Touro Mobile 3.0 - 1TB not recognised

[Chris York]

I use a 1TB Touro Mobile 3.0 external hard drive with my HP 250 laptop. Both are around 3 years old and have worked perfectly together to date. The laptop is now running Win 8.1 fully updated.

Today the Touro is being incompletely recognised. It appears in device manager and in Devices. But fails to appear in File Explorer. When you look at the Touro Mobile 3.0 Properties it offers three hardware function options - Touro, HGST USB Device and USB Mass Storage Device.

Touro/Properties/Events lists in ascending order, Device Installed, Driver Service Added, Device Not Migrated, Device Install Requested. That looks incomplete to me....

HGST USB Device/Properties/Volumes shows blank but populates OK. Opening a second time again shows blank.

HGST USB Device and USB mass storage device both show started, configured, migrated in Events, which looks right.

Any suggestions as to how to proceed from their?

Hi there Chris York,

This is really unpleasant.
Do you have some important data stored on it? I believe the drive is no longer under warranty right?

One thing you can start with is to just attach the drive with a different cable to another system.
If the issue persists, you need to go to Disk Management and whether and how the drive appears over there.

In case it has damaged partitions and/or file system, you will need to use some data recovery tool in order to retrieve the data: http://www.tomshardware.co.uk/forum/id-1644496/lost-data-recovery.html
After that, you can check the drive's health status out with some of these: http://www.tomshardware.co.uk/forum/282651-32-best-diagnostic-testing-utility
Observe the SMART report and look for reallocated/pending and uncorrectable sectors.

If the drive is not recognized by Disk Management and you've tried using a different cable, then there is something wrong with the enclosure or the HDD itself.
In that case, your safest bet for recovering your data would be to contact a data recovery company.
Some users attempt to take out of the enclosure in similar cases, in order to attach the drive internally or externally. Yet, keep in mind that this may not work due to various reasons: hardware encryption, proprietary connectors, etc.

Let me know how this goes,
