Hi there and welcome
Can you tell me please which version of windows you are using? Or is this a mac computer?
If you plug it into a different USB port on the computer, is it then detected?
If you connect it to a different computer, is it then detected?
ok, it means the data is corrupted on it. Do you have data you need to keep on it?
ok, if there is no data on the drive you need, then format it when asked, then it should now be usable.
Let me know the results please.
If you connect it on your wifes computer, it is being detected correct right?
ok, connect it to problem computer.
Then click start, computer on it.
Click in the new window on computer and tell me if you see it there listed where you see C Drive ect
ok, so it is connected and working, it is then the software thats at issue.
Can you go to Start, Control Panel, uninstall a Program and uninstall the backup software
Restart the computer, install the software again and then try to perform a backup.
No, just return to this web page please and post a message.
yes please, and also when installing it.
Connect it when it requests this please, like you did when initially installing it.
install the software on your wifes computer and tell me if it detects it there please.
ok, than do the following please
Download CC Cleaner (free) from here
(Click Download Latest Version on the top right)
Run it and let it scan and repair your registry.
Once done, restart the computer
Click Start, Run and type in CMD and press enter
A black window will open.
Type in it
press enter and when it has completed, type in
It will give a message "the type of the file system is NTFS cannot lock current drive.
chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts y/n" Say Y, press enter and restart the computer.
Then tell me if the software then detects it please.
yes, the computer with the problem.
yes that is no problem, until then.
Ok, then last step left is a reinstall of windows as we have attempted all possible repairs.
Can you backup all data off the computer please (as it will wipe all data, programs you will have to install again) and then tell me the make and model of the computer
No that wont help as the disk works, but you can just copy and paste files to it via file explorer
issues on the computer which we have tried to repair but has failed.
Ok, you copy them like any other files on the computer
So right click the file or folder and select copy
Then go to the Drive and then again right click and select paste.
yes, as you indicated it is accessible on the computer, it is just not being seen but the software.
Let me know please if you get stuck
