An unknown disk on my desktop

A while ago, I installed a backup of SL onto an SD card. Ever since then, a disk named "DISKOS3" appears on my desktop and the SD card isn't in the SD card slot. Its icon is the same as Macintosh HD. There is nothing on the disk and it says that there is 6.17GB available. It isn't hurting anything but I was curious if there was a way to delete it. I can eject it but every time I boot up, it is back. It isn't hurting anything, I just want it gone.

Sorry if this is in the wrong category, I didn't know where to post it.

15'' MacBook Pro (Mid-2009), Mac OS X (10.6.3), 2.53GHz Core 2 Duo, 4GB 1066MHz DDR3, GeForce 9400M 256MB

Never mind. I just found out how to fix it on another forum. All I had to do was go to Disk Utility, and under partition remove DISKOS3.

Okay. First select the volume that you want to erase. Then go to the partitions tab. You should see a box that is named "Volume Scheme". In that box, click the partition that you want to delete. Be careful not to choose your main partition (Macintosh HD), as doing this would clear all of the data from you hard drive. The blue shading in the box shows the amount of data on that partition, so select the one without the shading. Then click the minus button under that box and it should remove it.

Again, be careful not to select the partition with all of your data on it.
