Brand new to anything Linux!!

Have an Asus Eee 900A PC with a 4GB Asus Phison SSD.

Running a LiveCD with Knoppix 5.1 from a USB CD ROM, since the netbook does not have one.
Also, a 4GB SD card is inserted in the SD slot, and it is recognized in the BIOS.
Want to create a persistent Knoppix disk image on the SD card.

Went to Configure > Create a persistent Knoppix disk image, and in the prompt where a partition is selected for creating the image, the following options appear:
/dev/hdc1 Unknown [ext2] 3333MB
/dev/hdc2 Unknown [ext3] 494MB
/dev/hdc3 Unknown [vFat] 7MB
/dev/sda1 USB SCSI HD Partition [vFat] 3900MB

Is /dev/sda1 the SD card?

Would appreciate some help identifying which one is the correct partition pointing to the SD card. Don't want to erase the Phison SSD!!

Thanks for your help!!!
