just stop the antivirus in the task manager and check cpu usage is same as 96% if at all the same change antivirus or format your system this may give full solution

Hi - Thanks for the reply. The AV was off for the performance tests. Dell has a series of software updates that aren't easy to find, called Notebook System Software. Look through the "Applies to" entries till you find your notebook model. The updated drivers solved my problem!

I suspect that the original problem was that Windows had dropped from DMA mode (fast) to PIO mode (slow) after recording an excessive number of CRC errors. If so, then expect this to happen again.

In fact the minimum transfer rate of 1.1MBps would suggest that the drive still has problems. Moreover, it is reporting 60 reallocated (ie bad) sectors which means that it does indeed have media probems.

The reason that a firmware update resulted in a temporary fix is probably because the updated drive appeared like a replacement, in which case Windows reverted to the DMA default.

Hi fzabkar; I'm sure HD Tune 2.55 (freebie) doesn't tell the whole story, but it reported UDMA Mode 5, Supported and Active, both before and after the driver updates. Should I infer from your message that the program is not to be trusted? I had the dvd.reset app at the ready, but I didn't use it when HD Tune didn't report PIO.

I agree that the media probably has problems, but the owner of the notebook is pleased with its performance. I interpreted your message to mean that further problems can be expected and I passed that alert on to him.

Thank you for your thoughts on this problematic drive.
