Hola Amigos, la Imac que tengo me marco este error al encenderla por la mañana buscando por el internet encontre la siguiente solucion:

Try Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior


El problema es que extravie el OS Tiger 10.4 quisiera saber si se puede descargar de algun lado. O si al meter el numero de serie de mi mac permita que descargue dicho software.

saludos.
