With the advances of computer technology, hard disk failure is still a pulsating reality. And when hard drive failure occurs, hard drive recovery is not far behind. A hard drive is a collection of spinning aluminum discs which spin at 120 times per second. The discs surfaces are quickly spinning magnets. Hard drive is divided into sectors. Each sector, considered as the smallest physical storage on a disc, is 512 bytes in size. For files more than one sector, the file system has to allocate multiple files.
Small interferences to the spinning platter while in usage can damage the disc in one area. When some areas fail, the hard drive is relatively useless. This is where hard disk recovery comes in.
Hard drive recovery may be difficult. Oftentimes, it is an expensive and lengthy process. But recovery is not impossible. Fortunately, there are some procedures one can do before engaging a hard drive retrieval service.
If your computer makes ill-sounding noises then back up data as quickly as possible then purchase and install a new hard disk to facilitate hard drive recovery. More often than not, the cause of hard disk failure is corrupt Master Boot Record 'MBR', whose main function is to tell the computer how big the disk is. Corrupt MBR results in non-booting drive. Windows has easy to use tools that can address this problem. For DOS/3.1/95/98/ME, one can use SCANDISK. NT/XP systems use CHKDSK. Hard disk error may also be apparent in the initial POST or BIOS startup screen. The following factors could cause the problem: check the CMOS battery, reconnect IDE/SATA cables and Power cable, change IDE channel, swap the IDE Cable and check jumpers.
The following solutions to hard disk recovery are also suggested as a last option if you dont want to resort to expensive recovery service. These suggestions may sound a bit outdated but they work just the same.
1. Remove the hard disk cage and tap with the knuckle the outside casing. The shock may free any stuck mechanisms.
2. Place the hard disk upside down in the drive cage. The change in head geometry can occasionally solve the problem.
3. Putting the disk in a waterproof bag then put in the freezer overnight and back to the pc. This method might work and allow you to quickly transfer the data before it dies again. The theory behind is that the freezing could expand/contract metal components thereby freeing mechanisms.
If the data you lost is very important and cannot be retrieved using the above-mentioned methods then it is best to use hard drive recovery software or a recovery service before the problem gets any worse.
Corrupted Hard Drive Recovery
Hard drive recovery can help you reclaim lost data that would otherwise be impossible to restore. While hard drive recovery sounds promising, you still have the task of choosing the correct solution for your particular problem, and then following through with the appropriate steps to get your data recovered.
Finding Your Solution
There are two basic directions you can go when it comes to hard drive recovery: Using a professional recovery center, or a do-it-yourself utility. Software are much more economical to use than a service company, but they are less reliable than using a professional for obvious reasons. My part is to help you determine which one suites you best.
Software verses Service
What I have found out over the years is that almost everyone wants to try hard drive data recovery software, because it is cheaper, quicker, and private. That being said, some users have no business using hard drive recovery software, because they make matters worse by not understanding the fundamental setup and recovery steps.
The cry from technicians to make more sophisticated hard drive recovery tools has also caused an increase in the number of hard drive casualties. This is because the more powerful the solution, the more damage that can occur. Yes, these powerful programs can recover more data, but if you do not know the proper procedures, they can also destroy data.
Research and Development
I have had many conversations over the years with colleagues from various hard drive recovery centers about what level of software they want us to develop, and how much of the program should be offered to the public. There have been two reasons I have researched this topic:
First, is for economical reasons. Obviously, the cheaper the software, the more people will use these hard drive recovery tools. On the other hand, the more powerful the utility, the less need the public has for sending their drive to a hard drive recovery service. Because we also develop tools for these firms, we have to balance pleasing both groups of users, which at times can be a challenging task.
The next reason for this research is for data safety. In other words, how much do we need to protect you from yourself? We truly want you to recover your own data, and helping you prevent undoable mistakes is part of the process. I say this because invariably I (and other service companies) get drives weekly that have been trashed by misusing software utilities. As a consequence, many of these drives are considered unrecoverable.
Defining the fine line between offering you cutting edge technologies in the form of software, and making you send your drive to an expert to protect your data from your possible fatal mistakes, is a difficult decision. I say this because I know you want to try the recovery yourself - at least as the first step.
Your Next Step
While you do not want to delay in getting your data back, you also want to take the right steps to protect your data. I want you to be asking yourself, "Can I do this myself, or should I use a hard drive recovery professional?" If you are not sure, get help. You know your capabilities, and by reading this information, you will probably know which solution is best for you.
