    Hi All,

    I have two partitions, but after noticing that 115gb for my second macbook air partition was too small I want to just make it one larger 256gb partition again. However, after I deleted the second partition and tried to extend the first (original) partition it keeps coming up with the error: "Partition failed with the error:

    Couldn’t modify partition map because file system verification failed."

    I then tried changing the original to 230gb and making the second just the remaining 20gb and this won't work either. In fact it won't budge from what its at now.

    Does anyone know how to get it to work?

    Cheers

    something has gone wrong, I'd back it all up and start again.

    I don't think you can alter the system partition. You could do a full TM backup and then disconnect the TM drive and then reformat your main drive as you wish. Then reconnect TM and restore from backup. It is not without risk so make yourself 100% sure and then recheck that your backup is valid. You may need to restore lion first before restore from TM backup so double check that you can do that from the lion recovery partition.
