I recently downloaded and mounted a 15.2 Hiren Boot CD, all the drives attached to my MOBO are in AHCI, however the CD just detects the 2 TB HDD and doesn't detect the SSD, both drives are on AHCI mode. Is there any reasonable explanation for this?
I use the CD to boot Mini XP to access drives if any failure happen.
What are the specs for your system? It could be that your SSD in connected to a non-native SATA port (like a Marvell port instead of an Intel or AMD "native" port). If so, the necessary drivers are likely not on Hirens.
