Have exactly the same problem. Are you using 1.0.1 ? . I was and when I rebuilt the sketch for 0022 the problem went away !. I have no problems uploading to the other boards I have with 1.0.1 only the Mega 2560. Could it possibly be the software ?.

Can you test http://arduino.cc/forum/index.php/topic,118440.0.html ? I upgraded the 'uploader' in that modded version. I had a similar problem (frequently) with 1.0.1 and my 2560 but Samueldw's arduino never worked.

Just tried that and it still will not upload to a Mega 2560. No problem with a Uno or a Uno Pro. I have just rebuilt the Mega program so it does not use any 1.0.1. parts so I can upload with the old 0022. Do like that SRAM estimate though after getting caught out on one sketch.
Many thanks

Samueldw,

I noticed in your earlier post that you had mentioned the use of the 8u2 chip and I am pretty sure the 2560 is using the 16u2.  May help may not but anyway it is generally good to know.  Also, I have not found any good information on resetting the 16u2.  I believe mine (16u2) is bricked but haven't completely thrown in the towel yet, whats more I have not been able to determine the reason why it is no longer working.  I must admit that locating complete information on the 2560 is a bit like tracking down "Big Foot" in a snow storm...occasionally you can find a foot print but "Big Foot" always seems to get away...:)

I had the same problem and also went back to 0022.
I feel fine with 022, it works great and I will not upgrade.  ;)
