Can anyone help me and maybe tell me what this is?
First time I noticed it in the review info page.
[05] Reallocated Sector Count:                                                  100/5, Worst: 100 (Data = 50,0)



Thanks

That means the drive has found problems with 50 sectors and needed to reallocate them from the reserved pool. Basically it's a warning that there are bad sectors appearing.
