Hi All,

I do not need to think about the performance issues, I just wanna
implement it for some academic project purpose. So could you please tell
me why the ReadyBoost does not work after configuring it manually that I
described above(Please take a look at the 1st posted message).

Thanks
Imran

Quite frankly, you are so far away from the "intended purpose" that it's
most unlikely you'll find anyone who can help.

As we've said, Vista isn't designed to work that way. I can only suggest
you take this up with Microsoft, although I'd be surprised if they've even
tested the scenario you describe.

I've been trying to find out how to implement a ram drive in Vista. It
appears that your registry entries will do so.

I want to use the ram drive as a place to save files that I will only use in
the current session, like unzipping files. Can you tell me what entries I
would use to set up, say, a 512kb ram drive. Nothing fancy, just suitable
for saving files to.


Thanks to anyone who has suggestions or answers,
Danno

I want to create a ReadyBoost on a RAMDisk (manually) in Windows Vista
Ultimate 0x32 bit, 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,
Imran

In my view, except for a very rare very special situation, it's
invariably a very bad thing to do. It reduces the amount of RAM
available to Windows, and can adversely affect your performance--in
many cases, very seriously.


It
appears that your registry entries will do so.

There's no need to do that. If you are concerned about keeping those
temporary files, just create a folder on the hard drive to save them
in; then write a batch file to delete the contents of that folder, and
put a shortcut to that batch file in your Startup folder.

The above will accomplish the same thing without hurting your
performance.

But Ken, having a ram drive is so kewl!

You're probably right. Under 98 & 2000 I use to make a lot of use of batch
files. Just not used to thinking of them in Vista.

I'm going to use one as you suggest. Just for my edification, why does the
performance take such a hit? I've got 2MB ram and never go over 75% usage.


Thanks much for the help,
Danno

Most people don't have more RAM than they need, and if they use some
of it for a RAM drive, there is less RAM for Windows.

If you have more RAM than you can use, then, of course, a ram drive
doesn't hurt you. But that's very unusual.


Thanks much for the help,

You're welcome. Glad to help.
