Does This Mean My Memory Card Is Corrupt?

[68lbs]

Just opened some holiday snaps and found two images were buggered! See...

Anyone seen this before? Do you think I should dump the memory card, or is it more likely to have occurred during transfer to the Mac?

I'd give it another try or two - it may have been a transfer problem.

Try transferring again. If the same defects happen in the same places then it's the card and it needs to be dumped. What make is it?

if it's not the case to all photos, i would assume it's something wrong with the camera. it may be the interruption when transferring images onto memory card. it happened twice to me, only on two shots.

Have you another card? That looks like a camera problem to me.

Normally, if a problem occurs when writing or transferring data, the software will know about it and tell you. Whenever data is written, the software does some simple testing, e.g. checksum tests.

So, if the card was corrupted, it is likely that the camera would have displayed an error message, at the time you took the photo.

Same situation, if the data was corrupted during transfer to your Mac. You would have seen an error message.

Well, after reading this as I was going to bed last night, and a brief moment of panic, I copied the files again...

And all was well. Not sure what happened, but looks like it wasn't the camera at fault... phew!

I had this once and it was the RAM inside the computer. Download and run "memtest" and see if it reports any errors. Or if you are using Windows7 there is a built in memory test.

to me it is a memory issue(on the computer), you can see that by just comparing the picture read on the camera. If it shows well but not on the computer you know which one is wrong.
