Formatting your shiny new external hard drive

About a year ago I purchased a MacBook Pro.  I had been following Apple for some time, as a casual observer, but with the announcement of Intel chips and the ability to run Vista (and mac os X, redhat, ubuntu, etc.) on a mac really encouraged me to take the leap.  I probably fall into that category of power user, as I tend to max out my peripherials, external usb hubs to connect all my gear, external displays, and most recently a firewire external hard drive.

Now I’ve had several external hard drives in the past, but had always had to format them differently so they played nicely between vista/mac OS, often keeping some NTFS (windows), some fat32 (both) or the default Mac OS Extended (journaled) – but this time I wanted one drive to rule all others – fat32! If you didn’t already know, fat32 can be read (and written to) by both MacOS  & Vista, so you can utilize the drive (with some minor limitations) under either OS!  Great for centralizing your media, mp3’s, pics, etc – as they typically don’t exceed the 4GB limitation.

Couple of things to note, fat32 does have limitations.  First, it has a size limitation on the files you store on the drive, 4GB.  Also, if you try to format with winXP or Vista, it barks if you try to create a partition larger than 32GB.  We’ll discuss work-arounds below.

Quickly, if you are trying to format fat32 on winXP and Vista, you’ve probably noticed the GUI only lets you format with NTFS.  So how can you do it (knowing the limitations above)?  Easy: Go to ‘run’ from the start buttona nd type ‘cmd’ to bring up the command prompt.  Next, type: format (drive letter): /fs:fat32 – and off you go.

Now, if you moved along too quickly (as i did) you’ll get a “The volume is too big for fat32” error message – this is windows thing, grandfathered back from when the Indians used to format hard drives and there were known issues with drives > 32GB.  Technically speaking, the fat32 format should theoretically support up to 2TB!  Anyhow, here’s how you can work around this:

*Below outlines how to do this in Windows, if you prefer Mac, this can be done easily using the Disk Utility.  Note:  This has worked well for me in the past using external USB drives, however my firewire drive, while formatting fine on the mac side, was not recognized on Windows, and required me to re-format (below.)

Here’s the *Windows* workaround, you need to get yourself a drive letter so you can access the partition.  Open control panel / administrative tools / computer managment / and locate teh Disk Management (under Storage) – you should see a black bar with the disk # and status of the drive.  Right click and choose Mark Partition as active.  Then right click again and choose change drive letter, set it to your desired letter.  If you want help with this step, here’s a guide: http://support.microsoft.com/?kbid=309000

Next, you’re ready to format, download a copy of fat32format. Extract the single EXE file to somewhere suitable, like C:\. Click Start->Run and enter cmd. CD to the where you extracted the fat32format exe, e.g. by typing CD /D c:\

Now, type this (if using Vista, make sure you’re running command prompt as administrator)

    fat32format f: (or whatever your drive letter is)

You should see this displayed

    Warning ALL data on drive 'f' will be lost irretrievably, are you sure (y/n)

Now when it says this, it really means it. If you format the boot sector, FATs and root directory will be filled with zeros. By pressing Y and hitting return, whatever was on the disk before will be wiped clean.

Assuming you don’t bail out at this point you should see something like this (rather quickly) –

    Warning ALL data on drive 'f' will be lost irretrievably, are you sure
    (y/n) :y
    Size : 250GB 488392002 sectors
    512 Bytes Per Sector, Cluster size 32768 bytes
    Volume ID is 1bdb:2c1d

    Wrote 61083648 bytes in 0.988463 seconds, 61796609.106193 bytes/sec
    Initialising reserved sectors and FATs...

That should do it!  If you want to confirm the results, type: chkdsk f:


Where are the new MacBook Pros?

I’m in the market for a new laptop, and have been following Macs closely since they began sporting Intel processors.  My Toshiba Tecra/tablet is in need of an upgrade, while it still works nicely for casual use, I tend to push the envelope a bit, mult-tasking and running several development IDEs.  I puchased the laptop back in late 2005, pre-Vista; even with a faster hard-drive and more Ram, she still falls a bit short for my needs.  I’d really love to see a quad-core cpu in the new MacBook Pros, like the announcement recently made for the Mac Pro (G5’s) with dual, quad cores!

From what I gather, the MacBook Pro is ripe for makeover, latest rumors predict an LED screen in the 17″ models, multi-touch (as found in the new macBook air) and penryn processors.  Last release of the macBook pro dates back to June of 2007.

I fully expect to begin using the new Mac OS (v10.5 Leopard) for typical desktop tasks, but am still tied to Vista due to Visual Studio.  I also plan to install Ubantu, for a triple boot power-house.  If only Apple would annouce the availability of the new macBook Pros!!
