My 1TB HDD has been formatted in my Windows 2000 Server and it now shows only 128GB in Computer Management but shows the full 1TB in BIOS and i have searched and can't quite get a clear answer as to why it will not show the full data amount.

Delete all the partitions and re-initalize. If that doesn't work you may have a defective drive.

check to see if the drive has a size limit jumper on it. some older sata and ide drives use to have a jumper to limit the size so people could use newer drive in older pc.

It appears that your OS version may be affected by a 28-bit LBA limit.

48-Bit LBA Support for ATAPI Disk Drives in Windows 2000:

"Windows 2000 Service Pack 2 (SP2) and earlier versions of Windows 2000 do not support 48-bit Logical Block Addressing (LBA) as defined in the ATA/ATAPI 6.0 specification."

"To resolve this problem, obtain the latest service pack for Windows 2000."
