Q: Reformatting a HD w/ 64-bit Windows 7 to 32-bit Snow L. Mac Extended

I own two 13-inch Macbooks (2006 & 2010). {And a G3 OS 9 Blue Tower}

I wish to reformat the hard drive in the 2006 machine, however the 2006 has been formatted to 64-bit Windows 7.

It was briefly utilized in a brand-x pentel-processored machine.

I tried erasing the HD in the brand-x pentel machine but it keeps a start-up reserve

for a 64-bit machine, staying in MS-DOS format. Obviously it will not work in the 2006 Macbook chasis (32-bit).

I've tried putting it in t-mode and attaching to the 2010 machine via Firewire

but I've since learned why that will not work, as a Mac OS key command will not get recognized by the MS-DOS format, OR WILL IT

with another start up command?

I'd like to reformat the 2006 so to link it to the 2010 machine via Firewire.

MacBook, Mac OS X (10.6.8), & Mac OS 9 G3 Blue Tower

TY for reading my post BUT an APPLE CSR told me a drive formatted w/ 64-bit software

will not work in 32-bit; and after trying the exact suggestion MY GINGER made onto me weeks ago...I attest the CSR's words were spot on.

[I put the drive into the 2010 machine ( the dvd-writer works on the 2010 but not in the 2006 ) with a Snow Leopard DVD,

in efforts of installing the OS or opening Disk Utility but because the drive has meta-data on it of a 64-bit nature (and of MS-DOS) nothing would initiate. I held down the C key in two attempts and the 64-bit meta-data still present on the drive wouldn't allow

anything to override it.]

In addition, 64-bit software will not default to a 32-bit OS when

32-bit peripherals are trying to jump start it; a 64-bit Microsoft Windows 7 Home Premium version.

Perhaps Microsoft Windows 7 Professional will morph from 64 to 32, I don't know for certain.

I understand Microsoft made 32-bit and 64-bit software versions separately.

    "t-mode"?? = Target Disk Mode (TDM; please define abbreviations at least once)?

     

    How to use FireWire target disk mode - http://support.apple.com/kb/HT1661 - includes description of hardware and software requirements.

     

    Target Disk Mode - Mac OS X 10.6 Help: Transferring files between two computers using FireWire - http://docs.info.apple.com/article.html?path=Mac/10.6/en/8443.html

     

    What to do if your Mac doesn't enter FireWire Target Disk Mode - http://docs.info.apple.com/article.html?artnum=75414,  also read about [Open Firmware Password Protection|http://www.apple.com/support/downloads/openfirmwarepassword.html] which can disable Target Disk Mode.

     

    My understanding is TDM is purely a function of the computer firmware and nothing to do with the drive. You can even use TDM with an unformatted drive.

    Your reply appears to be robotish.

     

    May your programmer carefully reread my posts.

     

    Your links were refreshers to unrelated ends, not a pathway to the first needed solution.

     

    The hard drive wishing to be utilized within TDM is formated as a 64-bit Windows 7, not any MAC OS format.

     

    Both Mackbooks in question, 2006 & 2010, are 32-bit.

    Do you have the  Install disk for the Macbook you want the drive to be in? If you do Then with the drive installed or in an external drive inclosure, Start up the Macbook, booting to the DVD, Then use disk utilities to erase the entire drive. That removes any m-dos on it. Then you can go ahead and use it on a partition set to one with GUID set and apply. I have yet to see a widows formatted drive that I could not wipe and set to Mac extended. If you want windows on the drive as well use bootcamp or parallels.  In Target disk using disk  utilities  it is still the same thing. My understanding of windows 7 disks is that even if the disk is 64 bit, if it's installed in a 32 bit system. It will only install as 32 bit.

    To get a handle on this, is the drive formate ExFat, Fat 32 or NTFS? I know that mac will erase NTFS And I believe Fat32. so can the drive be connected to windows and erased and set to NTFS. Then on the mac erased and set for mac extended? A couple of years ago I changed a drive on a macbook 32 bit with a window formatted drive. Did not pay attention to the formate. I erased and installed mac os externded. So I'm  having a hard time understanding the question.
