hi all
i am using a sandisk 32gb sdhc card for my camera.
i recorded some video and i wanted to move it to my mbp but i get a error code-36 message
i then tried to copy the clip using win7 and i got aa error there too

i think it may be damaged but i am able to watch the clip directly from the sd card and it works perfectly fine so i am not sure where the damage or corruption is.

the file is a .mts file
all other pictures and videos copied over to my mbp just fine.
i tried rebooting, using another computer and that file just wont copy.
i checked the permissions on the file and nothing wrong there.

so am i dealing with a bad file or what?
can i somehow use some software to fix the file to allow me to copy it over to my mbp?
 
What filesystem is on the card and what is the size of the file?

filesystem is MS-DOS FAT32 it was formatted on the camera.
the camera is a Lumix LX5 with a .MTS extension and a size of 3.78GB i have other files with larger sizes that transfered just fine.
 
Can you copy any of the file? Like does it start and then fail part way through? Just use ddrescue on linux, maybe osx too?, or something like jfilerecovery on windows to copy the file. They won't give up on read errors and copy as much of the file as possible. A small amount of corruption in a video file can won't necessary be the end of the world.

FAT32 is not supposed to support files > 4GB. If you have files larger than that perhaps they are using exFat on the camera.

Once they get over 4gb they are split
When the file is being copied it stops at about 2.7gb and gives me an error-36 on mac
On win it copied about 3.1gb and it just froze

Can I run ddrescue from Ubuntu on just that one file?
 
i ran ddrescue on the 32gb sdhc card and it made a .img file now what am i supposed to do with it?
i loaded ubuntu 11.10 onto virtualbox to use ddrescue
 
Think you can run it on just the file, but if you have a dd image you can mount it like a drive w/loop:
mount -t fat32 -o loop file.img /mnt/ddimage
 
I think it should be vfat instead of fat32 in the mount. Although I do not use that much.
 
i got this error

and i forgot to create log when i started can i generate it after i stopped ddrescue?

mount: wrong fs type, bad option, bad superblock on /dev/loop1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

ok ddrescue finished but i mounted the img file and there are just jpg files no mts files
can i try and run ddrescue on just that one mts file?
how could i do that?
 
... something seems wrong. But yeah you can run ddrescue on just the file.

Plug in usb key and mount it, or by default Ubuntu should mount it to like /media/sdcard or something.... just do 'ddrescue /media/sdscard/something.mts /home/whateverusername/something.mts'
