I want to remove OS X from a drive to use it only for storage, I have tried to move the system to the trash but keep runnung into permission problmes.

 

How do I get the operating system off the drive?  I cannot erase the 1T drive because it holds all of my iTunes music and videos with 50 gigs remaining. I do not want to purchase another drive just to reformat this drive,

 

I do not want to use the drive as a boot up drive.

 

Why is it so hard to delete the system? 

 

Why am I getting so many "You do not have suffecient permissions?"

 

Thanks for any help

    Hi, personally I'd want a second bootable drive for safety.

     

    In Finder do a Get Info on that drive, what rights does it show?

    Hello  BDAqua and thanks for your help!

     

    I have additional hard drives installed with bootable systems. 

     

    The drive in question has been giving me problems. I chose the entire hard drive and selected applied to enclosed items after that, the system seemed corrupt.  I think the only solution is to reformat and start over.

     

    Question: I used Time Machine to back up the "working" startup drive THEN for the screwed up hard drive  I only chose my user account which of course has the iTunes folder along with 880 GB of music, television shows, and movies that I do not want to lose.

     

    Now, after Time Machine has finished I should be able to reformat the drive, go into Time Machine and retrieve my user folder to be reinstalled on the freshly reinitiated drive.

     

    Does that sound right?

    In Theory that should work, but I found earlier versions of TM quite quirky/unreliable when it came time to Restore things.

     

    I'd want a 3rd backup of those 880GB for sure.

    I chose the entire hard drive and selected applied to enclosed items after that, the system seemed corrupt.

    Have you tried Disk Utility's Repair Permissions on that drive?

    I tried Disk Utilities  From an external FireWire drive, the system install disk and the internal 500 Gig  drive.  Each time disk utilities would calculate 15 to 18 hours to complete the process. I let it run all night   and when I checked in the morning it froze the system.

     

    The system works great on the external FireWire drive and internal 500 Gig  until I tried to use them to repair the 1 TB drive that's giving me trouble.  Both drives ended up with permission errors which disk utilities was able to fix.

     

    I also tried DiskWarrior to repair disk permissions a couple of times and it froze each time.

     

    I tried to do an archive and install.  Its a weird thing because it would not install.  I kept getting the message "the installation failed try installing again"

     

    Oh and…   the "troubled" drive will be my third backup.  I am trying to install it on a different computer which Is capable of streaming to Apple TV. I had it working before with the 1 TB drive as the startup disk.  Now, everything is all screwed up.

    Sounds like that drive might be failing.

    Well, the disc is about three years old.  Today I guess that's 160 years old for a hard disk… I don't know.

     

    It is one of those green Western Digital drives that I took out of a USB enclosure. Once I installed it in my Mac it worked fine, then crashed. I could not get it to format again. I took the drive out and for about six months it sat in a drawer. Then I read an article about Western Digital drives SATA versus eATA… Maybe you're familiar with it.

     

    In any case, once I put the proper jumper on the drive worked like a pro so I did a fresh install of OS X and it never gave me any trouble again until I tried to remove the OS. So I'm a little hopeful.

     

    Time Machine was able to back up my user folder ONLY, now I'm going to reformat the drive and see if I can put my user folder back on the drive.

     

    This is way too much work… But what are you going to do?

    OK, keep us posted please.

    First of all, I hope I'm not the only one that  has three 1 TB drives with less than two years of service sitting in a drawer. I don't think it's a mechanical failure on any of the drives, the two Western Digital drives were taken out of the USB case. The Seagate drive was put into an aftermarket case And connected to the wrong powered  adapter.

     

    Well… Things seem to be getting worse. I should have known not to trust this Western Digital drive as it has been giving me trouble from the first time I liberated it from its USB enclosure. At first it did not work at all, after slowing it down from ATA 300  ATA 150 using the proper jumper it was working brilliantly.

     

    Now, the drive is inconsistent at best. However, there are extenuating circumstances. For one, the drive is installed in my G4 MDD computer via the Sonnet's Tempo™ Serial ATA PCI adapter card.  These MDD Macs weren't exactly known for being great at plug-and-play.

     

    Now… I booted from the system installation DVD and in the last effort  I am doing  one more reformatting attempt. The first two attempts failed after I reformatted the drive. When I  tried to use the drive it would vanish from the desktop.   Disc utilities is useless. I used it to repair the drive and it reported the drive was fine.

     

    I have heard… Though have not confirmed… That zeroing out a hard drive will help eliminate bad blocks and can cure some mechanical problems. Keep in mind, this drive is only it about two years old and has never been used. I couldn't take it back because I had ripped it out of the USB enclosure they came in.

     

    Too much information right?

    Yes, it is possible, how likely can't say, or of it does fix it, how long it could go after that.
