I've been using my external HDD on my laptop for ages and wanted to check its contents on my PC but it does not appear in This PC  but when I go to Safely Remove in the System Tray it is there.

 

Any explanation please - thanks.

1) Start - Run - Diskmgmt.msc

Does the drive show there? If not, try it with another computer to see if it is recognized. If it isn't, the drive may have failed.

Thanks for responding.

 

Yes it shows on my laptop and even on my netbook and can work on it. All computers on Win 10. It's strange that on the PC it shows on Remove Safely in the System tray and doing this the HDD switches off OK.

I'm sorry, I don't see your response to whether or not it show in disk management?

Disk management does show the external drive but oddly as I plugged it into another USB socket it does not show in 'Safely remove..' at all so can't do that!

 

So it seems that there is no way to view my files on this PC.

Let's go back to disk management. Can you upload a screenshot please.

The 4 TB is of course my external HDD and the 2GB is a SD card.

It looks like you need to assign a drive letter to the disk.  The OS of the computer is not XP 32bit, correct?

 

Here is a guide. Press Add.

Mmm - perhaps this is it altho my PC, laptop and netbook are all Win 10 and it shows up on the last two OK.

 

Actually I never use that HDD on my PC, just once to check for a single file so I'll do a change a drive letter if needed - thanks for that tip - that must be the cause as I have never assigned a letter to it, just to use it to load my VHS tapes on it with a video capture gizmo which the laptop can handle but not the PC.

 

A few minutes ago I got a Windows update message and did that. Now both the HDD and the SD card are in the 'Remove safely...' but the HDD not in 'This PC' as before.

 

Thank you for your attention on my glitch, much appreciated.

From your image of Disk Management it doesn't look like XP but XP 32bit cannot detect a GPT disk which is what your 4TB drive is.

This PC used to be XP but has gone thru Win 7 and now Win 10 - would DM still think it is on XP,  some kind of residual memory?

 

The netbook was XP though and is older than the PC.

 

Rather curious.

No on the first question. If you updated from XP then the drive should be detected so I surmise it only needs a drive letter assigned in order to be detected.

Agreed - assign a drive letter and let's see what happens.

Oh dear, very sorry,  I have had  a brain glitch - that external drive always had a drive letter from when I first used it namely E. When using the video capture it needs a drive letter to know what the destination is. It didn't show up in the Disk Management did it - why not?

 

So it's back to square one.

 

Just done a DM using my laptop and the drive letter E is there so it must have to do something with my PC.
