Window XP Home Upgrade

By dennis.vandeventer ·
I have windows98 and want to upgrade to XP home with the NTFS file format. I have read that there is a problem with upgrading because you end up with 512 byte clusters with FAT32 conversion to NTFS instead of the 4K clusters you would get if you bought a machine with XP HOME already installed. Is there an easy way to go from Windows 98 to Windows XP home and end up with NTFS and 4K clusters? I read that the 512 clusters were ineffecient and would slow the machinge down.

Window XP Home Upgrade

Cluster size is a compromize between disk speed, and wasted space.
However, the main negative of small cluster sizes is that the file table is larger, and it takes more time to query the file table for the location of the data you are trying to retrieve.

For a given disk size, NTSF will have smaller clusters than FAT32.

The larger your clusters, the larger a file that will fit in a single cluster, and a (VERY) slightly faster file transfer.
The negative is, that a 1 byte file now consumes the full cluster size.
For smaller clusters, you tend to better utilize the disk space, but may have more clusters per file.

In your example of cluster size, a 4K file would take up either 1 (4k) or 8 (512b) clusters.
However, 8 small files of say 256 bytes each, would take up 8 clusters either way.
With the 512 Byte clusters, you would use 4K of disk space for 2K of files.
With 4k clusters, the same 2K of files would use up 16K of your disk space.

Unless you have a very small hard drive, your clusters may already be 4K or 8K. I suspect that the FAT to NTSF utility keeps your cluster sizes the same as they are.
(Otherwise, it has a lot more work to do to preserve your files.)

One reason that new PCs have 4K clusters with XP, is that the drives are so big.

The bottom line is that you will not see a major performance difference from smaller cluster sizes.

You can convert a ntfs cluster size with partion magic to any size (aslong it a leggal one) you want.
