formatting error while erasing SD cards
I was in the process of formatting a stack of 30 SDcards with disk utility, the same way I do all the time, which is to insert the card in the sd port on the side of a macbookpro, to erase the partition and format to fat32 because I use the cards for shooting with GOPRO and VIO POVHD cams.
Now, about halfway in the process, disk utility starts to give me this error message
And now every card I try to format fails like this. If I try to format the card as opposed to the partition, I end up unformatting the card and it needs to be initialized again. I really didnt change anything, and I cant see all my cards being deffective. I can still play footage straight from the cards, so I suspect something went wrong with the utilitty software.
Any idea how I can fix this?
MacBook Pro, Mac OS X (10.7.3), Server
