I am very nervous. Short story. Apple sent me a replacement MacBook after many problems with old one. It has had constant kernel panics. So they finally agreed to replace it. I was going to back up the MacBook now to a USB drive I bought once I organized the system like I wanted it. Well, no time for that now. I picked it up and it started making a loud, loud clicking sound that struck fear into my heart. I shut it off. And I realize the only thing to do is to start backing up now. I turned it back on, connected the USB drive, downloaded superduper, and I am backing up now. I hear it making that sound and I am sitting terrified the sound will stop meaning the disk can no longer spin. I have about 200 GB used up on the disk so it's gonna take a long time to back up over USB 2. I just hope the MacBook lasts that long. Does anyone know how long it takes a drive to fail usually after the clicking sound starts? I have never had a drive failure before. I have very bad OCD and am terrified of losing things ,and I have been thinking the last few days about data loss. I seriously have been. And I still was too stupid to back up because I wanted to keep organizing my system first. I have one of those FreeAgent bus powered drives that's probably gonna be super slow too! I kept thinking it was too good and too lucky that Apple is replacing this wit the new 2.4 GHZ aluminum MacBook and even upgrading to 4 gb of ram for me. I thought I was petty complaining about the kernel panics. And now this! It makes me feel like I was right in thinking it was too good to be true, that nothing is for free. I promise to always do automated back ups from now on. I swear. I'll give to charity, just let me keep my data!
