Hi,

I'm ending there because someone told me there may be people able to help.
My SD Card, short story version: "I love taking pictures with my camera. I bought a PNY SD card ~3 years ago, I formatted it 5 to 6 times only. 2 weeks ago, I was using it in my camera and suddenly I was unable to see the picture just recorded on the card."
Since then, I've tried many thing to recover my precious pictures, I thought I was on the right track but everything collapsed this evening
My card can't be read by my 2 different UHS-II card readers but I succeeded to read it with an older UHS-I reader. I was happy to make an image by using ddrescue, even if the process took 6 days to read it at a very low bandwidth of 0,5Mb/sec. Then, I tried different tools including testdisk, dmde, photorec, ... nothing worked. No sign of any file. I finally wrote a small python code to read the image byte after byte and it confirmed my greatest fear, the image is full of one value: 0x55. So I suspect the card is currently failing at a hardware controller level (returning a uniform 0x55 pattern on all read attempts), which indicates I guess a physical failure, not a logical file system corruption.
I am very sad and disappointed as you can imagine.
I would be grateful to anyone having some useful experience to help me bringing it back to life. It doesn't have to last long, there may be 30 to 60 Gb of pictures on the card, I'm only requesting the opportunity to copy my pictures. Thus, if someone have skills on this kind of PNY SD card, please please please, help me

Use a USB cable to the camera to access images instead of removing the card. My P15 has a build in D card slot and for other models I use a USB reader. I use mostly Sandisk but other vendors are built from the same standards.

I have many tools for various memory cards. Still there are some limits to what can be done. If the NAND is damaged the risk for loss is higher. I use a Sandisk Extreme SD card for file history in Windows 11. Still works fine.

The NAND on SD cards etc is built for mobile devices while USB sticks are about the same.

Last time I was asked to recover a card, took my machine several hours.
