I'm really banging my head against the wall here and would appreciate whatever insight any of you can provide!
A couple months back I bought one of the new Lexar 16GB 1000x CF cards. Took it on a weekend trip and when I came back and uploaded all the photos to Aperture 3, about 60% were corrupted. I was really disappointed, but figured it was a one off occurrence. I returned the card.
I bit the bullet and bought some more during B&H's current sale, thinking what are the odds it would happen again? I've used Lexar for years with no issue besides the one time. This time I made sure to format the card in camera as I had read that was the best way to start. Took some photos this evening and this time every single photo is corrupted. The embedded jpegs are fine, but when I click on each individual photo in Aperture (or open them in Photoshop), the RAW itself is totally messed up.
Really, what are the odds of this happening twice in a row with two different cards? I wonder if it could be something else, but I've updated all the software and I've tried it with several different RAW viewers and get the same result. Could it be the camera? I've never had any issues with the SanDisk SD cards I use but really wanted the speed of the latest CF. It's really unnerving not being able to trust your memory cards.
do you format the card each and every time you put it in the camera?
if the card has been read in a computer you should format it when inserting into the camera.
computers leave files that can corrupt cards
Often a bad card reader does this, set your camera to Raw only(no jpeg) and only one card, and see if the files can be viewed in the camera. Then load them into the computer and see if that works. If they are corrupted, try downloading direct ley from the camera or using a different card reader.
Its possible that your card reader is not compatible with the new card.
I saw someone else posting a similar complaint and they made it sound like someone else also had. Hope it's all nothing. I've never used the 16GB ones only the 32GB 1000x cards. So far, no issues for me (three different cards).

Not so sure about this. At least I have never experienced it and have frequently only partially filled a card, downloaded it, and continued to shoot on it without reformatting.

It's the first thing I thought about when reading this. If you can, try another reader.
I downloaded the photos direct from my camera and had no issue. To be fair, I did the same a few months back (my old lexar reader couldn't even read the new cards so I was forced to use the camera) and I still had about 60% corrupt files. This time everything worked great so I'm going to try a few other cameras/readers and take a whole bunch of test shots and see what happens.

No issues with mine 32gb Lexar 1000x however I can't see any significant difference to mine Sandisk ExtrimePro 32gb UDMA7 besides price Both very fast and good cards and I shot over 1700 raw's yesterday while Atlantic Citi airshow using both cards. Great for long shutter button press on high fps with 5D3, didn't miss anything I like to shot.
I actually wrote to B&H last Wednesday asking when they'd have more stock of the 16 GB and 32 GB 1000x Lexar CF cards.
Here is part of the response I got, which also includes information about uploading the pictures to your computer. Don't know if this applies in this situation or not, but it might be of some relevance...
"This is a new item being released in limited quantity. We are accepting orders and they will be filled in the order they are received. An authorization for this product will be processed upon placing the order. Your credit card will only be charged at time of shipment.
And Lexar was kind enough to give each photo salesman a 32GB 1000x card which we promptly found a minor issue: you can only download the photos using your camera or a USB 3.0 card reader such as this:
LEPCRU3.0 <----- Please cut and paste (or type) this into the search box on our website and click "Go"
It is very odd but even if your computer only has a USB2 interface, you still need the USB3 reader for the 1000x cards.
Our website is live with our stock and current pricing. Please add the items to your shopping cart to determine the shipping costs, shipping options and shipping duration.

Hmm that is bizarre. My computer has USB 2.0 interface and my old card reader is for sure only USB 2.0 and it read it fine. I did get a faster firewire reader a few weeks later though, but before that I never noticed any issues.
Maybe it bugs out only with certain USB 2.0 readers.
Can I use a CF 6/UDMA 7 CompactFlash memory card with older host devices?
Yes! All LexarŽ CF memory cards built with CF 6/UDMA 7 technology can be used with existing CF and CF UDMA devices (backwards compatible).
Pairing your CF 6/UDMA 7 enabled CF memory card with a CF 6/UDMA 7 enabled host device is recommended to fully take advantage of the performance benefits from your CF 6/UDMA 7 enabled memory card.
We are sorry to hear that you are having problems with your Lexar Professional 1000x CF cards. It sounds like you may be having problems with your card reader, as the Professional 1000x CF card should be compatible with the 5D Mark III camera. Does your reader support UDMA7 and feature the latest updates to ensure compatibility? If you are looking for a reader that will work with your Professional 1000x CF cards, we recommend checking out the Lexar Professioanl USB 3.0 Dual-Slot Reader: http://bit.ly/Ot8Ose
I never had issues with my first 32G 1000x card that I've used since March. Then I bought two more of them a few weeks ago, and when I first used one of the two new cards (only about 50 1DX raw+J images taken), I got the same problem that the OP describes. I reformatted the card in the camera again and it's been good since. However, the card got a red dot sticker now so I know not to use it on one of the more important missions, until this is clearly resolved.
BTW I used a plethora of card readers to download the images, including Lexar's own USB3 reader. So that's not it.
I have a couple of the 32GB 1000x cards and have shot, transferred and processed images successfully from my 5D3 onto my iMac using an old Kingston 19-in-1 USB2 card reader. No problems so far.
Note:
When I get a new card I always format it for the camera I'm using it in. If I know that I'm using it in the same camera, I don't re-format ever time I use it again. If I change cameras, the card gets re-formatted.
My wife just had an issue with her 1000X and her SanDisk fw800 reader. about 75 files out of 500 would not tranfer (failed on iMac)
Tried it in my Lexar Expresscard reader and it read / copied perfectly.

I had a kingston usb 3 card reader that would periodically corrupt my card when reading. Then I switched to lexar USB 3 card reader and there has not been a bump since. Try installing an updated driver or switch card readers.[ I have a mac and a usb 3 card that states its compatible with Lexar reader]
At USB 2, there has never been a corruption - but my hair was turning grey waiting for the copy to end.
As an interim measure copy the raws to a file and then import to Aperture. That worked for me. Even though Aperture mixed them up, I was still able to copy them to a file, delete the corrupted in aperture, and then re-import them.
My first post here. I've had a problem with my 5D3 as well and these cards. But in my case, I think the camera is killing the cards. I put them in the camera to format, and the camera kind of locks up for 10 seconds then I get a message that the card cannot be formatted. I've destroyed 2 1000x and 2 600 x cards in about 3 weeks. I sent it to Canon along with the cards, they sent it back with new firmware and my settings changed but no notice of whether they fixed the problem (they never tell you anything.) Today I ruined another card, so I am going to try a sandisk, but probably just sell the camera and give up, and buy another 1Dx. Since the early days of digital I've never had a SS card fail and I shoot professionally and about 200+ days a year. I am religious about copying and formatting the cards. I can't believe that I would have 4 bad cards in a few weeks, but I am sure that Canon will never admit that there is anything wrong. So now I have a camera I can't trust... I'm using the Lexar expresscard reader with the 1000x cards and it works fine. I've also used an old sandisk USB 2 reader that worked fine. No issues at all except for what the 5D3 is doing.
Well I've put a few months of heavy usage on some Lexar 1000x in my 5D3 now (read with a firewire Gold Flash Fire Wire800 no-name brand card reader) and so far, it's all been good.
My Lexar cards were from two different sources a number of weeks apart in purchase.
Both very fast and good cards and I shot over 1700 raw's yesterday while Atlantic Citi airshow using both cards. Great for long shutter button press on high fps with 5D3, didn't miss anything I like to shot.
