I purchased a CUBE microSD/TransFlash to use in my mobile phone for music. I downloaded music to my computer from Itunes and attempted to transfer it to the SD Card. I will not let me saying that the disk is "write protected". What can I do to remove the write protection off of the SD card so that I can transfer my music to the SD card?
Your card reader may not be working correctly.
I was like you before. Inserted my MicroSDHC into a cheap card reader. Tried to copy files. Sometimes succeeded, sometimes write-protected.
But then I borrowed my friend's branded card reader and no problem whatsoever!
So I got SanDisk MobileMate Duo and the problem went away. Works like a charm. Transcend P5 is also quite decent and it's cheaper than my card reader.
