Hard drives / IDE Channels:
i) Check the transfer rate, you need to have the transfer mode set to DMA not PIO.
Right click My Computer - Properties - Hardware - Device Manager - Expand (click the + ) IDE ATA/ATAPI controllers right click Primary Channel - Advanced Settings Tab -
If transfer Mode is PIO then follow the instructions at click here to change.
ii) Check for errors and defrag your hard drives -- My Computer - select drive - properties - tool tab - Error checking / Defragmentation.
ii) If you are using Windows XP, it's a good idea to convert your system drive to the NTFS file system if you have not already. In addition to providing numerous security and data recovery improvements over FAT32 (the file system of choice for Windows 9x/ME and XP Home) it can also speed up your system slightly.
In fact, the only real reason for sticking with the FAT32 file system for any of your data is if you have more than one operating system on your PC and the other OS's can only see FAT32 partitions (as would be the case with Windows 98, for example, which is incapable of reading NTFS data).
To convert your drives to NTFS:
Right click on 'my computer' and select 'manage'
From the computer management window, expand storage and select 'disk management.'
Using the 'file system' column of the upper pane of this window, you can easily check what file system each of your logical drives is using. Make a note of this information.
Now open a command prompt window by going to 'start\run' and typing 'cmd'
To convert a disk to NTFS, type 'convert (drive letter): /fs:ntfs'
So for example, if you were going to convert your C: drive, you would type 'Convert c: /fs:ntfs' at the prompt.
