Hi It's only 4 weeks since I am using MBA 64Gb and "memory is full" message appeared, then computer was frozen and I forced shut down. After this grey screen of death appeared and I can't do anything with this. Already tried: Command+R - when trying to open disc utility shows " Gathering disc data" for hours and nothing happens. Re-install OS X option - same as above. Selecting Recovery HD after pressing option key during start up - not booting. Checked the Hard drive in single user mode - shows that it's OK. Reset RAM Now trying to secureErase 1 disk 0 using Terminal.Shows "Started erase on disk 0" it's already more than 36 hours and not completed - Ithink it will not erase because it's a bootable drive? Maybe I have to use another option from Terminal? The biggest problem is that I am not ashore and have no possibility to bring my computer to service also my internet speed is very low. I will appreciate any idea how to fix this problem as I have two weeks to go and will go crazy without computer )))) Thanks in advance to everybody!!!
