EDIT (2014-07-27): I could have this SD card again, and it seems to be faulty. Yesterday, I was trying it via a USB card reader. Today, I've tried it directly by putting it in the SD slot of my laptop, and I got thousands of I/O errors:

and gdisk -l didn't find any partition table, and lsblk output about the card:

mmcblk0                  179:0    0   3.7G  0 disk

A bit later I tried again, and the card was recognized:

gdisk -l /dev/mmcblk0 found only a MBR partition table, but the second partition table overlaps the last partition.

mounting a SD card without a partition

I try to mount a SDHC card under GNU/Linux. Unlike what happens usually, /var/log/syslog doesn't mention sdb1, just:

Jul 26 16:07:53 xvii kernel: [  159.404842] scsi 6:0:0:0: Direct-Access     Singim   SD Card   MMC/SD 1.4F PQ: 0 ANSI: 0 CCS
Jul 26 16:07:53 xvii kernel: [  159.405115] sd 6:0:0:0: Attached scsi generic sg2 type 0
Jul 26 16:08:01 xvii kernel: [  168.239600] sd 6:0:0:0: [sdb] Attached SCSI removable disk

Moreover fdisk -l /dev/sdb outputs nothing. What should I do?
