Corrupt memory cards?

[Roland200]

I was wondering if anyone could help me with the following problem.

I have just got back from India after two weeks of photography. Before I left I bought two new 8GB x133 Transcend CF cards from Amazon. I got back and downloaded them using Nikon Transfer and started to process the Raw files.

This is where the problem occurs with these two cards, about 65% of the files fail to open for processing even though the thumbnails are present. In Nikon capture it just says 'error processing' and will not open. In LR3 it says 'There is an error working with photo' then 'An unexpected end-of-file occurred'. In Photoshop it just comes up as an error.

The strange thing is that the other 35% open as normal and can be processed.

I also took my San Disc cards and everything was as normal with no issues.

The photos all can be viewed on the camera and in windows photo viewer and be run as a slide show. I just can't process them and convert to Jpeg for printing and it is really frustrating after spending so much time and effort taking them.

Any help or advice would be greatly appreciated.

Did you copy them using a card reader or via usb with the camera? The latter seems to be more reliable. Lots of people seem to be having trouble with transcend cards lately so I am beginning to think they're a brand now best avoided.

First off try a new card reader, preferably on a different computer, then check that all the file sizes look about right. Next check the file prefix .NEF look right? Lastly can you upload a duff one somewhere so somebody else can try opening it.

I'm assuming you have already tried re-downloading them again.

Thanks for the replies, I used a card reader on the Laptop and a USB cable on my PC but have exactly the same issue on both.
When I get home from work I will upload one to see if anyone else can open it.
Cheers

I can't work out how to upload one of the corrupt photo's as I can't upload to Flickr etc as a Raw file.

Upload one to a file hosting like rapidshare or hotfile then either paste the link or email/pm people with the link.

Thanks Wayne, I am away for a couple of days so will give it ago when I get back.

See if the Adobe DNG Converter will convert them. I once had some corrupt raws - viewable but with sections showing just coloured bands and noise - and somehow they converted to DNG without a problem.
