I have a 2TB hard disk drive connected to my desktop, with a Windows and Ubuntu OS on two partitions of a 250GB SSD. While recently working in Ubuntu while trying write operations onto the 2TB hard disk drive, I am getting the error “No space left on device,” while there is still roughly 500GB left.
Output from df -h:

I am trying to write to /dev/sda1

/dev/sda1 has 492 GB free and using 1% of the inodes.
Sample write operation:
>> echo $PWD
/media/suchet/d-drive
>> touch hello.txt
touch: cannot touch ‘hello.txt’: No space left on device
UPDATE: PANIC MODE!!!
I have lost my 1.5TB of data.
After failing to write to /dev/sda1, I rebooted into Windows to see whats going on. I was able to login safely and actually write a small file to that disk manually. I then rebooted again and tried going into Ubuntu, which complained about mounting error for /dev/sda while starting up. I skipped this message and logged into Ubuntu—and as expected was not able to manually mount /dev/sda—Got an error message about faulty drive.
I rebooted yet again and went to Windows. Upon startup (pre-login) Windows suggested I do a disk check, and I let it do that. The process took about 30-60 seconds and Windows booted up. And My 2TB hard disk drive was wiped out.
Currently attempting to use various data recovery tools on Windows to save my precious work. Most of them seem to recover basic image and document files - but hopefully I stumble upon something that can recover more.
