USB2.0 External HDD

I purchased a Western Digital 40 GB, 5400RPM USB2.0 external HDD(2.5") recently and when I try to copy large cunk of data, windows gives me an error

“Windows-Delayed Write Failed”
Windows was unable to save all the data for the file \Device\HarddiskVolume6. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file else where.

But small chunks of data can be saved. Also when this happens, windows does not recognize the partitions of the usb drive and shows only one letter for the drive without any contents!

My PC’s configuration is as follows:
850MHz Celeron
256MB SDRAM
Internal 20GB Samsung HDD(54000RPM)
PCI-to-USB - PCI card fitted into PCI slot(Has 4 USB outlets)
Windows 2000 Professional with SP4

I have no conflicts whatsoever with the USB drivers.

One more thing; I have not faced the above problem when I try to transfer data from another system which is of a higher configuration than what I have mentioned above.
This system’s configuration is:
Windows 2000 Professional Service Pack 4 (build 2195)
1.93 gigahertz Intel Pentium 4
8 kilobyte primary memory cache
256 kilobyte secondary memory cache
512MB DDR-RAM

Any fix?

This really isn’t my field but just to throw the idea out in the open maybe it’s possible you’re computer has USB 1.1 ports while your drive has a USB 2.0 connection. While USB 2.0 is backwards compatable maybe larger chunks of data don’t appreciate the low bandwidth of 1.1 while small files can cope?
