Windows 2000 Wont see a hard drive

[brjames]

Hey, I just (re)installed Windows 2000. I haven't used windows for a while and I'm having a problem getting Windows to see a hard drive. This drive is a ~200GB hard drive on a separate add-in ide card (Promise Ultra100TX2). There is another hard drive on the other channel of this card. Both hard drives show up in Device Manager( UDA UD12 00AB-00C@A1 SCSI Disk Device and WDC WD20 4BA SCSI Disk Device), but the 200 GB hard drive does not show up under Disk management, whereas the 20 GB disk does. Which is strange since the 20GB drive has about 10 linux partitions on it, while the 200GB just has a single NTFS partition on it.

I can access both drives in Linux. I'm also not quite certain of the size of the missing hard drive, maybe its 120 GB (like I said its been a while since I've been in the Windows world). I've also already added support for drives greater than 137 GB (my main hard drive is 160 GB). If anybody knows what I'm missing please let me know. I can give more information if its needed,

Got the right drivers installed?

You must do a registry hack so it can see it at full capacity. Memory serves me not right as of now, but it was: "Enable BigLga = 1" somewhere in the HKEY_LOCAL_MACHINE.

Do a search in MS' Knowledge Base.
I found it there.

What Service Pack are you running for Windows 2000?

 

[nweaver]

go into computer managment and add a drive letter (mount point) right click my computer, manage, Disk manager (or something like that...)


mount /dev/hdb1 /usr is sooo much easier sometimes

lansalot: Yes, I downloaded the drivers for the ide card from Promise's website. As I said, it can see the other hard drive. Just not the bigger one.

Aenslead: Already done that. As I said, I can see all of my 160 GB hard drive now, just not the ~200 GB drive.

spherrod: I am running service pack 4, with all the latest updates.

nweaver: Disk Management doesn't see the hard drive. Thats the problem. Device manager sees it, but not Disk manager. And yeah, Linux can be a lot simpler some times,

Thanks for the suggestions, any other help?

might wanna try using a different ribbon cable and using a different ide port? one of them might be bad. also how are your bios settings?

 

[brjames]

hmm... but linux can see the drive just fine. I would think (ok, i know its not always true, but ususally) that if linux can see and use some piece of hardware, then Windows can as well... it just needs the proper tweaking of hardware.

 

[Aenslead]

Queer situation you hold. Have you used Managing Tools?

 

[nweaver]

remove it from device manager and scan for hardware changes? (action menu)

I have the exact same problem. I used to have WD20 running on promise for years fine but now I made some configuration changes and this problem just came up.
I also posted a question on experts-exchange. Maybe someone will be able to help.
Still - I'll tell you what I think might have caused my problem. brjames, please tell me if any of these apply to you as well:
1) You actually use at least 3 IDE channels (Both channels on the card + at least one on the motherboard or both channels on the motherboard and at least one channel on the card).
2) You use a 40-conductor cable for the WD20 drive.

Allright, the problem's been solved. The problem is the cable.
For some weird reason Windows cannot access 7200RPM drives connected throught an old 40-Conductor cable (though other OS's can).
Solution - Replace your IDE cable with a new one (they cost about 5$, shouldn't be any problem).
