Poblems in installing Hitachi 180G???

Recently I bought a Hitachi 180G hard drive and installed it as a slave drive (data drive).

BIOS correctly recoginzes the capacity(180G, actually 185G).
However, when I use "Disk Management" in windows 2000 professional to partition the new HD, the tool only recognizes 128G. How could I get the extra 60G back?

Thank you!

Well as for the 185gb, hitachi and it's predecessor that it bought the HDD technology from ibm had came up with a scheme adding extra space to their hard disk drives for whatever reason.
Maybe to only allow ibm's to be put on a raid, not really sure as the size isn't significantly larger.
I've got two ibm hard disk drives and they are 123.5GB rather than 120Gb.
However you your drive has GB's based on base 10 rather than base 2. All hard drives are like this, not sure on the reasoning for this, for mathmatical reasoning computer to be running off of base 2, however HDD's are base 10 giving you 172.05GB total, so that is your total ammount. As in base 2, a kilo is 1024, and in base 10 it is 1000.
To figure your hard disk drive space lost in the conversion use this example:
(HDD Space) * 0.93 = (total GB's recognized by your computer)

185GB * 0.93 = 172.05GB

However what this problem your having seems to be a limmit with your hardware, please post your specs, also for your motherboard or pci controller etc, whatever you use to hook up the hard disk drive, you will need to find a bios update, hopefully your hard ware is new enough to support above 127gb limmit.
Also update your copy of windows 2000 if it isn't at service pack 4 already and your motherboard drivers/pci controller, whichever you use.

Please keep in mind to post specs with your hardware questions, makes it much easier to answer questions and it's a general rule of them as it is quite relavent information with a problem like this as it is the hardware that isn't recognizing over the 127GB limmit.

Thank you for your informative reply.

I have solved the problem. Now it is shown as 172~3GB in windows 2000 after formating.
