>>Dear All:
>>
>>Back in the FoxPro for Windows days I was using a third party library called ZDRVSTAT to check the status of my diskettes when writing files to diskettes.
>>
>>It was never updated. What can I use to check disk status and handle properly the input/output problems when writing to diskette?
