can't mount file /home partition

[unessk]

Hello everyone,

I'm a linux newbie, and I have just installed Linux Lite on my netbook.
I have a 250 Gb hard drive, and I tried to keep my data on a /home partition (150gb) that I can't get access too. Linux Lite is installed on another  partition (60 Gb) .

I've tried mounting and unmounting the partition using the command line, but always get a message that the partition can't be mounted, /home is busy, ...

Is there anyway to get access to it without losing any data? Please help ..
