readyboost not work with SD card ?

Can anyone tell me why my Sandisk 1gb SD card not work with Readyboost yet if I plug in a 512mb Sandisk SD card it works fine. What gives?? Anyone else having issues working with sandisk SD cards and ready boost. I tried formating the 1gb with NTFS and FAt and still no dice. The 512mb card was FAT and works.

 

Hmm... I use a 2GB SanDisk SD card with ReadyBoost and it works fine... so it shouldn't be the size at fault. Try reformatting as FAT32, then going into properties --> ReadyBoost tab. If it says the device isn't fast enough, click retest, then WAIT. It will look like it already completed the test and that the device failed immediately, but really the test lasts 45-60 seconds, then suddenly the device will pass and you can choose to use it for ReadyBoost.

Let me know if it still doesn't work.

 

Nope that didn't work. I formated fat32 and let it test card extra long and nothing happened still says "device does not have required performance". Odd.

 

Some slower USB flash drives and SD cards are not Vista compatable. Maybe the 512mb SD card is faster than the 1GB one, and that's the reason it works.

 

It does sound like you just got a slow card... or a bad card. If it's new, I'd exchange it at the store as defective. It would be the first SanDisk brand card that I've seen not work.

 

is there some software I can use to test the speed of this card so then I can compare it to what the speed should be for this card?
The card seems to format ok and I can load data on it. I mean if a 2gb card works for yuou shouldn't a 1gb card work too?

 

Well, the commandline utilities to perform the ReadyBoost test with scores posted are:

winsat disk –read –ran –ransize 4096 –drive D
and
winsat disk –write –ran –ransize 524288 –drive D

In both cases the end D is the drive letter of your SD card or USB device. These commands also need to be run from an administrative command prompt.

You can also run event viewer by typing "Eventvwr.msc" into a run prompt. Then go to Applications and Services Logs --> Microsoft --> Windows --> ReadyBoost -->Operational to see all of the ReadyBoost logs, including speed test results.

Of course, neither will actually get you up and running with ReadyBoost. They'll just provide the results of a test. You're really better off just rerunning the test till it passes. I've seen devices pass on the 6th or so retest. If a device hasn't passed by the 8th or 10th try, then its time to give up.

 

Some cards will not work if they don't meet the speed requirements. The likelihood of a 512MB card being 'faster' than a 2GB one is very high, so it isn't surprising to me that the 2GB one isn't being accepted.

 

I think he said that his Sandisk 2gb works fine, yet my Sandisk 1gb does not work.

 

Whatever the matter is, the point is that you need to meet a speed requirement, dictated by the ReadyBoost test program in Vista. If you do not meet the specs, ReadyBoost is a no-go.

 

I am using a SanDisc 2Gb card with no problem. There must be something wrong with the one you are trying to use. Is it an older model?

 

I don't know. I'm going to just try to exchange it for another one back at the store.

 

I just tried the SanDisk Ultra II 2.0GB and it did not pass the test. I ran the command line test and it showed the read speed at 1.38 MB and write speed of 0.48 MB.....what a joke.

I guess this thing is going back, but I'm not sure which one to try now.

 

oh no, i have the same 1GB from SanDisk but its flash drive, maybe it doesnt work as well..
