It's unusual that Ubuntu does not see it
How can I access the HDD? PLEASE?
run gparted-pkexec or use the Gparted icon from the Dash
In Puppy linux go to menu /system/GParted
Only look DO NOT do anything else Do Not click anything BUT the X to exit GParted .
There should be at least 1 partition, One called sda or sda1 thats the c\ drive It should be the big grey area saying something like Un Allocated.
Reply here for more Instructions.
In puppy Linux you could also try Pmount Menu/File System/Pmount
If it mounts first thing back up all your documents etc.
Insert a usb stick/HDD into pc open it along side the open My documents folder and drag n drop the folder onto USB.
DO NOT select move the files .......SELECT copy the files then when done confirm the files are in fact on the USB.
Primum non nocere.
