HELP!

I have a VU+ Ultimo 4K
I've had the machine & HDD for nearly 6 years
I have a 2.00 TB HDD (25% was free space)
I believe that I am running VIX 6.0 but I now have trouble finding information.
I've disconnected 2 USB external drives that I store media files on.

I started to get failed recordings and the message 'Write error while recording. Disk full?'

I tried a reboot several times but again failed with later timer recordings.

Looked on here for similar and then tried to mount

'Blue button - ViX - Mount Manager - green button'

It is showing
HDD: ST2000LM015-2E81
Size 2.00TB
Mount: /media/hdd
Device: /dev/sda1
Type: ext4 R/W

Tried this a few times but again no luck and eventually sometimes I cannot see any files or recordings or structure on the HDD, No files or directory will open without bombing the machine.


If I do System -> Storage Devices - Filesystem check then;

Checking File system ...
Error: e2fsck -b 32768 <device>
fsck.ext4: Input/output error while trying to open /dev/sda1


Sorry I cannot remember how to copy the log file onto this post

Am I going to have to reformat the drive and lose all the recording on the drive?
Should a try a software update to 6.2 from a USB stick?
