1.) Windows 2000 can't recognize a hard drive larger than 137GB natively. In order to get Windows to recognize larger drives you need at least SP3. Have you installed the latest service packs?
2.) Depending on your current BIOS version, you may need an update in order for your computer to correctly recognize the full 250GB. During boot a BIOS screen should flash...press the designated key to enter BIOS/setup, and write down what version you have...that will aid in the search for an upgrade, if one's available.
3.) You can click here for a registry tweak to resolve the issue of Windows not recognizing 138GB+ drives. Just be careful when modifying the registry.
4.) Partitioning your hard drive into a couple of chunks should solve the problem as well. It's up to you how you'd like to do this.
Hope this helps,
I am running Windows 2000 on an older machine....I installed a 250gb hard drive but the computer only recognizes 1/2 (125 gb)...Can I remove the drive to another computer and recover the rest of the drive? Would it be possible to then return it to the older computer and read the who;e drive. I believe the problem is an older bios only recognizes smaller drives.Would it be a workaround I partition it outside of this environment?
Thank you for your help!
