Hi all, wondering if anyone could give me some advice here. This drive was purchased around August 09, only installed this drive in my secondary desktop like after xmas. Like I said since this PC is my secondary desktop I hardly use it much, only turn it on from time to time to do updates on it. I have Windows 7 Ultimate on it. But yesterday after doing an update(not sure if it has anything to do with it) after doing a reboot I started getting a message "Windows detected a hard disk problem". I did some research on it and have used the HDDScan app and this is what it found. Also in the process of doing a Check Disk right now, not sure if it will help. Is my hdd going or can it be fixed. Or should I just replace it anyways just in case. Pretty sure there's still a manufacturers warranty on it.

Thanks.

Oops I think I made a boo boo, I just realized I only pressed the S.m.a.r.t. button and that's the info I provided in the previous post. I am running the tests now.

You have a bunch of bad sectors, you should not run checkdisk at this point. RMA time!

Dammit! I was afraid of that. It's a good thing I only pretty much have Win7 on it and nothing else. That would also explain why the hdd was running really slow for no apparent reason. Funny it's pretty much a brand new drive.

Thanks drc

BTW how can you tell there are bad sectors on the drive just by looking at the chart? What info there would tell you that your hdd is bad?

To answer your question:

Specifically with regards to the bad blocks, the two SMART attributes below:

Num Attribute Name Value Worst Raw(hex) Threshold

001 Raw Read Error Rate 001 001 00000000-8C7B 051
005 Reallocation Sector Count 122 122 00000000-0269 140

What you have to understand is the threshold value on the very right needs to be LOWER than the (Attribute) Value and Worst (Value) fields, not higher as so many people believe.

Therefore, the manufacturer's LOWEST acceptable number for Raw Read Error Rate is 51, however yours is 1, which is the lowest value possible, meaning you have a very high number of Read Errors being reported.

The Reallocation Sector count threshold has also been exceeded, meaning that the drive has reallocated more sectors than the manufacturer has stated is acceptable before it can be deemed failed/failing.

In addition to the link provided by unknown20010, which provides a very good overview on SMART attributes, here is another one that explains the values.
