IDE Harddrives Detected as SCSI?

[1stFlight]

Okay now this is odd, XP detects my EIDE hard drives as SCSI. It doesn't seem to be a problem at all, haven't done any benchmarks to see, but it's a bit odd, anyone else run into this?

Known nForce2 thingy. Don't install the IDE drivers, methinks, and they won't appear as SCSI.

Somebody else tell him, I don't have an nForce2 board ;)

[Matthyahuw]

yep, say no to nForce2 IDE drivers...

[elusive]

you guys sure as hell don't know much about windows.

it will detect it as scsi.

don't worry about it.

it's NT kernal.

Erm, no, it's a bug in the nForce2 IDE driver. Or it's a feature, I'm not really sure. But either way, I'm running Via IDE drivers and its not being detected as SCSI, another box is running SiS IDE drivers and those drives aren't being detected as SCSI, and laptops.. well, they're NEVER detected as SCSI.

So you, my friend, win the Full of Crap Award of the Day.

2k sees my Promise Ultra 66 as scsi and it certainly isn't.

hey Baron, don't be mean, I made that mistake before.

Apparently there're SCSI miniports and IDE miniports now, and I didn't know that before.

Not exactly. The NT kernel does not detect IDE drives as SCSCI. When one type of drive is detected as another, that tells you something is wrong. As for my knowledge on the NT kernel? Well I know enough to have passed the A+ OS Exam, which deals quite a bit with that kernel, so my knowledge is legit.

It sees your drive controller as a SCSI controller, sure, but it doesn't see the drives as SCSI. At least I don't think it does--never used a Promise card on Win2k and the box where I could VNC to check is currently being used for an all-night paperwork session.

Oh well, though, not really important. Matrix Reloaded trailer, on the other hand... :D

You can use a SCSI miniport for IDE, though it isn't recommended, and that will happen. I had this happen on earlier Via drivers, which led to my initial confusion, but someone corrected me when this issue came up...

at any rate, yeah. blame VIA!!! <goes away now>

VIA ? :confused: but he have Nforce2 :p

I don't see the big deal, one of my other computers has a PCI ata/100 card on a 440bx board, and windows considers it a SCSI controller when it isn't,, but who cares it works fine. It can call it Peas&Carrots as long as it works.

My advice: yes DO install the latest drivers from Nvidia, and as long as the system seems stable then just live with it and maybe they'll revise the the name in the device manager in future driver release. Because afterall we're just talking about a name here me thinks :rolleyes: ;)

Every IDE RAID controller I've owned has been detected as a SCSI device, as well as the SATA controller on my Asus nF2 motherboard now too. The current nVidia drivers install the nF2 IDE as a SCSI controller if you only do the normal install routine too. There is a way to install a driver that is still recognized as an IDE controller (I did this), but I don't personally recommend it. I had no end of weird problems while using the nForce2 IDE drivers (whether recognized as SCSI controllers or not), ranging from things as minor as being very slow all the way to system lockups while in my games. I've since reverted to the Standard PCI Dual IDE controller that came with Windows XP Pro, and all seems well. Supposedly nVidia is doing a complete from-scratch rewrite of their IDE drivers to address known issues.

As far as the drives being seen as IDE or SCSI, that is directly related to what the controller they're connected to is being seen as. Example: I have my primary hard disk on the nF2 IDE, and a pair of IBM 60 giggers on my Promise PCI IDE RAID controller. Now that I'm using the standard WinXP Pro IDE driver for the nF2 controller, the main drive properties show me all the standard options available for IDE drives. On the other hand, the IBM drives have the options that XP usually provides for SCSI devices (disconnect, etc.). While I was using the nF2 IDE driver nVidia provided that causes the controller to be seen as a SCSI device, my primary drive only had the SCSI-appropriate options in the device manager.

As a consequence, about the only real downside to having an IDE drive seen as a SCSI device is that you lose some configurability / verification of settings capabilities. Ie.- you can't make sure that the drive is running in the right DMA mode, you can't disable write caching, etc., for it as SCSI, while both are available when it's seen as an IDE device (DMA mode settings are actually available under the controller hardware entry for IDE controllers, while the write caching option is directly under the hdd's properties).

The thing about the NV drivers is I think they'll be fixed up nicely in the next driver pack, SCSI or no. every time I've gotten a pack from them I've been impressed. Yes, the bugs that show up are annoying, but they do fix them up nicely. Last info I had said they're working on both a newer SCSI miniport for XP and a IDE miniport for 2K/XP

About the Via comment, I was talking about my previous experience, not the current topic really.

No it sees the drive as scsi as well.

As for the Matrix Reloaded... I might go see it, so I can see the Return of the King trailer. Not really interested in the movie. :D

I think that this link from the Microsoft Knowledge base will clear up some confusion about NT 4.0 and Windows 2k /XP. ( concerning IDE- SCSI)

Having IDE drives detected as SCSI isn't any cause for alarm.

Many, many, driver sets for ALi Aladdin V chipsets did the exact same thing. :p
