Thought for the day: Recording Media failures and sources
Recently I was asked a few questions by someone who was having problems with their SD cards. I feel that you should be aware of the following:
- Recording media dies. Always. Maybe after a few years usage, maybe sooner. But it will die and your usage and backup plan should include that you will loose all your images on it without a good backup system. Not one backup, but a system of updated backups.
- If a piece of media (disk drive, SD or CF card, etc.) starts having errors, copy as much as you can immediately and get rid of the bad device. Don’t save it for later.
- You don’t generally need to buy recording media from your camera vendor. For example Sony makes the TOUGH SD cards. These are fine cards but they are about 4x more expensive than the standard cards. And the standard SD cards are rugged enough to go through a clothes wash (don’t ask me how I know this 🙁 ). In a similar way you don’t need to buy a filter or intervalometer from Canon for your Canon (or from Nikon for your Nikon). Third party devices can be excellent.
- You don’t want to mix your formatting. For example you should
- Never erase images on a card
- Always format the card in the camera you are going to use it in
- Never format (for example) a card on you Canon and then try to use it in your Pentax (it may work or it may be a huge mess).
- Your recording media can effect your work speed. In particular the write speed of your SD or CF card should match how fast you want to take pictures. If you are shooting Birds in Flight (BIF) rapid fire you want to have a card that can clear the buffer of your camera quickly so you can take more inflight pictures. If you are shooting flowers on a table or similar, then something slower and cheaper will work well.
- If your camera has dual card slots you can use them in several ways. I use mine to generate a backup SD card on the fly. In the past 15 years I have had 2 SD cards die on me and I lost everything on the card (after trying recovery software). And if the card dies, after trying to recover the images, I toss it. It isn’t worth the money to try to reuse a failing card.
- RAID can be excellent, if used right. JBOD (Just a Bunch Of Disks) can also work very well, if used right. But both need offsite backups on a regular basis.
- Remember, your CF, SD and Disk Drives are going to die. Most disk drives are fairly reliable for 3-5 years, then their failure rate goes up. How much data are you willing to lose? Does that match your backup strategy? Don’t have a backup strategy? Then you can be sure you are going to lose some images you made.
