Host ID SD Card Generic 4GB

Plug the SD card into a USB reader (or native port if the host PC offers one) and connect it to a Linux workstation PC. Newer distributions include a utility called 'lsblk' which lists all block devices like a USB SD card adapter:

lsblk

 NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
 sdY      8:0    0   400G  0 disk 
 ├─sdY1   8:1    0   398G  0 part /
 ├─sdY2   8:2    0     1K  0 part 
 └─sdY5   8:5    0     2G  0 part [SWAP]
 sr0     11:0    1  1024M  0 rom  
 sdX      8:32   1   3.9G  0 disk 
 ├─sdX1   8:33   1   7.9M  0 part 
 ├─sdX2   8:34   1     2M  0 part 
 ├─sdX3   8:35   1     2M  0 part 
 └─sdX4   8:36   1   3.8G  0 part  

In this case the SD card is 4GB, so sdX is the target device. Note that "sdX" is not the real device name, it could be sda, sdb, mmcblk0, etc., so be sure to match up the real device name with the SD card. Technologic Systems is not responsible for any damages cause by using the improper device node for imaging an SD card.

Alternatively, after plugging in the device after Linux has booted, the command 'dmesg' can be used to print out the kernel log. When a new device is added to the system, information about it will be appended to the kernel logs. For example:

dmesg | tail -n 100

 scsi 54:0:0:0: Direct-Access     Generic  Storage Device   0.00 PQ: 0 ANSI: 2
 sd 54:0:0:0: Attached scsi generic sg2 type 0
 sd 54:0:0:0: [sdX] 3862528 512-byte logical blocks: (3.97 GB/3.84 GiB)

In this case, sdX is shown as a 3.97GB card. Note that "sdX" is not the real device name, it could be sda, sdb, mmcblk0, etc., so be sure to match up the real device name with the SD card.
