D800 trouble loading some nefs in CNX2

[njangka]

Hi there,

I did a shoot yesterday with the D800 and and got this message on 2 of the 50 nefs. I am using CNX2 ver 2.3.2 on Win 7 64bit. I can see the file on camera screen and also in explorer, just can't open it. Tried reloading the file, but get the same message.
Anyone encountered this? Any solution/workaound?

I don't use capture nx anymore to darn slow , i use my nefs and jpgs with PSE 9
and i import by cartreader not by cable to camera ..

i advise to copy the nef's directly to a folder on your laptop or pc or mac
then try to open them with capture nx

Hi Dirk,
Thanks for your reply. I am familiar with CNX and know the issues wrt performance. Since version 2.1.x or higher, speed has been greatly improved and I was OK with it till the D800 came along. In fact Photoshop became the bottleneck, so I bought a new i7 pc and migrated to Win 7 64bit.
I did not try loading the SD card directly to the pc, as I figured it would make any difference, but I give a try.

Hi Dirk,

I just tried loading directly form the SD card, and you know what...IT WORKED.
Thanks a million, looks like USB 3.0 isn't that watertight as I thought.

Glad to be of help..

The computer may be USB 3, but the camera isn't. It transmits at USB 2.0 speeds.

Also, as a general rule, we NEVER connect our cameras to the USB ports of computers to transfer photos. A damaged cable or USB port can send an electrical signal to the camera and fry it's very sensitive internal electronics turning it into a great paper-weight.

A third incentive, transferring from camera to computer is one of the absolute slowest ways. When transferring files from a 36mp camera, this becomes almost a painfully slow process.

With all due respect jerryph,
1) The D800 has a USB 3.0 port and transmits at much higher speed than USB 2.0
2) Maybe true, but on my D300 I rather take the risk than bending/breaking a CF pin
3) Not true if transfer is USB3.0 to USB3.0 (albeit not as reliable, hence my post).

will partitaly agree with jerryph.
especially on 2 ..

i used to upload my files (in 2007) with the usb cable to the camera but once i had a p&s turn up wicked i swore never direct but always by a cartreader.

when files are corrupted in a way that the software can't read it , it is the best to use it with a cartreader .

You are right, I just checked. The D4 is USB 2.0.

I'd rather replace a pin socket ($35 for your D300, for example) than an entire camera. Sorry. Besides, unless one is clumsy, it is near impossible to bend a pin the way they are designed.

Not in my experience. I have USB 3.0 on all my computers and if you looked under my desk right now, you would see 12 external drives... 4 USB 2.0 and 8 USB 3.0... zero reliability differences between them.

What I also did notice is that even though the USB 3.0 spec is 8-10 times higher than SCSI, my external SCSI drives still transfer about 50% faster due to 2 points:

- concurrent reads and writes... no SATA or IDE spec permits this
- USB spikes at the start really high, then peters out down to about 1/4 of it's speed, where SCSI starts at about 75% of it's max, climbs to 90-100% of it's max and stays there.

... and transfer rates from camera to PC are still about 1/2-3/4 the speed of when reading from a card reader. Try it and see for yourself.
