GParted fs check wiped disk - possible to undo?

I connected a fat32-formatted USB drive to my system. dmesg showed:

[ 4057.783200] sd 6:0:0:0: [sdd] Optimal transfer size 33553920 bytes not a multiple of physical block size (4096 bytes)
...
[ 4064.091218] FAT-fs (sdd1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

The drive's used with MacOS, Win and Linux, hence fat32. This has happened a couple of times before as there's been short power cuts. As usual I used Gparted to check the disk, being too lazy to man fsck to check out the options: This time however it didn't just check the disk, it wiped it completely. Syslog tells me nothing:

/var/log/messages and journald aren't any more helpful. The disk itself is fine, it's just empty instead of containing the data I've stored there. The disk is unmounted. Is there any way to recover the data? Command sudo systemctl cat media-pg1-E93B\x2d1A8F.mount reports No files found for media-pg1-E93Bx2d1A8F.mount. I remounted the disk and rerun the command, but it returned nothing. Syslog after remounting:
