Need advice for buying a HDD

I need your advice for buying a HDD.

Let me explain: I have 2 250GB hard disks, one dedicated to my Linux environment, the other Windows. I move my sensitive information from one to another to minimize the risk of loss.

But since a few months my windows HDD has more spams. In addition, XP is often having a problem. For example, today I checked the hard disk for errors and it found around 20 bad sectors. Eventually I fear for my data.

I wonder because it has been 2 years and I had no bad things happened (although used 7/8 hrs/day on an average). Is this the end of its life?

So to replace it, I want a reliable disc (no need of quantity since I will not store movies or download things).

I would say you should go for Western Digital WD 7200RPM 640 GB SATA HDD 640GB.

Just see this http://cgi.ebay.in/Western-Digital-W...130124001r2023

Tell your budget and then we can tell you what you can buy in that budget.

Thank you for your replies. My budget is around Rs. 4000. Western Digital 640GB hard disk really looks cool but I think I should look for 250 GB. I guess I usually use it for few games, graphics design, internet surfing, not large files (no movies at all).

From what I know the Seagate drives are very reliable. They are good discs in all. Just go for 250GB Seagate Barracuda 7200.10 hard disk.

No thanks because my brother has given me a Seagate hard disk drive few months ago. But unfortunately it never served (just a week or two).

Seagate is not bad if guaranteed 5 years apparently.

Well I have used a Maxtor DiamondMax 160GB and a 250GB DiamondMax hdd, and it is really noisy! I replaced it with Seagate 320GB, it is also not perfect but it is much better. I have also used Samsung HD400LD which has very disappointing performance. Western Digital WD6400AAKS is the most reliable according to me.
