Upgrading my Harddrive

[furiousmonkey]

Using a T21, I have seen a Hitachi 80GB Internal 2.5" Laptop Hard Disk 7200RPM for sale and was wondering, what I am looking for in the way of physical size and of course compatilbility with my laptop?

Thanks

As long as it is a 9.5mm thick and 2.5" PATA hard drive with less than 160GB, it should work.

Personally, I would stay away from Seagate drives in a Thinkpad...as much I like them in desktops, there have been some reported issues with the firmware.

In 2004 I upgraded the original 20GB 4200RPM HDD (Hitachi) in my T21 with a Hitachi Travelstar 5K100 60GB 5400RPM HDD, model # HTS541060G9AT00. It worked fine. This month, I will be upgrading it again with a Hitachi Travelstar 7K100 80GB 7200RPM HDD, model # HTS721080G9AT00. In 2004, price was the issue, which is why I only went with at 5400RPM drive. I paid $30 less this year for the 7200RPM (8MB cache) drive than I did for the 5400RPM drive 3 years ago.

The 60GB drive will be going into an Adaptec USB external enclosure and be used as a backup drive.

Along with CPU & memory upgrades, I'm trying to get some extra life out of my 6 year old T21.
