Bad Sectors on HDD

scotty92 · Sep 7, 2014

Hi all,

I had the 100% disk usage and extremely slow read/write speeds problem.
I think I've sorted it now, but decided to run HD tune to see what state my HDD is in.

The test came up with 5.1% damaged blocks (out of 955Gb)

Is it time to get a new HDD or is there a way of repairing damaged blocks?

Thanks

HDDs 'get slow' sometime after the 60%-capacity-filled level is reached. If you filled this up to 100%, then it's performing like you want it to - suuuu-looooowwww. (Ever drive around a huge parking lot that's almost full, looking for just one slot? Well - that's what you've done to a full hard-drive - it takes so much time for it to find any free space, and it's constantly "driving around". Fortunately, the User is the one with all the cars/data parked - free up a lot of space, and it's a lot quicker.)

I'd move (a COPY then DELETE, or just a DELETE and take the trash out) at least half of the data to another hard-drive, then run your standard weekly disk diagnostics.

I would say get a new drive if its getting sector damage you may get it in a core windows area and it will fail to boot and you could loose it all read this and decide on what you want to do

hard drive damage is a damaged hard drive and all at risk of data loss [opinion]

When bad blocks become visible it means that the table of reserved blocks has filled and the controller can no longer map out bad blocks. Your drive is in the process of failing and should be replaced ASAP. It could hard fail at any time now.
