Emptying the Expansion Floppy Drive

Hi!

I have a backup of my old Mac on an external drive called Expansion.

I tried to erase it with Disk Utility, but I got the following error messages:

---Erasing “Expansion” (disk4s2) and creating “Expansion”

---Disabling disk

---The volume “Expansion” on disk4s2 could not be unmounted because it is being used by process 530 (mds_stores)

---The disk could not be unmounted.: (-69888)

---The operation failed…

Is there any way to stop that process 530 or is there any way to empty the disk so that it can be used to back up the new machine?

Shut down the computer.

Disconnect the drive.

Reboot the Mac and reconnect the drive.

System Settings > Spotlight > Search Privacy… mount, drag, and drop the expansion drive icon into the Spotlight privacy panel to avoid Spotlight attempting to index the drive before launching Disk Utility.

Then launch Disk Utility and try Erase again.
