Board (PCB), read/write head, motor, actuator/cam arm or hard disk platters. For such errors always ensure that you get the services of a hard disk data recovery expert so as not to introduce any dust particles into the disk. It has also been noted that hard and rough bumping or jostling of the computer while its running can also cause a mechanical failure.

Logical hard disk failures normally relate to invalid entries in the FAT (File Allocation Table), errors with the file system or severely corrupted data. The user usually hears the disk spinning but is unable to read any good data from the drive. They are usually caused by failed formatting, re-partitioning, incorrect use of an imaging software or Fdisking of the said hard drive or running repair software or disk checking such as Chkdisk, Fsck or Sandisk after a computer has shutdown incorrectly.

Electronic failures are usually caused by a power spike or electric surge and it normally destroys the hard disks controller board. This prevents the hard disk from spinning and makes it impossible for the system to recognize the disk. A sudden power failure when the disk is writing can also cause the disk to crash.

Firmware refers to the software that controls the physical hard drive. If this program gets corrupted and thus unreadable, other parts of the computer will be unable to communicate with the hard drive correctly and it would be deemed to have crashed. Another leading cause of hard drive failure is accidental deletion of important files.

In virtually all instances, your data is not completely lost by virtue of hard drive failure as it can be recovered if proper measures are taken. This can change though and you can lose all data permanently if you don’t use the services of a qualified hard disk data recovery expert or use the correct data recovery software.

For physical errors, identification and subsequent replacement of damaged components in a clean room environment is recommended. For logical errors, the use of data recovery software to repair any corrupted data, repairing of the master boot partition table or record and repairing of the file system is normally recommended. Electronic failures do call for the replacement of the controller board in the correct laboratory conditions. Firmware issues are addressed by having the hard drive reprogrammed while accidental deletions does call for the recovery of the deleted files before the space they previously occupied is overwritten by other files.
