Computer screen is broken, HP brand.

I have 2 set top boxes the humax is just over warranty all of sudden it wont allow to record or save so i had a portable 1 T hard drive thingy( sorry but this over 50's lady knows almost 0 when it comes to computers ect so im as dumb as i sound) but now all of sudden it showed format- but i didn't yet when i went to its details in settings it said 0.00gb space 0.00gb available which was strange so ran a health check it said good but its wiped the entire 1t of this new portable hard drive. So i need someone to check it & if needed a cheap replacement hdd or what & as im only a pensioner. What i also want is also is if i give ya 2 flash drives so u can download on 1 the latest firmware version updates for the Humax being looked into & if theres a firmware update for Topfield TRF-7160 Quad recording twin tuner set top box. Please keep in mind i dont have a computer at all & that i am only a pensioner so cant afford much but am interested in barter if interested, Oh that's if I have anything to barter with.

I have a 1t Humax set top box and it says 0.00gb storage and i attached a flash drive to record a few shows which worked but after a few it came up saying needs formatting and cleared everything. I ran the health check on it and it says its good but a few days later it did it again. So need new hard drive installed and maybe firmware update. Also do you have pensioner discount at all. Can you please text or email only as i have a talking on phone phobia so please text or email.
