Plz help me regarding this memory card. (SONY Memory Stick PRO 4GB)

Its from the Sony camera. when i attach it through card reader or via sony usb camera cable, it gives an option to format. But card is detected fully in Rstudio and DMDE, it shows 3.8 GB, upon scanning it shows NO DATA (not a single file). i have read sectors in Win Hex, i dont knw much about it but i just tried to look on sectors and expected random characters like its normally, but it gives the value FF in all. nothing else.

What could be the cause? and possibilty of data recovery? and how come all data becomes FF?

Probably been wiped. Need to remove and read NAND chip to be sure (which isn't DIY)

but how it is wiped like this that memory card is showing exact capacity with sectors filled with "FF". how can all this happen in a sudden? can it be a virus?

I'm with PCImage on this one.

Agreed it doesnt look good.
As pcimage has stated the NAND chip would need to removed & read in a NAND reader to confirm

You could try to write something to the very last byte of the card. After saving it remove and reinsert card. If the change is still present, data is likely gone. If the change has not saved, send to a pro

if there a electronic fail then it can wipe the card clean

only way is to read the NAND chip as pcimage said

and most probably securely formatted, if you are familiar with Winhex, have a look and see to confirmed

bad luck, but good luck really finding why happened
