Hfs corruption on 2tb Seagate internal HDD and strange error

[truztruz]

Hi,

 

I have a 2tb seagate internal HDD with 3 partitions:

 

1) 500 gb Mavericks

2) 500 gb free

3) 1tb free

 

The problem is that randomly 2nd partition gets corrupted and I have to use diskwarrior to restore it.

 

Today I had another problem, on my 1st partition where Mavericks is installed, I can no more paste files as I get an error of disk full (but I ave 300 gb free !!!!) and at the same time internet connection doesn't work anymore.

 

 

I don't understan if is a fisical disk problem (but seatools doesn't find errors on disk), or if is an hardware incompatibility that needs some kext to be installed.

 

Please help 

 

tnx
