Auto-detecting USB Mass Storage Devices

Q: Auto-detecting USB Mass Storage Devices

My Verbatim 1TB USB External Hard Drive was hanging my PC at boot message "Auto Detecting USB Mass Storage Devices... Device #01. An old thread found on this forum had a similar problem with a WD 1TB My Book. The solution found then was changing the BIOS setting to DISABLE Legacy USB support. When I checked my settings I found my Legacy USB support was set to AUTO. Following the prior threads success I changed the setting to DISABLE and the problem was solved. Apparently when faced with the choice of Enable Disable or Auto, the Auto setting doesn't always choose the appropriate action. Thanks guys and gals for a great forum site.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I recently purchased a new digital camera. I brought it home, connected it to my computer by USB, and followed the instructions to upload the pictures to my PC. I had some difficulty realizing that my computer actually recognized it as a mass storage device, but eventually it worked. I was very happy.

Less than a week later I had some more pictures I wanted to upload. I connected the camera to the computer and nothing happened. The camera did not respond (it essentually turns off while connected to my computer), the E:\ drive did not show on My Computer, and when I opened up the software I use to upload the pictures, no mass storage device was detected as being attached to my PC.

I didn't install any drivers for the camera, so there really isn't anything to re-install. It's like the computer is completely unable to realize anything is connected to it. I've tried uninstalling/reinstalling my USB root hubs, editing registry keys (http://support.microsoft.com/default...;en-us;314634), uninstalling the uploading software (hey, it was worth a shot), restarting my computer a million times, plugging the camera into different ports (I read that plugging something in to the ports on the back of my PC that are connected to the motherboard directly would do the trick--this just caused a power surge and froze my PC), and performed an exorcism.

My Device Manager doesn't show anything at all as being connected to my computer. The E:\ drive doesn't show up. Nothing.

A:XP not detecting mass storage device

The fact that your PC froze sounds like a bad cable. The only other logical solution is a bad camera port. Take it to a Drug store self service photo booth & see if it works there. Many give the option of inserting the memory card or the USB cable.

There is probably nothing wrong with your PC.

I'm having issues with my computer recognizing any sort of mass storage device. Most of the time when a problem comes up I have no problem figuring it out unless it's a laptop hardware issue - that's a nightmare.

Anyway I've tried to plug in a USB Jump Drive (128 MB) and an External USB Hard Drive (80 GB) and both devices are recognized but Win XP Pro can't find drivers for them and they should already have drivers in Windows according to the manufacturer. Heck I use the jump drive at work on a number of different systems and it works just fine. I suspect maybe a bios setting is off or perhaps another USB device is causing interference for mass storage devices. I had one case where I tried to play a game and my keyboard was causing it to crash.

- There isn't any upper nor lower filter
- Tried this post Unable to install any USB devices

Vista runs the "new hardware found" wizard when I connect my External WD hard drive and my Sony DSLR Digital Camera. It is looking of a driver. Both of the "mass storage units" work fine on my XP boxes. WD or Sony both say no driver is needed except the one windows should already have. All my usb hubs have been checked out and have the latest updates and my Vista is completely updated. The "Details " say it's looking for a PNP driver. My Sandisk memory stick however works okay with the Vista system.

Any ideas how to fix this? This is a new computer and runs Vista Home Premium 32.

HI, I'm having a problem with my mass storage devices. I updated my bios on my Asus z87 pro motherboard and since I did any of my usb sticks or WD My Passport wont open... PC says it tries to download drivers but can't. It sees the unlock disc for WD My Passport but wont let me open it and has the yellow exclamation mark by it in the device manager. As for the usb sticks.. they don't even show up even though they do in the bios page and they make a sound when you slot one in to a usb port.. so I don't think its the ports. especially as other items like flight yoke, pedals and mouse etc all work in the various usb ports.. its just the mass storage devices. I have looked at the files you suggested might not be there (as above) and all are. so bit lost as to what to do.

Any ideas?

A:Having a problem with my mass storage devices

Hello, Stevey!

I think the issue you are facing is due to faulty installation of drivers.
The yellow exclamation mark in the device manager indicates that there's some kind of system or driver issue.
You mentioned you updated the bios on your motherboard, but did you update the drivers for it as well?

I suggest to take a look at these links:

In case you forgot the motherboard drivers update:
You can try running the fixit from the following Microsoft article:
Another thing you can try is running the Hardware and Devices troubleshooter and check if it works:
Or refer to this WD article that explains how to change the drive letter of the external drive and see if it helps: http://wdc.custhelp.com/app/answers/detail/a_id/137

If you need further assistance, let me know.
Hope this helps.

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:My USB mass storage devices are not being accepted

Interesting... I have a similar problem. Could you post more information about your system, EG ram, HD sizes, speed and model? It wouldn't hurt if we knew more about the external drives you're trying to use, too.

I am using Windows XP home.

When I plug mass storage devices into my USB ports, the icon to 'safely remove device' shows up but I cannot see the device in My Computer. I have tried this with a flash drive, ipod, and a Sandisk transfer device. They are shown in device manager and it says they are working properly. They are not shown in computer management though.

My USB ports work OK with my mouse and printer, just not with mass storage devices.

Thanks for the help.

Have you tried 'refreshing' the My Computer screen? Also, sometimes restarting the computer with it still plugged in can help (can also lead the computer to say the OS is missing... If the latter, just pull it out and restart.) or you could go to Start - Run - type 'diskmgmt.msc' and then find the disk on either of the lists and right-click and choose Explore.

Hello all

Well this is a strange one.

Anytime I try to plug in a "new" (e.g. never plugged in to this computer before) USB Mass Storage device, device installation fails. When I click on the balloon that says device installation failed, it says "No driver found". If I manually choose a location to search drivers and choose \Windows\System32\Drivers, Device Manager chooses "USB Mass Storage Device" but says "could not install because there was an error". (Gee, thanks, so helpful )

I am getting this error with an old iPod Nano (1st gen!) but it will also happen with USB Memory Keys etc.

When I plug in any USB mass storage device (i.e. thumb drives, my JVC digital camcorder), my computer recognizes that they are there, but I cannot open them. To be more specific:

A:Mass Storage Devices Not Reading

I'm pretty sure it's a driver-related issue, but I can't tell you exactly which one since I don't know. All I can tell you is that after doing various driver updates on two different PCs (one notebook with Windows Vista 32-bit and one desktop running Windows 7 64-bit) I had the EXACT same issue happen.

When I rolled the drivers back everything worked again.

I'm reasonably certain your issue is due to a driver conflict.

Alright guys/gals, I'm stuck!

Here we go.... I have a Android Phone(evo4g) and I also have a 60n1 Card Reader neither of then will read cards!

Card Reader= I put any card into it slot (sd,mirosd,sdhc,microsdhc) and it WILL show in computer as a "removable device" but if I go to open them I get "Please insert disk into Removable Disk (f" or whatever drive letter for the others.

Android Phone= Same as above but going through a usb cord.

(See pics...1&2... 1 card not inserted and 2 card inserted)

Also I noticed that in my Device Manager the drop down that should be "Universal Serial Bus Controllers" is shown as "Unknown". (See pic 3)
I have uninstalled and re-installed all of the above devices and their driver (including the Mass Storage Device drivers)
I have also run "sfc /scannow" 3+ times .. all with no errors.

Now I do know that the issue is with this Computer only, because I have tested all above Devices on my laptop that is running the same OS as this one and they all work as they should!

So If you can help me out please throw your smarts my way!!!

Recently, my Pentium 4, Windows XP SP2 developed a very strange problem and I am hoping someone can help me. I was transferring some AAC files(legal) by my PNY attache 512 MB thumbdrive to my desktop. On plugging the thumbdrive into my desktop, it would no longer recognize the thumbdrive. It asked me to format the drive. So I permitted it to format the drive but it said it couldn't complete the format.

Here is what I tried so far in order and I still get the same message.

Right clicked on the thumbdrive and clicked on properties - device working fine but listed the file system as raw, tried to update the drivers but no new ones available. Tried roll back of drivers and did not roll back.
Rebooted the desktop - same message.
Plugged the same thumbdrive into my labtop - works just fine on the labtop (windows XP SP2) and on the desktop I have at work (Pentium 3 windows XP SP1).
Tried different USB ports on my desktop computer. I do have a D-Link USB 1.1 hub attached. I plugged the thumbdrive directly into the USB ports in the back of the computer - same message.
Formatted the USB drive on the labtop and then plugged into my desktop.
Purchased a new USB thumbdrive Sandisk - same message.

Ok, so first post here and it figures it's always the little things that get me stuck. I'm deployed in the Army and am the go-to guy for tech problems in my unit, which seem to be doubling by the week. So far, i've squashed most of them, but recently, the almost-hobby of portable-drive-transferring collections of movies and whatnot has been infiltrated with an odd problem that's gone past that to simple sd cards and flash drives.

Instance 1. When normal operating flash drive is plugged in to be copied onto from the owner's pc, no shortcuts were copied, but actual folders and files saved on the desktop. When plugged into the recipient's pc, all the folder names are correct, however, they've all been magically turned into shortcuts. When I looked at the target, it shows a drive letter and strange screensaver file name, of all things (ie: F:\siodo.scr). Of course, the folders go nowhere and are all reduced to a kb.

Instance 2. My roommate used his portable hard drive with no apparent problem earlier today. His new camera uses MicroSD and he used an adapter to insert into his onboard card reader to download pictures. Same exact problem happened as in the first instance. He told me about it and before I thought to stop him, he plugged his hard drive back in. Again, same thing. However, the 500GB drive shows 298 used, which is about right for all the movies and misc pics that are on there. When the drive is opened and all folders selected, size a... Read more

Hello, I have a problem with Windows 7 Build 7100. I am running a Fujitsu Amilo Li 1818 laptop. The installation went fine, I had to download a driver for the WLAN card, but everything else works perfectly. However, when I connect a USB thumb drive, or an external USB HD, I can't access it. Windows 7 recognises the device, installs a driver, and the device is visible in Control Panel > Hardware and Sound > Devices and Printers. It doesn't show up in Computer > Devices with Removable Storage. In Device Manager, the USB HD shows up under Disk drives and it says "The device is working properly" and the driver is up to date. However, when the USB HD is connected, it also creates an "Unknown device" entry under other devices in the Device Manager. This part says "The drivers for this device are not installed (Code 28), and clicking on Update Driver doesn't work ("Windows was unable to install your Unknown Device"). I have installed the Vista chipset drivers from the Fujitsu website. Any ideas how I can fix this? Why does Device Manager recognise the USB HD but also create an "Unknown Device" entry?

I suppose I should get two important things out of the way first:

1. The USB mass storage devices in question (3 flash drives, 2 external HDs) work perfectly fine on other computers. I don't believe there is anything wrong with them.

2. The USB ports seem to work just fine with non mass storage devices like CD/DVD-RW drives and an optical mouse.

Acer Aspire One netbook, Windows XP SP3. The problem seems to have arisen after I did a system restore due to some Malware (the one that plays advertisement audio in the background). After the system restore, I plugged in a USB flash drive. It appeared in My Computer, but not with its usual name. Instead, it was just called "Removable Disk (D." When I clicked it, it said "The disk in drive D is not formatted. Do you want to format it now?" It seems to think the flash drive is in RAW file format (it isn't). I tried formatting a flash drive and it neared completion but said "Windows was unable to complete the format." When I plug in an external HD, it isn't even recognized in My Computer any more.

I was fed up, so I decided to just reinstall windows using the "restore to factory defaults" recovery partition that came on my netbook's HD. It appeared to be a clean reinstall (aside from the Acer free-trial BS), but I'm still getting the same errors. I've used up my arsenal... Any ideas?

I recently had a new 80 GB HDD fitted to my Dell Inspiron laptop, and Windows XP reinstalled. Everything is working fine except when I plug ANY USB storage device into my USB port. Device manager says there is "no driver loaded for the device", but EVERY DARN TIME I try and install the driver, either from discs that came with the devices or from the Windows reinstall disc, I get a Data Error (cyclic redundancy check) message and the hardware cannot be installed.

I have uninstalled and reinstalled the drivers for all my USB ports. I have made sure my computer is USB 2.0 ready. I have run Dell diagnostics, and looked at the properties for all of the USB ports listed and there are no problems reported. I have tried installing a brand new 1GB flash drive, my Kodak Easyshare digital camera, and a 1GB MP3 player - all give exactly the same result. I looked in windows/system32/drivers and noticed that usbstor.sys (a driver I understand is linked to mass storage devices) was missing, so I searched my windows install disc, and copied it into place, and still same message.

2. Enabled the drivers going to USB in Device Manager.

Can it be related to BIOS settings? If yes, then please help me here with the entire procedure. I will be soo grateful !!

I have a Samsung laptop and a few weeks ago some of my MP3 players stopped working with it while some continued working. Infact one stopped working and another one (the exact same type of MP3 player) continued working despite the fact that all of them worked on a different computer. I found that I needed to "recover corrupted Vista driver database" and located the problem to Microsoft KB934637. I then requested the Microsoft Hotfix for the x86 version (it's 32 bit). After a day or so microsoft sent me an e-mail with a link to the hotfix and temporary password. I installed the hotfix and (other than a couple of times when it wouldn't recognise a flash drive) my laptop has been fine since. I dread the day the driver database goes corrupted again.

Now my main machine, an Acer running Vista has what looks like the same problem. I have tried to use two different flash drives on the tower today but to no avail.

Hello, I am desperately searching for a solution of a great problem I have never had before, but that I am having now after a completely fresh re-installation of Windows 7 Ultimate x64.

Each time when I plug in a USB mass storage device (USB stick or external hard drive), no matter at which port, the computer crashes, mostly after I have copied a file that is a bit larger (e.g. 100 MB), or even at once, after plugging in the device.

In my opinion these crashes cannot be caused by hardware problems though there have been made upgrading works at a computer store (i5 for i3 CPU and 8 GB RAM instead of 4 GB), because I was able to make a backup on an external hard drive after this computer upgrading and the first Windows installation, though this windows installation was not okay due to some Windows updates that failed. The second fresh Windows installation that I have made was very clean. However, now I am having these terrible problems with the USB mass storage devices that do not work properly.

I am also adding a file generated by WinDbg today.

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

greetings, first post !

i have a laptop where no removable mass storage devices work properly (they cannot be read).
the cd/dvd drive no longer can read either CD's or DVD's.
USB can no longer read thumb drives. OS is WinXP SP3.

the cd's and dvd's tested just fine in another computer, and so did the USB thumb drive.
the cd/dvd player has a drive letter, and XP correctly assigns a drive letter to the thumb drive (but prompts to format it instead of reading the data on it). when a CD is put into the cd/dvd player, no files are seen through windows explorer of the drive (0 items according to status bar).
there are no policies in the registry that would indicate a disabling of read access to removable mass storage devices. mouse and keyboard are plugged in via USB and work fine. can boot to USB, so USB reading of mass storage device only dysfunctional within windows.
scanned for malware, nothing. tried MS Fixit, nothing. can't restore due to policy disabling system restore (not my idea). reinstalled chipset drivers, nothing. removed cd/dvd from device mangler along with everything USB related, followed by reinstall of chipset drivers, nothing.

any ideas or i'm SOL and need to reimage?

thanks in advance.

edit: last thing i tried was running checkdisk, but doubt that'll fix the problem. i guess i'll find out on monday, but i'm not hopeful.

hey guys, im new here (signed up solely to ask this question cuz it looks like a pretty cool site) and i need some advice

so i built my own computer out of purchased parts about a year ago but its been having freezing problems until a few months ago (bad hard drive lol!). i havent noticed this problem til recently (due to the constant efforts to diagnose the freezing/crashing) but my computer seems to eject any usb mass storage device when i try to say.... copy files into or out of whatever drive is connected, whether its a flash drive or my phone's sd card (which is connected via usb).

For example: this happened today - i tried to drag an .avi file out of a SanDisk cruzer and the windows dialog box pops up to tell me that it has begun copying. after 5 minutes, it is still 'Calculating...' the ETA and i notice that the explorer window that displays the content of the drive has been turned into that washed-out, unresponsive state. Running Windows 7, if i try to close the window, i get the choice to either close the program, wait for it to respond, or some other thing.

this happens if i plug any usb drive into any usb port (front or back) on my computer. Wow that was a lot to write. well if anyone has come across this sort of problem before or can help point me in the right direction,

Hiya, hope someone can help. XP has decided not to assign a drive letter to any flash card reader/USB drive I use in my PC (previously used drives no longer have a drive letter in Explorer)

Going into Computer Management/Disk Management the drives are detected with no drive letter, I can give them a letter and access them but the letter doesn't stick, nor is it seen in Explorer (ie remove drive and replug, no letter, no auto open options and no sign of it in Explorer)

I've tried going into regedit, mounted devices and deleting all letters (apart from A-floppy, C-Main HD, D-Optical drive obviously) to try to force XP to assign a letter.

I don't want to do a system restore (all drives worked before) as I've just managed to instal SP3 RC2 after a lot of hassle plus I suspect this has nothing to do with my new/odd USB drive problem.

All other USB peripherals work perfectly, tis just Mass Storage Devices won't display, I tried a new drive and XP went through the New hardware bit, recognised it, said it was ready but didn't assign it a letter/ open it.

Any ideas how I can force Explorer to open the drives ? (going through Admin Tools is a pain after all)

it's driving me mad
My system:
Asrock H67M Mainboard with Etron USB 2.0/3.0 chipset
Windows 7 Ultimate with all current fixes applied

The problem:
I just discovered by accident that no matter what USB Mass Storage device (USB-MSD) I plug into my PC (and also no matter if I plug it into USB 2.0 or 3.0) the loading/installation of the necessary driver fails!
If I go into 'Control Panel -> Device Manager' the plugged USB-MSD is detected correctly BUT it shows with an yellow exclamation mark stating the driver's corrupt/not loaded.
I tried ALL available drivers from Etron (from 0.06 to 0.105). I uninstalled the old ones, I re-booted etc. but no avail.
All other USB devices work absolutely fine!
It's only USB-MSD (I trieb 6 different ones).

Any help is greatly appreciated since I'm really not in the mood to re-install Win 7....

Today I fixed a Graphics Card Driver issue (with the help of a thread here on this site)

Now I just have one exclamation mark left in Device Manager on my laptop.

Full details of my set up is in my profile, but in short:

Acer Aspire 8935g
Win 7 Home Premium 64bit

The "Mass Storage Controller" has the exclamation mark and more detil is...:

The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver.

Of course, there are no other issues, no other exclamation marks at all.

So what is this Mass Storage Controller and which driver do I need to install??

A bit for info:

PCI Bus 2, device 0, function 2

I have no idea what THAT means, except it is probably to do with where the device is physically connected (?) - does that help anyone point me in the right direction?

Thanks very much in advance for any sugggestions.

A little background info:
I had a friend of mine build this PC for me a few days ago, its custom. 
This is the motherboard I bought (new): Z-97A
I did a lot of upgrades so we had to do a custom install, I chose the default location to the same drive as my original W7 OS was on.
I installed all the drivers that came with the motherboard and all windows updates.
Even if they are not recognized the devices still get power (like my phone will charge but the PC doesnt know what it is or even see it as unknown)
While gaming 2 nights ago one of my presumed dead USB ports that didnt read my Sennheiser headsets randomly began to read it & automatically installed drivers for it after I was initially unable to get it to detect before. So it just kinda came "alive" on its own you could say

I Only have 1 Playstation controller
When my Sennheisers were detected I immediately installed the drivers for them from their website but now it shows up as "Unspecified". Before my reinstall of windows I am pretty sure it listed in the devices category with a picture of the headset.

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).

Can someone please help me ?

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.)

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.

hi. you've probably seen this before but i'm new here so i'll just post it again. i have this memory stick: it's a 4GB cruezer, ready-boost compatible but i use it to transfer files from one computer to another. it worked until 2 days ago and now, all of a sudden, my systems don't recognise it anymore. i have both vista and xp and it works with neither of them. at first i thought it was the drivers but can that be the reason on both my rigs? i haven't tried much and i'm open to any suggestion. thanks in advance for your help. daniel

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.

Hi, and thanks in advance.

I have been searching hard for this USB mass storage device driver. Just staring at my device driver window with that yellow ( ! ) has given me an empty void in my life that needs to be filled.

And believe me it's even tougher to find on Google. I've run into false files claiming to be the driver. My usb slot has been treating me like crap for a heck of a long time now. It's time it to meet its maker. So Alas i have given up and decided to ask the pros for some help. Can you help me with this issue?

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.

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????

I have a Dell XPS 8000 with a 4 in 1 card reader. I also have a DVD and a Blu Ray drive installed in the computer.

But in the descriptions in Computer, I get this:

BD-RE Drive (G SD/mini-MMS/RS

I have even moved the two drives off of the SATA ports built into the motherboard to a Startech SATA III PCI card, but this behavior continues. I have even deleted the 4 drives in device manager and had windows reinstall them. I have also unassigned and reassigned drive letters to the card readers. Nothing I have done fixes the situation completely.

The only progress I have made is that after moving the drives to the PCI card ports, I can put a disc into either drive and it will read it, and the description will change and drop the card reader description. But the other drive will keep the wrong drive description.

What can I do to fix this?

A:USB Mass Storage Device

Sounds like you have some issue involving "uppers filters" and USB ports and devices. Do any USB devices work well?

You could Google that and try to find an answer or how to edit the registry to repair it. I'd tell you but I forget where to look in the registry to do this.

In any case, if you attempt, set a restore point before.

Try a Windows Update while device(s) is/are attached. See if they need a drive letter assigned in disk management.

If not, pick your favorite one and right click on it in the device manager. Properties. Details tab. Change dropdown to hardware ids. Copy and paste results here. No screenshots as alternative, please.
