FTP Server Large File Data Corruption

I'm using CodeWarrior 10.6 with MQX 4.2.

 

The problem I’m having is this:

 

  1. I have the MQX Micro SD driver, Ethernet and FTP Server running on the K70 tower kit.
  2. Using Windows Explorer as an FTP Client, I can successfully FTP files to and from the Micro SD card.
  3. When FTPing a large file (162 MB) from the Micro SD card to my PC, the transfer completes and the file size is exactly correct.
  4. However, when I compare the FTPed file to the original file, there are from 2 to 4 16-byte blocks that are incorrect.  The number and location of these “bad data blocks” vary from one transfer to the next.  All other bytes are correct.

 

I've tried other FTP Clients and other Micro SD cards, with the same results.

 

Has anyone else seen this problem?  Any ideas on how to troubleshoot would be welcome.
