External HHD is "Unfindable"!

Hello, everyone…

I take photographs - MILLIONS of them. (Yeah, I know!) I ‘happened upon’ a WD HDD, and I just can’t SEE it. The connected noises happen, but nothing… Any ideas? And what’s the UK number for Avast anyway?

Nik - “Millions?”
Here’s 30k: nikwatt.co.uk - I’ve been published locally, nationally, & internationally OVER 60,000 times (all Scotland - unedited!)

Baffles me too as to how it is connected to Avast reads more like promotion of a website (which could be considered spamming).

Are you getting any error or alert from Avast if so what ?
Are you getting any error from Windows, if so what ?
What version of Windows ?

I have a Windows 10 laptop (details in my signature below posts) - I have several SSDs (4 all together) that I use for system and data backups, though no HDDs.

All can be view in windows explorer and I right click on the external drive and have Avast scan it. So windows and Avast can see the the drive and Avast completed the scan successfully.

How this has any connection to the use of AVAST baffles me. We don’t even know whether the HDD is a new one or if it has the “millions” of photographs mentioned and has just suddenly stopped being recognised.

However, to be helpful, I’d suggest doing this:-

and checking whether the external HDD is seen there and, if new, initialized. If it is not then I’d try the HDD using a different external housing connection and if that doesn’t work I’d suspect a problem with the HDD itself.

How do you know this is Avast related?
