22 Formatting the Hard Drive
Using a Drive Larger than 137 GB
To properly access the full capacity of a drive larger than 137 GB, you 
must install one of the solutions described below. Using a drive that 
has been formatted past the 137 GB barrier on a system without an 
installed 137 GB solution can result in data loss.
Ultra ATA/133 PCI Card Solutions
If your Maxtor hard drive came bundled with an Ultra ATA/133-
compatible PCI card (such as the Maxtor Ultra ATA/133 PCI Card or 
Maxtor SATA/150 PCI Card), or you have an installed Ultra ATA/133 
PCI card, you can safely use your drive with the card on Windows 
98SE, Me, 2000, and XP. Note that ATA/100, 66, and 33 PCI cards do 
not support drives larger than 137 GB unless specifically noted by the 
manufacturer. Some system BIOSes do not support booting to drives 
attached to an ATA card, so you may only be able to use this drive as 
additional storage and not as the boot drive.
If your are interested in adding an Ultra ATA/133 card to your system, 
the Maxtor Ultra ATA/133 PCI Card and Maxtor SATA/150 PCI Card are 
fully compatible with all Maxtor ATA drive capacities. These Ultra ATA/
133-compatible products are available from www.maxstore.com or 
from your local computer retailer.
Operating System Solutions
The Windows operating systems that natively support the full capacity 
of drives larger than 137 GB are:
• Windows XP Home, Service Pack 1 (SP1) and higher
Windows 98/Me Note: Some tools 
built into Windows 98/ME, such as 
Scandisk and Defrag, do not function 
properly on hard drive partitions larger 
than 137 GB. Third-party utilities such 
as Norton Utilities 2002 can be used 
to replace the functionality of 
Scandisk and Defrag for partitions 
larger than 137 GB.
Macintosh Note: Most Mac systems 
require a Mac-compatible Ultra ATA/
133 PCI card (not included) to access 
the full capacity of a drive larger than 
137 GB. Mac-compatible ATA/133 
cards are available from Sonnet 
(www.sonnettech.com), Miglia 
(www.miglia.com), and ACARD 
(www.acard.com).
