Windows 10: Portable HDD intermittently not recognised by W10

I am having a lot of trouble with a Toshiba 2TB portable HDD on Windows 10. Sometimes it is recognised by Explorer, sometimes it isn't, and I can't discern a pattern. The drive works in every other device I have, and when it doesn't work, it is not seen using any of the USB ports. It is not a case of a duplicate drive letter; when it fails to be seen, it isn't seen in Device Manager or Disk Management either. There is always power to the drive, as even when it fails to be seen, it lights up blue for USB3.

One pattern I do notice is that, when the drive fails to be seen in Windows 10, the subsequent restart or shutdown can take up to 10 minutes. Even after that, there is no guarantee that the drive will be seen.

I guess this suggests a driver failure of some kind, but I thought I would ask.

Thanks!

Portable HDD full but isn`t..

Hi Graham,

In most cases, this may already point to a hardware issue. We suggest doing the following to properly isolate this:

• Connect your portable HDD to a different port.
• Connect your portable HDD to a different PC.
• Connect other storage devices.

If you find that other storage devices work properly and your portable HDD still encounters an error with other computers, then this is already a hardware issue and you'll need to get in touch with the device manufacturer for assistance and troubleshooting.

Feel free to post back if you need more help.

 

Not recognising HDD

I recently updated to Windows 10 Anniversary Update, when I put my computer to sleep when it wakes up it does not recognise my Toshiba HDD. I run my OS and main programs off my Samsung SDD but my documents, music, photos etc. are on my other HDD which is
not being recognised by my computer. After I restart my computer it shows up again, but if were to put it to sleep again, it would not appear.

When it is not showing up in "my computer" it is also not appearing on device manager.

Suggestions?

 

Portable HDD and pens not recognised in USB ports


I have a 2 year old CIT cobra case and have always had varying issues with portable HDD's and USB pens being recognised don't have any issues with the rear USB ports...one USB pen actually changed its contents partly to what was on it before I formatted it....

I am reluctant to accept that it may be a hardware fault, but beginning to think it must be.

I don't know if CIT cases are well made, or if this is unusual.

I am looking at replacing the case, possibly with a ZALMAN Z11 Plus Midi Tower Computer Case, particularly as it has room for 5 internal HDD's, which I need..

wonder if I have any other options and am I going the right route

thanks
