I guess I am just looking to confirm the obvious, but it looks like this hard drive needs to be replaced. The reason I am posting the question is, if you look in the last two error messages, each makes reference to a different hard disk. This computer only has one physical hard drive and an external hard drive which is mapped to the letter E:.

Lastly, the computer is setup to allow windows to manage the virtual memory.

The one physical drive could have two or more partitions which could explain why you see more than one drive (at least I think that could happen).

Delayed Write Fail can happen because of a lost of slow network connection (or even USB drive) and does not necessarily condemn the drive.

Do a CHKDSK on the drive but NOT with the /F parameter. That is, do not attempt to fix the drive, just see if it produces errors.

You might first backup anything critical just in case.

I agree, but also add the /r to the checkdisk.  The /f implies to fix error on the disk and the /r will locate bad sectors on the, recover readable information and move that information off of those bad sectors in to non-damaged sectors and make that bad sector as unusable.

chkdsk /f /r

@RSchierer  - I recommend you do NOT run CHKDSK with /F. That will force fixes and has the capacity to change or delete data in its attempt to fix. Run without /F as I suggested earlier to find what (if anything) is wrong before you commit to error correction.

i would advise to:
-backup your data
- run the disk diag  - on a dell you can run them during boot (F11 key?)
-only if the disk passes the diag, run chkdsk - with F option
-another software i used (not free) for recovering drives to a working state, is HDDRegegnerator : http://www.dposoft.net/hdd.html
