Windows 7: SSD fast alone, slow with HDD

19 Jul 2012   #1

Windows 7 Home Premium 64
SSD fast alone, slow with HDD

So I have a Windows 7 64 with an SSD and a HDD as a data drive.
I reinstalled fresh Windows 7 onto the SSD and things are very fast.
Once things were working as they should I connect my old HDD, jumped into the BIOS to set it as the second drive and started up. It was SLOW. It is slower than the same machine before I put in the SSD.
I formatted the HDD and restarted with no improvement. I have tried it with BIOS setting disabling the second drive still slow.
Here is the weird thing, if I disconnect the HDD it is fast again. All scans on HDD show it is all good.
BIOS is set up with AHCI
BIOS has SSD as first boot-up drive
BIOS disabling the HDD or Enabling does not help
During safe mode, it hangs up on CLASSPNP.SYS for 60-90 seconds.
What do you think??????????????
