Does anyone recall the olden days when there were no PCs around and you did all your saving in actual touchable folders and files? And remember how you had to archive them for years and years to come? So 10 years later you'd send your secretary (or you were the secretary sent) to the archive and tell her to discard year 1961 to 1970? And what did she do? Throw'em away? Sure she didn't - you could use the folders again, if emptied. Now, did she empty them right away? No, she didn't. She just ran along the shelf and tore off the labels so that everybody knew those were the folders to be used again next. When you opened one of those folders all it's content was still in perfect shape, readable and all, and if you'd made a mistake and you'd need one of those folders i.e. it's content, you just had to be quick enough... That's the way MS Windows handles your data. They're written to your hard disk, kept there according to your wishes and once you decide to get rid of them, all the space your data occupy on the hard disk is marked for reuse, just like tearing off the labels of those nostalgic folders. File recovery relies on the fact that when a user deletes a file (or empties the wastebasket or recycle bin) the contents of the file aren't physically obliterated on the disk, but rather the file is simply flagged as deleted. More precisely, the space it occupies is marked as available for writing. This means that the older the file, the less chance there is of successful recovery because it’s more likely to have been overwritten by another newer file. File recovery software works best when the deleted files are recovered to another drive. That's because the very act of recovery involves writing to your drive, and you don't want to write over other files that still need to be recovered. The "other" drive can be another hard disk, another hard disk partition, a networked machine, or an external USB device. Recovery programs operate more successfully if they are installed before any file recovery is attempted. If the file you want to recover is on your “C” drive, the simple act of installing one of these programs onto that drive may obliterate the target file you want to recover. Remember that recovery software cannot undelete files that have been written over. Recovering data from physically damaged drives is also beyond the capabilities of most free recovery tools. There are tools that will attempt partial recovery, but generally these are expensive commercial products or services. However, if you have just accidentally emptied your wastebasket (recycle bin), or explicitly deleted a file, and realized you've made a mistake, file recovery is a very real possibility. The golden rule is “don’t write ANYTHING to the disk, or reboot”. Just immediately run your recovery software. |

Until recently, file recovery was one of the few categories where the main commercial products really outshone the freeware alternatives. Good examples of commercial products include the impressive "R-Studio”, “Recover My Files”, and “Active File Recovery.” But the picture has changed dramatically. You now have now some excellent freeware choices.
PC INSPECTOR File Recovery is a truly outstanding professional product. I suggest you install it just in case you need it (and while it remains free).
Free Undelete does what you expect it to do and indulges with a rare highlight: in its 'toolbox' you find a wide variety of standard formats to be easily rescued. Another tool of acceptable basic features is Undelete Plus. But I deny them my full recommendation because Free Undelete froze repeatedly on an USB-stick, and Undelete Plus has minimal functions. |

I'm wondering if anyone has had experience with Pandora Recovery 2.x in comparison to the utilities listed here.
My computer has been acting buggy for the past couple of months, and on launching it this morning I found that an important folder of mine on an external hard drive.
I'm currently using Pandora Recovery to locate the file. The folder was not located using the Search or the Browse utilities, although it found some of them as Unknown folders. I'm currently running an Optical Scan to locate everything that has been on the disk - it is slow, but seems to be working relatively well.
Any thoughts?
Say people,
Anyone got PCI Recovery to work in Windows 7?
Mine does not seem to to be able to find the logical drives.
Thanks
TC
TC, you have to run it as administrator. Right-click the program icon on the Start Menu folder and select "Run as Adinistrator".
BTW, PC Inspector just saved me 1.0 Gb of pdf articles and ebooks and, through that, 99% of my research. Thanks, Gizmo!
5 free photo recovery softwares mentioned here :
http://www.online-tech-tips.com/free-software-downloads/free-photo-recov...
i find testdisk and photorec able to recover files in my damaged windows partition. both programs come pre-installed in the knoppix live cd, which i converted to a bootable USB (courtesy of the guys at www.pendrivelinux.com)
I'll take a look at the recommendations below and evaluate to see if we need to adjust the category recommendations. Keep the suggestions/comments coming!
I have good luck with Avira Unerase.
http://www.free-av.com/en/tools/10/avira_unerase_personal.html
This note is there on the same page below the product :
NOTE: The Avira recovery products "Avira UnErase Personal" and "Avira NTFS4DOS" have been discontinued and are no longer supported by Avira. You may download them for personal use only and Avira accepts no liability.
So use at your own risk, and with caution.
I figure Recuva is the best utility freeware to recover accidentally lost files around.Thanks for sharing

I also find the free data recovery wizard at here: http://www.techsupportalert.com/content/easeus-data-recovery-wizard-48-f...
Great!!!
Thanks
More free options listed here too: http://www.thefreecountry.com/utilities/datarecovery.shtml
First off, thanks for this section and to all the helpful posts. What follows is my experience after loosing over 600 scans of 3mm negatives on an SD card. Yes, shoulda backed up as I went along.
Undelete Plus, free: will scan but you have to get the paid version to save them. Also, it renamed all my pictures to 'my beautiful pictures' which totally screwed up which ones I had to recover. I had 600 files at the time, 450 disappeared.
PC Inspector: Not very intuitive and language is too geaky: 'cluster', 'logical/physical' drive. We must remember when we find ourselves in a panic over loosing files, it's no time to learn new terms.
Recuva: Awesome. Very intuitive. Recovered almost all of them. Unfortunately, the ones Undelete found were renamed which put everything out of sequence and I couldn't tell what was still missing.
Photorec: Awesome as well. DOS only, from what I could figure out, but remember I was in panic mode. If someone who has used this knows of a version with a GUI interface, let me know. However, I was able to follow the DOS prompts with no problem. DOS instructions were very straight forward. There is a very good tutorial at irongeek.com. Google 'photorec', then look for the irongeek website.
Now I'm off to donate to via PayPal to these 2 outstanding programs.
Recuva can also be used as an eraser, with up to 35 passes!
Generally if you have the resources it is best to make an image of your drive and try to recover the info from that. That way your data is safe on the original disk.
I ended up deleting a set of Outlook pst files when I used a backup program that deleted files on the backup drive not found on the source drive. DUH! Woke up one morning with a sickening feeling realizing I'd done that the day before. PC Inspector file recovery found in tact and restored. BUT you MUST write the saved file to ANOTHER drive. They also do not want you to install PC Recovery on the same drive from which you are recovering. So, for me this was ideal as I backup redudantly to two external USB drives and wanted to recover data ON those drives. I recovered from one and saved to the other than matched the drives. Right now I'm doing a cluster search for "lost" files and that is proceeding well. GREAT product.
I've used the utilities listed in this article to varying degrees of success. Personally I think it is important to note that any file recovery software should really not require an installation in the OS. The installation itself could damage the file you are trying to recover.
Photorec (Posted by anonymous) is a part of the testdisk suite of utilities on linux. The testdisk suite can run on Windows, Mac OS X, Linux, Sun and many more. It does not have a GUI frontend at all. Does anyone have an opinion on whether or not a GUI is required?
I use PhotoRec
it's a brute force scanner, not very user friendly
but no other free product i tried finds so many files as this one.
Recuva has an advantage over PC INSPECTOR File Recovery: it can handle unicode filenames without problems. PC INSPECTOR File Recovery only shows those characters as "?", which means that they need to be renamed and that makes really hard to identify the recovered files. Recuva doesn't have a problem with uncode characters. Since I always keep files with Chinese and Japanese characters, I recommend Recuva over PC INSPECTOR File Recovery.
I'm using the freeware name EASEUS which perform very well and flawless, but unfortunately it do not support the USB. This PC INSPECTOR is workable yet a bit slow. Anyway it is free....not expecting much as long as it is working fine. Bravo to the freeware :)
EASEUS Data Recovery isn't free, it's $50.
help i have 2 portable hard drives i put files on there and now there not i know there there so i can i get them back? email me at i need a free porgram to do this thanks

Today I inadvertently deleted three pictures from files my SD memory card. I didn't save any more pictures to the card so I thought it would be child's play to restore the deleted photos. Wrong.
PCI Inspector File Recovery restored a lot of files but none of them would open. PCI Inspector Smart Recovery found and restored lots of pictures including two of the three I wanted, but the bottoms were cut off. The third picture restored as a thumbnail only.
Then I tried BadCopy Pro, which is not free but which is highly recommended. The results were pretty much the same as PCI Inspector Smart Recovery.
Finally I tried PhotoRecovery Wizard, also not free. It restored my pictures perfectly and worked rather quickly too.
I'm wondering if there's a problem with my memory card that made it so difficult to restore recently deleted pictures.
I have to agree that Recuva has always been disappointing. I have been keeping it around for its portability, but it has failed me twice. Last time, I finally gave up on it and deleted it. A product in this category has to be reliable if NOTHING else.
PC Inspector has its flaws but at least it seems to work. Was successful last time where Recuva failed.
Downloaded and installed Recuva and Diskdigger (I prefer files that don't require installation or make registry changes). I run XP Pro Sp3. Deleted a 1.4MB Word document. Neither program could even find it, let alone recover it. Didn't run a "deep" scan, but on the other hand I ran these utilities immediately after deleting the file from the recycle bin. Very disappointing results.
DiskDigger received high marks on page 60 of PCWORLD 6/2009

Recuva for hard disk and CD Recovery Toolbox Free for:CD,DVD,Blue Ray,HD and this is total free.
I tried Recuva but it would ot open files. It would not recogonize the files. Also, it did not find the files I was looking for.
I wanted to recover a load of photos I had deleted on my Nokia n96 phone. I plugged it into my PC and used PC Inspector (PCI) Smartrecover and it found them all!
Great program and easy to use.
It sound great!!!
But could you tell me this program can recover videos files which had been delleted by Nokia N96?
According to their website, Smart Recovery can reconstruct video files (as well as pictures and sound).

Hi everyone. I was wondering what's the best free software to repair a hard drive which has a lot of bad sectors on it? Is there any software that will recover data (pictures, MP3s etc) from a damaged drive?
Many Thanks

No free equivalent to the deep hard disk program SpinRite by security expert Steve Gibson.
Moderator's Comment: Link removed: Spinrite is a commercial product.
There's a much bigger list of completely free file recovery / undelete programs at this site:
http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm
Given the multi-tasking capabilities of the current software and hardware I'm surprised that no-one seems to be producing a non-commercial alternative to the enhanced recycle-bin Undelete utility from by Norton, Executive and others.
A program was originally developed by the Sysinternals team for Windows NT4 before they joined Microsoft (FUndelete) which saved ALL deleted files to an alternative recycle bin, but since then has not been supported. It was usable with XP but was in need of further development.
For PHOTOS, PC INSPECTOR has another free product called "SMART RECOVERY" that will scan drives and memory card looking for the typical structures of main photo and video formats. It is thus better that its general counterpart. Used it on a memory stick that could not be read nor formatted and got almost all the content and even some photos that were several years old.
Highly recommended. Download here : http://www.pcinspector.de/Sites/smart_recovery/info.htm?language=2
I agree. I had forgotten all about this software.
Several years ago, I had gotten my first digital camera and was getting ready to transfer photos taken on my vacation to my computer and was going through the photos to delete the bad ones. I hit the "delete all" by mistake and thought I had lost several hundred photos.
I found Smart Recovery and was able to get back all of the photos.
I recently had a large and important text file "disappear." Neither of the two programs listed here helped. (Nor did Restoration.)
What finally did work was using the hex editor Hxd (see Best Free Hex Editor section) to view the entire disk. I was thus able to reconstruct the file. (Not as easily as I could have; I had to do a bunch of cut-and-paste and search-and-replace. Either Hxd needs additional functionality, or I need to understand it better.)
So:
1. If I could do that, why couldn't the unerase programs do so? Yes, I realize they're free, and I am grateful for what it is they do, but is it too much to ask for the functionality that Norton Utilities provided over 15 years ago?
2. If you know what you're doing, keep the RAW disk editor option in mind, as a last resort.
Additional notes:
1. Can anyone suggest any other free undelete programs I could have used? They would obviously need to include a "words within file" feature.
2. Christopher: Cute page setup, with the sticky notes etc.
3. Suggestion for the administrator: it would be useful to provide (or to require) a name field for the comments. Makes discussions much easier.
PC Inspector's File Recovery worked for me. I had a corrupt compact flash card from my camera. Win XP said it wasn't formatted, but File Recovery read the disk anyway and recovered all the images on it. 3 were in fact messed up, but thrilled with getting everything else back.

Resently I lost a lot of of jpgs, but only found out about it after a week and some write overs. I tried both Recuva and File Recovery. They found some stuff, but nothing that I was looking for. On the plus side was that they tried to place them in the folders they came from. After searching around I found Photorec. It found piles of stuff including most of what I had lost. A big plus is that it is a stand alone product with a small footprint, very quick, and will put it anywhere. It gives you a wide range of file types to look for, and lets you look at either just the free space or the whole drive. There are versions for Dos/old Windows, Windows, Mac, OS2, linux, etc.
The cons with it are that it runs in a command shell. The format used for identifying drives is linux based. They online help/FAQ is very poor. Overhelming number of files recovered. If no name is atached to it a alpha numaric name will be assigned. they are place in folders named by photorec according to order of files discovered and the possible path of the file is not even looked for.
Considering the results you get at finding files it is well worth the effort of finding out how photorec works. By far the best recovery I have found. Photorec at: http://www.cgsecurity.org/wiki/PhotoRec
Recuva and PC INSPECTOR File Recovery both appear to write settings to the registry even when installed on a USB key, which sucks if you have to recover anything from your C: drive.
I made an error, Recuva can be set to not write settings to the registry via options > general > save all settings to ini file.
Can you use these software to recover photos from a cell phone?
Photorec ... which comes with Testdisk now i think... might be of use to you.

I want to say something about the long statement "Data Recovery Standards: 12/15/2008 15:38." I wrote it. I posted it to the Microsoft forum and to my great sadness was verbally and viciously attacked by their M.V.P.s and the post was deleted, supposedly as spam. They also said I was lying etc. etc. So I wrote a handwritten letter to the Microsoft President, Steve Ballmer. They could have said; "Write it again without the names of the companies" but they didn't. One man became so timid He asked "Is there a place I could read the rules; do(sic) and donts I do not want to offend anyone." I did not want to advertise anyone. I have no connection to any companies named. I found extraordinary info,got excited and wanted to pass it on. "Remanence: from Marriam Webster: "The magnetic induction remaining in a magnetized substance when the magnetizing force becomes zero."
Gizmo was one of the first sites I went to on a regular basis and always was impressed with the civility. R.C.F.
Data Recovery Standards:
Simple Overwrite, 1 pass. D.o.D 5220, 3 passes. N.S.A., 7 passes. Gutmann, 35 passes. In reply to "Can overwritten data be recovered?" Yes. As data is written to tracks and recovery programs aim at those tracks which are overwritten, the best data recovery teams sense what data is between the tracks. The name of this is Advanced Hardware Electromagnetic Remanence Techniques. No matter how many times data is overwritten Remanence remains. An Example: 320 Gig HDD with 999 day Internet Explorer Browser history, 46 weeks long, overwritten 2 months. 29 Recovery programs including all mentioned here, 13 Binary, Cache, and Index programs, and 6 Index.Dat Analyzer's were first attempted in recovery. Results were unintelligible. Sent to Aero Data Recovery,"Never seen anything like this". They referred HDD to ESS Data Recovery. Results: 400,000 lines of excellent readable data. HDD had been overwritten 3 to 4 passes. ESS could recover to 7 passes. To truly rid a HDD of data it must either be Magnetically Degaussed or Destroyed. There are many examples of this. M.I.T. saved data from 158 overwritten HDD. Cost for ESS recovery, $835.00
I recommend to use Recuva first, with the 'Deep Scan' option turned off, recovering only deleted files in 'Excellent' state. If this doesn't recover all the file(s) you wanted, then try PhotoRec. PhotoRec will take much longer because it ignores the filesystem and instead looks at the underlying data, a process called file carving. There are situations where the filesystem has been damaged or formatted, and thus file carving is needed for recovery. Recuva with the 'Deep Scan' option turned on also does file carving, but PhotoRec may be a better choice for file carving as of this writing because it may be able to carve more types of files than Recuva. See http://www.cgsecurity.org/wiki/File_Formats_Recovered_By_PhotoRec for a list of file formats that PhotoRec can carve. See http://www.recuva.com/download/version-history for a list of some of the file formats that Recuva can carve.
Both of these programs should be in your toolkit, and IMHO in the recommendations of this site.
