Ubuntu - Error: Failed to create the SD card

I see a lot of posts about writing to the SD card, but I believe my problem is different. I am unable to create the SD card during the process of building an AVD. I initially tried to use the Android SDK and AVD Manager to do this, selecting <br>**Name**: my_avd <br>**Target**: Android 2.2 - API Level 8 <br>**SD Card**: Size: 1024 MiB <br>**Skin**: Built-In: Default (HVGA) <br>**Hardware**: Property: Abstracted LCD Density, Value: 160 This pops up a window with the message: <br>"Result of creating AVD 'my_avd': <br>Error: Failed to create the SD card." I tried to repeat the process from the command line, receiving a similar error: alex@alex-desktop:~$ android create avd -n my_avd -t 1 -c 1024M Android 2.2 is a basic Android platform. Do you wish to create a custom hardware profile [no]no Error: Failed to create the SD card. Attempting to follow instructions for using mksdcard was equally unproductive; I think my basic lack of linux experience may be causing me a problem here. When I try to use mksdcard, it just reports that it cannot find the file or directory. Is the mksdcard tool available for use this way in linux? alex@alex-desktop:~$ mksdcard 1024M ./sdcard.iso bash: /home/alex/android-sdk-linux_x86/tools/mksdcard: No such file or directory alex@alex-desktop:~$ sudo android create avd -n my_avd -t 1 -c 1024M I've added the android tools directory to my PATH variable, but I feel like there is obviously something else I'm missing. Perhaps some kind of access rights? Attempting to run the android command with sudo did not seem to help either: alex@alex-desktop:~/android-sdk-linux_x86/tools$ sudo ./android create avd -n my_avd -t 1 -c 1024M Android 2.2 is a basic Android platform. Do you wish to create a custom hardware profile [no]no Error: Failed to create the SD card. I even tried installing Eclipse and the ADT plugin and running the manager from there to no avail. Any tips would be most appreciated. Advanced warning that I am somewhat of a novice Linux user, so even if it seems like a no-brainer obvious thing to check, I could still have missed it.
