InnoDB: Unable to lock error 45 when starting mamp

i am in the process of moving the db for mamp to my remove drive and it is almost working i think but whenever i start mamp mysql won'开发者_Go百科t start and if i check the error log i come across this:

i also found this question but couldn't seem to find a way to make that work for MAMP, what am i doing wrong, is it a permissions problem ?

PS - Yep, my drive is called WALL-E :)

Probably an issue with filesystem level file locking. Try starting Mysql with --skip-locking. Im not sure how to do that with MAMP as I'ver never used it. Look for a place in its preferences where you can supply a custom options for startup.

Alternatively you might be bale to customize the mounting of removable media to enable locks with autofs, but my autofs-fu is weak so i cant give any pointers there.
