SSD detected as HDD

Recommended Posts

Hello; In Defraggler I have a SSD that is being detected as a HDD.

I believe this is because of the Intel Smart Response/ Intel Rapid Storage / Intel Rapid Start technologies present on my system.  Before I made these changes Defraggler was able to correctly identify this SSD as a SSD.


The way the system is configured is with the SSD and HDD in a simple raid array (it would function as a spanning array; as in the data is temporary located on the SSD before moving onto the HDD).  

  • The SSD uses a 64gb partition to accelerate the associated 500gb HDD to support Smart Response.
  • A 16gb partition on the SSD is used as a Hibernation Volume to support Rapid Start.
  • A 175gb partition (this is detected as a HDD instead of the SSD) has the operating system and such on it.
  • And finally there are a few partitions summing up to ~1gb to support the UEFI system.

To sum that up in a Defraggler view:

Drive    | Media Type | Capacity | Notes
SSD (C:) | HDD (NTFS) | 158.0 GB | This should be detected as a SSD.  It is a partition fully housed on a SSD.
HHD (D:) | HDD (NTFS) | 465.8 GB | This is correct.
RDD (R:) | HDD (NTFS) |   2.0 GB | This is actually a RAM Drive linked to folders on the SSD.
Recovery | HDD (NTFS) | 300.0 MB | This is actually a partition on the SSD used by Windows / UEFI.

So; is there a way to 'force' Defraggler into treating these volumes correctly?  With them not being classified as SSDs I am unable to use the Optimize Function; and of course it tries to defrag them as it would a HDD which will lower the drive's life.

Thank you in advance!



HDD: Samsung HD501LJ

I think you might be onto something, I wouldn't say because but certainly seems related.


Windows identifies the drives correctly in Windows Defrag (dfrgui.exe):

  • Kingston SV300S37A120G SSD (C:, D:) - Solid state drive
  • SoftPerfect RAMDisk (R:) - Unknown

where Defraggler identifies them all as HDD.


Using Intel Rapid Storage just for the SATA driver (Intel Chipset SATA RAID Controller,

I believe I've seen this problem with Defraggler unable to indetify the disk types before with Windows 8.1 and now with Windows 10.


Closing and reopening Defraggler never fixed it for me.

Just created an account to say this.



I have the exact same symptoms as DanDar3 (although I'm not using Intel anything). Windows' build in defragmenter recognizes my SSD as an SSD, but Defraggler thinks it's an HDD.



Is there any fix or a way to force Defraggler into thinking my SSD is actually an SSD?


It's a bit irritating that I'm missing out on some features and that Defraggler wants to defrag my SSD...
