My PC's internal HD is BAD and I ask if a WD1003FZEX may replace it without hassle

The ED1003FZEX description page at Amazon, shows this WD drive as “Similar” to the now discontinued OEM (and almost defunct) HD in my desktop PC (Acer Aspire X3810 with Windows 7 Home Premium 64-bit SP1 installed) the OEM HD is a model ST31000528AS and its driver is a Microsoft Version  6.1.7600.16385. I ask about hassle free replacement because I have some but not so much expertise as a full time technician. Any help is strongly appreciated in advance.

If the specifications are similar then you should be fine.
