checkdisk will only check one drive

[lcyber]

I am trying to run chkdsk/f in my D drive but it will only recognise the E drive(I don't have a C drive)
How can I check all the drives?

If your os is on the D drive you need to unmount it first. Use the /X switch. the sysntax would be: chkdsk D: /f /x

I don't remember if the system prompts you to restart or not. But at the next bootup chkdsk should run prior to loading the os.

I have a feeling the os is on the E drive,how can I establish which drive it's on?

Try this.
Use chkdsk /r D:
Make sure there is a space between chkdsk and /r.
If it is the system drive,it should give you a notification about
scheduling to run on next reboot.

It shows as an invalid perameter so I guess the os is on E drive,does it "need" to be on this particular drive as before I had hard drive trouble,I didn't have an E drive.I take it there must be some advantage in putting it on this drive.How would I then check the D drive, if it doesn't have the os on it?
I have already run chkdsk/f on my E drive with the os system on it and I would now like to check the other drive.
