Impossible to mount / repair partition

[saharG]

Hello,

After deleting Refit from my mac, I removed the extra partitions and resized my main partition.

My hard disk is partitioned into 1 main partition, and one more partition used as storage. Now i can no longer access / mount/ repair this partition after the resizing. Any idea how to fix this? I now get the error while trying to repair:

Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

Here is the Partition description

Thanks a lot for any help!

have you tried doing this from the recovery partition? (if you still can access it)
