I have a friend's 2 GB micro SD card from his phone. He says it doesn't work, and asked me to fix it.
When I put it in a card reader, the light on the card reader comes on, then a few seconds later goes off. The PC anti-virus meanwhile is trying to deal with a virus, but then everything related to "windows explorer" locks up.
The virus software freezes
Windows explorer freezes
The window that normally comes up asking what to do with a USB device doesn't show up
If I'm using the tools in Windows disk management, they lock up.
If I disconnect the card, everything happens...
The virus software tells me it has dealt with a virus (but never got to scan any more)
The window about what to do with a new USB device pops up.
Windows starts working again
I can't try to "fix" whatever is wrong, as I can't access the card for more than a second.
I can't format the card, as when it's connected it won't allow anything to be done to it.
There is nothing really important on the card. I'm just struggling with it, because I want to know how to deal with this in case it ever happens again.
The best suggestion I found (I think) was to open a command prompt, and do:
chkdsk h: /r
...which should have checked the file system and repaired anything that was damaged, but since nothing seems to be able to communicate while the card is connected, I can't even do this.
Anyone have any advice?
I've cleaned the contacts, no change.
I've used two computers, no change.
I've used the card plugged in directly, and also with a SD card adapter - no change.
