So, if there's a 20 & 40GB model, then it's the 40GB model they tested. Okay... In any case, having an extra head in the drive isn't going to matter at all. they've already got a platter or two inside, and that's pretty much the only spinning part in there that'll cause the motor to run hard and generate heat. Also, the temperatures will remain pretty much the same across the same model line I suspect due to the similarities in all other parts. Okay.. then it's likely that the Hitachi DK23FB-40 08K1472 with 1 platter and 2 heads is likely to have pretty much the same specs as the DK23FB-40 07N9482 with 2 platters and 4 heads, si? Then my next ponderment would be... why should Hitachi go from the 1 platter and 2 head model to the 2 platter and 4 head model, if not for increasing performance? Wouldn't having twice the surface area for the same amount of storage, say 40GB, and 4 heads instead of 2, enable the 2 platter/4 head model to read and write a bit faster? In any case, you may want to just try out a HD and see if it goes. Buy from a place with a return policy, or simply drop it into an external case (eg. those coolmax cases at pccmicrostore/shop.com I noted earlier with those aluminum external 2.5" cases). Anyways, a lot of us are happy . Hey, there you go! Poll time!! Who's running what inside their Librettos just fine? L110 with 20GB Hitachi here - no problems for 2+ years. Heh... Well, my L50 w/??? HDD hasn't had any problems at all recently... but then the poor forlorn thing has been sitting on the shelf, not given much attention as of late. L70 is still my main work horse with the noisey Fujitsu 20GB that MP3s start clicking on after 5-10 minutes or so. But I did just install Win98SE a while back, and I really doon't know if I've checked that clicking since. I do want to get one of those high fidelity Layla PCMCIA sound playback cards for about $100 at some point. Anyone familiar with those? The L100 needs clocking back from 266 to 233, and W2K installed instead of WinXP I think. The Toshiba 6GB HDD in it has never had any problems. Where's that bargain on a L110 to complete my collection?? ;-P Matt _ Instant message during games with MSN Messenger 6.0.

Date: Fri, 26 Sep 2003 07:50:01 + From: "Matt Hanson" <[EMAIL PROTECTED]> Subject: Re: Hitachi 5200 overheat L70? Interesting specs David. I pasted the data you sent together in a pseudo table format to make things easier for me. The specs for the Travelstar 80GN/4200 and Toshiba MK8025GAS/4200 are pretty impressive compared to their 5200RPM counterparts. But it's really frustrating when I go right to the spec sheets from the manufacturers, and find that there are 2-3 models that are sub-classes of each model. Which drives are which among the specs you forwarded me isn't clear. Though the differences between sub-class models are not that great I guess. The article Tom pointed to comparing the Toshiba MK4019GAX and Travelstar 40GNX were enlightening, and from there finding a 40GB model in the Travelstar 40GNX line lead to that Hitachi DK23FB series that has got my attention for their energy efficiency and performance. I'll try calling the companies selling them tomorrow, and see if I can find out a bit more about the series.
