Hi. First time here - please be gentle. I am working on iMac 24``, Snow Leopard. Recently used my flash USB stick, then ejected it and unplugged, but ever since every time I restart the machine the feral USB disk shows up again, like a ghost. Re-named it to "Damn". Funniest part is, that I can erase it, format it and such using the Disk Utility! No disk, but still operational. Can even store data on the non-existent drive! When I eject it it still shows the faded icon in Disk Utility and it`s even poss to mount it again! The port us being used by another device, which works all fine. Reset PRAM as a first line of defense - no result. Please help. Thanks!
