Corrupted MTS (AVCHD) videos - Please Help

[RenatoZoppei]

Guys, I´m begging for help here. I have a SONY HDR-CX405 with a Samsung SD Card on it. I recorded something like 40 videos with it and the last half of it is corrupted and I can´t reproduce (even on the camera). I really donát know what to do but, believe me, it´s REALLY important. Any ideas?
P.S. I´m really new to this, if you guys could help me like you are talking to a child, I appreciate it.

Can you copy the files to your computer?

[RenatoZoppei]

Here is a file for example.

Using a card reader, copy the contents of the card to your PC as a backup.

Sometimes files get messed up because the camera was turned off too quickly or the battery died. Put the card back in the camera and turn the camera on. It may repair automatically. Try to copy your files to computer using the camera's USB.

There is a file repair utility accessible through the camera's menu system. Try that too.

I did it and the camera really offered me an option to repair anything. It says now that I have only 44,9 Gb free from 62,4 Gb total, but only show me 7 images and 1 video in the camera but currupted.
Do you think that I can do anything on the files that are on the computer? Is there hope?

Looking at the file you uploaded in a hex reader -- it's all zeros. There is nothing there to recover, sad to say.

Wow, that´s terrible. But, I´m very, very grateful that you took your time to help me. Thank You very much.

Wow, that´s terrible.

I couldn't agree more and feel your loss having been there myself. Seems like we have taken a step back from the glory days of analog tape when things just seemed to work without any hassle, and even if something went wrong, you could just splice out the offending part of the tape and be back on your merry way.

I have the same problem, and I re inserted the card in the camera and used the repair utility, all it did was it produced a backup file and copied every thing into it but the corrupted files where not repaired, they where just copied into the backup as they were.
