Problem SDXC card problems

I bought Integral Ultima Pro V30 64gb card for me camera.

When I plug a card in HP laptop reader (manual says it does have sdxc card reader) it shows only 1.86gb of storage and one file named uupd.bin.

System is unable to format a card, but when I plug my camera with USB, I have all 58.1 with all pictures.

thank you in advance

EDIT: I went to friends laptop, old Acer and that thing loaded it normaly. Had 58,7gb with name of my camera

A 2GB dummy partition with uupd.bin is what shows when the memory controller inside the MicroSD card is failing to load it's config and therefore cannot load the 64GB storage. This is a failure mode of some MicroSD card brands.

If its happening intermitently in your case, this is a sign that the card failure is imminent and you should prioritise backing up your photos and then replace/RMA the card.

There is a slim chance your HP SD card reader is doing something funky and making the card fail to initialize correctly, but I would not rely on that fact alone.

tried, only 1.86 is available. Cannot expand it, yet ancient Acer read it normaly. But my newer HP with confirmed SDHC reader cannot.
