Here us some info copied from the Maxtor site regarding the 32 MB hard drive limitation.  Jumper settings are shown at <http://service.maxtor.com/rightnow/images/maxtor_quantum%20jumpers.htm>

> If the operating system, BIOS, or MaxBlast can only recognize 32 GB 
> of the drive it may be caused by one of the following:
> 
>    1. Drive Jumpers: Applies to Mac and Window users. On drives that 
> are larger than 32 GB there is a Capacity Limitation Jumper (CLJ) or 
> the Alternate Capacity (AC) Jumper setting. This jumper will limit 
> the capacity of the drive to 32 GB and should only be used when the 
> BIOS hangs when trying to auto-detect the drive. If you have two 
> jumpers shunts on the drive you will need to remove the CLJ or AC 
> jumper. To resolve the issue use the standard jumper settings.
> 
>       If you format the drive with the CLJ or AC jumper then the 
> drive capacity will be limited to 32GB. After removing the CLJ or AC 
> jumper the drive will still be recognized as 32GB. You must reformat 
> the drive without the CLJ or AC jumper to gain the full capacity of 
> the drive.
> 
>       For more information on Windows XP/2000 installs and the 
> Cylinder Limitation jumper please reference Answer ID: 1374
> 
>    2. BIOS: On older systems (pre- November 1998) the BIOS may not 
> support drives that are larger than 32 GB. In the BIOS setup please 
> set the drive type to AUTO detect. If the BIOS detects the full 
> capacity of the drive then the BIOS will support the capacity of the 
> drive. If not please perform one of the following:
> 
>          1. Check with the system or motherboard manufacturer for any 
> BIOS upgrades for the system.
> 
>          2. If a BIOS update is not available from the manufacturer 
> you can also visit the following site: www.esupport.com and download 
> the BIOS Agent to determine if an update is available for purchase 
> for your system. The BIOS Agent will identify the BIOS on your system 
> and provide you with all of the information that you will need for 
> ordering a BIOS update. Maxtor® Corporation provides this information 
> as a courtesy to its customers and has no official affiliation with 
> esupport.com.
> 
>          3. (Recommended) Purchase a PCI ATA controller card that 
> will support the capacity of the drive. The two benefits of ATA 
> controller cards are:
>                1. The ability to support large capacity drives
>                2. The ability to support the faster transfer rates of 
> the drive.
> 
>          4. The last option would be to use our MaxBlast software. 
> The MaxBlast software will install an overlay (EZ-BIOS) on the hard 
> drive to support the full capacity of the drive.
> 
>    3. Operating System: Windows XP and 2000 have a 32 GB format 
> limitation for FAT 32. That means if you formatted the drive in FAT 
> 32 with Windows XP and 2000, the largest partition supported is 32 
> GB. You will need to format the drive in NTFS if you want to 
> partition the drive larger than 32 GB.
