USB drives include USB flash drives (sometimes known as "memory sticks") and USB hard drives.

The Sugar Manual and Activity-help.svg has more information and graphics to help you.

How to install and mount

Insert the USB drive in one of three USB ports on the side of the display of the laptop. The SD card inserts into a slot under the display.

Accessing the USB drive

Go to the Journal, which you can access from the Home View. Select the notebook icon just below the XO character to open the Journal.

The USB icon Usbkey.png appears in the lower left corner of the display.

Copying a file from the Journal to the USB drive

To copy a file from the Journal to the USB drive, move the cursor over the Journal item and drag it to the USB icon.

Copying a file from the USB drive to the Journal

To copy a file from the USB drive to the XO, click on the USB icon itself (rather than the number or text above the word "Unmount"), then drag the item from the USB drive to the journal icon.

Removing the USB drive

To remove the USB drive, mouse over the USB icon itself and click on the word "Unmount". When the USB icon disappears, it is safe to remove the USB drive.

USB drives and firmware

The XO's firmware can access a USB drive during boot, for example to upgrade system software or write a new image. For the flash drive to be compatible with firmware, make sure that your USB flash drive is formatted as FAT or FAT32, and only contains one partition. Most ordinary USB flash drives are set up this way, except "U3" flash drives which won't work. Remove U3 with uninstall software from http://www.u3.com/uninstall

Other USB Flash Drives *Confirmed* Incompatible with XO's as of Dec 20, 2008:

  • Kingston DataTraveler (1GB). These all-black USB flash drives were purchased by OLPC late Nov 2008, and none of them work when reflashing 656 to 767. Mitch Bradley says:

The bug (<trac>5354</trac>) was fixed in firmware Q2D08 (and in all subsequent firmware versions), but unfortunately, the firmware that was included in build 656 (also known as "Ship.2" and release 7.1.2 is Q2D07. The best solution is to update to later firmware. Upgrading the XO to a newer release will install newer firmware, or see Upgrading firmware to only update the firmware.

But note that the Kingston DataTraveler 1G device also has problems under Linux during the initramfs stage, see [3] .

For advanced users

The USB drive's filesystem is automatically mounted under /media based on the drive's disk label, for example /media/KINGSTON/ You can use Linux commands such as df in the Terminal activity to access its files. For example cp tmp/* /media/My_drives_name

How to Damage a FLASH Storage Device is a detailed page telling you how to degrade the performance and reliability of FLASH-based storage devices like SD cards and USB keys (pendrive, etc). And by implication, how not to damage them.

  • Secure Digital card - the XO-1 also has a slot for an SD/SDHC memory card, which you can access from the Journal and Terminal in a similar manner.
