Originally posted by Kerrowdown I buy what IMHO consider to be the best cards in the first place (SanDisk), so I transfer images, then format them in camera and go fill 'em up again.
I treat my cards as consumables, like film was in the old days. I still consider cards to be relatively cheap in the overall scheme of things.
My images are in important to me, so I constantly rotate my cards... after a few months, I bin them and buy new ones, first in, first out.
With this regime, which maybe some folk would consider as "overkill", to date I've never had an "expensive" failure.
I use a combination...
In most cases:
* take the card out, copy the contents to the HDD of computer where it is backed up
* safe the contents on the card untill all files are processed.
This way I have an 'original backup' on the SD-card untill the processing is finished.
After that I delete the contents (subdirs) on the card and re-use it.
Sometimes when I'm short of cards and have subdirs on them that are not really processed yet, I need to switch cards halfway. I do have multiple though.
But a big problem with my camera's - als a K-30 - is that not all cards work well in the camera. I bought several that work well in my small canon but not in the K-30 and others that work well in the K-30 but not well in the Canon...
Last time a new Sandisk 64GB card for the K-30 seemed to be working but when zooming in the photo's were all only course pictures and only preview. (with multiple K-30's, reformat,different versions of firmware and so on), though from the same brand and type the 32 and 128 GB cards were working. So the 64GB card ended up for the little canon and the 32 GB from the canon (which is plenty in that camera) ended up in the K-30 (which is not much if you also make movies).
With movies and pictures combined, I sometimes do not have enough space on a 128GB SD-card in a project of 1 or 2 days...
