I am running Windows XP Home.I recently installed Daemon Tools.( a very useful prog).
Howver unfortunately Windows is now unable to detect all usb drives and devices that i have connect to my cpu.
I am wondering whether this may have something to do with Daemon Tools and the vitual dvd drive letters etc?
Maybe someone can help....

Many thanks in Advance..

Best GLEN

We are a gaming center and we have the same kind of problem, since version 4 no USB flash drives are detected properly, we see them in the disk manager but they have no drive letters and cannot be found elsewhere...

We also use Deepdreeze Enterprise 5.20 if that can help... The problems with USB start after we freeze our hard drives... The problem wasnt there with previous D-Tool versions...

Thanks in advance

My problem is almost the same. But, I can't connect my mini USB HDD 2.2Gb (Like a memorykey). When I plug it, the system detects something in USB, but do not assign a drive letter, so I cannot access the files.

This happen after I install DT 4 :(


I already disabled all virtual drivers and uninstalled DT 4, and problem doenst disapear.

My others USB devices is working perfectly (joystick, mouse, webcam)

Anyone can help me?




OS: Windows XP SP2
AntiVirus: NOD32
Other Softwares: Alcohol 120%, Roxio Easy Media Creator.

Does anyone use any nonstandard USB drivers?
Or all are out-of-the-box Microsoft ones?
Are there any messages in the system event log?

I still haven't discovered what the problem is yet although i have no conflicts in Device Manager , even though i cannot see the drive at all not even in Disk Manager.

I may resort to a system restore if i don't get any good advice soon..

At least i am not the only one.

Please check the properties of drive in device manager too.
No problems there? Which drivers are listed?

My external usb drives or devices are not detcted or listed.

My usb drives are ide hdrives built into a standard ubs/firewire case.

I am running xp home. 3.5GHZ 1.5GIGRAM

Its all a mystery.

My usb devices disappeared after i mounted all 4 virtual drives.
My drives were not on at the time.

I have now removed Dtools for the time being until i sort out this problem.

Thanks for any help.

it seem to be an out of the box driver, but I also tried our motherboard drivers with no success...

It listed the drivers as "USBSTOR.SYS" as stated in previous replies, the device does show in the Local Disk Management section of windows, but with no Drive letters attached to it, if we assign a letter to it and then remove the device and put back the letter disapear again and the letter become unvailable like its been use but not for our USB device... I hope I make sense...

As soon as possible I'll post the event in the log... I aint at work atm...

Hello! I had the same problem as many of you have, when i pluged in my USB memory stick it didn't show up in explorer. I simply deleted a file in c:\windows\system 32, this file was called sptd.sys. It is placed there by Daemon 4.0 and even if you remove Daemon from your computer the file will stay there since the uninstall don't want to remove it, it might be used by other programs? So after a looong weekend i got my removable disc back again in explorer!!!!

Holy crap thank you so much for posting that information.

I actually found 3 files relating to the problem;

secdrv.sys
sptd.sys
sptd7021.sys

All were created on the same date. I deleted them, rebooted, and VOILA!

Wonderfull! I've had this problem for sometime now. Both my MP3 player and digital camera stopped showing up in the explorer. But thanks to both of you they now works perfect.

But the files I found were in c:\windows\system32\drivers.
I didn't find sptd7021.sys, instead I found sptd3677.sys

I seem to remember installing DT some time ago but I never used it so i removed it. Guess these files were left behind.

Hi all,

I am in the same boat.

I run an internet cafe and we use DT4.03.

The USB drive not showing up issue is, in some forums, attributed to network drive mapping conflicts. However - I did a brand new XP Pro SP2 install this weekend in order to fix this, with no network drive mappings or anything fancy, and the same issue has arisen.

I uninstalled DT4.03.
All the stpd and secdrv files previously mentioned have been removed, and now I have the issue of NOTHING being assigned a drive letter apart from the C:\ and a DVD drive on D:\

It's like the Disk Management is locked - manual assignments do not work.

I re-installed DT4.03.

Drives detected in Device Manager - no drive letters being allowed.

Same with USB flash drive (which works fine on other XP machines both at home and in office).

So in summary.

USB flash drive detected but not assigned a drive letter.
Auto assignment refused.
Manual assignment refused.

New install of Daemon Tools (creating 1 virtual drive by default) installs ok, detected virtual drive ok.
Drive assignment refused.
Manual assignment refused - from XP Disk Management as well as from the DT 'set parameters' section.

There are no mapped network drives and there never have been.

It seems that there are many users out there on the forums of the world with a similar, if not identical problem.

Many have arrived at the conclusion that it's just a windows bug and we
have to live with it or re-install.

As for re-install, I have a custom XP disc (nlite) which oddly will not give me that facility (even though I kept the option to have it in my iso as per the installation app). So this currently is not an option for me (after spending all weekend doing a BIG install).

If I can get an answer to this, then I will be visiting many forums to spread the good news.

Any thoughts would be most welcome.

Thanks, Dan.

Yeah I have the same problem.. my DVD-R/DVD drives say the drivers aren't loaded but they are, and uninstalling d-tools and those aforementioned files left behind don't resolve it. I'm in a panic here because I need at least one drive for stuff from work!

Hi all.

I get a hard freeze (requires reset restart) whenever i plug an USB memory stick into my WinXP Pro PC.

Everything worked well until I set up virtual drives to 2 and mounted the second virtual drive. Before I had one virtual drive and it didn't matter if it was mounted or not.
I have tried so set virtual drives to 1 and 0 unmounted and mounted in several combinations. I have not tried to uninstall DT yet.

One strange thing is that my Ubuntu Linux system installed on the same PC - or other LiveCD distros for that matter - now can't find my USB sticks either. This was also working just fine until I set virtual drives to 2 in DT/Windows!?

Can it be a hardware/BIOS related problem?
I have no clue at the moment, but I will continue my struggle and post any solution here.
I'm no hardware hacker and will salute any ideas that can be of help.

My USB sticks work fine on other computers.

I work at a gaming center aswell, and we have been running daemon for years with no problem but we have recently installed the new version of daemon tools on our internet computers and now none of our removable USB Hard drives/ flash drives will get mounted (ie. get a letter assignment) as per other peoples post. Just wondering has their been a fix for this problem yet other than to uninstall daemon tools and the other related files?

Hi, I've got the same problem. I've uninstalled DT4. I've deleted sptd, sptd9409 and secdrv files from windows/system32/drivers. I've removed all registry entries relating to dtsci and sptd (as advised on another forum) but my flash drives or mp3 player still don't appear in my computer. A usb drive will appear in device manager assigned with the correct letter (k: in my case). I can populate it and the correct size is displayed. But it still wont appear in my computer or explorer. I dual boot Windows XP Pro sp2 and Windows Me. Everything is fine in Me presumably because I never installed DT on it. Any help would be greatly appreciated. RIZ

Press STart-> Run and enter 'diskmgmt.msc' (without '').
Search for your flash (usb) drive.
Does it have a letter? Try changing the letter.
Right click on it and press open. Can you access the drive now (with the open suggestion)?

Yes I can change the letter (still not visible in my computer)

Yes I can open it and get to my files:)

Wow! I can even drag and drop to/from it:D

Many thanks for your help,but I do still remain curious as to why this problem occurs and why I can't return to having removable drives visible in My Computer.

At least I can actually use them again without having to resort to Me (I don't know why I keep it really..........nostalgia??):rolleyes:

Thanks again. Steve

I sometimes have the same problem with my psp, but a usb flash drive and external usb hdd is working perfectly.
Did you install any StarForce protected game?

RIZ

I did find Starforce entries on my system about 3 months ago (I dont know which game they came from),but I used the Starforce Removal Tool to get rid of them.

My 40G USB works reliably on all computers on which I've ever tried it (30 at least), but I've found one on which it don't work.

On all other systems Device Manager reports drive as a SAMSUNG MPO0402H USB Drive.

On the computer in question it's not detected by XP (SP2 and up date). I've tried all of the USB ports (9 thereof), other "permanently" attached USB devices on the system are a scanner and a wireless network "adapter".

I can use a Kingston Flash Memory stick on the system, it gets allocated to drive H: (the system has two hard drives - C: & D:, a CD burner E: and a DVD Burner F:). I would have thought it would get allocated to Drive G:

Finally, the 40G drive has been used on this computer many times before.

This computer had DaemonTools installed, it was removed a few weeks ago as it was no longer required.

I've deleted the various drivers mentioned previously and removed related registry entries. The system still refuses to see the drive, but it is OK with flash drives.

I refomatted the 40G drive and changed it's name to no avail.
