windows 10 "the device is not ready"

I have connected numerous 2.5" and 3" external drives to my pc via USB, and for every drive I receive the "the device is not ready" error message.

I know these drives work, as when installed as internal dives, the system sees them all ok.

I am running:

Windows 10 Pro (activated)

Intel Core i7-4770K CPU @ 3.50GHz

16Gb Ram

64-bit O/S

I have 2 drive letters available.

I have looked at very post I can find relating to this problem and have tried all the recommended tips/answers - all to no avail.

Has anyone found a definitive answer for this problem?

Many thanks,

PeterG

Thank you for your answer.  I have tried all 3 options and nothing has worked.

I should tell you that anything other than a hard disc drive that is connected via USB works fine - i.e. Memory Stick, XD Card, Camera, iPhone, HTC, etc etc.

This only appears to be that disc drives are not recognised, be they 3.5 or 2.5.

Kind regards,

Peter.

Hi, I have now tried hard disc drives from 6 different manufacturers and I get the same result with all of them.  This proves that it is not an external hardware fault.

The only change to my pc recently is the installation of Windows 10 Pro, as an upgrade via the Microsoft Download Site.

I am adverse to going back to Windows 7 and then getting Windows 10 again, as I did this with my other pc, and when I restarted after the new re-install, I was told I needed to buy a licence, and my Windows 10 'expired' as I had no key, as this was also an upgrade.

I have been cleaning and then formatting discs from this pc via a USB cable for years now, and this is the first time I have had any problems.

I am guessing that I am going to have to back-up my data and re-install Windows 10, but I am worried about losing my O/S for a second time.

Kind regards,

Peter.

Hi,

Thank you for the update.

Try to assign drive letter for external drive and check if that helps in resolving the issue.

  • On the desktop, press Windows Key + R to bring up the Run Window

  • In the Run Window, type diskmgmt.msc to bring up the disk management console.

  • Right-click on the entry for the external drive to open the Drive menu.

  • Click “Change Drive Letters and Paths” to open the "Change Drive Letter and Paths" dialog box.

  • Click the “Change” button to display a second dialog box.

  • Click the “Assign the Following Drive Letter” radio button, and then click the corresponding drop-down box to view available drive letters

  • Click the desired drive letter to assign to the external drive, and then click “OK.” A warning message displays.

Hope the information provided helps you in resolving the issue.

Thank you.

No, I am afraid that does not work, as the computer does not show the drives.

I appreciate all your help, but I have decided to re-install windows 7 and then upgrade to windows 10 again

Peter.

Hi,

Thank you for the update.

Since the issue persists, I suggest you to check the same hard drives on a different computer and check if the hard drive gets detected.

If the hard drive is getting detected on another computer, then I suggest you to install the latest driver for USB from the manufacturer website and check if it helps.

If there is no updated drivers available on the computer manufacturer’s website, then download the latest drivers and

try installing it in Windows 8 compatibility mode. Compatibility mode runs the program using settings from a previous version of Windows.

Follow these steps to install the drivers in compatibility mode and check if that helps.

a. Download the driver from the manufacturer’s website.

b. Right-click on the driver setup file and click on ‘properties’.

c. Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 8 operating system from the drop down menu and proceed with the installation. Once this is done, restart the computer and check if the issue persists.

Let us know if you need further assistance. We will be happy to help.

Thank you.
