Inaccessible Partition During OS Reinstallation

My Acer laptop crashed and won't go beyond the splash screen. The only way I see to this problem is with a clean reinstallation. When I try to delete the primary partition I get:

Error:0x8007045d

- Diagnose and Startup Repair option fail. 

Command Prompt:

X:\Sources>diskpart

After selecting primary disk '0' and followed by clean option I get this error:

DiskPart has encountered an error: "The request could not be performed
because of an I/O device error.
See the System Event Log for more information."

So my disk is inaccessible, but it does exist. What's my next option?

Based on the information given, your problem is most likely that your HDD has failed or is in the process of failing.

The correct solution is to get another HDD and use it instead.
