Ubuntu – Ubuntu won’t mount SD Card

14.04mountsd card

I have Asus X552V with Ubuntu 14.04 64b.

I tried inserting 4GB Transcend SD Card into Card Reader, but nothing happens.

As I was directed to Why does Ubuntu not detect my SD card? this question, I tried doing what it said, but nothing changed.

Then I tried doing sudo fdisk -l and the output was: 

Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors
Units = sectors of 1 * 512 = 512 bytes

Disk identifier: 0x00000000

        Device Boot      Start         End      Blocks   Id  System

So obviously, I can see my SD card here, but it seems strange to me that disk identifier is 0x00000000, and that it took about 2 minutes to get this information.
Is it a Ubuntu bug, or could it be a SD Card issue?

Update: I tried the same SD card with my other laptop also running Ubuntu 14.04 and it works with no problem.

When I run GParted with SD card inside, it will never scan all drives, but it will when I remove it. blkid also runs forever with SD Card inserted

Panasonic cards are formatted using exFAT. To automatically mount exFAT filesystems, install following 2 packages:

$ apt-get install exfat-utils exfat-fuse

Cheers.
