Don't touch the drive - don't save anything to it, don't create any files on it, don't even open any files on it.
Luckily for you you ran
clean on its own, which only wipes the first and last MB of your drive:
On master boot record (MBR) disks, only the MBR partitioning information
and hidden sector information are overwritten. On GUID partition table
(GPT) disks, the GPT partitioning information, including the Protective
MBR, is overwritten. If the ALL parameter is not used, the first 1MB
and the last 1MB of the disk are zeroed. This erases any disk formatting
that had been previously applied to the disk. The disk's state after
cleaning the disk is 'UNINITIALIZED'.
This means that the vast majority of your data is still there, even if you've deleted the partitions that make them visible.
