Re: [PATCH libata-dev-2.6] Issue INITIALIZE DEVICE PARAMETERS for CHS only devices

quoted

It has been about a decade, but my memory vaguely suggests
that I tried that once before, and some LBA-capable drives
still required the IDP before they would function normally.

I think anything ATA-4 or later was fine, though.

So..

if (ATA < 4 || !lba_capable)
     issue IDP command
else
     no need for IDP command


Cheers
