I have a Toshiba Satellite laptop with a possibly dead toshiba HDD (ATA I believe)

I want to know if there is a diagnostic to test whether my drive is done for

Here are the details of what I have tried.

First thing first, My mom said she dropped the laptop while it was on & the laptop would no longer boot into windows.
None of the window's or toshiba recovery tools worked.

I used ubuntu live CD and was able to transfer most important stuff onto portable HDD. Some files would take a long time to copy only to show up as a corrupt file on my portable HDD.

So then I decide to install this ubuntu. I let ubuntu use the entire drive under the partition option.
All seems good, the OS installs and reboots. I mess around with the ubuntu features a bit, update, shutdown and go to sleep.

the next morning i wake up boot up the laptop and it loads into ubuntu only it is unresponsive. the LED light of the HDD on my laptop stays solid blue.
For what's it's worth something like this would come up on my screen :
"[ 59.517457] ata3.00: status: { DRDY ERR }
[ 59.517504] ata3.00: error: { UNC }
[ 59.702599] end_request: I/O error, dev sda, sector 106645428"

im thinking the OS is having a trouble over a section (sector?) of the HDD. So i read about this SMART technology built onto HDD and diagnostic tools, only to find out toshiba decides not to provide one. Other people claim success using hitachi IBM and such other's diagnostic tools but none worked for me. I would always get "not so & so company cannot continue"

I came across ultimate boot CD and finally i get something to work for my toshiba drive. It is ViVard, under the ultimate boot CD. Gave me an option to test physical and remap errors. Currently it is going at 267 errors with 267 remaps at 3% completion. Most errors are UNC and AMNF, whatever that means.

What can I do to test if my hard drive is still good?
Maybe I should just get a new one

It was dropped and now has a bunch of bad sectors. Time for a new one, for sure

Yeah I figured, I canceled the scan said it would take 53 hours

Now I'm looking to purchase a new hard drive
