Equipment: Acer Aspire 5535 Laptop
Originally running Vista Home Premium - no problem.
I have updated to W7 and now on W7 Ultimate SP1 32 bit

I can slot an DS card into the card reader and copy to/from with Explorer.

I then eject the device using Safely Remove Hardware and Eject Media icon in the rhs of the Task Bar.

I remove the card and then any other card slotted in is not recognised - including the original one. It does not appear in the Explorer window and is not accessible.

If I look on Device Manager, under Universal Bus Controllers, the eigth one down is USB Mass Storage Device and is showing an ! in yellow triangle. Right click on this brings up properties which tells me:

"Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)

To fix this problem, unplug this device from your computer and then plug it in again."

Well, if course I did remove the card but it don't see that :wacko:

If I reboot the LT this is cleared. If I watch Device manager whilst ejecting the card, nothing happens till I actually, physically take out the card when it updates the window to show the fault triangle.

I have checked for latest driver and am told it has the latest one. Other USB ports work OK.

HELP Please.

Thanks, Jerry

This is the first thing I would try.

Go into the Device Manager and delete the drives for all the USB drivers. Restart the computer. Windows will automatically re-install all the drivers after you restart your PC

Thanks Booh,

I have contacted Acer and was put on to a Microsoft Fix-it program which I ran to no effect. Awaiting further information from Acer.

I tried removing USB drivers. Removed the offending one and 3 more but when my mouse stopped working I stopped and rebooted. As you said, drivers re-installed: the USB Root Hubs and the offending USB Mass Storage Device reinstalled, but the USB MSD still failed to see the card removed.

Do you really mean I should remove all USB drivers including for instance the Standard Enhanced PCI Host Controller and Standard OpenHCD Host Controllers etc? Worried about not being able to re-start :whistle:

I'm wondering. The SD card has got a little difficult to slot in and remove - needs to be lined up well. Is it possible there is some physical damage in there meaning that the device does not detect that the card has been removed? I have never used force to get the card in.

Thanks, Jerry

I would just remove the USB drives for the USB ports. Sorry I didn't make that clear. About physical damage, I'm sure it's possible that it's physically damaged. I'll have to think about one. The thing is the PC is still recognizing the card you took out, which is some sort of OS issue.

OK.

So, now I know for certain that it is an OS/Driver problem, not damage to the card reader slot. How do I know?

To update from Vista to Windows 7 I purchased a new HDD. I installed that and then installed Win 7 meaning I still have the disk with up to date Vista.

I just re-installed that disk and the SD card reader works perfectly. I can eject the card, insert it again and it is installed and read/writable. Put the Windos 7 disk back and I have the problem.

What now ...................... :question: :unsure:

Let's try trouble shooting then.

It might just be that the one port is physically damaged.

Go to the Control Panel.

Click the arrow next the word 'Control Panel' in the search bar.

From the drop down menu, Click 'All Control Panel Items'

Click 'Troubleshooting'

Click 'Hardware and Sound'

Click 'Hardware and Devices' to start the trouble shooter.

Should have thought of this earlier.

Have you looked inside the port to see if there is any debris in it? Does the card work okay in another slot? Do you have another DS slot?

I should have made it clear earlier that it's not necessarily an OS issue, but it could be. It could be an OS or a physical issue. I'm not sure why it still show up when you reboot the computer.

Have you look at the card itself for damage?

Booh,

There's no muck in the card slot and no damage to the cards, I have tried several. I have a card adaptor to go in a standard USB port and all works OK there. There's only one SD card reader on the laptop.

You seem to have missed my point. The SD reader works OK with the old Vista (original Acer) drive (well it is a Western Digital HDD) but not with the Windows 7 HDD installed.

I ran the troubleshooter and it found 2 problems:

  • USB Mass Storage Device not working properly
  • Hardware changes might not have been detected

but was not able to solve them.

I saw that about it working with Vista. Please pardon my attention span. :)

The only thing that makes sense to me if it works in Vista, but not W7 is that it's a driver problem. I looked at the Acer website, but the are no new drivers for W7 upgrades. Apparently the drivers are compatible with both OS's.

There is only one download for PC's upgraded to W7, the 'Launch Manager'. I don't know what/if that has anything to do with the problem you're having, but it's worth a shot if you haven't already done so.

You can also try re-installing the Vista USB drivers from the Acer Website since they are apparently compatible with both OS's.

If that doesn't work, someone else around here will have more knowledge than I do and will help you out. Let me know if either of these help.

One other suggestion I keep seeing around here.

Try removing of your RAM sticks and reboot your PC. Check the driver to see if there are still problems. Do this for each RAM stick.

I've asked a hardware specialist to take a look at this thread. He has A LOT more knowledge than I do. He's not online right now, so please be patient.

If this card reader on your Acer laptop is the built-in type, please see the sample image below.

IF there is a SD/MMC device present, please right-click and choose Properties. Check device status and Policies option being used.

Use USBDeview to reset USB device drivers.

  • Download and extract (unzip) to a folder on your desktop.
    • 32-bit version
    • 64-bit version
    • To determine which version you need, click the start orb, right-click Computer, and select Properties. Look at the entry next to System Type.
  • In the taskbar area next to the clock, look for a icon that looks like a USB plug with a green check mark on it. Right-click it to bring up an 'eject' list. Eject the first device. After a moment it will say that the device is safe to remove. Remove it. Repeat this process for each item in that list.
  • Unplug any other USB device except the mouse.
  • Run the program. Click Edit > Select All.
    • Important! If you have a virtual machine emulator installed (such as Virtualbox, VMWare, Virtual PC, etc.), locate and deselect the USB entries created by those programs.
  • Click File > Uninstall Selected Devices. Your mouse will stop working. This is normal.
  • Plug in another USB device. Wait for the driver installation process to complete and then proceed to the next device.
  • Retest your problem USB device. Report your findings in your next reply.

Edit: Of course, finish jhayz's instructions first.

If it looks like I know what I'm doing, there's a pretty good chance the only reason for that is because
I once asked someone to run chkdsk /r and a BC Advisor smacked me in the back of the head.

Thank you all for your response.

Booh, I have looked on Acer support but to no avail :mellow: I'm still waiting response to my query. And thanks for passing my query onwards.

LucheLibre. Thank you for that. I may/may not avail myself as I am not a Techie, just a user with a little knowledge and we know where that leads ............ :blink:

Jhayz. Thank you for your suggestion. This found me a solution if not a fix. :thumbup2:

On looking at the Disk Drivers in Device Manager it tells me only that it is a Generic Multi-Card USB drive. This may be because of the W7 installation not being proprietary Acer. If I put the Vista HDD back in it may give me more information.

However, when looking at the Properties dialogue box for this device and going to the Policies tag there is a choice between Quick removal or Better Performance.

"Quick removal" allows ejecting the card without using Safely Remove Hardware (icon). I had always thought use of the Safely Remove Hardware process was mandatory to avoid damage to the card/device. Apparently not, unless the "Better performance" option is selected.

So, I can in fact insert / remove and re-insert the card successfully and with impunity now. :thumbsup:

Thanks all for the advices. Problem solved if not fixed.

Jerry

PS A fix may be to find the driver file on my Vista HDD and copy it to the W7 disk to replace the one there?? :unsure:
