Hi. I have a failing hard drive and I would like to attempt to fix or recover the data before filling it with zeroes or sending it for RMA. The smart readings is as follows :

C8 100 253 __0 000000000000 Write Error Rate
for convenience sake, i have modify the raw values to 10 [DEC].
Before I go into data recovery, I have one question about the readings above. It shows that current pending sector count is 3011 (spreading like cancer) but the reallocation event count is 0. Does that mean my hard drive has a problem with reallocating bad sectors?
As for data recovery, I did a CHKDSK on this drive (in Windows) and was stuck at cluster 4000+ for more than 12 hours so I aborted the operation. I have also tried free data recovery software like Recuva but they virtually cant copy any files from my hard drive (stuck at the first few % when copying something). Now, I have read about testdisk and spinrite. Spinrite looks like a powerful tool but I cannot invest that much money into it without knowing if it will tackle my problem. So I tried some copying with testdisk. Files below 500MB has a recovery rate of roughly 60% (the rest is partially or 0 bytes) while files above 500MB (max 20GB for this hard drive) has a failure rate of almost 100% (partially recovered or 0 bytes). These files are all video files and the partially recovered files can still be played on media players as much as they were recovered. However, most of my files are above 500MB.
What I assumed is testdisk copy and skip anything on bad sectors at all without trying to read them. It is probably best for the hard drive considering the number of bad sectors. I also read somewhere that spinrite has some methods to read these bad sectors. Trying to read bad sectors will cause bad sectors to spread even faster so I am not sure about forcefully recovering my data. As far as hard drive goes, I do not have more knowledge about it than any other average consumer. I would like confirmation on this matter and if there is anything else I could do about recovering the data. This is just one last shot before I zero fill it or send it for RMA so there is really nothing much to lose.
Thanks a lot.
p/s: I have posted previously on this matter but decided to dig deeper.
