Something does not seem correct. There is a 4GB per partition limit if the hard drive is formatted with the old style FAT type format, and a 4GB per file limit if the hard drive is formatted with a FAT32 type format. If the hard drive is formatted with a NTFS type format, the maximum data file size is limited by the maximum number of blocks permitted by Oracle, about 4 million blocks, and if the database is using an 8KB block size, that limits the maximum data file size to about 32GB on Oracle when running on Windows 2003:

A search of Metalink does not find that patch number, but an advanced search does find bug 2585700 which is apparently fixed in Oracle and in So, it appears that your friend needs a Metalink account to download the or a more recent patch set.
