What is a Jump Drive? Jump drive is nothing but just another new terminology given to those small devices which we use daily for storing or transferring files and data. Some other popular ways to address a jump drive is by using terms like the pen drive, USB flash drive, USB stick, zip drive, data stick, key chain drive or the thumb drive. It is usually the size of a human thumb or sometimes even tinier. It is connected to a personal computer with the help of a USB port. It is the simplest way to store or transfer data or files from one platform to another.
It supports storage of many size values like 256 MB, 512 MB, 1GB, 4 GBs and many more. Often we experience loss of data in these jump drives. There can be many reasons for such data loss. Due to corruption of the software used to run the jump drive, poor handling, negligence while ejecting these drives from the computer, electrical short circuit etc. In these scenarios important files gets deleted and it can pose problems to an individual. Jump drive data recovery is difficult but, no one said that it is not possible. Let us read on some ways how we can recover lost data from jump drives with the help of some applications.
Here are some ways to prove that jump drive data recovery is possible:
- PhotoRec – This is so far the most popular and powerful recovery application. From almost any type of device this application can recover lost data. For all platforms like Windows, Linux or the Mac operating system this software can be used. The developer of the PhotoRec app states that the software is capable enough to recover more than 350 categories of data types. All the storage devices attached to a system is detected by this application and it efficiently recovers data.
- Recover My Files – This data recovery application comes for Windows 98 operating system and for later versions. The software comes in a trial version and also has different paid iterated versions to recover different kind of data requirements. FAT or NTFS partitions, HFS and RAID support is also provided by some versions. The software gives user two options. One is whether one needs to recover one file at a time or files from the entire drive.
- Recuva – Recuva is an autonomous system which begins recovering files when started. It is a small sized program and the free version also has the majority of the features in it. Jump drive data recovery can very easily be done with the help of this software program. After beginning this program it first makes few queries to the user about what kind of recovery is expected from it. Once properly filled up it is the job of Recuva to help you recover all your precious files.
- Remo Recover – Another quite handy little software program that runs of Windows 98 and also for later versions. As per the requirement of recovery the software has different versions of it.
What is a RAID controller failure? The technical abbreviation for RAID is Redundant Array of Independent Disks. It is also termed popularly as inexpensive disks. Small independent disks when combined together for the formation of a disk with a big space are actually what are meant by RAID. These disks are added into different arrays and these are called array members. There can be many reasons for a RAID controller failure. An efficient technician can easily diagnose by observing the blinking of the lights present in the array chambers to understand whether there is a controller failure or not. A failure will fade out or change the color of these lights or completely deactivate it.
Perform these initial steps when you come across a RAID controller failure –
- At first one must make sure that the drives are proper electronically. One can use an Adaptec SSCI controller for the SCSI drives. These are not at all costly and are used for a long time and hence are free of any kind of firmware bugs and errors. In case of such RAID controller failure it is recommended to add the SCSI card into a computer which is stable and mount every drive separately. If these drives are either SATA or PATA then one can use a basic port.
- The “device manager” can help you in such a scenario. It can be used to detect the name of the driver. If it does then it signifies that the interface of the drive is safe and there are some chances to do input and output activities in between the driver and the computer. The DTI makes use of its free scanning technique to scan and check each and every drive and detect if there is any harmful sector.
- Suppose, your scan shows that two or more sectors have turn corrupted then it might be the very reason why the RAID controller failed. These RAID controllers are vulnerable in nature and get easily affected if there are bad areas.
- Another step which is crucial on the occurrence of a RAID controller failure is to undergo a set of mathematical calculations on the stored data. This is done by the RAID 5 controller itself for reverse engineering the entire data to try so that the drive drops out of the array by any means. The maths calculations XOR are made for rebuilding up the array by using a degraded quality 5 hard drive. A RAID controller 5 is capable of rebuilding a drive newly into the array.
- As a matter of fact, free diagnostic tools are available like the DTI Data which can scan the entire array and find out whether there is any bad area in the drive. The software is capable to find out this damaged drive and by building up a virtual raid controller 5 it can easily recover data and images which are lost. This DTI Data has several tools for diagnosing such failures and solving them.
This piece of writing is about SAN and the entire in and outs of a SAN data recovery. SAN, also termed as storage area network is a framework or an architecture for attaching together isolated computer storage disks and device arrays, various libraries of tape and servers and jukeboxes. It makes a system in such a way that the operating system seems to appear as if they are attached locally. By sharing spaces of storage it makes organizing data in a simple manner. It also makes the entire process flexible because the cables and the devices for storage are not required to be moved physically. Similar to any electronic device, a storage area network might also fail unexpectedly thus causing a lot of troubles.
Using the SAN technique an individual can extend a network almost endlessly. One can attach and connect different storage devices like a RAID array. Due to its reliability and stable nature it is used hugely by entrepreneurs, businessmen and corporate houses. SAN Data Recovery depends directly one how many storage networks are attached or detached with one another. Because depending on these chances of a data loss occurrence is either high or low.
What steps to be taken?
In situations when your computer hardware or the SAN fails and there is huge data loss here are the few steps an individual must take. SAN Data Recovery can also be done by taking assistance from the Houston data recovery experts. There are no where a guarantee that data loss will never happen.
- The first and foremost recommendation is never panic. Panic can make you take wrong steps which can further delay the recovery process.
- At first make sure to disconnect the electrical connection of the computer hardware.
- Also, do not start opening up and hardware with an intention to repair all by yourself especially if you do not know the trade. It is always advisable to take some professional help.
- It is suggested for contacting a person who is an expert in this field and not an amateur.
What are the causes of a SAN data recovery?
- A damage of failure of the computer mechanism.
- Due to a failure of hard drive which is multiple.
- If two hard drives attached together fails or gets damaged simultaneously.
- Failure of electrical circuits switches or network bridge etc.
- A storage network damage or complete failure.
- Due to problems in the interface or the operating system many times the SAN can fail.
- Due to failure of the interface of the storage area network.
- A hack or intervention or an outside unauthorized effort to access data.
The only thing which is not at all recommended is to do trials to fix it all by you. If a person has adequate knowledge about the network and the various ways to recover data loss in a SAN then it is a great thing. Or else such trial and error can further augment the problem rather than solving it.
At least once in our lives we have faced this issue of hard drive getting damaged or failed. Even after repeated rebooting of the machine it fails to start up. It is very important for every one using a computer to take regular backup of their works. A hard drive crash can cost an entire life’s data and files stored in the computer. However, there are ways to recover data from a damaged hard drive. It is also important to be able to diagnose whether your hard drive is about to fail or has already failed.
Diagnose an external hard drive
In case of an external hard disc failure; many times due to the enclosure of the wired connection it might seem that the hard disc has failed. For surety you need to check it. Be sure to protect yourself as the body of the hard drive can generate static electricity. Firstly, it is important to remove the drive and with the help of a SATA or IDE data cable install the external hard disk inside the computer. If the connector was the problem then now, after installing it the Windows will be detecting it; and it will signify that there is no data loss.
Diagnose an internal hard drive
Sometimes it happens so that the hard drive is in proper condition but the cables connecting the drive with the motherboard of the machine has some problems. Hence, one can check whether all the cables and wires are connected properly. It is advisable to power off all electrical connection and then strongly plug-in the cables. By checking that all cables are plugged properly restart the machine to check whether it is working or not. If the cause is a damaged hard drive then the machine will not be still working.
Well, there are many more indications to diagnose damage many times misunderstood to be a hard drive crash. Some of them have been mentioned below:
- Sound – When a computer runs the sound of the hard drive can be heard. Observer whether it is sound right or not. A sharp shrill sound or repeated beeps can indicate a potential damage. It is very important to understand these subtle indications given by the system.
- Hard drive recognisability –
Many times, the hard drive although makes a sound it does not open the drive. In such cases it is required to manually check from BIOS. When the computer is started you can press either the DEL button from the keyboard or ESC or F2 or F10. These keys will open up the BIOS. It is a place from where one can navigate in diff parts of the machine. Using various DOS commands one can check from here whether the drive is connected with the machine.
- Whether the circuit broad is broken apart?
External as well as internal reasons can cause a damaged hard drive scenario. A PCB damaged can cause a crash. However replacing a PCB can create problems in the machine.
Evolution of desktop hard drives: The Evolution of hard drives over the last few decades and years is worth mentioning. If observed backwards then the journey is well covered and look where we stand now. Desktop hard drives have gone through many stages of development. Starting from the enormous huge sized rooms acting as storage spaces to the tiniest devices in our palms the evolution has been amazing. Let’s go back to the years and see how hard drives has evolved and become better with passing years.
Year wise breakup of the changes of hard drives briefed below –
- The 1950s – It is during the 1950s the first hard drive was shipped by IBM which was used in a RAMAC 305 system. This hard disc had a space to hold 5MB of files or data and costed $10,000 for one megabyte. The size of this system was that of the total size of two refrigerators.
- The 1960s – During the 1960s, IBM came up with a hard disc which is removable in nature. Also termed as the 1311, this hard disc held 2.6 MB data. It is IBM who first invented the concept of heads in a hard drive which can fly on a bearing in air. The first drive with the head made from wooden coils ferrite was introduced during this time.
- The 1970s – In the year 1971, the General Digital Corporation got renamed and was called to be Western Digital and was located in California. Here, desktop hard drives saw its first international acclamation. IBM founded the “Winchester”, the 3340. It was during this time the patent for RAID or Redundant Arrays of Independent Disks was filed. Seagate, the world famous disk and drive manufacturer was founded during this time. Seagate introduces in the market the ST 506 hard drive which became popular and was being used in all applications of microcomputer.
- The 1980s – The first hard drive which was a gigabyte size was introduced by IBM during the 1980s. It weighed approximately 550 pounds and the cost was $40000. During this time Seagate made its release of a new hard drive which was 5.25inches in size. Western Digital during the 1980s created the Winchester with a hard drive controller, a card for the PC/At for IBM. Apples Mac Plus begins to make use of the SCSI first time officially.
- The 1990s – Some of the worth mentioning introductions on the 1990s were the 3.5 inch Caviar IDE by Winchester, the 0663 Corsair by IBM, the 2.5 shock sensor based hard drive by Seagate and many more.
2000 and present – The 15000 rpm the first of its kind hard drive was released by Seagate. The 2000 millennium saw all the latest innovative experimentations in the field of computers. Be it magnetic heat resistant recording technologies or the amazing 40 GB hard drive by Toshiba on a 1.8inch base. Transformation and improvements are still going on at a rapid place and the sky is only the limit for these creative inventions.
