Data recovery is the science of putting the file system back together so that the data files can be accessed. Every operating system has a file system, which is a unique method of indexing and keeping track of the files. Unfortunately for those that lose data, file systems can be very complex, which is why it can be so difficult to locate missing files. For instance, file systems that are used in business environments require security details and access transaction details. A good example is a transaction-based or journaling file system, whose goal is to log when each file is accessed, modified or saved - making the file system more complicated and harder to rebuild.
Following are some tips on data recovery:
A simple tip could save you a lot of money. Take out your rolodex and get hold of your tech-savvy friends. If you're in luck, they'll offer to help, and if you're really lucky, they might even have some disk recovery software.
If you're out of luck, then get out your wallet or purse out now... because this is going to cost you. Also, be prepared for a lot of time being wasted - data recovery can take a long time.
The first thing to establish is what exactly is wrong with your hard disk:
Either your computer won't boot up, or your computer boots up OK but you can't see one of your other drives.
Let's see if we can eliminate the worst scenario. Listen closely to your hard drive - is it making any sort of weird noise, such as scratching, scraping, ticking etc?
If so, then your drive is physically damaged and the only hope that you have is to take it to a data recovery service where experts might be able to get your data off for you. These services are expensive and time consuming - so you need to make a judgement call as to the value of data on the disk:
- If it's only your saved game data or downloaded music files you would like back, you're probably better off kicking yourself for not backing up, and accepting the data loss.
- If, on the other hand, it's a book or other type of information product that you've been working on for years, then send it to a data recovery service for an evaluation and quote - it usually costs nothing.
- If your hard disk sounds OK, then you stand a decent chance of recovering data yourself.
First you'll need to download some software to help you out.
Unfortunately, the better software utilities are not free, but the good news is that many allow you to try them out to see they can access the data. There are some freeware versions available but generally speaking these are not easy to use - no user interface / little documentation, or they are not very effective.
Hard Drive Data Recovery Software
Higher Ground Software specializes in Hard Drive Data Recovery Software offering the best hard drive repair and hard drive data diagnostic recovery software.
Your next steps will be based on how your hard drives were setup:
- If you only have a single hard drive that has not been partitioned or split into different "logical" drives, you'll probably need to attach the hard drive to another computer that has enough space to store all your data. This can be quite technical so if you don't have the skills please get a computer savvy friend to help out.
- Another option is to purchase an external USB hard drive case. You can then simply slot the hard drive into the case and plug it into another PC using a USB port.
- If you have a multiple drive setup and your computer boots up fine, then it will merely be a case of getting the downloaded software to read the files and then copy them to another drive - provided you have a drive with enough space on it. If not, you'll need to attach the hard drive to another machine with enough spare capacity.
The scenario where you have a multiple drive setup, where the problem drive is the one that contains your operating system files is more tricky.
Look for a data recovery software package that has a boot disk option available. What this means is that when you start your computer with the boot disk in it, it will automatically run the data recovery program without trying to start windows. You should be able to see your files and then copy them across to another drive.
Hopefully these tips will enable you to get all your important files back.
