Hard Disk laggy

Hey guys I am considering to purchase a new HDD after a series of events that happened : Couple days ago my PC froze while I was playing a game, I wasn't able to close any processes with my Task Manager and I decided to RR the pc. After I did that my pc went to boot and immediately after I got the "Attempting to repair the disk %", it failed. Tried to recover it but unfortunately I wasn't able to get past the (windows couldn't start normally). I decided to reinstall my Windows and I went for a clean install, deleted the partitions, BUT when I tried to format my whole partition I got this : "Windows couldn't not format a partition on disk0 : error code 0x80070057". Tried to format it with diskpart but without success, managed a day later to install my windows(normally). Yesterday I had another freeze/lag during a game, and I've seen that the computer lags terribly... Did some checkups :

Samsung HD105SI

1) SMART returned to me with healthy and only one warning at my Interface CRC error count Current : 69 , Worst : 1 , Threshold : 0, Data : 16887 2) Tested the read speed ( HD tune pro) : minimum speed : 0.2MB maximum: 105,5 MB average: 65 MB

acc time : 20 ms burst rate 159 mb/s

Is my hard drive beyond salvation ? As far as I know there's no way to fix a HDD problem but with a replacement. Thanks and sorry for the long post

Apart from the other comments, did you perform a chkdsk X: /r ?

Sometimes your ear is better than SMART, try to listen close to the disk when it's on load if it is making strange noises.
