Microsoft has responded to the hidden feature following the Xbox 360′s Spring Dashboard Update.
The hidden feature, Maintain Storage Devices, is used to clear the HDD cache, but should only be used as recommended by Xbox 360 tech support.
From Microsoft: “The HDD cache clearing feature is a part of the Xbox 360 technical support process and is only supported in those instances. While the cache clearing operation will not harm or render your console inoperable, it should only be used when instructed by the Microsoft customer support staff. As always, any gamers experiencing issues with their console should contact 800-4-MYXBOX instead of attempting to troubleshoot on their own via this feature.”
