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 Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x2bfb4dc8 Device Boot Start End Blocks Id System /dev/sda1 * 2046 261904383 130951169 5 Extended Partition 1 does not start on physical sector boundary. /dev/sda2 261904384 1129629695 433862656 7 HPFS/NTFS/exFAT /dev/sda5 2048 58593279 29295616 83 Linux /dev/sda6 58595328 253904895 97654784 83 Linux /dev/sda7 253906944 261904383 3998720 82 Linux swap / Solaris Disk /dev/mmcblk0: 1973.2 GB, 1973231288320 bytes 82 heads, 17 sectors/track, 2764682 cylinders, total 3853967360 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/mmcblk0p1 8192 7811071 3901440 b W95 FAT32
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
