GH2 MTS file copy, error (mac code -36)

I copied a file from my SD card to my harddrive. It was a group of over 200 files so I didn't check every file all the way through, but... after formatting the card, I am having trouble with the file. It will start to play in VLC, but then crash a few seconds into the video. The file won't even allow me to copy it to another drive (gives me the error code -36 saying that it can't be read or written). My question is, is it possible to salvage this file? I tried opening it in Premiere pro to see how it would handle it, but it just freezes premiere. Any help would be great?

and on a random note are GH2 files best logged and transferred or edited directly in premiere or final cut (i use both) Thanks.

From Apple:
Type -36 error (I/O Errors (bummers)
This file is having difficulty while either reading from the drive or writing to the drive. The file
may have been improperly written data to the drive or the hard drive or disk may be damaged.
This is almost always indicative of a media error (hard error on the disk). Sometimes (rarely) it is transient.
Solutions: Try copying the file to another drive. Use a disk recovery software, such as Disk First Aid to examine the disk. You can try rebooting with all extensions off. Once in a while this will allow you to read the data. The file in question should be restored from a backup that was stored on a different disk. Regular backups can reduce the time to recover from this error.

In your case you have erased the original file so that won't help. It looks to me as you are hosed on that one.

If you are using FCP, I would (and do) transcode and then backup the SD card to another drive and only then format. That way you always have a way out. Also dutring transcoding, if there is an error on the card you'll find out then and not later.
 
The best way, of course, is to immediately make a(n extra) backup of all files you copy to your hard drive.
If you make a backup of the local copy, you will already notice if all the files can be read, and if so, chances you get an error on the same file on two sources are small(er than for one file only).
 
Hello,

What you need to do is to generate a copy of the file with I/O errors. Then the file may be playable (thanks to MTS being a transport stream) except on areas with I/O errors. Or maybe you need to repair the video file after copy.

The process to copy a file with I/O error is based on "dd" command.
For detailled instructions, see this blog post:

I hope that this helps you.

Regards,
Benoît
