system diagnose error

[mars1957]

after many failures to upgrade from windows 7 home premium 64 bit to windows 10,  i decided to make a clen install of windows 10. although the system is running once the boot is complete, but the bootup takes almost 1 hour to finish. i tried to make a system diagnose while booting, i receive the error (9LLDU4-55985L-XD6U3G-60QJ03).

do you have an idea on what is going on

thanks for your help

Hi,

The 24 character error code is a failure of the short Disk Self Test ( DST ) and would indicate that the Hard Drive is failing and needs to be replaced.  This is also consistent with the slow boot issue you describe.

If you would like a guide on replacing the Hard Drive yourself, please let me know - include the full Model No. and Product No. of your dm4 series notebook - see Here for a further explanation.

Hi,

You're welcome

Your notebook is listed as coming with a 320Gb Hard Drive, but you can just as easily install a 500Gb or 750Gb HDD if you want a bit more space - the drives on the following links are examples that would be fine for your notebook.

500Gb Hard Drive

750Gb Hard Drive.

The procedure to replace the Hard Drive starts on Page 61 of your Maintenance & Service Guide.
