A:Need help with usb mass storage not working.

Hello ,

you need to rebuild your USB tree

try this

now what i you need to do is go to your (device manager)

now once there you will want to select from the toolbar of the window(veiw) then a drop down menu / from it you will select (show all hidden devices)

now if you see any (red or yellow) quotation marks , make a note of what they

now scroll down to your (USB Device Tree) and uninstall all that it is shown / then shut your sysem down compleatly then unplug all (USB Devices) then rebot your system 2 to 3 times

this will cause Windows to rebuild the (USB Device Treee & Drivers)

now try hooking up your (USB Devices) and see if they work properly

If you have a USB mouse & keyboard then you need to switch over to PS/2 to perform these steps

let me know how it works

The Microsoft Update site detects that I have whatever uses/needs this device driver (Windows 98 SE):

Promise Technology - Storage
49 KB/ Download Time: < 1 min
Promise Technology Scsiadapter Driver Version

In my device manager next to Other Devices, I see the yellow question mark. Under Other Devices, there is a yellow question mark, with a yellow exclamation point over it, and says: PCI Mass Storage Controller.

I thought I was familiar with all the actual devices, but I don't know what this is, and the explanations I'm finding on Google don't make any sense to me at all.

I have noticed the Update site listing and the device manager's yellow symbols for many months. Thanks for any help.

Hi, I recently bought a fairly high spec refurbished computer from a school clearance sale and I am now wanting to use it to be the basis of a simple media center. The problem I am facing Is that it wont recognize my mass storage devices (memory sticks and an external HD) through the USB ports. It Knows they are there because it will show me the names but it wont install them automatically and brings up the 'Install New Hardware Wizard' I've tried using this but it will reach the end of the installation and then say Invalid data. I have checked with the drivers on my laptop and there are the same ones on the new PC.
I am aware that some schools deliberately block USB storage devices for a variety of reasons so I googled my problem. It came back telling me that to disable/Enable USB ms devices there is a simple registry tweak, to change the DWord "start" value to 4-disable or 3-enable which is located at:
However, when I checked in RegEdit there was no USBSTOR directory at all. I have many questions,
Does this directory exist as a default or is it something that is added for this tweak?
Is there another way of disabling the USB for hardware other than mouse and keyboard? If so how can it be reversed?

A:USB mass storage drives are not working

I just checked 2 of mine.
USBSEOR is there
Go to the Device Manager & see if the USB is listed & enabled.
If it is expand the listing, right click each [in turn] & uninstall them
Restart the unit to let them reinstall
when done try them.

What would cause all USB peripherals to work, with the exception of Mass Storage Devices? No Blackberry, No Ipod, no thumb drives.

It just says USB device not recognized.

A:Solved: USB mass storage devices not working

Is this on your Windows 98 computer? Windows 98, out of the box, won't use those devices like 2000/XP and newer because it does not ship with generic drivers (2000/XP do).

Check this out for a generic Mass Storage Device W98 driver. The site claims it will work with "most" USB devices.

I can't think of a solution off the top of my head, so this will be trial-and-error.

Okay, here's the deal:

I have the following USB Mass Storage Devices, and none of them are working.

~SanDisk 6-in-1 Memory Card reader
~Memorex 512m flash drive
~Nikon 5700 Digital Camera
~Samsung Yepp T7z Music Player

I also have the following USB Devices that ARE working, which are not classified as Mass Storage Devices:

~Targus Wireless Laser Mouse (Descriptive, huh?)
~Sony Clié PEG-TJ25 (Palm OS 5.2)
~External HDD (Samsung 40G mounted on an external HDD kit, not detected or classified as Mass Storage, but as a physical hard drive)

These devices are installed on Windows XP Professional SP2. All Windows updates are installed. They worked properly until I bought a new mobo and CPU. (Ran repair from boot CD after installing them, just to be safe)

I'm probably forgetting some non-Mass Storage devices, but that doesn't matter. The point is that my Mass Storage devices don't work. They all work fine on another computer running the same OS.

I can go to the Device Manager and I can see them, it says they're working properly (It always says that, whether something is actually working or not)

So, here's where it gets wierd: I can go into Disk Management and I can SEE the devices plugged in, and there's no drive letter assigned. Okay, easy enough, just assign a drive letter. (In this case it's F, as it's not in use by anything else) So I go into My Computer, it still ain't there. Also, when I reboot the c... Read more

I have in my computer an internal Mass Storage that performs the backup every day.
Mi question and doubt is the following:
Suppose that a file from the Operation System get corrupted, or a file from a program get corrupted ( for example Paint program does not work anymore ).
Did the backup stored this corrupted file rendering it impossible to fix ?
Or the backup keep the image of the Operation System out of corruption danger ?

Some while back I installed Acronis True Image Home 2012 on my Win7 64 bit PC. It is a backup solution that would have satisfied my backup requirements at the time. I immediately found a problem with the fact that it failed to recognise my network drive as a backup location. After days of communications with their support dept. and a couple of sessions of remote support they realised that the software was not happy about "empty" disk drives. I have a built in multi-port card reader and also have card readers built into the monitor. They show as disk drives in "My Computer" even when there are no cards in the slots. The option in Windows to "hide empty drives" didn't cure the problem.

They eventually sent me a patch that cured the network drive recognition problem but left me with the problem that my PC no longer recognises any USB mass storage device or any memory card plugged into either of the card readers. I didn't realise I had this new problem for some time as I don't use USB disk drives. It's not just USB attached devices that are not recognised, it also won't recognise firewire disks either. I have tried un-installing the Acronis software but it doesn't remove the errant driver(s).

I've tried removing the devices and rebooting to force an update and I've tried scanning for new drivers without success. The PC tells me I have the latest drivers installed.

I have now found the 2 errant drivers and remove... Read more

Fault: USB Mass Storage Devices, (USB Ext Harddrives and Flash Drives) can not be used after latest Windows updates, but only after you power off the PC. (Issue not seen when Shutting down or Restarting after the update. Only after powering off

Casually. In very random situations. I still find it very frustrating and I was hoping someone has any solution. Thanks and have a nice day

Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.

When this is done, reboot TWICE.

I've been trying to download pics from my digital camera for a few months now. The pc acts like the USB cord is not plugged in. When I go to intall new hardware it doesn't find the Camera plugged in and try to install it on its own like I believe it should. (I may be wrong.) So anyway, I go to add/troubleshoot USB Mass Storage and it says: This device is not present, is not working properly, or does not have all its drivers installed. (Code 24). So, what am I doing wrong? It worked fine until one day the USB cord was unplugged. (At least I THINK that's what caused all this crap.)

Do you here any sound when you plug it in? Like the USB connection sound, but slightly different?

If not, then worst case scenario is it might have died. Happened to mine a couple of months ago. They are fragile and can get zapped easily with things like an ESD.

We recently purchased a FujiFilm FinePix 1300 digital camera. This camera uses USB Mass storage to access the smartmedia. As of this writing, I have installed and un-installed the driver countless times in any type of boot that I could come up with! No matter what is running, be it my few startup programs or just SysTray and Explorer, the computer ALWAYS locks up tighter than a drum whenever we try to access the camera. So tight that I have to overide via the power button to shut down. I'm running a HP Pavilion 6630, 256MB ram, Win98se. This is really frustrating! As I was successful the first try at installing it on my HP pavilion 4430 at work. It ran like a charm!And I might mention, that program wise, this computer and mine at work are almost identical in the installed programs. I use my home machine for work also!

Anyone have any ideas before I throw in the so called proverbial towel, and return the camera for a Sony????

If I have lots of files (more than 70) on a DVD-RW. Windows takes ages to read the disk and be ready to access the files.

Is there an optimum way of doing this that makes Windows happier?

I update the files fairly regularly.

I do have DVD buring software. (In any case, if I use Windows to update the disk, it finalises the disk.)

I remember with earlier versions of Windows using a UDF reader, and then there was no speed problem.

A:Using DVD-RWs for mass storage

I am not sure I understand what yu are asking. I think you are asking about using DVDs for backups. If that is correct, I would suggest investing in an external hard drive. They are relatively cheap right now and all of the information is in one place. I have 4 externals and use them daily. Redundancy of backups is the key. esata and USB 3.0 if you have them are great and much faster.
If you decide to go that route, look into using microsoft sync toy. Once you set it up, just push the run button and it will syncronize any folder or entire hard drive you want. I use it for my user folder. Best of all, it's free.

I have windows 7 enterprise edition. Couple of days back I had plugged in external harddisk and after I am done with that, I did not find "Safely Remove...." icon on the tray. Normally if I can not stop the harddisk, (even if all the apps and windows are closed), I go to sleep mode, remove the harddisk and wake the OS up. But last time I tried something different. I disabled the USB Mass storage (I read this some where on the net and they said to enable it after removing the disk) device under device manager. But I can not see that icon/device back in the list to enable it back.
Now if I plug in my harddisk OS won't do anything. If I plug other devices like USB mode, it works fine. How can I re-enable it back ? I tried to search , but could not find a solution (there was one solution for XP, as it was registry stuff not sure whether the same works for 7). I tried penyuusb, but due to some problem it is not getting activated (free software).

I tried an official win 7 pro dvd, I tried a bootable win 7 usb and still no luck. I went to Asus' website and click on win vista64 OS and only drivers available was the ACPI, and BIOS drivers. 
My conclusion is that this mobo is so old and it wasn't meant to have win 7 installed on it. If anyone has ever ran to this issue or anything similar, some feedback or advice would be much appreciated

Edit: The only mass storage drivers I have found for the nforce 410/430 are for Vista and XP. It seems Windows 7 should have those as part of the OS.
Edit: If the drives are detected in BIOS and SATA ports enabled,  I found this. Hopefully you can strip out the basic sata drivers out.

Hi to all,

My notebook works under Windows XP Pro SP1 (French version) and I wished to extend its storage capacity with a USB hard disk.

I purchased a first one (80 Gb) with an external power supply which never worked properly and I discarded it.

Now I purchased a new light unit (40 Gb - USB powered) which does not install successfully.

The problem may be that in the hidden units of my configuration, I still find the old mass storage with its 3 generic volumes (partitions) which I can abslolutely not delete from the configuration (uninstall does not work).

Can anybody help me ? .... many thanks in advance.

Yes I am guessing, but from what you are saying, it sounds like Creative has its own proprietary disk format?

I do this on a regular basis and have no problems. I know on some machines it will memorize the USB port if something went wrong. Did you try another USB port with the flash drive?

I am wondering if ti normal for me to have the green arrow icon in the start up corner of my desktop I am talking about the icon which when I place my mouse cursor over it "safely remove hardware" . i do have an external drive connected by a USB but it is turned off and the icon remains even when I unplug the USB cable.

A:usb mass storage device?

I think as long as you have anything hooked to USB you will have that. I have 2 printers and a scanner hooked USB and the icon is always there...

In device manager Under the tab Other Devices is Mass Storage Controller, it has a yellow triangle with a black exclamation mark inside. I can't seem to be able to update the driver or do anything with it to get it to install.

I also have another device with the triangle so here are the hardware ID's for this aswell.

I keep getting a "USB Mass Storage" error. Anyone have an idea what the problem could be?


A:USB Mass storage error

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

hello all i have what i consider a hard problem but someone here can help me with. i puchased a usb 2.0 mass storage h/d. been using it for a while with no problems, i let a friend borrow it for loading some files, format and reload saved files. he told me that he installed what he wanted to keep, then formatted his hardrive with mine still plugged in. when he attempted to use it after the reloade windows would not allicate a drive letter for the drive. i think the hardrive just needs formatted and re-partitioned, but i can't figure out how too do it because there is no signature to the drive. i have tried usb boot drivers for dos and got an error usb target not found. the drive does show up in devise manager but i can't access from windows. i am running windows 2k pro on service pack 4 , the format was done with win xp pro corperate. all i want too no is how too resetup the drive. any answers would be appreciated. thanks THE NUT.

The error you describe is usually the result of an application, file, open document which is in use (running from the USB flash drive) when you try to remove it by clicking on the Safely Remove Hardware icon in the notification area. The error can also be caused if your anti-virus is actively monitoring/scanning the USB drive. Normally, when removing a fash drive from a USB port, Windows should stop all the read-write operations on the drive so that it can be safely removed.

I have several older MP3 players (like a Archos Jukebox 20) that have no
drivers for them directly supported by WMP10. They are however recognized in windows
as Mass Storage Drives with assigned letters. What has to be done to make
them automatically appear as devices in the WMP10 sync window so I can manually sync to them?
