Yes. Change the default partition table to GUID using Disk Utility, and format the card to use the Mac OS Extended file format to do so.

yeah, but a tiny 16 or 32 gig SD card would make a great emergency disk.

I loaded a SD card in my camera, formatted it and took 500 pictures.

Any way to get the bootable OS I had on it back ?

This topic comes up from time to time on the mydellmini forums & I've always wondered why anyone would want to boot from a SD card.

PC's have been able to boot from SD cards for a couple of years. It is much more than a great trouble shooting feature now that 16 GB cards are fairly cheap. Which would you rather use to install or diagnose problems the OS with Linux/Microsoft/Apple: a 150x SD card (5 ms access time) or from a 20x DVD drive (100 ms access time)? You could have three (or more) SD cards, each with a different OS.

Yes, with BIOS support or the magic potion:

Is there an easier way?

Big deal. I booted my 2400c into OS 8 from a Compact Flash card in a PCMCIA adapter at the turn of the century.

The final desktop icon appeared last Tuesday.grinning smiley

Is booting from as SD card slower than booting from a DVD?






I am that Masked Man.

All you can do, is all you can do.

There’s trouble — it's time to play the sound of my people.

Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

I've been to the edge of the map, and there be monsters.

We are a government of laws, not men.

Everybody counts or nobody counts.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

We don’t do focus groups. They just ensure that you don’t offend anyone, and produce bland inoffensive products. —Sir Jonathan Ive

An armed society is a polite society.
And hope is a lousy defense.

You make me pull, I'll put you down.

I *love* SIGs. It's Glocks I hate.

Rats! Per that kbase article, the SD card slots in the new Apple portables will not support SDIO cards. Those are mostly used by old Palm / Windows Mobile devices to hang peripherals off us such as WiFi adapters, Bluetooth adapters, analog modem cards, barcode scanners, and so on. That might have been a nifty way to add an eSATA or an extra Firewire port.

Then again, anyone remember the Eye-Fi cards? Those are not technically SDIO cards, but regular SD cards with built-in firmware that manages WiFi connectivity with the device you install it in (e.g. a digital camera). So I'm wondering if something similar would be possible for wired connections like the aforementioned eSATA and Firewire. One can only hope...

Nah, that is pretty much SDIO.

The eye-fi is a vanilla memory card to most devices. the wireless functionality is disappointedly restrictive.
