There are two 60GB HDDs and one 250GB HDD for XBOX360. Initialized. There is writing on the back of the HDD in the top photo. In the third photo, the text on the bottom 250GB HDD was not visible due to reflection, so it was taken separately. Operation confirmed on an actual XBOX360. Some XBOX360 HDDs have an emulator that allows you to run old XBOX software on the 360, while others do not. I do not currently own any old XBOX software, so I cannot confirm. I remember that the 60GB ones had it, but I'm not sure. Please be aware if you intend to use old XBOX software on the XBOX360. These have been used for a long time, so the HDDs themselves may be degraded, and are therefore considered junk. As these are used items, please refrain from purchasing if you are concerned about scratches or other damage.
