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,

Re: Problem for creating ReadyBoost on a RAMDisk
In this situation you should create "ReadyBoost.sfcache" file manually with the same security attributes of original one.
