 These Maxtor drives may well be flaky, but they are very widely
 available and frequently installed in commodity machines. 

Maxtor drives are flaky?

Oh dear.

How flaky?
Mine is starting to get a bit noisy.

300GIG SATA drives

2005-01-21 Thread Justin L. Boss
Is anyone having problems with SATA drives? I keep getting DMA errors that 
lock up the system.

Could u provide more informations?
I have a SATA raid-1 (160gb disks) on a cheap ataraid controller 
(builtin in an asus a7v880 mobo): no problem at all.

Assuming you are using FreeBSD 5.x then yes, this is a known problem,
there has been some traffic about this issue on this list in recent
months. I filed a pr about a specific case of this a few weeks ago but
it doesn't seem to have progressed.

I have to say I think it is a major problem. It's becoming increasingly
difficult to build FreeBSD machines with up to date commodity PC
motherboards and large storage drives. SATA drives above about 200GB
often seem to suffer from this bug under 5.x, so you need 4.x, which
doesn't work with all up-to-date motherboards. So what do you do?

Peter.

Sorry, yes 5.3R to be exact. I was also informed that this was covered in the 
stable list under the topic Bad Desk. I look, and it pointed to Maxtor desk 
drives as being the problem. And yes I'm using a Maxtor disk. But it 
insinuated in the list that Maxtor large drives quality was bad and it was 
not a problem with FreeBSD OS. But I have installed Linux and NetBSD on the 
same drives without a hitch. I'm beginning to think it may be FreeBSD. Any 
insight would help.

Help, Justin

FreeBSD 4.x also works fine with these drives. I've installed 5.3,
experienced DMA errors, reinstalled exactly the same hardware with 4.10
and had error-free operation. The only OS that fails like this seems to
be FreeBSD 5.x. 

These Maxtor drives may well be flaky, but they are very widely
available and frequently installed in commodity machines. As it stands,
you can't install 5.x on any such machine. Since hardware support in the
4.x branch is lagging, this means you can't use FreeBSD at all on a lot
of computers. Not good.

I'm amazed there hasn't been more noise about this.

Peter.
