The D70 had some issues. A firmware update was issued in May of 2005, in part to correct some initial problems and bring the performance closer to the newer D70s, introduced about a year after the D70. The upgrade must have been popular, since I have encountered only one used D70 that had not been updated. The second notable problem was much more involved. Early production D70 bodies sometimes fell victim to the Blinking Green Light Of Death, sometimes call BGLOD, a problem traced to a batch of defective circuit boards in the read/write system. Nikon was criticized for not recalling them all, but instead issued a service bulletin offering to fix any D70 body that failed because of the defective component, in or out of warrantee. The service bulletin only covered the D70, and Nikon USA would service only those bodies that they themselves imported and warranted.
Nikon USA Imports Vs. Gray Market: A camera that is NOT sold though the official importer is called “Gray Market” and Nikon USA is under no obligation to repair it under warrantee. Check the serial number on the bottom of the body. If the first two digits are “30”, your D70 was imported by Nikon USA and if you get the BGLOD, you may be eligible for a free repair. I sent one of my ailing D70 bodies back and it was indeed repaired free of charge, but apparently some other photographers were not so lucky.

Just as well, since I can only speculate on the availability of parts.
- Error accessing memory card.
- Unable to create new folder
- Card has not been formatted for use in D70.
- Use Nikon-approved card. (Check page 192 of the manual. None of MY cards was on the approved list!)
- Check that contacts are clean. If card is damaged, contact retailer or Nikon representative. (I've seen CF cards that were damaged by a bent interface pin, so keep your cards and camera clean).
- Delete files or insert new memory card.
- Format memory card.
- Turn the camera off.
- Eject the card.
- Insert the card firmly.
- Turn the camera on.
- Camera malfunction: Release shutter. If error persists or appears frequently, consult with Nikon-authorized service representative.
"In extremely rare instances, unusual characters may appear in the control panel and the camera may stop functioning. In most cases, this phenomenon is caused by a strong external static charge. Turn the camera off, remove and replace the battery, and turn the camera on again, or, if you are using an AC adapter (available separately), disconnect and reconnect the adapter and turn the camera on again. If the problem persists, press the reset switch (see arrow) and then reset the camera clock to the correct date and time. In the event of continued malfunction, contact your retailer or Nikon representative. Note that disconnecting the power source as described above may result in loss of any data not recorded to the memory card at the time the problem occurred. Data already recorded to the card will not be affected." To see the original article, click here.May Day! May Day! A week ago, the Centipede stopped working and the "ERR" began was displayed on the control panel. Pressing the shutter release had no effect. I instinctively removed the battery and replaced it with a freshly charged one, to no avail. In desperation, I located the reset switch, pressed it, and the camera was resurrected! Overjoyed, I began clicking the shutter, over 500 times in all, trying to make the error return, which it didn't.Until the following week. This time, I photographed the Control Panel, thinking this would be a good topic for a blog, and when I finished, pressed the reset button with sublime confidence. And just like before, all was set to right. The camera, I'm happy to say, is still working.Epilogue: The Centipede may now be back in my good graces, but to make sure I don't take it on an assignment, I removed the neckstrap, a gesture indicating Centipede's demotion to "hanger queen". I still use it to test lighting and flash techniques, but without the neck strap, I won't accidentally take it with me on assignment. Serial Numbers: Because NikonUSA will only approve warranty repairs on cameras they import, it's important that you know which cameras entered the country "properly".

While this wasn't my case, I've added this link for more information.Click here.
