Hard Disk Monitoring

Greetings,

I have a problem with Seagate 1TB 2.5 inch hard drive, every time when i start copying data on to this drive he starts with transfer speed about 100MB/s but suddenly from 100MB/s slows down 355KB/s and weak sectors showing up.

Is there any way to fix the hard drive to function normaly?

Thanks in advance.

Please check the page suggested in the text description of Hard Disk Sentinel:

as it describes what are these weak sectors, how they may appear, what can cause them (usually cables, connections, power source, sudden power failure/reset, generic system instability) and how to fix and avoid them.

You'd need to check/verify all of the above - and then using the Disk menu -> Surface test -> Disk Repair is the best way to improve the situation if the amount of weak/damaged sectors is low.
If the drive reports lots of problems (so low health) then you may need to use Disk menu -> Surface test -> Reinitialise Disk Surface test (when the disk used as secondary hard disk) to stabilize all problems and improve usability.
