I was just wondering what some good tools used to recover files and nolder such are used in computer forensics? I have an older hard drive that I have wiped and would like to practice recovering data using these tools and techniques.
After bringing the failed drive back to life, as a data recovery professional, you know now you need to recover the damaged file system by using data recovery tools; and maybe you know also you need to do a disk imaging in order to work from an accurate, stable hard drive image.
Unfortunately, traditional disk imaging tools and methods are designed for and work on good HDDs only, not the patient HDDs that are unstable or inaccessible because of media defects and instable head, which are common challenges of Stage 2 in practice. Even more, with those traditional imaging tools, the time involved and the ordinary user-level repeated-read access to the media bring a risk of damaging the disk and head, making data lost irretrievable.
But now there’s a better way: The disk probing equipment included in the Data Compass suite bypassing the disk-level problems such as multiple bad sectors, damaged surfaces, malfunctioning head assembly, or corrupted servo info, In the meantime you can use the default software or any other defined software you have been familiar with (R-studio, Winhex, any) to perform file recovery. Through the Data Compass, problem drives will become intact hard drives and ready for file recovery attempts..
What can Data Compass do?
Data recovery from physically damaged HDDs is what Data Compass designed for.
* Data recovery from HDDs with severe multiple BAD sectors, which appear because of platter surface scratch or malfunction or instability of the magnetic head assembly (MHA).
* Data recovery from HDDs that start to produce “clicking” sounds, which may be caused by corruption of sector servo labels or a MHA malfunction. If some heads or surfaces are damaged it is possible (before installation of MHA replacement) to create a copy of data using the remaining good surfaces or drive heads.
* Availability of tools for logical analysis of FAT and NTFS file systems in the software complex allows data recovery in cases, when a drive is functional and only logical data structure is corrupted.
* When used with malfunctioning drives, Data Compass complex often allows selective extraction of data necessary to your customers without reading all data from a drive (“recover data by file” without creating a complete disk image) saving a lot of time. In some cases, when drive malfunctions cause constant self-damage (like scratches on disks or instable MHA) these are the only means to accomplish this task. With the ShadowDisk technology adopted, users need not to worry about the drive degradation problem.
Customer Reviews Of Data Compass:
“The SalvationDATA Data Compass easily helps me get rid of SA bad sectors which can’t be repaired by other drive restoration products we’ve been using before, because it gives access to user data area directly by using its Analog technology which virtually boot the hard drive SA-independently.”
- Yimei Cao, Lead Data Recovery Engineer CBL Data Recovery Technologies Inc. www.cbltech.com
“Data Compass helps us to restore data from hard drives suffer from sever bad sectors, which are not able to be recovered from other tools in the DR market. Especially, by using the advanced Service Area (SA) emulation technology, it accesses the data from firmware defective hard drives directly. Also, multiple settings of the reading algorithm enables the optimization of data recovery from hard drives with poor performance of Head & Disk Assembly (HDA)”
- Zijian Xie, Research and Development Manager Computer Science Labs, UK. www.computersciencelabs.com
Data Compass with Data Compass Explorer is now the premier choice amongst the Data Recovery Industry for fast and effective extraction of data from hard drive’s with severe unreadable sectors, media degradation and failing read/write heads. It is now officially my favourite tool in my vast collection of data recovery solutions and it is only going to get better over time once the new functions are completed. I especially look forward to the head selection function and the future Seagate, Western Digital firmware bypassing options. I’m so impressed I am considering ordering several more in the near future.
Michael Owen, Managing Director Datatrack Labs Ltd. www.datatrack-labs.co.uk
“I’ve started playing with settings of Data Compass and found it quite easy to use. I’ve already carried out a couple of data rescue tests with success and I’m quite satisfied about the performance of the tool.”
- Filippo Corsi Computer Discount Siena www.computerdiscount.it
“I received my Salvation Data Compass last week and I would like to share my experience with you.When I saw the release of Salvation Data Recovery Data Compass I was a bit skeptical about the ROI of this product. Since I’ve been in Data recovery for over 4 years and I manage to do most of my job with my current equipment (PC3K ISA, HDD Duplicator etc…) After reading spec and cases study about this product I decide to go ahead and try it.”

Data recovery is used when serious situations and accidents occur to your system, like when hard drives has been formatted, or if you accidentally delete a file that you really need, which is no impossible, or it can also be used when a virus enters your system and deletes some of your files and information. The great thing is that any data recovery software works sufficiently with most computers and operating systems.
You can use data recovery software to recover information from your local hard drive, your extra hard drive, a floppy disk, a removable or portable hard drive, memory cards, and in most cases you could even use it to recover information from old CD’s. In addition a hard drive crash is no match for data recovery software. The other great thing is that you will be able to recover basically every piece of information that was on you hard drive like your email messages, video files, music and photos and obviously your data files and documents.
There are two main ways of retrieving lost data using a data recovery software, one being when the file you are retrieving has been recently deleted, the other option is to recover everything that has been on the hard disk and from there you find what you are looking for.
There are many different data recovery software programs you can use to recover your files; some of them even let you browse through your deleted files to see what you would like to retrieve. There are processes that can recover and restore your deleted files in seconds! Once the data has been recovered from you hard drive you have the option to either save it to another folder on a different hard drive or storage device, or you can burn it directly to CD. Once your files have been successfully recovered by the data recovery software, all your information stays the same, which is to say that nothing will have been changed, even in the event of a virus overload, the file names and all the date will still be in tact.
Your lost files can be restored in one click and they can be stored by name, size or date of saving. A search session also gets saved to a disk file that is used later for reloading so that the drive will not need to be scanned again, which makes the restoration process so much easier and quicker.
Majority of the data recovery software programs are offered as free demo version. You can easily download the software from the internet and try how it works.
when it is a mechanical failure and they need to remove the disk inside the drive. And is there a special machine they use to hook up that hard drive disk to?
The Linux community are fast realising that losing data is factor that happens no matter how careful you are. And it can happen easily when your upgrading you distro every 6 months. Here are the top 5 opensource linux tools out there to help the Linux community recovery the data they forgot about on t he previous distro.
1. TestDisk-PhotoRec The most developed data recovery program on Linux, designed to recover lost partition and to make non-booting disks bootable again. Very useful when you accidentally delete when installing the latest distro. Testdisk is now joint with PhotoRec which recovers files from severely damaged or re-formatted media.
2. ntfsundelete Part of the ntfsprogs; ntfsdelete scans for files located on the delete inodes and lets you extract the files. Even though it is for a Windows system useful for those countless of people that have used knoppix to repair their failed Windows system. Now with an added tool.
3. e2retrieve A useful tool to help repair and recover data from a ext2 filesystem. can recover data from a truncated or split ext2 filesystem (in the case of a LVM with a disk that has crashed, for example) will not write onto the ext2 filesystem it is analysing, therefore it will never increase damages previously caused recovers directories, directories tree, files, symbolic links and special files with their access rights, owner and modification date
4. Magic Rescue A program that recovers data by looking at the headers and footers of files but using the “Magic Code”. Basically a program that you can specify the headers and footers to scan for RAW data.
5. e2undel e2undel is an interactive console tool that recovers the data of deleted files on an ext2 file system under Linux. Included is a library that allows to recover deleted files by name.
Conclusion
The Linux data recovery tools have a long way to go if they are to compete with some of the commercial software and even freeware on Windows. However, as we all know Linux started from humble beginings. If they could put all these tools together and add a GUI we would be looking at something very useful indeed. There are many good shareware and freeware programs out there that can help you recover your files.We recommend you test and learn first before you attempt any recovery yourself. As always most important point – Don’t save on to the disk you want to recover from!!! If your data is important leave it to the professionals.

The latest innovations in the computer field may prompt people to sell their old computers to buy new and the latest model computers. When selling the old computers, one normally deletes all the files on the computer, re-install the operating system and sometimes also format their drive so that all the files and data found in the computer does not fall in the wrong hands.
However seldom are they aware of the fact that their personal and private information may still remain on the disk in an unallocated space. It is only with the help of a data shredder software is it possible to get rid of all pictures, data and information permanently from the computer.
It is very important to get rid of all sorts of data fragments that may be present in the computer with the use of data shredder software. This is because if you venture to sell or discard your old computer without getting rid of all the data in the computer may only lead to irreparable, financial, political and personal damage to the owner or organization of the computer. There is a chance of this personal and confidential information falling into the hands of terrorists, pedophiles and also a possibility of the owner of the computer getting blackmailed or threatened, if it reaches the hands of hackers.
The best thing to do to get rid of all types of information permanently is with the help of some data shredder software. This software can be bought for a fee on the internet and can also be accessed from the internet for free. All you have to do is to visit the data shredder software site and pay for the software wherein you will be able to download the software to your computer. With this software installed, you are sure that all the information that you want to be eliminated from the computer is genuinely deleted.
Most of the data shredder software not only helps in shredding data from the computer, but also helps in data recovery. This is an important part of the data shredder software as many a time a file that was not supposed to have been deleted may get deleted. In such cases, there will be a need of recovering the file that was accidentally or intentionally deleted. So it can be seen that it is very important for all computer owners to have some type of data shredder software installed in the computer at all times.
The hard drive of your computer stores a lot of data and files. If your computer crashes it is a crisis as most users depend on their computer for data and information.
The loss of data can be as a result of corrupt hard drives, viruses and Trojans. There are many reasons why a hard drive can crash like power surges or data can also be accidentally deleted.
However all is not lost as you can get hard drive data recovery tools which can enable you to retrieve any lost files.
This software helps recover data from hard drives saving yourself unnecessary stress. These hard drive data recovery tools are available online or in stores and are easy to use. You can check out websites offering free online down loadable trial versions. Most individuals using computers are not technically inclined and the need to have a good hard drive data recovery software is important.
But a word of caution when trying to use these tools yourself on your computer, be careful because sometimes trying these methods can further damage your hard drive to a point of no return in terms of getting your data back.
If the hard drive data recovery tools don’t work then you’d need the services of a professional hard drive data recovery expert to recover the deleted files from your hard disks. They don’t come cheap as this is not a job for your local computer shop. Their services are expensive and their charges fairly steep as most of these specialists know their customers value their data more than even the computer itself.
One of the things that you can do to avoid this kind of situation to make sure you are never at risk of loosing your data again are :
Backup your data with an extra hard drive, CDs or DVDs or use online remote recovery data facility
There are some well known names like Carbonite and Mozy who do unlimited online backup.
If you want to save yourself the stress from data loss you can check out online the many things you can do to make sure you are never at risk of losing your data and invest in reliable hard drive data recovery tools.
