Re: hard error reading: set fstab mounts to frw: can no longer access filesystem
I am using FreeBSD-4.10, how do I boot it in single user mode? -Ed On 3/21/06, Derek Ragona [EMAIL PROTECTED] wrote: Edwin, Boot the server single user, -s.

Re: Replacement hard drives, was: Re: Hard error??
the new Seagate 120gb seems to be real quiet and stable for me I cant even hear it running, they have a new motor design and probably is the best bang for the buck right now about $140.00 I had bad luck with quantum, maxtor and IBM and WD but Seagate seem to be very good for me right now.

Re: Hard error??
I used to get this error on a FreeBSD while using a perfectly stable harddrive. That harddrive is managed via Solaris now, but, I determined the issue during its FreeBSD usage was DMA. If you are running two disks on the same ATA channel with different DMA capabilities, the capabilities may be causing scrambles in the negotiation of I/O on the line. The solution is to put ATA drives that use _only_ the same DMA caps on the same ATA channel. If you only have two drives, simply put ATA0.1 on ATA1.0. This stopped my falling back to PIO messages and probably saved the disk from hard failure caused by misuse.

Its entirely possible, but, I, personally, wouldn't know for sure.
I'm just getting in to the depths of the ATA specs. It may not be
a bug so much as a lack of handling specific DMA issues.

First off, I've been using Maxtor disks the most since I started out in computers and haven't had one fail yet (running every OS i've tested). Now that I'm alittle more experienced, I use Maxtor because of its standing credibility with me, and, because the Chairman of the T13[1] (technical committee for ATA[-ATAPI] development) is from Maxtor Corporation. They are most likely to want to adhere to a published specification (along with other T13 members), rather than develop chipsets that are rushed to keep up with a $25 billion a year industry.
