Hard Disk Limited to 8-GB Partition
This article was previously published under Q153550
When you try to partition a drive that is larger than 8 gigabytes (GB) in
size, the maximum partition size may be 8 GB.
This behavior can occur if the hard disk controller does not fully support
the interrupt 13 extensions. This information applies to both IDE and SCSI
hard disk drives.
Contact the drive controller's manufacturer for information about a
possible BIOS upgrade to a version of the BIOS that fully supports
interrupt 13 extensions.
In order for a hard disk that is larger than 8 GB and uses the FAT32 file
system to be fully addressed, it must support interrupt 13 extensions.
Io.sys tests for the presence of interrupt 13 extensions. If interrupt 13
extensions are not detected, the default CHS LBA limit of 7.9 GB is used.
To determine whether your BIOS supports interrupt 13 extensions, please
refer to your computer's documentation or consult your computer's
manufacturer.
APPLIES TO
- Microsoft Windows Millennium Edition
- Microsoft Windows 98 Second Edition
- Microsoft Windows 98 Standard Edition
- Microsoft Windows 95

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
