You can not recover if you let a full format complete. It depends if the full format was allowed to complete. A full format overwrites data. Overwritten data can not be recovered. So in case the format operation had the chance to complete, you can stop reading here, nothing and no one will be able… Read More »
Probably Android phones are the most common devices to take photos with nowadays often stored on a Micro SD Card. Consequentially many lost photos will be on Android devices. Photos can be on: Internal memory (Micro) SD Card Although many want you to believe it is easy to recover the lost or deleted photos and… Read More »
Case: SD Card is accidentally formatted in Windows (10). Some popular recovery tools are tried; Recuva from Piriform, Recoverit Photo Recovery from Wondershare and Stellar Photo Recovery. Recoverit and Stellar Photo recovery are basically nothing else than dumbed down versions of their generic data recovery tools. They fail to detect any data. In this video… Read More »
When you discover photos on your SD card are corrupt you should: Do as little as possible (read: nothing) with the card. Do NOT run chkdsk on the card itself! Create a disk image of the card immediately! There are free and paid ways to try to recover or repair your photos. So I’ll be… Read More »
Unfortunately it is a common problem that you are unable to open recovered photos after using file recovery, undelete or photo recovery software on a SD card. In this post I will make some assumptions: Photos are on a memory card and therefor: File system is a variation of FAT (FAT32, exFAT) File type is… Read More »
Not a week goes by where I am not confronted with loss of digital photos caused by fake memory cards. The sad news is that as these photos were never actually saved to the card they can’t be repaired nor recovered by tools like JPEG-Repair or JPEG Recovery LAB. A 32 GB card that you… Read More »
Stellar JPEG repair is now Stellar Repair for Photo I noticed Stellar renamed their photo repair tool from ‘Stellar Phoenix JPEG Repair’ to ‘Stellar Repair for Photo’. ‘Photo Repair’ suggests that rather than being limited to repairing JPEG, it also supports other digital photo formats. I visited their website and downloaded the new version. This… Read More »
Recovered photos are corrupt and won’t open after you tried to recover them using undelete, file recovery of photo recovery software? Here’s a few things to try. There are a huge number of JPEG recovery and undelete programs available on the web, many even for free. However, the vast majority of these can only handle… Read More »
There’s basically three things that can be wrong if a JPEG opens but is partially grey:
1. File is too small. Let’s an average JPEG shot with same camera and settings is 4 MB and the ones that are damaged are like 1 MB or 2 MB. Then probably half the data is simply missing. These files can not be repaired.
2. Normal file size. Either part of the file does not contain image data or file does contain image data but is interrupted by some invalid data.
If part of the file does not contain image data then this is sometimes easy to spot using a hex editor. All of a sudden ‘random’ binary data stops and changes to FF FF FF or 00 00 00 etc.. Repair: Impossible.
In case the data is however is there but it is interrupted repair is often possible. JPG-Repair tries to detect and will try to get rid of the invalid data, however this does not always work. Current version detects invalid JPEG markers, common damage due to bad sectors and some type of corruption I observed a few times with images shot with certain Samsung phones.
How to repair a corrupted JPEG photo may seem a simple question but the answer isn’t. Many people seem to expect to run some JPEG Repair software and that fixes it. And that’s what many of my competitors promise. If only it were that simple. Now, let’s take this one step at the time to… Read More »
