Lost silver Seagate portable hard drive near the rose garden bench in Hyde Park containing irreplaceable files and sentimental videos.

I was in Hyde Park on Wednesday and believe I left my silver Seagate portable hard drive on a bench near the rose garden. It contains irreplaceable files and sentimental videos that I haven't backed up elsewhere. I remember packing my bag but must have forgotten to put it in before leaving. If anyone finds it, I would really appreciate getting it back.
