........and don't use Lexar cards

Actually, I use Lexar cards and don't have a problem with them. I also use Sandisk and don't have a problem with them either.

Actually, I've found the opposite.
Of all the cards I've had trouble with .. they have almost all exclusively been Sandisk cards .... and one Samsung micro SD card that went bang.

Over the years I've had tons of CF cards(mainly) for the cameras. Very few SD cards, and many micro SD(for phones and various other devices).
micro SDs seem to be very fragile, or the devices that use them may be causing issues

I still have many of the CF cards of various brands from about 10+ years ago, Adata, Patriot(back when they were a noname company!) RiData!! a real cheapie many Sandisks and so forth. Lexar is the only one that works in the D800, but D70s and D300 can all use any of the CF cards I have, even the really old 1G cheapie versions.
Whether it's a good idea to do so, especially with the D300!!, is something to think about tho, as speed is very important on the way this camera operates.

My two best cards are definitely the Lexar and the Patriot cards.

I'm down to my last 4Gig Sandisk CF card(from having about 6 of them) and I don't use it. Too many times it's corrupted images on the D70s(my son uses it) and I won't risk it in the D300 or D800.
So, one of the AData cards is permanently set in the D70s now, with the Patriot and the other AData card for the D300.

i did say that with tongue in cheek however there was one card used in my gps that continually failed and when swapped to a new brand there was no further problems. All brands have difficulties at times but some fix them quickly

Well, (back to the card) see what it does in a computer. If it works there and not in a camera,
then there might be a compatibility issue.

Over 5 years ago I got my first DSLR.
I bought a SanDisk Extreme card for my camera.
I have been taking the card out of the camera and placing it into computer to transfer images. Obviously I've also then placed the card back in the camera. I'm still using the first card I bought. I formatted that card once at the start of my DSLR journey.
I'm happy with SandDisk and wish it was this easy for others.

That's great, but I would (& do) format my cards in camera periodically. I only use Sandisk cards myself (CF & SD).
