Recently, I have noticed that I cannot access my USB flash drive filesystem (it was of FAT type, as far as I can remember). Fedora did not mount it automatically and
lsblk could not see the partition. So, I decided to create new partition (instead of wiping the device at first) with
The process was straightforward (
fdisk did not complain a bit), but I noticed that
fdisk asks me as a last step about removing a thing called "vfat signature":
Created a new partition 1 of type 'Linux' and of size 7.3 GiB. Partition #1 contains a vfat signature. Do you want to remove the signature? [Y]es/[N]o:
I am aware that happily creating new partition in such a case may not be the best thing. I do not know yet, what I would like to/should do. However, nonetheless, primarily I am curious, so I would like to know:
- What is a "vfat signature"?
- What is the reason that
- What is the purpose that
- Is it somehow related to a term that I have encountered in the context of Windows, "disk signature"?
- Why would I like to remove it or not?
I have searched for a similar question here, but found only this question which does not answer my doubts.
