Inspiron 1501- Error Codes 4E0F:075D & 4E0F:1A44

Before posting this I have scooted around the internet & this forum looking for answers, I think I have it, but as a non-techy I need some re-assurance.

Laptop suddenly stopped booting up, does Dell splash screen, Windows Boot up screen, Advanced Options Screen on an eternal loop. Ran a full diagnostic last night, and got these two messages;

Error Code 4E0F:075D IDE Device failed  The self test failed the read portion of the test

Error Code 4E0F:1A44 Block 120362075 uncorrectable data error or media is write protected

I presume the hard drive has bad sectors and they have spread causing the hard drive to fail completely?

I also presume that no data is recoverable from the disk?

Any help/advice/therapy gratefully received! :emotion-1:
