Windows Home Server will be available in both hardware and software form

Posted on By Mark Wilson

In a recent post, I commented on Microsoft’s early indications that Windows Home Server (WHS) will be an OEM-only product – a great shame for many users who would like to put an old PC to use as a home server.  The topic has been raised as a beta feedback request 272635 as well as on the WHS forums and, following Bill Gates’ announcement at WinHEC, it would seem that WHS will be available both as a hardware appliance and in (OEM) software form.  That means that registered system builders will be able to install the software on a customised PC… I’m not sure if that extends to people like myself who intend running WHS on a repurposed PC (a configuration which is now running well with the latest CTP build).  There will also be various ISV-supplied add-ins for protection against viruses and malware, media sharing capabilities, home security, and home automation.

That’s some consolation (I’m sure I will be able to get a system builder copy somehow) but it will also be interesting to hear the price point at which Microsoft intends to pitch WHS.

Struggling with SATA

Posted on By Mark Wilson

One of my PCs includes a Serial ATA (SATA) controller (Silicon Image SiI3112A SATALink – BIOS v4.2.83 and 32-bit Windows driver v1.3.68.0) together with a Seagate ST3500641AS (500GB SATA) disk. Both these devices were added in preparation for installing Windows Home Server (so I haven’t tried them with any other operating system, although I suspect the results would be similar) and I’ve been having trouble with the system’s stability – suffering occasional crashes (sometimes followed by an inability to find the disk) and frequently seeing the following errors in the event log:

Event Type: Error
Event Source: si3112
Event Category: None
Event ID: 9
Date: 13/05/2007
Time: 12:22:25
User: N/A
Computer: servername
Description:
The device, \Device\Scsi\si31121, did not respond within the timeout period.

Event Type: Error
Event Source: Disk
Event Category: None
Event ID: 11
Date: 13/05/2007
Time: 13:54:00
User: N/A
Computer: servername
Description:
The driver detected a controller error on \Device\Harddisk0.

MaplinThe first message doesn’t mean much but following the link from Event Viewer to the Windows Help and Support Center indicated that the disk event ID 11 means IO_ERR_CONTROLLER_ERROR and can be caused by a loose cable. The controller card (bought last week) was supplied with a power cable but not an interface (data) cable, so I bought one at Maplin for £4.99. When I got home I found that the data cable connector housing made the connection too tight against the power cable, making it a slightly incorrect fit (although probably good enough). Armed with this new advice, I set off to buy another cable – this time for £2.99 from a local computer services company… a perfect fit, with a latching connection and less expensive (that’s why it pays to shop locally!). Unfortunately though, this new cable didn’t resolve my disk errors.

Googling the error messages hadn’t turned up much; however searching for the disk model number told me that my disk is actually 3Gbps-capable and that, even though SATA/300 devices should be compatible with SATA/150 controllers, there can be issues with legacy controllers when a technology called spread spectrum clocking (SSC) is enabled. Seagate supplies a utility to enable/disable SSC on their SATA drives bit it won’t run under Windows, so I created an MS-DOS 6.22 boot floppy disk (thanks to bootdisk.com) and ran the utility from MS-DOS. As it happens, SSC was already disabled on my disk but it was worth checking out. Another potential issue is the autonegotiation between SATA/300 and SATA/150 and, following the Seagate SATA troubleshooter, I found this advice:

“Some older 1.5Gbits/sec SATA cards do not support auto negotiation with newer 3.0Gbits/sec drives… Seagate Barracuda 3.0Gbit/sec drives can be forced to 1.5Gbits/sec to allow support with these older SATA cards.

To force the Seagate Barracuda 7200.9 drive to 1.5Gbits/sec mode, apply a jumper to the outer most pins of the jumper block…

This jumper block uses a 2mm jumper. This is the smaller of the standard jumper sizes.”

Seagate knowledge base article 3116

After digging around in my “box of PC bits and bobs”, I found a suitable jumper and applied it; however I followed the diagram in Seagate knowledge base article 2850 (which relates to certain Maxtor SATA drives):

Maxtor Serial ATA jumper options

Instead of this, subtley different one (which I found afterwards in the ST3500641AS Product Manual):

Seagate Barracuda Serial ATA connectors and jumper options

After having applied the jumper to the wrong pins, there were no more disk event ID 11 errors and, as it seems that those pins are for factory use only, I have no idea what they meant; however, after a few hours, I saw the si3112 event ID 9 errors return, so I decided to switch the jumper to the location in the second diagram. I won’t go into the details of what heppened next, suffice to say it resulted in a blue screen of death, followed by a hard disk that no longer spun up and a warranty call… oops!

After receiving a replacement disk, I rebuilt the system (without any jumpers on the hard drive) and confirmed that the errors still occurred with a new disk (ruling out a faulty component as the cause). Then, I shut down the system (always a good idea before performing hardware maintenance) and fitted the jumper to the outermost two pins. Since powering on the computer, there have been no errors, so (fingers crossed), it looks as though the problem was down to a SATA/300 drive and a SATA/150 controller.

I’ve since come across a low-cost SATA controller with an eSATA port, based on a VIA VT6421A chipset (which could actually provide me with some more flexibility – and I can still return the first controller for a refund); however, having got a working driver and hardware combination, I’m reluctant to switch to another chipset (and another set of problems)… maybe that’s something to consider if I experience any more problems later.

If only all warranty calls were like this…

A couple of years ago, I had the misfortune to require warranty support from Dell (a frustrating experience). Then, problems with my IBM ThinkPad left me stuck between a 3-year hardware warranty and a 90-day software warranty. Well, thankfully my recent experiences with HP have been considerably better.

Last year I had some warranty repairs carried out on a couple of my notebook PCs – the warranty cover was for a back-to-base repair: a courier arrived from DHL and packaged the computers, then a few days later they were returned with the faulty components replaced.

Then, yesterday, one of my hard disks failed. I checked the warranty status on the Seagate website (one of the reasons that I use Seagate drives is the 5-year warranty) but it wasn’t valid as the component was originally supplied by HP. So, I called HP, who were happy to take my word that a few whirrs and clunks from the disk, then nothing (except a system that was stuck attempting to boot from drive C: ) meant that this device was broken and needed to be replaced (even if I did have to explain to an overseas call centre operator that I work for a company with 20,000 employees and I couldn’t check every address they had on their system for that company name, but that my home address certainly wouldn’t be there). Half an hour later, HP (or one of their agents) called me to check the part number and promised me a replacement within 24 hours.

By 9:00 this morning, I had a package containing a new drive in my hand (even if the courier didn’t know anything about collecting the faulty component) and a few minutes later I had installed it in my system. By lunchtime, everything was up and running again. Then, I found the instructions that told me to package the failed drive in the box used to ship the new replacement and peel off the label, underneath which was a pre-paid returns label. All that was needed then was a call to UPS to arrange collection and a few minutes ago, the same UPS driver returned to collect the package.

Overall, it was a positive experience (as positive as a wrecked hard drive can be) – less than a day of downtime on a standard parts-only warranty. Thank you HP.
