    Problem for creating ReadyBoost on a RAMDisk


    I want to create a ReadyBoost on a RAMDisk (manually) in Windows Vista, for this I did the following things
    - Set the registry value for this device at the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt\"Corresponding device Name" as
    -- CacheSizeInMB = 0x0000010e (270)
    -- CacheStatus = 0x00000001 (1)
    -- DeviceStatus = 0x00000002 (2)
    -- DoRetestDevice = 0x00000000 (0)
    -- HasSlowRegions = 0x00000000 (0)
    -- LastTestedTime = 0x00000000 (0)
    -- PhysicalDeviceSizeMB = 0x0000017f (383)
    -- ReadSpeedKBs = 0x3b9aca00 ( 1000000000 )
    -- RecommendedCacheSizeMB = 0x0000010e (270)
    -- USBVersion = 0x00020000 (131072)
    -- WriteSpeedKBs = 0x3b9aca00 ( 1000000000 )

    - Restart the "ReadyBoost" service

    The RAMDrive has not configured as ReadyBoost and the "readyboost.sfcache" has not created on the RAMDrive; If I right click on the RAMDrive and configure it as ReadyBoost from properties then it works properly; the "readyboost.sfcache" file has been created on the drive also and the registry value has been set as above. One more thing, The same procedure I have followed for a USB Flash drive and it can be configured as ReadyBoost by both way.

    NB: To make a ReadyBoost on RAMDisk, the RAMDisk type must be USBDrive Type.

    Could anybody please tell me how can I solve the problem?

    Thanks in advance,

    In this situation you should create "ReadyBoost.sfcache" file manually with the same security attributes of original one.

    That's all
