I rack up about 10+GB of RAWs every week (I don't shoot with a JPG copy). Usually keep them in internal HDD for quick reference, and in external HDD for backup. If I delete from internal HDD, will backup another copy on yet another HDD!
Anyway, I just came back from Nikon Service Center, with 2 unresolved problems. They said they'd get back to me again regarding these issues..
1) Occassional extremely slow writing speed
- Saving of picture takes 5 to 10 seconds in normal shooting (1 shot per few seconds at best).
- Completely random, happens maybe once in a hundred shots.
- Has not happened in burst firing before.
- Happens on both SD and CF card
2) Rear Sync Flash fires twice, at the start and end of exposure
- To test, set flash to REAR sync, and use bulb mode. For each exposure, the flash will fire twice. It should only fire when the shutter closes.
- NSC tried on their own sets and got the same problem
If you are getting the same symptoms, post here as well and see if we could get more clues to troubleshoot.
