[Update] Intel G33 motherboard's AHCI not detecting hard disks
Original thread: https://groups.google.com/forum/#!to...lt/OayrOg7rlAw I attached a Western Digital Cavier Blue 500G hard disk (WD5000AAKS-65TMA0) to the same motherboard. AHCI worked faultlessly. So the problem was the Seagate 7200.10 250G SATA hard disk (ST3250620AS). SATA modes should be standard among all hardware devices....I still could not be sure whether it's a motherboard problem or not. -- @~@ Remain silent.

SATA modes should be standard among all hardware devices....I still could not be sure whether it's a motherboard problem or not. I thought AHCI had fallback behavior, if a device didn't properly support some part of the AHCI standard. For example, Raptors (various generations) have TCQ and NCQ. And NCQ is a part of AHCI. If you plugged an old (TCQ) Raptor into AHCI, and Windows sees only TCQ, it should just disable the tagged queuing portion and continue normal (IDE like) operation. It would still claim to be following the AHCI standard, and perhaps things like Hot Plug would still work - it just wouldn't queue up commands for completion out of order. http://en.wikipedia.org/wiki/Western_Digital_Raptor So I don't know what your Seagate drive is doing in this case. On page two, the Seagate drive does list NCQ support. http://www.seagate.com/docs/pdf/data...da_7200_10.pdf The BIOS doesn't need to use AHCI when the system starts up. AHCI operation starts when the OS driver loads, and control is transferred to the OS. The BIOS would not be using command queuing for example, because it isn't necessary. Command queuing helps, when there is an outstanding series of requests queued up. And the BIOS tends to be single threaded (at least the legacy BIOS is, don't know about UEFI though). Another avenue to explore, is see what the BIOS tables report for the hard drive. The BIOS passes a series of tables, for plug and play usage. While Windows has some "direct" probes it can use for plug and play (VID/PID or VEN/DEV), the BIOS tables label things with convenient generic labels, and that can also trigger the correct response from Windows detection. An example of that, is generic "Class Codes" used for hardware detection. You can go to Device Manager, do Properties on an entry, use Details tab, then "Hardware Ids" to see more info. I don't use AHCI on my computer right now, and when I use Device Manager and look at the Hardware ID, it reports "PNP0600", which is presumably a value coming from a BIOS table. The value 197b-2368 is the VEN/DEV coming from the chipset, and is also in the hardware ID list. I don't have enough hardware here, to give you some representative values for what to expect. I'd have to switch to AHCI mode on my current computer, and install an OS to do some testing. Which would take me half the day, and take me offline :-) Paul |

Really. 250 and 500G HDs are way back in dating 1 & 2T drives;- we're on 3T presently. Any, even if an older MB shouldn't have problems in that storage range. I've also Seagate 250/200G HDs, mixed variously with WD and Samsung HDs, ranging from 850G to 2T. I don't believe in the newer HD ranges, though, I've any partitions larger than 1T, which I generally format from docking stations prior to installing on either MB, which I believe would be both Gigabyte boards. On one of the larger HDs, I run it from a $15/US, 2 SATA port, PCI controller. Not saying everything is perfect, there are a couple of oddities, (for instance, have a defragger that balks at slow speeds on the PCI controller, whereas a file copy runs fine at expected speeds), nor do I particularly necessarily trust those MB and their ages with all the latest and greatest, especially when looking at 2T drives. I'll also make one of those older 250/200G drives a main boot disk before using a bigger HD for other than storage. The boot function, however, may be superceded with the next 128G SSD I see onsale for $60 (well made 64G SSD's are pretty damn hard to find for $40). Like I said, a $15 SATA controller is another comparatively cheap testing route if that MB is picking up some drives while not others. Not fun when HD storage is in jeopardy, nor a new MB/system build when a MB rarely, especially an Intel MB, turns to the radical side. Hope you find a relatively easy fix to your satisfaction. |

Divide up some primary partitions for a few operating systems, a little storage for the rest. Only problem is it's nice to keep it down to 2 spinning HDs, over three - less clutter, heat, peak or constant power draws. Unless one is a SSD, which doesn't use resources though doesn't then give a 250G much function. I also at one point was angling a SSD boot-installed arbitrator, defined to boot from the 250. I was having trouble getting the MD/SSD combo to boot from the SSD's partitions, though eventually "fixed" it in my own way. Its boot arbitrator is not setup the same as a spinning platter install, nor am I exactly sure why it works;- Been awhile and I've half forgotten how I did it, too. (Wasn't supposed to work, what I attempted though managed, I read, that my MB support for a SSD wasn't within current specs.) |

Heh - it's a gigabyte LGA with an the early first dual pentium, rather than psudo hypthreading CPU intel once was foisting for dual cores. 4 or 5 years easy befor SSDs. LGA is a nightmare if you ever bend a pin on the MB. I did. I fixed it, too, but it's like writing on a rice kernel with a fine sewing needle. Which is what I used, needle and a dispensible razor blade. I was doing the actual Intel bending under a powerful lighted magnifier (probably around x20 or x25). Myth of course would have some LGA masters doing it blindfolded in their sleep. |
