Mkfs.fat Device Or Resource Busy
I’m trying to format a 16 GB SD card to FAT32. Either it won’t find the device or it gives me the titular error message.
mkfs.fat /dev/sdc
I have tried “ejecting” the drive and reinserting the card. I have tried inserting another card, checking to insure that I could see its file, ejecting that card and inserting the target card. If I do not umount it, busy, if I don’t, not found.
What is the incantation for formatting an SD card.
BTW I am using CentOS 7 and a USB adapter.

First of all, doing it *without* a partition table is not going to work (well mkfs.fat is not going to care (once you deal with the other error). Since you are formatting iy FAT32, I’m presuming you will be using it in some device
(eg camera, mess-windows machine, etc.). You want an MBR partition table
Thanks much!
That was it. It did care. At one point I was even told something like, won’t do it, partition table.
Actually, I’m trying to update my BIOS. The instructions I found require FAT32. https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Trying-to-update-the-bios-on-dc-5800-mt/m-p/5746185#M134271
I used eject from the GUI and umount from the command line.
