How to interpret device manager drive Location Information

Q: How to interpret device manager drive Location Information

If you look at drive properties in the device manager, there is a 'Details' tab with a property called "Location information". It specifies Bus Number, Target ID, and LUN for the hard drive.

I have several drives and I was curious about the physical properties so I made a little diagram starting from the Device manager and cutting and pasting various other infos.

I was curious to see that I had two 'Bus Number 0' in my system - One for the JMicron drive port and one for the Marvell drive port.

Is this normal?

The picture below shows drive name, volumes on it and format type, Bus name, Disk number, and physical device object name:

I performed a clean install of Windows 10 Pro 64-bit using the flash drive shipped to me by HP. The prodocut ID of this flash drive is N3B20AV#ABA. The operating system installed without issue. However, the DVD drive is missing from file explorer. The BIOS recognizes the DVD drive and is able to boot to discs from the BIOS. I have checked device manager and the drive does not appear under the category "DVD/CD-ROM drives". In fact, this category does not even appear. Rather, it is listed under "Other devices" as hp DVDRAM GUB0N with a question mark. When going to the properties of this device, selecting the driver tab, and the driver details button, a message appears stating "no driver files are required or have been loaded for this device". Any suggestions on where I can find the driver so the DVD drive can be used within Windows? Images below show what is seen in device manager.

I am trying to figure out where is the bottleneck in my system, namely disk I/O or CPU, for my video editng tasks.

I newly loaded Win 10 Pro on a SSD drive, but found no difference in the final encoding performance, whether I put all the Video files on the SSD or a SATA 3 HD.

So I ran the Task Manager, but was just as clueless, as the data does not make sense.

I look the CPU Performance, it was never fully utilised. I presume the BLUE graph is the speed of the CPU, it varies when I change the Power setting to Balanced, and fixed at 3.2Ghz when High Performance was set. But the GREEN graphs utilitisation ( I think ) was never more than 40%, I thought OK may be it is disk bound

But looking at the disk performance whether the files are on SATA 3 HD or SSD, they were never utilized to more than 10% or so.

So it seems that the system is not disk I/O or CPU bound, what can it be?

The system was newly booted, and no other Apps are running. In fact, the Task Manager is not showing anything else that is remotely significant in the background.

Can someone help to explain this, or am I missing some other parameters?

I have a Lenovo Laptop with Windows 8.1.

Its internal DVD Writer drive is now missing from Computer / Windows Explorer, and its item is also now missing in Device Manager. The optical drive is powered and it will spin discs, is no longer
recognsed by Windows.

I believe I may have instigated this issue by confusing the functioning and effect of the Notification Area's "Safely Remove Hardware and Eject Media utility", with the Devices and Printer utilities "Remove
Device" option. This being when I had difficulties getting the Optical Drive's tray to open. Yes, of course the one option is for USB devices and the other is for installed devices,
but I just used the wrong option instead of the "Eject" option in Devices and Printers (the "Eject" option may have been missing at the time).

While I can understand the "Remove Device" option apparently completely removes installation of an internal device, what I find strange is that this apparently also leaves the user with no options for reinstalling that same device. If I spin up
any disc in the affected optical drive, and then in Devices and Printers choose "Add Device", it finds no devices to install !
I have visited the manufacturer's website under the serial number for this laptop, but although they show drivers for various functions, they do not offer drivers for the optical drive. Perhaps it was installed
using Windows drivers.

I bought a new DVD-drive today and tried to install it, but it only sees my old CD-RW drive. They work if one is unplugged and the other is connected. If both are connected at the same time, then it only reads the CD-RW. When the other is disconnected, it gives the other the drive letter 'D'. Why won't it recognize both or how can I change the letter on my old one? The Device manager won't let me type another name in for the old CD-RW.

How can I get it to recognize both?
The brand of the DVD-drive is Pacific Digital and the CD-RW is Samsung.
I am using Win. XP on an eMachines T1440; Intel Celeron at 1.4 gHz.

I just discovered that in my laptop's Devise Manger, under DVD/CD-ROM drives there are two entries as follows: 1) FvFx CDDVDvx+tech-200 SCSI CdRom Device 2) TSSTcorp DVDWBD TS-LB23A I think TSSTcorp is my dvd drive. What's the FvFx? I wanted to uninstall it but I thought I'd better make sure it's not something important. I googled it and all I could find was tons of websites offering their drivers update service for FvFx CDDCD..... Any help would be appreciated.

A:Unknown dvd drive in Device Manager

To me it appears to be a virtual CDROM drive installed by some game/software you recently or in the distant past installed. Just brood on it.

Without knowing the source - which you only know - the only brute force method of getting rid of it is to try a system restore to an earliest point of time available which may or may not get rid of it. Depends when it - the virtual drive - was created.

Right, Ive got a nasty problem with my CD/DVD drive/s.

As you can see in the attachment, the drive labelled.

"VOBID Instant Drive CD SCSI CdRom Device" is malfunctioning. Now I believe that is related to the Pinnacle Studios Instant CD/DVD SE software.

There is no Vista patch with my version of that software, so I assume its a conflict with Vista, It also started after installing Vista.

I've tried disabling and uninstalling this device, but upon restart it returns. I tried uninstalling the Pinnacle Instant CD/DVD software, but I got a blue screen half way through uninstall. So then I just deleted it manually from my hard-drive, and used CCleaner to clean up the registry. Still, that damn drive will not go away.

I wouldn't mind but whenever I put a DVD/CD into my drive and navigate to My Computer, it crashes. I created a virtual drive using Alcohol120%, mounted a file on it, and when I naviagated to My Computer it also crashed.

The only time I can actually go to "My Computer" is when ive disabled that device, but as soon as I restart, it comes back. Its really starting to pi$$ me off.

How the hell can I get rid of it?!

Thanks for reading that rather long story.

A:Device Manager/CD Drive Problem

Problem started when my PC was locking in hybernate mode. Did some research and fixed that by reseating the RAM cards, also removed and refitted battery. I have now lost my D drive? It was replaced with a 3/12 floppy drive but now that has even gone.

I have updated BIOS, checked connections to DVD drive and M'board, done the regedit thing, however i had no high level only low?
It also does not list the drive in the device manager (or my computer). The D drive was working fine before hand. I have tried to reinstall the driver by downloading it off the net but when i go to install i get a message "ATAPI device can not be found" this is then getting a bit out of my league

The Disc drive spins up when you put a disc in but seems the PC is just not recognising the drive is even there? (LG - GSA - H55N).
I will tripple check the connections again now but if anyone can help me out it would be greatly appreciated. THANKS.

Hello. I recently purchased a new HP laptop with Vista installed. I uninstalled Vista and used my existing copy of XP Professional. After installing drivers from HP's website, all was well, and the computer was in full working order.

A few weeks ago, I noticed that my DVD burner was not listed in My Computer. After further investigation, I discovered that it was completely gone, missing from the Device Manager as well, with no exclamation marks or errors to indicate a device error or driver issue. The device is not discovered with "Add new hardware." Simply put, the drive has disappeared from XP.

I am positive this is a problem with XP, as I can boot from the drive fine, and the installation of XP on another partition shows the drive working fine. Furthermore, I can repair the bad XP installation with no problems, but upon booting back into Windows after the repair, the drive is missing.

I frequently use Virtual CD-ROM drives to mount images that I have ripped. I believe this may or may not have contributed to the problem. Any suggestions are appreciated, as I have spent countless hours surfing the net trying to find a working solution to my problem. I will go ahead and point out that I have attempted to remove the LowerFilters and UpperFilters values from the registry section, per the SP2 upgrade bug. This has not fixed the problem.

Thanks in advance for any help and/or suggestions.

A:DVD-R Drive Missing From Device Manager

I'm not sure if this issue has been covered in here yet, sorry if it has, I tried searching for it but the search wasn't working so here goes...

I installed windows 7 32 bit and it is not recognizing my dvd drive. It is not showing up in the device manager or anything, but does show up in the bios. I have tried going into the registry and deleting the upper and lower filters, disabling driver signature enforcement upon startup, and entering "bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS" in command prompt, but nothing worked.

I ended up trying to boot from cdrom on startup and was able to to do that. I opened the drive, took out the windows 7 disc, restarted the computer, and windows finally detected my dvd drive and everything was fine. I eventually restarted the computer and now it is not detecting the drive again. Has anyone else run in to this or know what I can do to fix it? Thanks.

Hi, Recently I did reset my HP dm4 notebook to factory defaults setting and noticed that CD/DVD drive is not appearing in windows explorer "my computer". When I checked in Device Manager, there also I do not find it. When I push the eject button the drive opens though.  I ran the find and fix problems utility in control panel and the following message appeared "Problems found: Hardware changes might not have detected -- detected  !" I'd checked the registry if there are any upper/lower filter keys...there aren't any. I ran the command "sfc /scannow" in command prompt (admin) and checked again in device manager, but no luck. Does this mean my CD/DVD drive is gone OR can be fixed? if it can be fixed, how?

I have an HP dv6500 laptop running vista 32 bit. When i purchased it (used) the device manager did not recognize the DVD drive. It blinked when a disk was inserted but the disk did not play. When I installed service pack 1, the drive was recognized and was fully functional. Then I installed service pack 2, and the drive disappeared again. It seems like it might be a driver problem, but I do not know how to search for the driver, as I don't know which drive this model has.

My DVD Drive (Which i used to burn DVDs or CDs or watch them) won't show up in device manager even though it is attached inside my computer.

But sometimes when i restart my computer it either shows up or disappears.

When it shows up it works fine for a while but then disappears.
But when it doesn't show up, it won't show up at all.

I think the DVD name is Matshita DVD RAM but i can't remember what model name was it.

I looked for help elsewhere (Which is online chat) and they said maybe you have to replace it.

So please help!!!

Had a mate with the above issue, so I tried it out and sure enough nothing under his Device Manager so of course unable to read the discs!

No problems! Bring them all down to my place I said and we'll play with them there!

Cranked the old PC up, slipped in the DVD, green light working but ........nothing!

Didn't even show the device under Explorer .....................

Checked Device Manager and identical problem, nothing for CD/DVD Drive!

I then tried a DVD I know works and ditto, nothing!

Not be beaten, I inserted the disc on my wife's laptop and voila! Perfect, read the disc and all the contents there perfectly!

I did the usual "Scan for new Hardware" but a waste of time!

Had a look on Google and lo and behold up comes a zillion hits on this same issue.

Tried a couple of them with no luck but figure the guys on TSG are more savvy so anybody have any advice on how I correct this annoying issue thanks!

Gotta be something simple as it was working about 6 months ago perfectly, quite intriguing why the discs in question work on the wife's PC and not two others?

Hi everyone, I see this has been posted before but I have tried the options listed and it still isn't working. I didn't pay much attention to when it disapeared but it is gone now. I have tried disconnecting and reconnecting, I checked the bios and nothing has changed there, I checked the registry for the upper and lower filters and they are not there. I also downloaded the firmware and Windows won't let me install it because there is no matching drive, I even pulled another rom drive from a working system so I know it is good and still have the same problem. I went back 2 weeks and removed all the updates, I don't have system restore set back long enough to get it back. Is there any other ideas?

OK, the system is a Toshiba laptop running Windows Vista Home. It has a 200gb hard drive, and all of the system specs are as set up from Toshiba. It's about 2 years old. Previously I had partitioned off a 2nd drive from the main hard drive to function as a storage device, so the one 200gb hdd is separated into a 150gb main partition and a 50gb storage partition.

The PC is my Fiancee's, and she recently complained about her computer not working right, and said she thought she had a virus. Every scan I ran came back negative, but the PC was definitely exhibiting strange behavior...several unassociated programs randomly not working properly anymore, the laptop running half as fast as it used to, taking forever to boot, losing file associations...all sorts of weird stuff. So I backed up the data, and went to clear out the storage drive, join it to the primary, and just upgrade to Windows 7.

Here's when it gets weird...in My Computer, I still have full usable access to the C drive and the 2nd storage partition. Everything shows up and reacts just the way it should. The drives are recognized in the BIOS as well, obviously, since the system boots and all that. But when I go to Device Manager, I don't see a listing for Hard Drives at all. There are no unrecognized or unknown devices, and no devices with any errors, and a Add New Hardware search results in no changes. Worse yet, when I go to properties on a right-click of either HDD partition, and go to 'Dev... Read more

I have a Garmin GPSmap76CSx. It communicates fine through the Mapsource software, but I'm puzzled about whether I am disconnecting it properly. It shows up in Hardware Device Manager as Garmin device, not in the USB ports. It does not show up as a USB in Safely Remove Hardware as other USB devices normally would. If I try to assign it a drive letter in computer management, I'm not sure what path will accomplish that. I get to sub-folders of the Garmin, but nothing shows up to create a path for, say drive "G", which is available for mass storage devices. I have A thru F occupied, L is my external hard drive and my travel sticks always come up as M. I know some devices want one of the first 5 or 6 drive letters and won't comply when they are unavailable, but I really don't understand this well enough to proceed. First, is disconnecting the unit without doing safely remove hardware going to be harmful? If not, I guess I'll leave it alone. If there is potential for damage, I'd like to assign a drive to the Garmin - how do I do that?


A:Garmin in Device Manager, not as a drive

Hi Orkie !

Afaik you can't assign a volume letter to your mobile phone if the file system it uses isn't recognised by XP. I wouldn't try to assign it a volume letter, you could mess your phone completely if some program writes some data at the wrong place.

About the safe removal, if there's nothing in the phone's manual you may try to contact Garmin and ask them about that. But as long as nothing is writing on the GSM when you disconnect it there shouldn't be any problem. It should be ok to remove it once the bundled software is closed.

Under the voice IDE ATA-ATAPI controllers in Device Manager everything seems ok, so, can I ruled out a connection problem and go ahead and buy a new drive?
I wouldn't want to get a new one to find out the problem is somewhere else.

Hi there, I have a problem where the CD drive does not appear in "My Computer" however it does appear in the device manager. I cannot check whether it appears in the BIOS because HP limits what you can do to the laptop. This is a HP Pavilion DV6500 Notebook.

It used to function okay then for no apparent reason it has disappeared. It does not appear in Drive Management so it hasn't got anything to do with not being assigned a drive letter.

Interesting thing is. The CD tray has power it opens okay. And the drive light on the CD tray lights up when I place a CD in the drive and close it. You can even hear the CD drive powering up and spinning. But the computer shows nothing of its existence apart from device manager.

I have tried restoring the computer completely back to factory settings and there has been no change. Any suggestions?

Many Thanks

A:CD/DVD Drive not detected in "My Computer" or Device Manager

The only times I ever have had issues with plug n play not finding devices, it has been because my cable connections weren't made properly.
You should probably turn off the computer, open the case and make sure the CD drives data cable is completely on the motherboard connector. Check it is likewise fully inserted into the back of the drive.
I know that for the 4-pin Molex connectors (used for non-SATA drives), an accidental forceful tug on them can cause one of the wires to "pop" off of where it is normally secured inside the connector. This may not be obvious by looking at it. 
I would suggest using a different connector to power the drive, if there is another one available.
After checking the connections, start the computer and see if Windows finds it.

Hi Shandy59

Something doesn't sound right with your problem description

If you look in Device Manager under disks, you should see a list of the physical disk drives on your computer. Your "C drive" is a logical "disk volume". Difference being the you can create multiple logical volumes on one physical disk. (so you might have both a C and E drive on the same physical disk)

But aside from all that... what problem/error do you see when you try to do the upgrade??

A:Hard drive has 5 parts to it in device manager

Unless I am wrong that is only showing that your mobo has 4 sata I guess sataII ports. If using only 1 drive that is chann 0.

You notice the numbers skip a few. That should mean other chips and or drivers run other ports on your mobo say for ide or sata 1.5 or sataIII ports? I would guess looking at it channels 2 and 3 are ran by another chip or controller and are a different speed or interface?

Normally different interfaces use different color sata connection ports on the mobo. They can be black blue gray and white maybe other colors but is so you can tell them apart and should be listed as so in your mobo manual.

The other ports may or not show until drivers are installed or a drive is plugged into the said other ports. Windows and or the mobo bios will default to the main sata ports which in number count should be more than other ports. If a sataII mobo you might have 4 or 6 or 8 normal drive ports and maybe 2 to 4 what ever other ports for say sataIII etc.

If you have the yellow triangle that means you need to install drivers- or w7 might install them for ya..

How do i get this drive to show back up in Windows. I have tried everything "Update driver" "Disable - Enable" "Uninstall - Reinstall" Is their anything i can do? I am running XP SP2 w/ ATA 133 IDE Promise card, ASUS P4PE board 2.66GHz P4... !.5GB DDR 1.

A:Cd/dvd rom drive missing in device manager and my computer

Your System Specs gives very little information. How old is the computer, is it still in warranty?

By default Windows Explorer is set to not display empty drives so it wouldn't show up until a disc has been inserted, it's in Tools, Folder Options, View tab.

As a diagnostic in such situations I usually start by shutting the computer down, pull the power cord out of it then put the cord back and try again.

My daughter plugged our USB HDD into a TV when we were on holidays and formatted it! I never saw her doing it, she told me. Now when I plug the drive into my PC it isn't found, I can't even see it in Device Manager.
Is this drive now ruined for good?
Any ideas how to format it so I can use it again?

OS Win XP Pro, HP Pavilion, PIII 550MHz, 192 MB RAM, 41% free on 27.9GB HD

Have a system that has had its C: drive changed from FAT32 to NTFS and then defraged. The CD-RW drive is now not recognized. The Device Manager properties for it says 'Windows cannot start this hardware device because its configuration Information (in the registry) is incomplete or damaged (Code 19)'. I located the corrupt entry in the registry but cannot do anything with it. Can't even uninstall and reinstall or update driver. Regedit cannot even do anything to the entry - it fails trying. Restore points don't work because of the file structure change. I would be happy to supply any info you may need if necessary! I'm obviously not a registry expert and would truly appreciate any input, direction, etc. Thank You.

A:Solved: Win XP Pro Device Manager problem CD-RW drive

Found the resolution!! If you have taken your time to look at this problem, I thank you sincerely! The following is quoted from the MS Knowledgebase. . .
1. Start Registry Editor (Regedt32.exe).
2. Locate the UpperFilters value under the following key in the registry:
3. On the Edit menu, click Delete, and then click OK.
4. Locate the LowerFilters value under the same key in the registry:
5. On the Edit menu, click Delete, and then click OK.
6. Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.
7. Restart your computer.

Greetings all!

The DVD RW drive on my HP Pavilion dv9700 series (9920us) is not working. Please find the relevant details below:

1. The drive is Model TS-L632N/HPMH - I think this is Toshiba?
2. It's detected in My Computer as HD-DVD ROM.
3. When I try to play a CD/DVD, the light comes on and spins but then shows "Please insert a disk into HD DVD-ROM Drive (F.
4. The Device Manager detects it as a CD ROM and obviously the Windows generic driver doesn't work. The Device Manager picks it up as an "Unknown Device" and is shown as "NCB XYB09 QNKX SCSI CdRom Drive".

The driver is not available on the HP site, so tried the regedit option. I believe I deleted all the strings associated with the driver key!! Then tried the Microsoft tool, which must have installed the generic driver which causes the DVD drive to be recognised as a CD ROM instead. I tried the sfc /scannow as well and it shows that there are corrupt files, which could not be fixed. The laptop works well otherwise.

Please help! Where can I find the driver for the drive? How can I go about fixing this issue?

I have the following issues:1) When I tried to Copy Drive using Casper 5.0 (I have identical drives, C is the main drive, D is a mirror of C in case C fails which has happened before) C drive could not be found. When looking under Administrative Tools, Computer ManagementIt is missing if looking in/under:Device ManagerDisk ManagementIt can be seen underDisk DefragmenterI can find it in Explorer/My ComputerWhen right clicking on Drive C, then Properties and then looking under the Hardware tab, then clicking Properties, then Volume (and populate) only Drive D comes up. Same if I do this starting with Drive D. At the same time I noticed that I now also have the Google Redirect 'virus' - redirects seach results to other arbitory sites. Are these two issues somehow linked?Other things I have noticed: Both drive C and D don't have a name anymore. I usually call them Martin HDD. I often look at Windows Task Manager to check what's running, why the computer is slowing down, under Processes I have noticed svchost.exe Mem Usage is very high recently - between 100 to 250,000 K and is often the highest (even with no search engine running I use IE8). I've cannot recall seeing this on a regular basis before. After updating Norton Internet Security from 2009 to the 2010 version that I am continuously warned about unauthorised attacks from various sites, many with .asia extensions. Today I did a Norton Quick scan and it found a virus called svchost.exe and deemed it to be... Read more

I was just farting around earlier doing a bit of maintenance and the usual checks when I expanded Disk drives in Device Manager. My SSD, Caviar Black, Caviar Green and Hitachi USB external drive all showed up fine, but I also have a weird 'ghost' drive showing up in there too which has a very strange name.

I have no other storage device attached via USB at all for definite, and the only thing I can think of is whether this is a leftover from when I tried to apply ASUS USB 3.0 Boost to a Kingston Data Traveler while trying to get USB 3.0 speeds out of my front ports (which didn't work). That may or may not be the case, and I've no idea how long that weird drive has been showing up as I haven't checked the Disk drives expanded for a while, I was just wondering if anybody had any idea as to what could have caused that to be showing up?

A:Strange USB Drive Showing in Device Manager

I decided to uninstall the drive as it couldn't be real, so I made a Restore Point and uninstalled it through Device Manager. I rebooted and Windows installed the weird drive again.

Now I'm really confused. I can account for every USB peripheral that's plugged into the rig and they're all accounted for in Device Manager too. Opening Computer doesn't show an extra drive either. This is going to bug me until I get to the bottom of it.

Here's the situation:
Hard Drive: Western Digital
Is this a mounting problem?? If so.. how do I mount the drive?
Original problem is that the pc wont start on boot. I pulled out the drive and put it into an external enclosure and connected it to my other pc vis USB.
The drive powered up; began spinning; no strange noises etc.
The pc recognizes the connection of a USB device but it does not show on the computer other than the device manager. According to the device manager, the device is working properly and make and model is correct.
Yes, this is where you tell me to reformat but I need the data! Part of my thesis that didnt make it to the backup drive!!!!! I would appreciate any suggestions you have!

Hi, I'd just like to start off by saying that this forum is bustling with easy-to-acess information and functions well as a community. Simply put, this website has helped me with the constant stress that Vista brings me on a seemingly daily basis. Thank you.

After going through many threads on this subject (a fairly common problem?), I haven't been able to relocate my DVD/CD drive, yet. It does not appear under "My Computer" or my Device Manager. I have deleted the lower filters already to no avail. I downloaded the helpful CDGone.reg file that I found in Rollin' Rogs's post in thread


This initially helped, and I was able to use my CD/DVD drive again. However, whenever I rebooted my computer, I would be missing the drive upon start up. So, I tried to choose "save as" instead of running the program, saving the CDGone.reg file to my desktop and merging it from there. AFter doing this, I have not for the life of me been able to find the drive. I'm not very computer savvy, so I don't want to tamper with the registry without advice from the forum's well-learned posters. Do you guys have any other suggestions on how to enable my CD/DVD drive once more?

P.S. Is it possible for anyone to explain the CDGone file as it appears in notepad? I would like to try and find the registry path and perhaps try and delete it and reinstall? Perhaps that may work?
