I have these drives working in my systems. They are three Maxtors (160/8, 80/8 and an 80/2) a WD SE (80/8) and an IBM 180 GXP.
For the first 4 days of the WD SE's installation, it made this low-level grinding noise upon every initial boot up, then died away to nothing. I called WD technical and the only thing they offered was to RMA the drive. Checked it out with some software tools (IBM and WD's) and it showed OK so I kept it. Within a week, no more sounds on boot up. The Maxtor 160GB did the same thing for the first day, then it was noiseless. I thought it was something to do with the 8 M cache, but that's mere speculation and haven't read anything to support it.
Now they are all quiet even in their seek and read modes (and I've got good hearing). If you have a stethoscope or any type of tubing, you could actually place it on the drive housing itself to listen to the noise and if it still is bothering you, RMA it. I've found IBM, Maxtor and WD all pretty good about sending you another drive. Maxtor will even send you a replacement drive and you can send the RMA'd one back within 30 days with no charge to the credit card they take for this service. You may even get a brand new one if they haven't any replacements available.
Finally, I'm reluctant comments about these drives. The last time I stated that my IBM 75GXP seemed to be immune from the periodic 'clicking' failure after a year and a quarter of operation, I got the same failure. They sent me back the newly minted 180GXP.
I'm going to go out on a limb here, and state that the noises that you are hearing, if they suddenly "disappear" after a few days, and the HD seems to work fine afterwards with no recurrance of the noise, are probably due to the way that the drives are configured to operate after being shipped fresh from the factory. At least for Maxtors, they are programmed by default, for the first 10 power-on cycles, to keep write-verify enabled. Also, they (and I think WD's too), are configured to run a SMART offline scan of the entire drives surface. This scan will pause during a drive's normal use, and then resume when it is idle. It will continue to restart and run, until it completes, no matter how many times the drive is powered-down in the meantime. So basically, just leave it running for a few hours and let it finish. It shouldn't come back, unless you manually use a tool to re-enable SMART offline periodic scanning.
Also, IBM 180GXP models are known to perform some sort of diagnostic in firmware every ten minutes of drive operation, so that noise is "normal" too.
The only thing that I might be worried about, is how loud that "grinding" noise you state is. If it's not head-movement due to the internal SMART diagnostics, and is actually a real, loud, grinding noise, then you might consider RMA, although I would think that it would re-occur if there were a bearing problem. Sometimes, bearings need to "seat" for a few days, and then they will be mostly quiet for the further life of the drive motor/bearing assembly, untill they wear for a few years and start whining.
