1DX+128GB+64GB buffer/write issues
« on: October 04, 2013, 10:24:21 AM »
I have a 1XD and mostly shoot weddings.  During a wedding I had a Lexar Professional 128GB 800x card and a SanDisk 64GB Extreme Pro 90mbs.  I was shooting RAW to the Lexar and JPEG to the SanDisk.  About 2000 pictures into the day I went to review a series of images I had just taken and could not because the camera was busy writing to the cards.  I do not spray and pray so I was confused as to what was happening.  The buffer never did clear and I took the risk of trying to shut the camera off.  Next a spinning graphic along with the message that the camera was still trying to write 14 files to the cards came up on the LCD screen.  I let it be for about 5 minutes and then felt that I had to move on with the day and wasn't really willing to stop using my 1DX.  I took the battery out and put it back in and was able to review the images and sure enough I had lost the 14 pictures it was trying to write.  It wasn't a huge deal because I had already retaken them with my 5D3.  I was able to take pictures again but I noticed that the red buffer light stayed on continuously.  I found out that the 64GB card was causing the issue so I swapped it out and continued without any issues.  My question is that do you thing the issues was with the camera or card(s).  I feel like I shouldn't have these issues with expensive cameras and nicer, newer cards.  However I know that crap happens.

You are right that it shouldn't happen - couple of possibilities come to mined: faulty card or 1Dx not liking two different branded cards for some reason.

Have you managed to replicate the issue since the wedding shoot?

IIRC there is another recent thread about a Sandisk card packing it in; The signs it gave were similar to yours.

I'd probably do better to invest more time and less money.

Not yet.  The only times I have had issues with cards they have been SanDisk.  Could be a coincidence but I am thinking about only using Lexar cards now.

So I had this issue repeat with the same card so I was thinking it is a card issue.  I am sending it back to SanDisk for a replacement.  However, I was at a wedding last Saturday evening with a Lexar Professional 128GB card in one slot and a Lexar Professional 32GB card in the other slot.  I had the the same issue where the buffer could not or would not clear.  I shut the camera off and took out the battery.  When I turned everything back on I had obviously lost the images still writing to the buffer but I could shoot again but the buffer light continued to stay on.  I kept shooting for a little bit and noticed the cameras was slower to write to the cards and the buffer continued to stay on.  It was like it was busy doing something and if I pushed it too much it would freeze up on me.  I decided to swap out cameras and use my 5D3 for the rest of the reception (which is so slow in comparison to the 1DX).  After I copied my cards to the computer I formated them and put them back in the camera and the buffer returned to normal.  I even shot an engagement session with no problems.  I either have 3 bad professional grade CF cards or something is wrong with my 1DX.  Any thoughts?
