Readyboost problems(Windows Vista)

When I resume from standby, the HD access is blinking, and when I check the "Reliability and performance monitor" it says its writing stuff to the readyboost file on my Memorystick duo(Lexar1gb, 940mb sharing)

Edit: This really enoiys me because the HD drains the battery for like 1min, and then I standby it it again in like 10 mins(going from class to class, and having pauses in lessons)

 

bump.......

 

i venture to say that this is not a problem with readyboost but one of its constraint. We can look at readyboost as an extra "ram" area (thus volatile) for vista performance swap. So when u go into standyby mode, all cached data must be written to REAL disk, or lose it. Readyboost ("ram") lost everything that it caches in standby mode. Waking up, it must try to re-cache everything.

I m sure that eventually that this would be fixed since a delay in re.writing cache after standby does not make any sense, comparing when system first starts up with readyboost.

my 2 cents -

doesnt stand-by(now called sleep) leave the ram powered on? and why would there be a data loss on a memory stick duo? It doesnt lose the data when I remove it from a psp, why should it lose data when the pc goes to standby? Also, I heard that readyboost is supposed to speed up boot times, but the card reader acces button doesnt blink until after about a minute in windows.

Edit: I just measured it, and it writes to the card for more like 2-3 minutes, until it copies about 400mb of data to it

 

powered on yes, but data caching - no.

normally all data would be written into disk on prior to standby (pagefile mechanism)

u r not losing data, u r just losing ur cache

readyboost is not meant to speed up boot time. Only when ur system is running, making more efficient. Vista uses it as a short.stop.gap instead of using the disk pagefile

it depends on how many apps were open before standby and in what state they were in. Again it is only a performance.working.cache - think about it as a very fast pagefile/swap area

ok, so how can I stop it from accesing it when I resume from sleep?

 

i m not quite sure, insides services, almost all entries now have "automatic-delayed" option, readyboost has it as well. But i m not sure that this would apply to "delayed" after resuming from sleep

the simple way is just to unplug the flash.drive before leaving ur system, and pliug it back in after coming back from stand.by; "sometimes" (i have not been able to get my readyboost device to work 100% of the time when un.plug & then plug it back in) vista would recognise that it is already being used for readyboost and just go o; and not asking u what do u want to do with the device.

u can always check the properties of the flash drive (controller) and UN.check (if applicable) "shutdown device for power management" or something in the same description. -This would at least, stop the os in turnign off the device for saving power when in stand.by or not in use

the best solution would be for m$ to take a closer look at readyboost in stand.by and hibernation in vista.
