Got a few files on an SD card. It has now been running for over an hour. No screen appeared which helps to see the preview files before saving appears. Just the progress bar (green) and no indication of what is happening.
John
Hey Jhon,
Progress bar itself indicates that the software is scanning your SD card or hard drive, once scanning will complete, it will automatically shows your corrupted or deleted photos for preview, if you want to see the preview in the middle of the process, you can stop the scan process in between. Also if your SD card have lots of images in it, software takes more time to scan.
BTW which software you have been used to recover your photos, because in JPEG Repair Software their is no scanning process occurs, might be you have commented on different section of the knowledge base.
Please let me know if you have any other issues.
Thanks

Have added 10 files to jpeg repair for testing. It looks like working, friendly interface, easy to use. But the files did not recover, show msg (important marker missing), have copy to linux, run on linux and cabum bum is fixed... Anyway thanks for an effort to create that software...

Hi Al..
If you send me one of the non repaired JPEG file, then only I can let you know the reason why our software not able to repair your files.

Purchased Stellar Photo Recovery to try and recover photos on a SD memory card. I do not know what has happened to the SD card. I first put the SD card into my iMac and most of the pictures were visible but when I went to download them they were bright colors and the images could hardly be seen. I then tried using my camera as the card reader and hooked it put to my PC. Same issue. Some pictures were visible but when you clicked on them they became different bright colors and some with lines.
As stated above I purchased the Photo Recovery - it ran the scan and I could see my pictures. I was so excited and thought the recovery program worked. However when they were saved to the computer I had the same results as above. Hardly any of the picture images were viewable - only lines and bright colors where pictures once were.
Would appreciate any guidance you can give me.
Thank You

I downloaded the free Steller Phoenix Photo Recovery and have been trying to get it to work most of the night.
It starts and I can see 3 different jpgs that it found on the 3.5 floppy that I'm trying to get them from but between the 3rd and 4th jpg the program stops. I get the "Program Stopped Responding" error. Don't know how to fix this and can't seem to find a place, other than here, to post my problem.
I don't think this is the right area and I don't think I'll get an answer but I thought I had nothing to lose by trying.

Hi there, I purchased the jpeg repair product to deal with a number of pictures that apparently had file errors and ended up getting the same message as Al above (Jan 16, "Important marker missing. File can't repair"). Can you advise on next steps?
Thanks!
Jeff
Jeff
DONNA, The thumbnail information is correct but the area where data stored is corrupted. In scan results we show preview of files using thumbnail information. Stellar Photo Recovery recovers files irrespective they are corrupted or not. Suggest you to try Stellar Repair for Photo to repair files (only if Camera is saving files in JPEG format).
cassiereroni, We are always here to help you.
In your case, Create an image of the floppy and try recovery using image. There might be bad sectors in Floppy. In Image, there will be no bad sectors.
Thanks & Regards,

Good afternoon,
If a JPEG file cannot be repaired due the error "important marker missing" is that an impossible recovery?
I ask as I noticed in your comment to Al on Jan 23 you mentioned having him send you a copy of the photo which would not recover.
Please advise.
Thanks.
Jim
Hi! I have the same problem when trying to repair an image, a message Important marker missing. File can't repair, does it mean that the picture can not be repaired?
Ana
Hi Brad,
There is no file size restriction in demo or purchased version of the software.
Thanks
Amit Pandey
Hi Jim, Ana;
Whenever you see software shows important marker missing message it mean your file can't be repair with the software. It is basically due to wrong header type information.
A "Invalid .jpg marker" means that the internal header of the file is showing as .jpeg, but the file extension showing something else... or, vice versa. And if you see your file extension with JPEG, then somehow internal header of the file got changed or damaged.
The basic solution of this problem is to change the file extension with .jpg or change the file header. Changing the file extension is quite ease just rename the file with .jpg extension but changing header information needs some editing tool like hex editor or something else. But it required enough experience to understand the header information and to operate a hex editor.
In some cases software repair thumbnails of the actual files because it might be saved at different location.In that case it is quit possible to see the thumbnails when the file is totally damaged.
Thanks

Hex editor Shows only FF FF FF FF and nothing in my picture view....
what is it means?
Amit Pandey
Hi Naqash,
The header of the photo starts with FF. In your case, the header may be corrupt. Our software repairs the corrupt header of JPEG/JPG files. Download Stellar Repair for Photo software and repair your photograph.
I downloaded the JPEG Repair trial software and, on testing with some corrupted JPGs, it showed images with the Stellar Software text that could not be saved to examine them. I purchased your S-P JPEG Repair activation key and ran the test again. The resulting images were not processed because of a problem with the source file. The thumbnails were processed properly, although these were not previously damaged!
Can I send you a sample for your appraisal and examination. All 7,000 of my [photos were affected by a virus and I really need to recover/repair most of them!
Thanks in advance

Hi.
When trying to open a jpg file I simply get Invalid Image. I downloaded your trial software and tried it on one file. It gave me "1 Invalid File(s) Found. Failed to repair." Do you have a suggestion what I should do?
Is there anything in the paid version that will do a better job?
Can I send you a couple of files to look at?
Best regards,

Hi Ólafur

Yes, send me some of the files for review purpose.

Hi Amit,
Thanks for all your post the information's were helpful. I am facing one problem with my SD card, I have 32GB san disk SDHC 10C card which was having almost 8k jpeg files. I was able to recover around 3k files without issue and rest of 5K files were recovered and showing the data size in few MB which is expected, but I couldn't see the preview of the pictures. Then I used a demo version of Stellar JPEG Repair software and after a long running the software return invalid files. These files are very important to me is there a way to get these files back.
Your prompt response would be very helpful.
Thanks

Does it only really save repaired files as thumbnails? I thought they can be restored to original form and quality.
Lora Fonacier
Hi Lora,
JPEG repair software repairs corrupt or damaged files. In case, images are severely corrupted then it can extract the thumbnail of images without compromising its visual fidelity.
Amit Pandey
Results of JPEG repair are unpredictable. An serously damaged jpg file (2/3 unreadable) was perfectly restored whereas another jpg with a bug on the color table (making a shift on row/colums) has not been repaired (only the thumbnail was properly extracted, with the correct color table). What can I do? Thanks.
Herve
Hi Herve,
Stellar JPEG repair tries to repair all the selected corrupt jpeg files, if it finds any file is badly/severely corrupted then restores the thumbnail of that image.

i tried using the demo version to get some jpg files back. i go the feedback ' invalid file'. how dthis be resolved.

Hi,
Thank you for contacting us.
Please confirm us the order reference number or email address in order to verify the order details.
Further software works on the principle of "What you see, you can recover". It means if you are able to see preview of file in our software, repairing is possible only.
Hi - I purchased your product for repairing corrupt photos, the thumbnails look great, but the actual picture did not get fixed and instead has the area that was corrupt substituted with gray. Please help as I purchased this and have had no luck with your product.

Hello,
I have recovered my photo's. But i can not get a preview. Probably they are damaged. I purchased your program and let it repair. But with most of the pictures i get a message "advance repair". What do i have to do than? i did one photo and it asks to upload a newer one from the same device. The result is that i get a grey picture with nothing on it. Please help me!

Hello - My situation is similar to that of Mark Woudstra (March 3, 2019) -- I was able to recover my JPG and NEF raw photo files, and they appear to be of realistic file size, but my Win 10 computer said "It looks like we don't support this file format." However, I AM able to open other JPG and NEF files, so I know the computer DOES support those file formats.
I purchased the Stellar Repair for Photos and ran it on all recovered files. After the first round, the program led me to "Advanced Repair" of all of the JPG files. I provided a sample JPG taken from the same camera, and it ran through the Advanced Repair process. However, the resulting JPG files were completely gray, and were only 1KB in size.
I did NOT receive any "invalid file" or "important marker missing" error messages.
Please advise. Thank you!

I have a problem of unreadable jpg files using my PhotoStyler image editing software with "some recent" jpg images. For example, images from my Pentax 2005 to 2010 cameras are totally readable, but not from my latest Pentax SLR cameras. In contrast, the jpg images are totally readable from my new 2019 AKASO EK7000 Go-Pro 4K Action Camera and from my 2019 Pacific Image PowerSlide X Automated 35mm Slide Scanner. Clearly my latest Pentax cameras are adding or deleting some format data that PhotoStyler needs to open the files. In contrast, my newer image editing software (PhotoShop, Paint, MS Photos, etc) don't have any problem opening all of the photos...thus they're not "corrupted." They just have some late addition that is making them incompatible with PhotoStyler.
I'm trying to find some batch conversion software that will allow me to view my Pentax SLR photos using my PhotoStyler...which is my preferred image editing software. Will Stellers jpg software do this? Is there a way to find out before buying the software.

I just purchased your product and tried to recover JPEG files. So far it has not worked. When I try to open the file using different photo viewers I can see nothing, just the , "It looks like we don't support this format". I followed the directions per your website and the help section. I can't see the image before or after the recovery process. I used the advanced repair and saved the file and all I see is a gray box. Help please.
