I cannot understand why I am unable to reinstall my Mac OS X installation disk 1 after performing a 7 pass erase. I kept the installation disk in the computer because iMac would not allow me to eject it. Plus I needed the installation disk in my computer to perform the erase in Disk Utility. did I erase the entire installation disk?

iMac, Mac OS X (10.6.8)
I want to start afresh on my HD, i.e. reinstall from original disks and use Disk Utility to secure erase (via Erase & Install).I've read articles about pros and cons + how to do it. So I think I know how to do everything.However, from my reading I gather that Zero Erase is a single pass random erase whereas 7 Pass is secure erase (and there is a 3 Pass secure erase option nowadays)?That got me wondering - does 7 Pass secure erase make 7 x single passes over the entire disk?If it does, then when the blue bar has extended a bit over a third of the way across the progress monitor (that little bar that indicates time left) it should have made 3 passes, which would be equivalent to 3 pass secure erase?Is that an option?Is it possible to stop part way through an erase (which is part of E & I)? My original disks 1 and 2 have OS X 10.4, with OS X 10.5 included as complimentary 3rd disk (because OS X 10.5 was just released at that time).I gather I need to erase with disk 1, then install disks 1 + 2, then install OS X 10.5.

Haven't heard back from Seagate to see if my drive and firmware is bad, but since I just bought the drive, I'm thinking of returning it.I'm in the middle of a 7 Pass Secure erase on it (1TB). Do people feel comfortable returning a drive after doing that erase? Or should I just forget about it and destroy the drive and chalk it up to a loss?

I have a 2007 Blackbook with Snow Leopard installed. I tried to install Bootcamp but it said that I had to do an erase + reinstall first. I booted my mac up from the OS X disc, got past the language menu, then got a pop up stating "MAC OS X Cannot Be Installed." I can't click on Disk Utility or anything else on the menu bar. How else can I erase my HD?

I recently did a complete erase of my hard drive and re-installed Mavericks. I chose to start clean rather than use any Time Machine back-ups. I used the same external hard drive for my new Time Machine back-ups. Now I cannot open any back-ups/items prior to the re-install via Time Machine. They are listed along the right hand sidebar in Time Machine (star wars view) but will not open when clicked on.Â
Some files I can access if I go to the actual backup folder - ex a Pages doc BUT ff I try to open the iPhoto library from the back-up folders stored on the external drive, I get the following error message -
I cannot open the iPhoto "package" to access individual photos from these back-ups.Â
So - how can I get Time Machine to allow access to the pre-install back-ups??Â

I have a mid-2007 20" iMac, 250 GB hard drive, 4 GB memory, and it runs Lion.I understand I will have to reboot the computer with Snow Leopard, since Lion is non-transferrable, but do I do this after I've deauthorized iTunes and done a 35-pass wipe of the hard drive?Also, do you recommend that I add biogradable peanuts to the inside of the box (I have the original) before shipping it, or are the Apple-provided styrofoam bumpers that fit on each corner sufficient? It's going USPS to a military base overseas.

I have a file that suddenly appeared and it says that it can not be deleted. I dragged it to the trash and the exact message is:
The item "7702D020" can't be moved to the Trash because it can't be deleted. Â Â
I tried unlocking it. It does nothing when I try to find the info. It says that it is an Excel file and I can not open it either. I am afraid that it is a "nasty" type file. Malware or something along those lines. Â

I thought I could use a 1TB External drive to back up my 320GB startup disk, and use the rest of the empty 680GB for storage. However, Time Machine started taking up 600GB of spaceon the External drive! I was like "What the heck!?" So I put unwanted Time Machine Backups in the trash and emptied it. Nothing, they're stuck there now.Â
I'm planning on wiping the disk clean and starting over, but for future reference is there a proper way to delete Time Machine Backups? Surely there must be; (I mean, who would have known Time Machine would take up MORE SPACE than the drive it's backing up in the first place?

I have my external HDD partitioned for my Media storage and for Time Machine. Unfortunately, my mac is having problems and I want to back up my computer to reinstall Lion. Problem is...Time Machine is also not backing up anymore (last backup was 2 months ago). So I want to erase the Time Machine volume of my HDD so I can use SuperDuper to backup my hard drive...but of course I don't want to erase the media partion. Â So...using Disk Utility, I can just erase the Time Machine partion (volume) of the HDD and leave the Media portion intact, correct? I would hate to erase the Time Machine volume and find out the Disk Utility also erased all my music and movies too!
