Corrupted/Unreadable Partition

[chrio]

---

I so need your help now. I have two partitions and one is corrupted. See the image below.



First of all, i am using windows XP pro Version 2002 Service Pack 2. Here's what i did. This is an external HDD within an enclosure. I attached it to my friend's computer and created some Permissions under the Security options. I kind of messed up doing it (the permissions) because all of the subfolders are also "Access Denied". So, what i did was to do a system restore to undo any changes. And during the process of system restore, i turned off the enclosure and the whole process was cut short, when the pc restarted, the System Restore window appeared and there was a prompt that it did not finish the process successfully. I attempted another system restore, this time my enclosure is turned on, but there was a prompt about my drive J: that says there was an error and that system restore cannot undo the changes blah blah. Then i just hit OK then let the system restore task finish. It did. But when i accessed one of the drives/partition of my external HDD, it was renamed to Local Disk (J. then when i tried to double click it to open it, then this error appeared that says:



Is there, by any chance, a way that i can still recover ALL of the files under that drive? I can't afford to lose all of my files although i already backed up 80-90 percent of it. I still need the other files. Please do help me. Can i still recover the size of the other partition? It's a 138 GB partition, i would be devastated if the 138 GB won't be usable. This is a 300 GB HDD. I even tried the chkdsk /r and chkdsk /r/f using the windows xp pro CD, it did not fix the problem.
