So for the past few weeks I've been having some weird issues with 5 or so Micro SD and SDHC cards. I have a original Intel Macbook pro and a Asus EEE PC 1000HE. I have Micro SD cards ranging from 1gb cheap sandisk to 8gb class 6 transcend cards. None of them will mount in any of my devices. I have tried formatting them in Windows/Leopard and in linux using both ubuntu and gparted live disks. The cards mount fine in all operating systems but when I goto put them in my phone or in a DS or a camera they will not mount. I have also tried the internal sd slot on my EEE and 2 usb adaptors on my mac. Im completely stumped as to whats going on? I just dont see how new and old cards and 5 of them could be completely borked. Sorry so long Thanks in advance. I guess i should also mention that Im running snow leopard and it seems my issues may of started when I switched but im not certain.
