Solution: Due to BIOS limitations as well as those unique to Windows, partitioning and formatting drives larger than 137 Gigabytes without proper driver or controller support will result in data loss when storing data to the drive beyond the 137 GB Barrier. In order for you system to recognize more than 137 GB you will need to utilize one of the following recommended solutions: If you have a motherboard that has a Intel chipset (810, 810E, 810E2, 815, 815, 815E, 815EP, 815P, 820, 820E, 830M, 830MP, 830MG, 840, 845, 850, or 860) please visit Intel's web site and download the Intel Application Accelerator. Intel's Application Accelerator supports the full capacity of drives larger than 137 GB. If you do not have a motherboard that has a Intel chipset then it is recommended that you purchase an Ultra ATA 133 PCI card that supports 48 bit Logical Block Addressing (LBA). You can purchase the Maxtor Ultra ATA 133 PCI Card, which supports drives that are larger than 137 GB, directly from us or your local distributor. Of course these solutions are for people who do not have windows XP SP1 or higher
This is not entirely accurate...I have Windows Xp Home SP2 and I just put a Seagate 400 gb drive in my pc. I did however have to get the latest updated accelerator for my 810 chip. This quoted post is correct, except for the last statement.
