Dell Inspiron one 19t errors

Hello Everyone,

I have a Dell inpiron 19 touch screen, and it will not reboot do to an inaccessible device at the error recovery screen. I am an amateur as this is the first time I am trying to fix a computer, but this is what I found out. The advanced options did not work and neither did anything else. I ran a diagnostics test, and these are the errors that I got.

Error Code 0146

MSG: Error code 2000-0146

Hard Drive 1- Self test log contains previous error(s)

Error code 0f00: 1344

MSG Disk- Block 211822976: Can't read, replace disk

Drive failed to perform confidence test properly: This may indicate that the drive needs to be replaced

Error code 0f00: 0244

Msg Disk-block 211822976 can't read, replace disk

no additional sense information

Test results fail

Error code 0f00: 0244 ( unless I wrote the same thing twice by accident, this is the same code and msg as previous error above.)

Msg: Disk-Block 211822976: Can't read, replace disk

So I am guessing they are telling me to replace the hard drive, if so, is this the right replacement for this computer? Seagate Barracuda 500 GB Internal hard drive Serial ATA-300 3.5" ... Through entering my set up, I found the GB on my computer to be 500.1 and it says SATA/300

I heard that it was normal to have the .1 GB behind the 500, so I think both of those are correct, and it is a desktop so I am pretty sure it would be 3.5". I also went through a site (can't remember which one)  that has a chart with the correct drives for certain computers, and this seagate Barracuda drive was what showed up for my computer.

The computer no longer has a warranty, and I was wondering if I should go through with replacing the Hard Drive, or try something else. All suggestions and advice will be greatly appreciated, and thanks for your response.
