Missing unknown driver

I upgraded and performed a clean installation of win7 from vista. From 32bit to 64bit.
There's a problem with one driver it says:
LOCATION: Microsoft ACPI-Compliant Embedded Controller
vALUES: acpi\vpc2004
*vpc2004

First try to run Windows update and check the optional updates.
If no driver is distributed through Windows Update, you should contact the manufacturer or vendor of the hardware to supply the correct driver.

In case none of these yield results, it might be worth investigating what chipset is used in the laptop and checking with the chipset manufacturer whether they have a driver available.
note that many manufactureers will remove support for the Windows XP models as XP itself is no longer supported by Microsoft.

RAID Missing/Damaged Unknown Drive

I have a RAID mirror that had a drive go bad. I replaced the drive, but now the mirror reports a ghost drive that is missing or damaged but with a Device Node of Unknown.
I used diskutil checkraid and get:
Name: Mirror 1
Unique ID: 89E317AC-F25B-44AA-8E3F-FB583001F6F8
Type: Mirror
Status: Degraded
Device Node: disk7
Apple RAID Version: 2
# Device Node UUID Status
3 disk4s10 129D802F-2622-4EC7-AA78-36E1E938F99E 4% (Rebuilding)
2 disk6s3 4F23DE97-9066-411C-BF01-2001CDAA00FA Online
2 Unknown Missing/Damaged
2 Unknown Missing/Damaged
This is the results after attempting to remove and add both good drives from the RAID. With the mirror degraded like this I can't properly monitor the RAID. The RAID is functional, just not monitorable.
How do I get the Unknown drives to go away and put the RAID back into a normal on-line state.
Thank you for your help and tips,

There are several different chipsets that support port multipliers. A 4 port PM capable host card will support up to 20 drives, while a 2 port supports up to 10. The 4 port cards are usually significantly faster performers. Most any card that states it supports port multiplier will run most any port multiplier enclosure.
At the enclosure end I have only ever seen Silicon Image or Marvell chipsets used. And either SIlicon Image or Marvell based host card will run either of them.
That said, it is always possible you have something I have never seen or tested. Without details on the enclosure all I can do is guess or just tell you is get a PM capable host card and hook it up. Or you can pull the port multiplier board out and read the chip info off it.

Missing chipset driver

Hi,
I installed Windoze XP on my ThinkPad T500 but I am missing a driver. I have an unknown device in Device Manager called "SM Bus Controller". According to a Lenovo web page this refers to the Intel chipset, which is GM45. However, no amount of googling seems to be able to turn up the missing driver. Any advice is appreciated.
Solved!

Hi,
I would suggest not to search Google but use the forums search function.
You´ll get plenty of entries regarding SM-bus driver.

Where's my missing hard drive space?

I posted earlier about this, it may be a bit off topic but if anyone can offer a clue, I would appreciate it.
I got my win 7 upgrade and was waiting until vista started giving me headaches or the win7 service pack1 came out to upgrade...vista got me to upgrade today and I have to admit it was much less painful than i anticipated.
My question is about the missing hard drive space on my Idea center K230 on the box and on the side of the comp it claims a 640 HD (it claims in small print that up to 18gb may be used for the service partition) I questioned this when i first got it and even after deleting all the preloaded crap it was still saying 540 available out of 580GB....then I read that Lenovo has a huge partition for backup. So when I do my upgrade to win 7- 64 bit, I do a clean install and delete the smaller partition and reformat and expand the larger but before installing the new OS it says I have 596 available, so where the hell is the other 44GB of hard drive...did Lenovo rip us off and put 600GB hard drives in the K230's or is there a hidden partition still left that I cant find?
I am running everything off of my 596GB C: drive, I have my virus stuff and video card extras loaded, everything from the upgrade and 21 available patches and new drivers for most of my stuff....right now I am at at 575gb available and if i can ever find a printer driver that works I will create a backup point or disc from there, whatever win 7 allows. I never wanted the Lenovo one button back up and thought it was stupid to put a big glowing button on the keyboard that wipes your system back to when it came out of the box...I had nightmares of someone getting curious and going "what does this button do?"
.I notice I have a program files folder and a program files (x86) folder with a bunch of redundant files. what's the deal with this is Lenovo still hiding a backup program (maybe in that hidden partition?) that fills my hard drive twice as fast or is there a purpose for the file copies?
Any info on the above questions would be appreciated, and for those of you just looking for upgrade info I have good news, when you finally get your win7 upgrade disc it is the easiest windows installation ever, almost copmpletely automated, and very fast. So far the only sticking point is finding a printer driver, but I have 3 printers i can try, maybe one is supported.

Hi wise2u!
You can read all the details about how storage manufacturers use multiples of 1000 to measure disk space, and Windows reports it in multiples of 1024, and there is some overhead for Windows, or you can just use this rule of thumb from wikipedia:
A general rule of thumb to quickly convert the manufacturer's hard disk capacity to the standard Microsoft Windows formatted capacity is 0.93*capacity of HDD from manufacturer for HDDs less than a terabyte and 0.91*capacity of HDD from manufacturer for HDDs equal to or greater than 1 terabyte.
0.93 * 640GB = 595GB, which is about what you're seeing.

I upgraded Windows 7 to Windows 8 with iTunes installed. Now my iPhone 4S is no longer recognized in iTunes. Connecting with USB sends me directly to the MS app that downloads pictures from the iPhone. Suggest this is a question of missing Apple driver.

I upgraded Windows 7 to Windows 8 with iTunes installed. Now my iPhone 4S is no longer recognized in iTunes. Connecting the iPhone with USB sends me directly to the MS app that downloads pictures from the iPhone. Suggest this is a question of missing Apple driver for Windows 8, iTunes and iPhone. MS does not care! This seems to be a general problem with Windows 8 that a number of drivers that used to work with Windows 7 now do not work, ie. iPhone to iTunes, HTC to HTCSync, Samsung to Kies etc. I need this connection to work in order to syncronize with Outlook and my iTunes library.

There will be a new version of iTunes released this month... no one forced you to upgrade prior to a supported version of iTunes being released.

Missing *.inf driver for 2605dtn and windows 7 64 bit

missing *.inf driver for 2605dtn and windows 7 64 bit
I just piurchased a new HP laptop with windows 7 64 bit installed. I do not have any windows 7 disks.
Where do I obtain the necessary drivers for this printer?

HI RandyJohnson,
You do not need to download drivers for this product. Print drivers for your product are available within the Windows 7 operating system. Use Devices and Printers, formerly known as the Add Printer Wizard, to obtain the Windows 7 update. For more information, go to Install the Printer Driver through the Windows 7 Operating System (c02536257) (in English).

GPP - Missing Mapped Drives

Domain Functional Level: Windows Server 2003
Domain Controllers: Windows Server 2012 R2
Workstations: Windows 7 PRO, x86
I'm mapping network shares for my users using GPP, running under User Logon, and Item Level Targeting. The missing network drives are Windows Server 2003 R2 SP2 file servers. The network drives that DO map are Windows Server 2012 R2 file servers.
When I log in as a test user (copied from an offending user), I can browse to the 2003 shares via UNC, and I am capable of manually mapping the drives are well. However, when I log off and log back in, the drives are missing again
for the 2003 shares. Furthermore, I'm mapping user's home folders via Profile tab in their user accounts, and that's going to the same 2003 share as well. That isn't mapping either.
I believe that it was working fine last week, but then SOMETHING must have changed. I'm unsure of what though. Perhaps someone can shed some light into this?

> When I manually a) selected all mapped drives, b) disconnected them, c)
> logged off and back on...my mapped drives did not show up. However,

Not to my knowledge - they SHOULD be present again without gpupdate. The
log I mentioned above might be helpful.

In most cases, they do :)

G500 laptop upgraded to windows 8.1 now have a message missing a driver

My G500 laptop just upgraded to Windows 8.1 and now my alert action center message tray says I am missing a driver?
I can’t find anything missing? I looked through all the devices 5 times but nothing is marked with a question mark or similar?
Any thoughts?

Hi deagonslair2013
What you describe has been happening since the preview, Because all devices on a network talk to each other the driver error may not be on your G500 but on another device on the network.
For instance: I own a G700 & G505, I connected a tablet to the G505 & it installed the device but could not find any drivers for that device, Since then my G700 has been showing a driver missing although all devices are working fine on the G700 in device manager.
If you have any other laptops or desktops on your network with device drivers missing disable those devices & re-run the hardware scan on your G500 & see if that is the cause.
Edit What version of Lenovo solution center do you have installed, It should be version 2.3.002.
If your version has a .18 in the string its out of date & you need to update to the above version.
Hope that helps!
And welcome to the forum.

My HP 1210xi will not re-install from disc or online, says unknown driver, what do I do

My HP 1210xi quit scanning and when I went to online help I was told to re-install printer., Un-installed it and now it will not go on the computer at all, just says can't finish installing because of unknown driver. So I went online, downloaded the software and driver on computer and it said the same thing. I know the printer works because I can still copy. Anyone have any suggestions, I can't afford a new printer as I am retired and on limited income.

Hey!
Glad to hear that you and your family made it through relatively unscathed! I think we all need to take better care of our wonderful planet, because I think we are upsetting Mother Nature!
I have the Windows Installer Clean-Up screen up and tried to upload a screen cap for you, but IE immediately shuts down every time I try. So I'll have to transcribe the screen for you:
I see the following:
(All Users)
(All Users) [1.2.0.10]
Those are the top two lines. The following lines after that are programs he has installed on the machine like Acrobat, Adobe, Autodesk Inventor, and such and they all have a name and program number in brackets.
And I now again have the obligatory Apple programs installed and listed again:
(All Users) Apple Application Support [1.5.1]
(All Users) Apple Mobile Device Support [3.4.0.25]
(All Users) Apple Software Update [2.1.2.120]
(All Users) Bonjour [2.0.5.0]
Please note that iTunes is NOT LISTED.
Everything else 'appears' to be normal, I'd say.
Take care, and I'll see you on the flipside! According to my clock, it's 4:11am Thursday morning there!
See ya!

Missing d drive on Lenovo 3000 N100 system

Can anyone help me to recover a missing d-drive? I can not find my original cd's that came with my system. Any advice or help will be appreciated.
Thank you.

Thanks for the answer. I just wrote a long reply but somehow I managed to remove it, I'll do a shorter verison instead.
I know this has been discussed elsewhere, I mean my first post starts with me saying just that. I was unsure however if that discussion was applicable to my system, hence my post. I know that KMS isn't enabled by default thats why I wrote about it in my initial post , trying both with and without KMS. The acpi_brightness=vendor was the first thing I tried, but I noticed no difference so I removed it again, and that was part of the reason why I posted this here, instead of in other posts.
Anyway, I found out that I can manipulate the file /proc/acpi/video/GFX0/LCD/brightness in order to manually change the brightness. So I wrote a script that steps up and down in brighness level, so everything works ok now. Actually after your post I tried adding that acpi_brightness=vendor in my menu.lst again, and that breaks my script and the Fn-up/down buttons still doesn't work. The /proc/acpi/video/GFX0/LCD/brightness file now just says "<not applicable>", or something similar.
A final weird thing is that when I manually change the brightness to somthing other than 100, the Fn-up/down buttons start to work, but in a buggy way. They just step either down to 0 or up to 100 without intermediate steps. Once the brightness is back at 100, the buttons stop working again. I tried to fix this by adding my scripts to handler.sh in /etc/acpi/, but it still works weird. It is as though something else is also listening on these buttons?
Hmm...this wasn't so short after all, but anyhow things work ok so I'll just be patient and wait to see what happens when the new kernel hits the repos.
Thanks again.

Missing Audio Driver in Windows 8.1 64 bit

I have a HP Pavilion m7750n that originally was installed with Windows Vista. It's had it's hard drive replaced many times over the years, and now it's running on Windows 8.1 64 bit.
The problem is: the audio driver went missing somehow
I can't find it on Device Manager (no "Unknown Devices" show up on the menu)
The only "Sound, video, and game comtrollers" drivers that show up are:
1. Hauppauge WinTV HVR-1600
2. NVIDIA High Definition Audio
3. NVIDIA Virtual Audio Device
All of this happened after I used the "Refresh" option Windows 8 has. The right sound driver showed up on Device Manager and worked before I did this.
On sound options it says the only audio devices I have are some HDMI outputs. The only way to get sound out of my PC anymore is to hook it up to my TV from a HDMI cable connected to the HDMI port on my video card.
Does anyone know how I can find the audio driver so i can use my desktop speakers again?

Hi,
It uses "Realtek High Definition Audio" and Microsoft says it's compatible but many people say no:
http://www.microsoft.com/en-us/windows/compatibility/CompatCenter/ProductDetailsViewer?Name=Realtek%...
Please try:

or
http://drivers.softpedia.com/get/SOUND-CARD/REALTEK/Realtek-High-Definition-Audio-Driver-6017161-for...
Other option: does it have a spare PCI/PCIe slot ? Buy a PCI or PCIe aud card and install on your machine.
