Oh shoot, you got me, LOL... I guess the correct spelling is "disc"...I had a disc (or is is disk?) I had some vacation pics on in a stack.
From: http://www.wsu.edu:8080/~brians/errors/disc.html“Compact disc” is spelled with a “C” because that’s how its inventors decided it should be rendered; but a computer hard disk is spelled with a “K” In modern technological contexts, “disks” usually reproduce data magnetically, while “discs” (CD-ROMs, DVDs, etc.) reproduce it “optically,” with lasers.
