ssd slowing down hdd?

i had just recently bought a Samsung 840 evo 250gb SSD,
and after installing the windows on it,
my old HDD became very very slow when reading,
and the computer boot time took longer than before when just using the HDD.

my SSD is working fine,
reading and writing with excellent speed.
And if unplugged the HDD,
the boot time will also run fast as it's supposed to be as a SSD.

I tried checking error for drive, and it seems to run faster.
But once i restarted PC, it went back to the same slow speed again.

  1. Check your BIOS. Make sure boot priority is given to the Samsung EVO. Make sure it's first so the PC doesnt spend time looking for other drives. That's what I did to my EVO. Although I never had slow HDD problems...
  2. I bet you're booting to the HDD by mistake. Like AzisTroyanov, make sure that you're boot priority in BIOS is set correctly.
  3. Agreed
  4. Boot priority is already given to Samsung Evo,
    And i don't even boot the HDD at all.

    the only thing i haven't tried yet is format the hdd...

    Then that's it. Windows may see some files on the HDD and still attempt to use that drive. Its good to format it if your going to be using it strictly as storage, like I did.
  6. ok seems like i fixed twice,
    and there's still this in event log.

    "The device, \Device\Harddisk1\DR1, has a bad block."

    So, should i bother to format at all?
    or the HDD is no good at all already.

    edit:
    WDC WD10EADS-00P8B0 ATA Device
    is from what manufacturer?
    Maybe i will download their official diagnostic tool and try one last time before deciding getting a new HDD or not.

    I typed that in google and it shows as a Western Digital "Green" drive. So there you go.

    It says "Bad block" because the drive may be going bad. So its probably a good idea to back up your data, format your drive, and see how it goes. If it still is having issues, then your drive is going bad.

    The slow startup may be from the defective drive. I actually had the same issue once. I plugged in a dying laptop drive into my sata port and was wondering why my computer was so slow. I never formatted it, but I did find out the drive was dead by the experts at Frys.
