I'm unable to install onto an SD Card:

$ ./image-usb-stick ../GNOME_3.x86_64-0.0.3-Build1.1.iso 
Loading disks...
No devices found.

The problem is that the OsxDisk.is_valid() check is too stringent and rejects the SD Card.

Disk Utility information for the SD Card:

What kernel are you using for this image?

I'm using your tool to write some SUSE Studio generated .raw files.
The only issue i can see is the the progress/percentage indicator is full after less than 1 minute and i suppose it shows only the time elapsed for formatting the USB stick.

Selected: USB_Flash_Disk (/dev/sdc) - 4 GB

WARNING: imaging /dev/sdc may result in data loss! Continue? [Y/N]: Y
100% 0:00:39 [================================================] ETA 0:00:00

Suggest you tweak the script to use /dev/rdisk# instead of /dev/disk# as rdisk is MUCH faster when using dd. dd a 700mb to /dev/rdisk1 (with bs=1m) image takes about a minute, but with /dev/disk1 it takes a good 15 minutes.

Cheers.

We have a request to package this in Homebrew: Homebrew/legacy-homebrew#14018

Would it be possible to tag a stable version? Doesn't need to be "1.0" or anything, just any version number so we get a "real tarball".

If not, let me know, so I can pass on the request until this software is considered stable. Thanks.

Hi, I found a syntax error in your source code

image-usb-stick|262 col 13 error| Missing parentheses in call to 'print'`

I tried to use the program to write to my USB stick using OSX 10.5, but the program reported No devices Found.

I resolved the issue by changing some of the tests on the diskutil output
read_only_media is called read_only:
Read Only: No

The media size has the unit B instead of Bytes:
Total Size: 1002.2 Mi (1050934784 B) (2052607 512-byte blocks)
