Our JPEG Repair Service will fix corrupt JPEG files. JPEG is a popular image format utilized by many consmer digital camera's and smart phones. Due to the nature of JPEG's storage of image data, corruption can easily occur. Corruption is often first detected by the inability to display digital photos (not a valid image file, too large or corrupt). This is often caused by structural damage: missing or corrupt 'markers'.
The second type of corruption is in the (compressed) image data stream itself. Although the image can be viewed and even edited, colors are distorted and portions of the image may have shifted.
We developed our own JPEG repair tool kit to make the process as efficient as possible, although the repairs require the human eye and manual editing of binary data. This is why we can often repair JPEG files that automatic JPG repair tools can not.
DiskTuna offers a freeware defragmentation and disk optimization utility, which is where the name DiskTuna actually originates from: DiskTuna (as in Disk-Tuner). DiskTuna is a tiny and free disk defragmentation and optimization software, that will only run when you need and want it to. DiskTuna does not install background services or startup keys. A unique feature is it's ability to create shortcuts to easily start 'jobs'.
For example: Defrag the c: drive in the background, minimized, and close when done. It's Optimize feature will significantly decrease Windows boot times and will place most frequently accessed files in the fastest area of the hard disk (outer platters). DiskTuna offers a VSS safe-mode to reduce the effect of defragmentation on Shadow Copies.
Unique: DiskTuna will pause when it detects a hard disk gets too hot.
Runs on Windows XP and higher and requires administrative rights for direct disk access.

I use System Restore Explorer to recover files from restore points and find it works very well.

Hi ilikefree,
Yes, if you have shadow copies/previous versions of a file then that's better than any undeleter. It's like having a backup.

I haven't "tested" the product but ran it using a monitoring program and I can say that it seems to be truly portable- a rarity these days (nothing was even added to the Windows Registry). To the author I must tip my hat! Thank you joepvansteen and GOTD!

Useless or beyond my abilities :-)
Unzipped on c:\desktop for trial
Deleted one file (....exe from my e:\data partition, emptied recycle bin and immediately set the tunawhatnot to hunt for it. Search did not take long, offering a gigantic mass of retrievable files. OK, narrowed down to *.exe and date.
Dates starts in 2006 (probably when the recovery masterpiece was created). As I knew my file was from early this month I used during previous 31 days. The one single find was not for the file I wanted - so I'll send today's offer where it belongs - the bin.

Sigrid.DE,
Just because a deleted file can not be recovered, it doesn't make this or any other undeleter useless. It made it useless for recovering that particular file.
It is not a given that a deleted file can be recovered. It's something you can try using some undelete software.
Having an undeleter installed, means you have increased your chances of recovering a deleted file. Binning it decreases this chance again.
Save | Cancel
joepvansteen,
I agree, to a point. I'd think that if the file were deleted immediately after the install of the recovery program (which ever RC it was), it should be easy to find and recover. If ANY write to the disk after the file delete occurred, then that might drop the chances of locate and/or recover.
I guess a better test would be to install the file to a USB per their instructions and try the experiment again.
Save | Cancel
joepvansteen,
granted, but do you honestly believe that one particular file, within less than one minute deleted and emptied from the recycle bin cannot even be found anymore?
That is what I call failure in such software.
Save | Cancel
Sorry forgot to add, anything in the recycle bin can be retrieved.
Save | Cancel
Hi Sigrid.DE,
Well, all I can say is that I have seen that happen. Of course when I wrote the software, I have tested it thousands of times: copy a bunch of files somewhere, delete them (SHIFT DEL) and scan ...
All the software does is:
In case of NTFS: Parse MFT and gather ALL files marked 'not in use'. A file is either marked in use, or it's not. It's binary.
In case of FAT(32): Scan directory entries and gather all entries of which file name has first character replaced by E5h.
What was the file system on the drive you tried this on?

Worked for me. Downloaded fine. Did a small test deleted 2 small notepad files from "D" drive, 1 to recycle bin and 1 permanently deleted and it recovered both.
But the files are simple files that were just deleted. There is no installation. It is just placing the files where you choose during extraction. So either choose a convenient place or take note of the default location.

timb12957,
Can't do anything about that unfortunately, GOTD made the setup. I am not sure if it allowed for me to sent you just a ZIP file ...
Save | Cancel
joepvansteen,
Some of the giveaways on this site have been provided without the GAOTD wrapper, so it apparently is possible for the developer to request that option.
As I mentioned in one of my other comments, the wrapper's pointless in this case anyway, as it does nothing to prevent reinstallation when there's no actual installer for it to protect.
Save | Cancel
timb12957, I haven't tried it yet, but my guess would be to try making a folder for it on the usb drive, downloading it to that folder, then extracting it to that folder before running setup.exe. Usually you need to extract files to the folder holding the zip file, even when it is not a portable application, and is being installed on c: drive somewhere. Hope that helps -- I'd like to know because I plan to try it later.

Dear joepvansteen,
We do not imply any restrictions on that :) We've made the setup to prevent unauthorized installations after the end of the giveaway, but you are always free to share the original installation file with our community if you feel that it is required. If you wish, we can replace the protected installation file with the original .zip archive. Please, contact the manager who arranged your giveaway and we will replace the files ASAP.

Always yours,

Why is it that every undeletion utility always provides those same don't-put-this-on-the-drive-you want-to-recover-from instructions without bothering to make it clear that that only applies if you want to recover files that were deleted before you acquired the software?
The issue there is that when the OS deletes a file, it marks the former contents of that file as free space so, whenever you write something to that volume, there's a chance that it'll overwrite the contents of the deleted file. It's therefore risky to add anything to a volume that contains deleted files you want to recover.
Unless this program does something stupid like write things to its install dir as it's working (and it certainly shouldn't need to do that), it should be perfectly safe to run it from the drive you're recovering from so long as you installed it there beforehand. In fact, it's a good idea to keep one or more undeletion utilities installed on your computer for this very reason. (Annoyingly, these sort of misleading instructions tend to stop people from doing exactly that because they give people the mistaken impression that it's not safe to run such programs directly from the computer's hard disk.)
Apparently, whoever wrote the instructions is making the unwarranted assumption that no one ever acquires the program until after they've accidentally deleted some file(s) that they want back.
In fact, the instructions provided above for this particular program are worse than usual in that they specifically tell you to put the program on a USB flash drive, which means they're making additional unwarranted assumptions regarding both the location of the deleted files and your hardware setup.
Save | Cancel
Jim Stone,
You are right! If you're not downloading this because you have just deleted a file you need back, then you can download and save it anywhere you want.
Thing is, IF you just deleted some files, I guess a straight forward instruction 'do not install bladibladibla' works better than describing all kinds of conditions and install instructions.
But, yes you are correct.
And I agree with the idea that it's a good idea to keep some undelete tools handy at all times.

joepvansteen,
"If you already have deleted files you need to recover, put this program on a different drive than the files were on" hardly strikes me as overly complex or "describing all kinds of conditions and install instructions".
My problem with the sort of instructions provided at the top of this page isn't that they're overly simplistic but rather that they're actively misleading.
As I said, they give people the mistaken impression that you can't safely run this sort of software from your hard disk.
Save | Cancel
Jim Stone, No. You do not install and run a program from the drive that you want to recover deleted files from because any activity on that drive can possibly overwrite the information that you trying to recover. Recovery of information depends on not having overwritten the information that you want to recover it has nothing to do with when the file was deleted.
Another point is fragmented files are difficult to recover because cataloging a fragment locations changed at the time that a file was deleted. Writing new information into the registry with drive activity further complicates file recovery.
Save | Cancel
kc4cop, best form is to make an image of the drive that you wish to recover files from and work on the image rather than the actual drive. That is recover the files from your image. This is a safety factor to keep from writing additional files to the drive that you trying to recover files from.
Save | Cancel
kc4cop,
I think you either failed to read my entire comment or failed to understand it.
It very much matters when the file was deleted relative to when you install the undeletion software because it's only risky to add new files to the volume after the file-to-be-recovered was deleted.
You can't safely install the program on that same volume if you already have a deleted file that you want to recover because the act of copying the program file(s) to the volume could potentially overwrite the very data that you want to recover.
On the other hand, if you already had the undeletion software installed on that volume before the file got deleted, it's perfectly safe to run it from there because doing that only involves file reads and those won't overwrite anything.
You understand?
(You do realize that disk activity in general does not necessarily overwrite anything, right? It's only risky to do things that actively consume free space, like creating new files or appending additional data to the end of existing ones.)
I have no idea why you mentioned file fragmentation or registry access, as neither of those have anything to do with the issue.
Save | Cancel
Hi kc4cop,
Just a quick remark on recovery of fragmented files:
When 'un-deleteting' from NTFS, file fragmentation is not an issue when doing a file system based (so not RAW of file carving) recovery.
When deleting a file in NTFS, the complete run-list of the file remains intact. As long as this info is available, and the actual clusters do not get overwritten, fragmented files on NTFS should recover okay.

Jim Stone, I'm thinking it might be a different story here because this is a portable app and is not installed on C:, as long as you don't try to recover files from the usb drive you put it onto.

Hi Jim Stone,
Make a suggestion ;)
English is not my native language. I am open to suggestions. What would be a good way to explain to not install/copy the software to a drive containing the lost files.

Hi kc4cop,
In general indeed the first rule with data recovery is: Create an image file (or clone the disk. Disk to disk, disk to image, doesn't matter).
Problem I see is that:
- Creating an image file of a 'live' volume will take time, and probably more time than
- Just scan the drive for deleted files and recover them.
If you want to go the image file route and the files are on a 'live' volume, you need to 'disconnect' the live volume ASAP.

beans, portable programs can, by definition, be run from anywhere, including C:.
Save | Cancel
joepvansteen,
Well, I already gave a simple example above, but I suppose we could get a bit more elaborate:
"If you already have deleted files that you wish to recover, you should not put this program on the same drive as those files, as the simple act of copying this program onto the drive could overwrite the very data that you want to recover. Put the program on a different drive, such as a USB key, instead.
If you're simply installing the program to have it available for future use, then it's perfectly fine to put it on drive C: (or anywhere else you please) and run it from there as needed."
