Hey, I'm just looking for some advice/input on this issue that I've been having.

I have 3 internal WD HDD's 1TB, 2TB, 640GB and one 500GB external(different make, no issue). The 640GB is my boot drive and hasn't gave me any issue. The other two randomly will disappear in My Computer list(also disapeared in device management and BIOS)

What happened recently was that the 1TB disappeared(but the other two were fine, so I left it, for the time being), then later in the day the 2TB disappeared as well(which was an immediate issue for my attention since I use that drive for stuff regularly). I checked device manager and it didn't list either the 1TB or 2TB drives. The BIOS was only detecting the 640GB and the external drive. I also did a system restore to no avail.

So I opened it up and cleaned/re-plugged all the power/sata cables and now they are showing again. I had this issue with the 1TB or 2TB in the past(only once and it fixed itself with a reboot only), but this time it worried me since a reboot didn't fix it and all I did was re-plug the cables. I should mention that I think 1 or more are making some noises at times(comes and goes).

I don't backup stuff usually but I'm now transferring all important stuff to my external drive(luckily). The 640GB and the 2TB are still under warranty. I'm going to try and figure out which HDD is making the noises.

Just curious if anyone has any input on my issue as if they are starting to fail or something.

Thanks.

Head to support.wdc.com and download the hard disk test software. It can help determine if you have a failing drive (bad sectors and read/write errors)

**EDIT** As for reseating the cables, do you move your system a lot? Inspect your cables too, they may be faulty (replace if you have any extras)

Thanks for the answer. I'll run the WD DLGDIAG with extended tests as soon as I'm done transferring data, and report back.

There was quite a bit of dust inside the machine but the cables still look mint condition, the machine doesn't move often at all.

A lot of dust could cause your drives to get hot if they are coated with dust. Which brings our attention to heat. Excessive heat will cause HDDs to fail. So check for failing drives, if they are going bad, replace but we also need to find out WHY they are failing
