[mythtv-users] OT: Can IDE and SCSI mix?

[Mike Isely]

I currently have a 2.6.9-ac14 system running this very minute with:

3 IDE hard drives
1 SATA hard drive
1 Numerous SCSI devices hosted from an old Adaptec AHA3940 controller

And it's running mythtv too (as my test box).

Though that system doesn't strictly have a _real_ SCSI drive in it, I too
have in the past freely mixed SCSI and (parallel) IDE hard drives all the
way back at least to the 2.2 kernel series without ever encountering any
problems.

Note that SATA drives also use the SCSI layer so even though they're IDE
by "heritage" they operate as SCSI in Linux.  My SATA drive shows up as
/dev/sda1.

So I second Lonnie's conclusion doubting any potential problems.
