Dm4 wont boot- hard disk error but passes hard disk test

My dm4 laptop froze yesterday and I was forced to restart it- it is 3 years old but I have had no issues with it. When trying to reboot it will not start and if I run windows repair it comes up with the failed 2 hdd error. I thought it was a hard drive failure as I originally got a 305 error code when running the hard drive test. Upon opening system diagnostics I ran the hard disk test and it passed no problem. However if I run any of the other tests- start up, run in, or system tune up, I get the error Hard Disk 1. I tried the hard disk test again and it passes. Ive run Avg virus scan and found no threats. I have no idea what is going on- I did a BIOS rollback and the computer still wont boot up. What is happening and can I recover my data?

Re: Dm4 wont boot- hard disk error but passes hard disk test

With the intermittent errors,it sounds like the hard drive is failing and will need to be replaced. A retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance if you have a 500GB hdd you could use a 750GB hdd but not a 320GB hdd.


As for whether it is possible to recover your files it depends on how much life is left in the hard drive.Many times you can remove it, attach it to a USB Adapter or install in a USB Enclosure to plug into  working machine via usb port and copy files over to the hard drive of host machine.


If you need more help selecting/replacing the hdd post back with full Model & Product Number as listed on the Service Tag attached to bottom of laptop.

That is what I first suspected but why would it pass the hard drive test if the hard drive has failed?
