File permissions changed by themselves?

Hi,

I went to made a new virtual box on a drive which was recently convertde to go from several partitions to just one, and although I can read files I cannot delete them or indeed write a new file to the drive. Not sure how this has come about. How can I get it back to normal? The username of the host is 'home' and the files are as per screenshot given read/write permission? I think I am pretty sure I did this in linux gparted, I remember writing a post on here complaining how it moved all the data which took hours rather than simply expand the partition to the start of the drive.

It can be permissions too. Logs are generally a good place to start such as dmesg for if the drive mounting is having issues. I'd look at how the partition is mounted rw vs r or other

I'm starting to tear my hair out now, yesterday this drives partition worked fine and now today it has the attached error message saying I/O error, this is nonsense because the other partition on the same HDD is accessible. I was under the impression I/O error messages were hardcore disconnection issues. How do I check what is going wrong? I tried error checking with gparted it gave error on access, tried unmounting and mounting again same error.

FSTAB for Data drive is th following, Data is the first partition roughly halve the disk, DATA32 is the FAT 32 partition on the second part of the HDD.

UUID=1FDA1CEB6049CD2A /mnt/1FDA1CEB6049CD2A ntfs-3g nosuid,nodev,nofail,umask=000,rw 0 0

Now it seems I have access back but it shows as empty in Thunar file manager and it says it has 6.8gb spce which is not true, none of the drives or drive partitions are 6.8gb. Furthermore in gparted you can see 60gb is used on sda2 so clearly it is not empty. This is baffling.

If it's not showing in the file manager it's probably not mounted. You'd have to look in dmesg for the reason

Thank you for your heklp may I ask what dmseg is? I am not familiar with that command, the fdisk program said it was mounted and the thunar file manager shouldnt be sowing the drive at all if its not mounted surely? Plus where did 6.8gb come from??

The plot thickens, I went into winows 10 and this is how it shows the drive, it only sees the NTFS drive DATA and does not show the FAT32 drive DATA32. Furthermore it sees the NTFS drive as taking up all the space of the 500gb drive and not half of it that Linux reports. Well I think I will backup my stuff not already backed up, wipe the drive and start all over. What do you guys think?
