I have a sd card which is full of data. I’ve inserted my SD card in some system that was full of viruses, and my data in SD card have been deleted. I need to retrieve that data.
Shouldn't the virus be removed or rendered harmless before any attempts at data recovery? Otherwise the virus will be propagated to yet another PC. Any data recovery should be attempted on a "sand box" PC.
If the cause of the loss of data is a virus, then it may just be hidden rather than deleted. The easiest way to detect and fix it is to download Unhide from bleepingcomputer.com.
If this doesn't work, try downloading Recuva or one of the other recovery packages on our Best Windows Software list.
you have to try some recovery tools.
