Re: All Large (~3GB+) Files Download Corrupt

It's hard to imagine a failure mode that would only impact large files. But a failure that doesn't happen very often would be more likely to hit large files. Have any smaller downloads also been corrupt?

It might be interesting to do a binary comparison of good and bad versions of one of these files. Also, a comparison of two bad downloads of the same file would tell you if the same error happened on each download.

You mentioned a friend with FIOS service. Could you borrow his router for testing?

If there's bad memory in the router, I would expect it to cause checksum errors. Packet sniffing might detect excessive retransmissions. The checksum is only 16 bits, so corruption that preserves the checksum is possible.
