So forgot to lock the sd card this am. Downloaded data (windows 8)Put card back in the S9 and it said ,Are you Sure? You want to erase all data? Yes/ No I clicked no and it said please remove card. So I did . Thinking oh crap I've read about this on the forum.....
A friend using linux found a hidden directory called "system volume information "that had just been added and deleted it .I placed the card back in the S9 and plugged it in and it seemed like a long time it said reading the card....
So with the help from this board and my friend , trust all is well.
System Volume Information is a hidden file unique to the NTFS file system.
By deleting it, likely your machine thought the card needed to be reformat; so that's why it seemed to take so long.
I think, but am not certain, that just permitting the machine to delete the data on the card, it would have had the same effect. The data is stored in the machine's internal memory; and the data card is just a means of reading it out. Has anyone tried just letting the machine "delete the data" on the card?

For 37 days, I have moved an unlocked card back and forth from Win 8.1 with no ill effects.
The cards are formatted Fat32, not NTFS.
