|Summary||Windows does not recognize the full capacity of a large hard drive|
|Details||If you install a hard drive larger than 128GB, Windows 2000 or XP may show the disk as 128GB instead of the actual capacity. This affects only IDE/ATA hard drives.|
|Cause||There are two primary causes of this issue:
In short, Windows or your computer's BIOS does not support Big LBA (logical block addressing) mode.
|Workaround||Use the drive as it is seen by the system. You will lose access to the extra space.
Purchase an external drive enclosure or similar device and make the drive an external drive.
In addition, using an additional ATA controller may be an option, as detailed below.
The solution may be a combination of the possible solutions below, depending on our system configuration.
