    I downloaded Paragon as someone told me on the forum. Now I can both r/w the external HD. I tried to use the same HD as my time machine, but it doesn't show up in the "select backup disk" list.

    Does anyone what the problem is? Do I need to format it to FAT?

    Time Machine requires the drive to be formatted as journaled HFS+.

    Thanks! Does it compatible/readable with Windows XP/7?

    Ugh...Is it only read-only in Windows?

    HFS+ is not readable/writable in Windows without third-party software. A Time Machine volume is not intended to be used as a "generic" data storage volume; it's only for Time Machine.

    The only way is with a windows program called MacDrive.

    I try to format my old HD for time machine by Disk Utility. Should I choose "GUID Partition Table" in the option?

    A little clarification on formatting options:


    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X.
      [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
      [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended)
    • Read/Write HFS+ from native Mac OS X
    • Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
      [*]To Read/Write HFS+ from Windows, Install MacDrive
      [*]To Read HFS+ (but not Write) from Windows, Install HFSExplorer
    • Maximum file size: 8EiB
    • Maximum volume size: 8EiB
    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB

    ugh...my old HD is too old. It's even too small to backup a 2-week old Mac.
