A Complete Data Recovery Solution:
No matter what kind of computer you use data recovery is a main concern for everyone. Laptop data recovery, PC data recovery, notebook data recovery all fall in under one roof when it come to data recovery. So what can you do about it?

Data Recovery Situations

Most data recovery situations are common to most users like file deletion or damages, virus attacks, lost files due to emptying recycle bin… So the best solution for these kinds of situations is the use of data recovery software.

Hard Disk Drive Maintenance

Mon, 21 Apr 2008 15:19:32 +0200

You want your computer to last. cleaned out the mouse, kept out the dust... but that's all about 'hardware' . We should be confident in keeping the software in good running order.

We are lucky for, Microsoft provides a couple of tools to help keep our hard drive and the programs on it healthy and happy (and running longer) as well. The best part is (if we have Windows), they're already loaded on our machine! We will be going through few of them.

The first thing we need to do is locate them on your hard drive. Right-click the Start button and select Open, then double-click Programs, then Accessories. You should see a folder called System Tools. Double-click System Tools to discover a bunch of stuff we never them.

The first one we're going to look at is the Disk Defragmenter. What's a defragmenter? programs save files to the hard drive, they try to grab the next available space (this is simplified, of course) to where we save the last time. If the space is 'right next door', it's called 'contiguous' space. That's good space, because when the program is reading the hard drive, it just goes 1...2...3..., everything is in order.

However, if the space next door is taken, it will have to search around and put your files somewhere else. After a while,it is trying to read it back in as 1...78...32...that can take longer and can result in Windows losing track of where the parts of a file are.

In order to put everything back in order, you must defragment the disk, which takes all the pieces of all the files and puts them in contiguous space. I defrag , but some recommend it be done at least weekly.

To run the Defragmenter, double-click the icon, select the drive you want (your hard drive is usually 'C') and click OK.Then go make a sandwich, as this will take some time. Windows will read all the programs on your hard drive and put them together with all other parts of that program, freeing up space and making your machine run better.

We've freed up some space now, but we want more. Where can we get it? One place is by deleting all the temporary files that Windows has kept for you. Double-click the Disk Cleanup icon, select your hard drive again, and a popup box will appear showing things like Temporary Files, Recycle Bin, all the places that Windows knows of files that are not needed. Select the ones you want and click OK. They're gone, and you have a lot more space for those new downloads you want.

If we are constantly low on hard drive space, it might be best to do this before you defragment the disk, then you can free up all that used space as one big block.

The final program is called ScanDisk...it's the one that comes on when you boot up after failing to shut down the computer correctly (if you should have a lock-up or lose power, for example). Double-click the ScanDisk icon and a box will pop up and give you a number of choices. Select your hard drive, and then either Standard or Throrough.

A Standard scan will check your files and folders to make sure everything is 'pointed' in the right place. It doesn't take long to do. However, before you run it, it's a good idea to close every program you can, because if these programs write to the hard drive while Scandisk is running, ScanDisk may have to start over...it can be pretty frustrating if that happens.

If you've closed everything and it still keeps restarting, it might be an indication that a program is hung up... shut down the machine, restart, and try it again.

A Throrough scan performs a Standard scan, but then checks the hard drive itself for errors (like a 'spot' that won't record data correctly), and marks them 'off limits' to the computer so data does not get lost there. All hard drives develop 'bad spots', so it's a good idea to run a throrough scan at least monthly to catch them.

If we really want to play around, there's also a 'Task Scheduler' which will allow you to automate this process,this process is some what typical, but some people find that it easier to perform preventive maintenance if they set reminders for themselves.

definitions & recovery

Mon, 21 Apr 2008 15:16:13 +0200

Defintion:
Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible primary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drive, storage tapes, CDs, DVDs, RAID, and other electronics. This can be due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system. Although there is some confusion as to the term, data recovery can also be the process of retrieving and securing deleted information from a storage media for forensic purposes or spying.

Recovering data after physical damage:
A wide variety of failures can cause physical damage to storage media. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of several mechanical failures, such as head crashes and failed motors; tapes can simply break. Physical damage always causes at least some data loss, and in many cases the logical structures of the file system are damaged as well. This causes logical damage that must be dealt with before any files can be salvaged from the failed media.
Most physical damage cannot be repaired by end users. For example, opening a hard disk in a normal environment can allow dust to settle on the surface, causing further damage to the platters and complicating the recovery process. Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs; therefore, costly data recovery companies are consulted to salvage the data. These firms often use Class 100 cleanroom facilities to protect the media while repairs are being made.
Despite this, there are many accounts of users getting a bad disk going long enough to pull their data off, often via slightly bizarre tricks. These include making the drive cold (in the freezer) or spinning it manually on the ground, both actions being used to unstick a jammed platter. Most data recovery professionals recommend against the use of tricks such as these, as they can cause additional physical damage to the drive if done improperly (and in many cases, even when done properly).
