Installed Snow Leopard
Installed Snow Leopard and Toshiba Canvio External hard drive March 3013 in my 2007 iMac. Three days ago - Nov. 2, 2015 the icon for the External Hard Disk disappeared from my desk top. No idea why. Checked utility disc-nothing. Can't use Time Machine. Don't know how to locate the disk. Checked wires-all secure. Any advice would be appreciated - everyone needs backup. Thanks
iMac, Mac OS X (10.6.8)
