After defragmentation ( 48hrs) my HD makes whirring sound

By SednaWu ·
Hi everyone,

Since my computer was slowing down, I decided to do a full defragmentation. I have two harddisks, one of 150 GB and one of 1 TB (if I remember correctly). I hadn't used my desktop computer for over two years. Then I defragmented it with MyDefrag and it took a whopping 48 hours (!!!) to complete. Now upon rebooting, my system was incredibly slow AND it seems my HD actually broke down as now there is a whirring sound (very loud and much louder than usual) Thank God not yet any clicks, but I think I have no choice but to replace my HD. I'm running diagnostics as we speak to see which disk it is, but this completely sucks.

1. Is this caused by the defragmentation? 2. How come the defragmentation took so sickening long (They are a NTFS file system.)? and 3. Should I just go ahead and buy a new harddisk and give up on this one? Or is there any way I can fix it? (Besides CHKDSK which is a temporary fix)

Thanks for the help.

Well in order asked

1 no it's not caused by running the defrag utility though if the drive was on it's way out to. Silicon Heaven running defrag wouldn't have done you any favours.

2 depending on how badly fragmented the drives where it can take a very long tine to properly defragment the drive. I personally run defrag several times a day on 3 TB drives to stop them becoming to badly fragmented, but if it's not run often you may need to run it several times to properly defragment the drive/s. The most likely possibility here though is that the drive/s where starting to fail before you ran defrag so it took muck longer than it otherwise should have and was the reason that the system was slow to begin with.

3 the best option here is to test the hard drive with it's makers testing utility which can be got from the drive makers Web Site. This will tell you what exactly is happening with the drive and what may be required, though with any noise this tends to indicate a mechanical problem with the drive which under normal circumstances is beyond the adverse users ability to deal with. When drives start to fail it's always best to backup any data on the drive and replace it.

If you do not know who made the drive/s you can use the Ultimate Boot CD drive testing utilities to test the drive/s and as it's free to download and use with most of the drive makers testing utilities it's probably the best suggestion as it not only let's you test the drive/s but also most other parts of the computer. As these utilities also don't run in Windows the UBCD has everything required to test .

Harmonic vibration

by mjd420nova In reply to After defragmentation ( 4 ...

Sometimes a head servo and a spinning platter will create a vibration that can create a sound, some whir, others hum. Another defrag may result in thae head coming to rest over another spot on the platter and elimnate the noise. 48 hours to defrag tells me it hadn't been done in a while, if at all. Another this soon after a recent one should take very little time. Sometimes the problem arises after a WIN update and that's when a defrag would be called for.
