Win disktodisk copy=100% CPU usage?

By rbower ·
Is it normal for the CPU usage to stay around 100% during a disk to disk copy of files using Windows 2000? Is there any way to speed up file transfer from one hard disk to another (besides replacing the existing drives with 10,000 RPM SATA or SCSI drives)?

1. Need to find out what process is running besides disk-to-disk copy. Close all programs. Open Task Manager (Ctrl+Shift+Esc) and click on Process tab an then click on CPU to sort by CPU usage. Proceed to copy files such that you can see the task manager at the same time. Observe what process(es) is consuming the CPU. Once you found it, either disable or uninstall it.

2. It could be HW that might be the cause. Uninstall all devices (PCI, zip, CD-ROM). If this resolved the problem, install one at a time to find the culprit.

3. If you still have the problem, one of the HDs may be failing. Do a HD diagnostic test.

If a process other than copying files (explorer.exe) is consuming most of the CPU usage, you need to identify what it is. If it is one of Windows system processes, it may not be removed or disabled. Please add a comment if there is such a process.

While the above is correct it also depend upon what is being copied at the time you said Disk to Disk coping so it sounds like some sort of Backup and if there is a lot of Data to transfer and in big chunks it could be quite normal depending upon the system.

Like if I copy 14 ISO images from a SATA drive to a 15K SCSI while the transfer is running I will see 100% CPU usage on a Dual Processor M'Board with Built in SCSI. But if it is a 20 K file I usually don't see much of a increase in CPU usage. So while you need to find out what processes are running in the background you also need to look at what is being copied. If they are big files or lots of small files 100% CPU usage is quite acceptable while the transfer is occurring.

Disk to disk copying should improve if disks are on separate IDE channels.

7200 RPM UDMA drives are fairly fast if configured correctly.
