Hi

 

I've had 2 external hard drives for over a year and recently the powered hard drive has started playing up. Occasionally (i think only when booting from off) the powered drive isn't showing in windows, and it seems like i have to unplug the power and plug it back in for it to work. I did that today though and it took unplugging the power, and then the power and the usb to get it to come back on in windows. It's only started happening recently and it's not that frequent so it's hard to give definitive details, but i'm a bit concerned because it's a 3Tb drive which is basically full.

 

I'm running windows 7, the drive is a Samsung D3 station (Seagate st3000dm001 inside), and I have usb selective suspend turned off. Does this mean the drive is potentially failing or is something else happening? I've done a disk self test on it and it was fine if that makes any difference.

 

Thanks

Everything you describe suggests to me that this drive is in the process of failing, as it's the mode shown by all of my desktop drives (three) that have failed.

 

I'd suggest you download SeaTools for Windows and run the Short Drive Self Test for starters.  If that comes back clean, considering running the short generic test or long generic test.  Normally I'd say long but for a 3TB drive that will be a very long test indeed.

 

Regardless of what comes back, if the data on this drive is valuable to you I would strongly advise getting a replacement drive and copying everything off of the old one ASAP.  It's very cheap insurance.

That Seagate drive was a disaster.

Not sure why but every time i post it's blank so i have to write the message out again... Why can't computers just work!?

Anyway, i did the disk self test which it passed and i've just finished the long generic test which passed too. Does it still seem like a drive that's on its way out?

Anyone? Does it still seem like the drive is failing if the long generic test and the self disk test passed?

If both tests passed then the drive is okay. Does this drive show the same problems when connected to another computer?

Thanks for the reply. I haven't tried it in any other computers and it's only happened a few times over the last couple of months

Could be a connection problem between the drive and USB port. Have you tried a different cable? If there is any data on this drive that you cannot afford to lose back it up as soon as possible to another device even if the drive passed both tests.

Those darn intermittent USB ports just drive me up a wall.  Cables and ports are taking a beating.  Cheap cables and flimsy ports have cost more time and spare parts that it has become the number one fault with external devices of all kinds.  It's nice to have expansion ports but the constant plugging and unplugging loosens the connections and when getting pulled out by the cable, yanked from every angle, does nothing to make it any better.  Cable replacement can solve most issues but will also fail again.  Cheap cables work well where they are installed and left alone with cable strain relief points.

Well it usually stays plugged in all the time so plugging and unplugging isn't (hopefully) an issue with mine. It hasn't happened for over a month now though so fingers crossed it is ok. I'll make sure i backup stuff that i haven't yet though, thanks for your replies!
