Can HDD Dock cause/increase bad sectors?


Recommended Posts

I have hard drives in a Thermaltake HDD Dock (http://www.newegg.ca/Product/Product.aspx?Item=N82E16817153112) and I was wondering if it is possible a dock can cause or increase the amount of bad sectors. I have had issues with the dock where I had to force shut off the dock since it has trouble reading the disk (indicator light goes crazy). One of the disks ended up developing 4kb in bad sectors, now it has increase to 52kb. I am not sure if it is just the drive dying or if the dock could also have made the bad sectors worse?

Just don't hot-swap or move mechanical drives around when powered on (3.5" consumer versions mainly) in these vertical docks and you'll be fine.

 

Moving a drive around at an angle when powered on would make it more prone to head issues and an accidental knock certainly won't do a consumer drive any good.

The dock itself won't produce bad sectors, it's the drive. One thing to note with these docks though is the hard drives are vertical, so the head needs more effort to move up than down (whereas horizontally it's equal) so this can cause failures to occur much quicker, and the bearings are not equal either, always best to get a horizonal dock.

It can either be as said because they're in vertical position or also because they run at higher temperatures compared to a well ventilated computer case (of course it depends on the drives, some run near ambient temperature, some can easily reach 70
