I'm using Transcend Micro SD Card. When I try to copy some files from my system(12.04), it's getting write protected and also unmounting the device. I'm unable to copy files to it.

Rahul, First Check that whether You have locked MicroSD card using white lock which is located on side of Adapter.

There's no lock for the SDCard holder. Are you saying that the problem may be with SDCard USB holder ? –  Rahul Jan 1 '13 at 16:22

This is a duplicate. Please refer to my answer on /questions/213889/

basically, just run in terminal sudo mount --options remount,rw <the SDHC drive, /dev/sdb for example, find it using fdisk -l>

In case, if you are using Sandisk, please do the following (If the lock switch is not on lock):

  3. Slide the switch up to unlock the card.
  4. Try to transfer files into the device.

Yes it is strange and yes it works, as per this source.
