Last fall I purchased a new Haitachi HTC426030G7AT00 drive for a salvage Thinkpad X41 tablet I had aquired. However, I soon discovered the notorious continuous "click-THUNK" noise of the drive parking it's heads while idle (confirmed by SMART load/unload count). By that point the drive was out of the seller's return period, so thus I went to the task of researching the issue. The noise does not seem to indicate a mechanical issue; it is believed to be over-aggressive power management. In the end, no firmware/driver updates to the X41 or drive itself, nor the hdparm -255 or -254 commands, had any effect on the noise. As far as the hdd firmware updates go, I tried several different versions and alterations to the configuration files but the update always failed. I suspect the reason for the failure is that the drive I have differs in some small way from the drives the X41 was originally configured with.

My brother is now in need of a tablet pc and so I am trying once again to fix the drive issue. I will attempt to retrace my troubleshooting attempts to post additional info here soon (and hopefully find some critical bit I overlooked). In the meantime, any thoughts or info from this community would be greatly appreciated. Thanks!

I recommend running a brief scan with MHDD. Can find this for free on the software area of hddguru.com.

I suspect the scan will run in a bunch of Xs in the form of UNC or other errors. Once you see a lot of these, it is time to move on to a new drive.
