Windows 98 Microsoft patches

Windows 98 and Windows 98 SE patches are not available on Microsoft Windows Update server any more.

So I collect here some useful ones:

Windows 98 Fdisk Update

Release Date: March, 23 2000

This addresses an issue on Windows 98 and Windows 98 Second Edition computers when using Fdisk.exe to partition a hard disk that is larger than 64 GB (64 gigabytes, or 68,719,476,736 bytes) in size. Fdisk does not report the correct size of the hard disk.

Fdisk uses some 16-bit values internally to calculate the size of the drive. Some of these variables overflow when the drive size is equal to or larger than 64 GB.

The size that Fdisk reports is the full size of the hard disk minus 64 GB. For example, if the physical drive is 70.3 GB (75,484,122,112 bytes) in size, Fdisk reports the drive as being 6.3 GB (6,764,579,840 bytes) in size.

Windows 98 Large IDE Update

Release Date: March, 10 2000

This update addresses an issue on Windows 98 and Windows 98 Second Edition computers that have an integrated device electronics (IDE) hard disk that is larger than 32 gigabytes (GB) in size. If you use the protected-mode (graphical) version of ScanDisk to perform a thorough scan (which includes a surface scan) on an IDE hard disk that is larger than 32 GB, ScanDisk may report errors on every cluster after approximately cluster number 967,393.

This problem may occur on computers that use a Phoenix BIOS and use the Phoenix BitShift translation algorithm to report the geometry of large IDE hard disks.

Windows 98 Second Edition IDE Hard Drive Cache Package

Release Date: September, 20 2000

The Windows IDE Hard Drive Cache Package provides a workaround to a recently identified issue with computers that have the combination of Integrated Drive Electronics (IDE) hard disk drives with large caches and newer/faster processors. Computers with this combination may risk losing data if the hard disk shuts down before it can preserve the data in its cache.

During the shutdown process, the contents of the virtual cache are written to the destination device. If the destination device is an Integrated Drive Electronics (IDE) hard disk, data may be written to the hard disk’s onboard cache but not to the disk itself. When this occurs, the data is lost from the cache when the computer turns off.
