could not get VHB/MDB at block on USB Thumb drive

I'm trying to not have to shell out $100 for DiskWarrior and because im on a Macbook Air, with no media drive, so i think i'd have to shell for a usb optical drive too.... so if someone can help me with this stupid, stupid, occurance (which will teach me to NEVER use hfs+ again), I'd be really appreciative.

I have a PNY 64GB usb 2.0 thumbdrive and it pooped the bed on me....here is all the diagnostic information i can provide

from fsck_hfs -d:

Unable to open block device /dev/disk1: Resource busyjournal_replay(/dev/disk1) returned 16

** /dev/rdisk1 (NO WRITE)

Using cacheBlockSize=32K cacheTotalBlock=16384 cacheSize=524288K.

Executing fsck_hfs (version diskdev_cmds-540.1~44).

Block 2 is not an MDB or Volume Header

CheckForClean - could not get VHB/MDB at block 133512190

** Checking Journaled HFS Plus volume.

Invalid B-tree node size

(3, 0)

** The volume could not be verified completely.

volume check failed with error 7

volume type is pure HFS+

primary MDB is at block 0 0x00

alternate MDB is at block 0 0x00

primary VHB is at block 2 0x02

alternate VHB is at block 133512190 0x7f53bfe

sector size = 512 0x200

VolumeObject flags = 0x05

total sectors for volume = 133512192 0x7f53c00

total sectors for embedded volume = 0 0x00

from console logs:

6/29/12 9:30:42.000 AM kernel: hfs_swap_BTNode: invalid forward link (0x0a0d0321 >= 0x00001880)

all my files are flipping gone, but it sure kep the directories.....yay 😐

Thanks in advance for any help
