HDD keeps disconnnecting

I have a one year old PC and for the past couple of days I have had an issue. I have two interal drives, one SSD where I have the OS, and one WD HDD. The HDD keeps disconnecting at random times and then reconnects after a few seconds. I've chekced the SATA cables, they are properly connected. I can't figure out what might be causing this. Any suggestions? Thanks!

My first move on such

Is a new SATA cable for that drive and change to another power cable from the PSU.

- Collapse -
Which one first?

Should I change both the SATA and the power cable or one and see if it fixes it? (also can't remember but is there a power cable going from the PSU straight to the HDD?)

Read below.

My bet is there are extra SATA power cables so I just swap for another. If you don't have a spare SATA cable try what Bob B wrote below.

This is free, takes the amount of time it takes to power off and not much longer.

Some want assurance this will fix it which I can't give but it's exactly what a good shop will do for you and charge 100+ bucks most of the time. Do it yourself and possibly save yourself that for free.

If this fails, then we need more PC details. Make, model of the PC, HDD and PSU to start with.

One more thing

OK so I am trying this right now. While making the cable changes I've noticed that my SSD which has Windows in is not in the OS HERE SATA on the mobo. Is this a problem?

- Collapse -
That was unclear to me.

Sorry but I can't grasp what you wrote about the OS HERE SATA means.

SATA drives have TWO cables. One for power from the PSU and the other is data from the motherboard. I haven't seen machines besides laptops that do this with one cable.

New Problem

Well now something more urgent. I changed the SATA port of my SSD which haw windows in it and now the PC won't boot into windows. In bios the SSD isnt even recognised. Help. I have an Asus Z170A mobo

That's normal.

You must not change the SATA port in use. For this round I see only asked to unplug and plug it in. Not to change which port is used.

Small steps. Don't add more changes than asked for.

Your making a mess

Your not following directions.
Your doing what you feel like doing.

Put the ssd back on the sata port it was on.
Leave the ssd alone for now.
Work the hdd problem first.

Start with just reseating the the hdd cables and test.
Depending on the results you move on to the next step.

Small mistake

Hey. Sorry for troubling you. The cause of the non bootable problem was because as I changed the power supply of the HDD I accidentally removed the power cord of the SSD. Now the PC boots and everything is recognized. Now if the HDD problem persists I do not know. Will keep you updated. Thanks Happy

Problem persists

Hello again.
I tried reseating the cables, the problem remained. Then changed the sata and power cables, and it seems to have been disconnected one more time. what else is there to do?

- Collapse -
Just one more time?

Once isn't enough to complain about unless it's the one time you used it.

I worry the HDD is toast. How do the smart values look in the Speccy report?

I'll run it now

It happened two consecutive times right now.
Here is one concern I have. Whenever the drive kept disconnecting I noticed through utorrent,as it couldn't find the torrent path. Also, this started happening frequently when I put some big torrents in utorrent. And for some reason, I believe/have observed that when it was open it was when it happened. As such, I've deleted the software. Could it be relevant to the drive's issue? (It's been one hour since I deleted it and no issue has come up, and I am using the drive)

Here is the report:

The drive is WARNING you

It's in failure mode. I see (05) reallocated sectors and C8 is out of whack too.

Looks like you should ask for a replacement if this is in warranty.

Mystery solved.

Thank you

Ouch, that's bad, it's only a one year old drive. Thanks, I will take the corresponding actions ASAP

No end of troubles from folk that use that. I don't want to open a TORRENT discussion here but bad stuff there even if when I use it for getting a Linux distro fast.

For torrent a nod to and qBittorrent

One last thing

I see. I made the switch to qBittorent. For the period until the retailer reaches out and I replace the HDD, what should I do it to preserve it so my data remains as safe as possible? Because I suppose they will transfer the data to the new one or fix this one, right?

- Collapse -
NO! They will NOT transfer data

YOU have to do that. You can boot a LIVE DVD of some Linux distro and do it easily using that file manager to an external media device like flashdrive or HDD.

- Collapse -
Only if you pay for such service.

Here that's over 150 bucks.

"We only lose what we don't backup."

Folk that wonder why this is said so often either wonder or learn why later.

- Collapse -
Thankfully most are

I backed up most of the important data when I saw that it began having problems. Is there any safe way to transfer my data to another HDD? I mean in the case of it being disconnected during transfer. Thanks

- Collapse -
The safe way is "ANY WAY"!

When this happens you use clone software that retries. Almost all do that today.

A test

Reseat the sata cable both ends.

Reseat the power cable.

- Collapse -
What exactly do you mean?

Reseat as in just pull and then reput the cables in the hdd and PSU? Sorry, english is not my first language.

Unplug the sata cable from the hdd and plug it back in.
Do it twice.

Unplug the sata cable from the mobo and plug it back in.
Do that twice.

Unplug the power cable from the hdd and plug it back in.
Do that twice.
