Yes, a workaround is to set BIOS to use IDE not AHCI but isn't AHCI better than IDE? Hot-plug, queuing, etc. Specillay if you have a e-SATA port.

Is it safe to hot-plug in IDE mode?
Is performance better in AHCI mode?
Why it is so problematic to include the AHCI driver compiled into the kernel?

Fortunately, I only reboot this computer from time to time :)
