My second drive (the Drive) is running but it doesn't show in any of the file explorer files and nothing happens when I try to restart my pc in order to get it back. I got this message before: 'D is not accessible.'
Hi, see what happens with a 3rd party partition manager e.g. Minitool Partition Wizard.
Post a screenshot of what you see.
Get a copy of Hard Disk Sentinel (trial, portable version also available) - run that and post a screenshot of what it says- if it can access your drive.
History (so often omitted by posters)
When was this drive last accessible?
About how old is it?
Had you been having any problems with it?
Do you have a full backup of its content?
1. I have had this secondary drive since last year.
2. It was last accessible earlier today and I had just fixed the My Documents file.
Run the following script and post the output:
DiskParInfo.bat
Source: Batch files for use in BSOD debugging (provided by the BSOD team)
We need to see the full output of diskpartinfo.bat:
