Make sure that System Cache is not selected for memory usage
If you are transferring large files, the system may run out of system page table entries, which may cause the "Delayed Write Failure" error message. To prevent an increase in the number of page table entries that Windows XP must maintain and to prevent these from being exhausted, make sure that the System Cache option is not selected for memory usage. To do this, follow these steps:

1.Click Start, right-click My Computer, and then click Properties to open the System Properties dialog box.
2. Click the Advanced tab, and then under Performance, click Settings to open the Performance Options dialog box.
3. Click the Advanced tab.
4. Under Memory Usage, click to select Programs, and then click OK.
5. Click OK to close the System Properties dialog box.

If these steps worked, you are finished.
