slow dvd data transfer rate on m115-s3094

Hi,

I noticed that all of a sudden my dvd drive (it is a dvd burner) on this laptop is transferring data (read) at only half the normal speed. I suspected it might be forced into quiet mode always by the acoustic silencer software. I changed the settings to both "normal mode" and "quiet mode" and there was no difference in the data read rate.

Any idea what the problem could be. What else can i tweak. I noticed this problem immediately after installing norton utilities. I have since uninstalled norton and it is still slower than before.

Thanks,
-Raj

 

Look at the IDE channels in Device Manager, IDE ATA/ATAPI controllers and see if one channel has a current transfer mode of PIO. If so, uninstall the channel then go to the top of the device list and select Detect hardware changes. This should reinstall the channel as UDMA-2.

The interface can drop into PIO mode if there are multiple timeout errors due to reading problems.

Thank u very much for the suggestion. That worked out great! I suspect that the crappy norton utilities slowed things down to a crawl making the system think there are IO problems and so downgraded this channel to PIO.
