This is from Maxtor's site: I guess its not necessarily 120gigs, but it looks like 137.
[/i]Due to limitations in Windows and many types of system BIOS, partitioning and formatting drives larger than 137 Gigabytes without proper driver or controller support WILL CAUSE DATA LOSS when storing data to the drive beyond the 137 GB Barrier.
In order for you system to recognize more than a 137 GB perform one of the following recommended solutions:
1. 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
www.intel.com/support/chipsets/iaa/ and download the Intel Application Accelerator. Intel's Application Accelerator supports the full capacity of drives larger than 137 GB.
2. If you do not have a motherboard that has a Intel chipset then it is recommended to purchase a Ultra ATA 133 PCI card that supports 48 bit Logical Block Addressing (LBA). You can purchase the Maxtor Ultra ATA 133 PCI Card at
www.maxtordirect.com which supports drives that are larger than 137 GB.
If you did not follow one of the above steps and you are trying to go by other means of "tweaking" the system to recognize the drive past 137 GB please note, if your ATA controller, chipset drivers and/or system BIOS do not properly support 48-bit Logical Block Addressing, DATA LOSS WILL OCCUR when storing data to the drive beyond the 137 GB barrier.[/i]
