Everything started one year ago, my PC started to slow down, got some freezes, and the HDD light light up like crazy, the task manager showed 100% disk usage, and the SMART of HD Tune showed a warning on Reallocated Event Count ... So i believed it was a problem with the HDD, and exchanged it to ST500LT012-9WS142 (Seagate Momentus Thin), on my Samsung Series 5 Ultra.

Some months ago the slow down started again, and the freezes. It freezes when i open explorer, try to open some files, use Word, but rarely when using chrome.

So, i did smart tests and CHKDSK, without success, on Seagate tools the HDs pass on SMART, but on HD Tune, it show Warning on Reallocated Event Count (AGAIN), below are the data:

CHKDSK Log: https://app.box.com/s/linl64yzo5h5vroolqjbn2xlkfmgnrgq
Active SMART (no warnings): https://app.box.com/s/kh5oefxqcyiwmxvni56v5f0md0719rmi

HD Tune Warning: https://app.box.com/s/szu1vxqfvltkle4e8xpj1g921j0lxw7l

I noticed too, on the freezes, when navigating on explorer, and opening files, the Exeplorer.exe on task manager use like 1~2Gb of memory... so for that i tried use Procmon, and i have the Log of it ( https://app.box.com/s/x9ux82myz3363nv057mf5k908k0skucu ), but i dont know how check it...

And today, when i woke up, my HDD from the sudden show 0 space available (it had 100gb!), so i am making backup now... and i dont understand why that... another HDD with the same problem ?

Thx for the Help

Thats just one of the many ways hdd can die and why you should always have important data backed up already. You need to be proactive with your important files and back them up long before your harddrive decides to not work anymore otherwise your just one 'dropped laptop' away from losing all your files.

Hi there Kaue Lima,

It's good that you've started backing up your data.
Mechanical drives eventually fail. I don't really think that something in your system is causing that. Bad sectors appearance is just the most common cause for HDD failure. As popatim said, you should always back up your important data, even if the HDD operates properly.
In case the HDD is under warranty, just RMA it.

Sometimes the writing zeros process could help, or at least slow down the failing process, in similar cases. Keep in mind that this is data destructive.
