Start your computer with the internet/lan connection disconnected... when the computer 1st starts up,,, click the cooresponding button to go into your bios..... if you are in bios setup and the HDD is doing that,, ten might be an issue with the windows software and not the HDD... I have a slew of Maxtor HDDS ranging from the 2 gig models to the 40 gig model in one of my PCs.. good luck....,
one more thing to consider.... Did you build the computer? chack out and make sure that the wires for the front end of the computer are connected correctly... check to see if the PWR LED is swapped with the HDD LED inadvertantly... it can happen,,, those things are poorly marked sometimes
BTW,, in the post can you decypher if it is an older ATA 30 HDD,, 60, ATA or 100?
Oh yeah btw,, I assume that Grokster is peer to peer download server software..
some of these like grokster, kazaa let you download fomr other people,,, but if there are files in that directory someone wants on the network,,, and you are connected,,, then your HDD will light up since you are now uploading to them via the software....
