Inconsistent read/wrtie speed on my HDD?

post #1 of 3
Thread Starter 
I don't know what happen but one day my hdd started to run slow then usual.

I noticed this when it took more time to load battlefield 3 maps and low fps on the game play videos I recorded.

I did a bit of search and people heard about windows changing my hdd to PIO mode from DMA but on device manager

ATA channel 0 & 1 are both DMA enabled...

Any idea what is wrong??

my hdd:



Device manager:

436

Screen shot of bench mark:

460

Looks like other software is accessing the drive. I suspect if you went into safemode and ran that test again, you'd get a more pristine graph.

PIO mode is slow. It hammers your CPU and makes everything super laggy. I mean to the point where clicking the start menu takes 5 minutes. If you get locked to PIO mode rather than DMA, removing the ATA channels from the device manager and rebooting is the kind of thing that you do while watching a TV show. tongue.gif (it takes that long)


How full is your drive? The end of the drive is slower than the start (the edge), so as you fill it the drive performs worse. Because of that I usually partition my drives in 2, putting the more important data in the first partition.

Hmm... have you checked your drive's health? When was the last time you ran a Defrag? Grab Defraggler and check the Health tab - then post a screenshot for us.

If the drive is healthy, then maybe a defrag will help? The Windows defrag misses a lot.
