Hello. My M3 Perfect has had a problem with the SD driver for some years. One of the pins/prongs broke off in the drive, but luckily I could jam it back in and it would read the card again. A few nights ago, the prong slid out again, and I lost it, so I decided to disassemble an old SD reader and use prongs from there, but it still won't pick up the SD card. I believe the connector isn't picking up the prong correctly. Is there anyway I can fix this? Would soldering fix this, or would it not be compatible with the prong? Please help, as I really don't want to have to retire my M3. It's been the best flash card I ever had and I'd rather not have to downgrade to a lesser flash card. Thank you.
