    Hello,

    I have a new external drive (Lacie little big disk) that is in RAID0 mode and has only one partition. I already moved several important files to it including Aperture library.

    I am wondering if when I set it up as backup disk for Time Machine, if that will erase the files on there now?

    Thank you.

    It will not, as TM backs up into one folder with lots of subfolders, thus it will work to use that HDD as backup disk for TM.

    PS: Do you backup the LaCie disk regularly to another HDD?

    I just want to make sure I understand you correctly. I'm looking at this sub link from the link you sent:

    http://web.me.com/pondini/Time_Machine/6.html

    It says that certain conditions have to be met if I don't want the data to be erased. I don't see either GUID not Apple Partition Map when I follow the directions. At the bottom of the Disk Utility panel, it only says

    Disk Description: Apple RAID
    Set Name "LaCie"
    Type: Striped RAID Set
    Version: AppleRAID version 2.0

    Are these the proper prerequisites for using it as a Time machine backup without erasing data?

    To answer your question, yes, I plan to keep regular backups of the entire LaCie drive. Are you asking because they suck?

    sorry for hijacking but i was about to start a similar thread

    i currently have a 500GB drive in my MBP and i have an external 500GB harddrive i do Time Machine backups too

    im thinking about getting a 1TB internal and a 1TB external, how would i go about transfering my old backups from the old external to the new one?

    is it as simple as pluging both externals into the MBP and copy the contents on the old one to the new one?
