Acer Aspire One Netbook SD Card Reading issue

May 19, 2010 at 04:34:07
Specs: Windows XP Pro, 1.6 GHZ
I have an aspire one with a card reader and an SD expansion slot. Neither recognise the SD card in My computer. But in both it makes a recognition sound when I insert the card while windows is running. I reinstalled the card reader drivers from the acer website without success. Any ideas? Thanks a lot in advance for any feedback.

mmm - how large is the SD card (capacity)?

On some laptops (especially older models) there is limit on the size of card they can read... Possibly you are running into a similar limit with the netbook?

Have you checked with the manual and/or Acer tech support site(s) to see what the specs/limits are?

Hi, there is no mention of an SD card size limit in the manual.

I have inserted a Kingston 4GB one.

Thanks for the assistance!

If you were to test with a smaller capacity SD - say upto 2Meg would it also fail to detect?

Also if you were to use a USB-SD adapter what happens then?

My (relatively elderly) Aspire 1689 etc. can only handle upto 512 in its slot; but is OK to at least 4Gig with a usb-sd adapter....

This is a brand new acer model. I do not think that the capacity is not supported, rather some or other driver malfunction. Thanks for the thoughts though!

Where did you get a brand new model with WinXP pre-installed?

I bought it at a local South African Telecom Shop which had the product with XP Home pre-installed. Tried the SD reader thereon - no success. Replaced it with XP Professional and also no success.

Sorry I missed the model before.

The types of removable media that units supports are as follows:

Multi-in-1 card reader
Supporting Secure Digital (SD) Card, MultiMediaCard (MMC), Memory Stick (MS), Memory Stick PRO (MS PRO), xD-Picture Card (xD)

If a card is not formatted and partitioned it will not show up in My Computer.

Go to Disk Management and see if the card shows there. If so, partition and format it from there.

Thanks for the effort of responding! This may be - and probably is - a stupid question, but how do I access the disk via disk management? Is it an external software or does it come with windows xp pro?

It is part of WinXP.

Go to Control panel> Manage> Storage> Disk Management.

That is from memory. I think those are all the steps.

Disk Management is part of Manage.

I went to control panel.

Administrative tools.

Computer Management.


Disk Management.

The only devices shown are 2 partitions of my Harddrive.

No sign of the SD card...

Then go to Device Manager and see if your card reader is showing there.

It showed for a second but then disappeared not to be seen again. What to do?

Was that with a card inserted or without? Try without.

No sign of the device/drive with or without the disk put in...

Are you sure you are inserting the SD card fully? It should lock in place and you should need to depress it further in order to remove it.

Since this thread started I have purchased an Acer Aspire One Netbook. The unit came with Windows 7 starter in my case.

The card reader is shown in my Device Manager under Universal Serial Bus Controller as "ENE mass storage controller" Only after a card is inserted. Not sure which listing it is under System devices.

So, If you have played around with the drivers you need to verify you are installing the correct drivers for WinXP.

Your SD card should appear in Disk Management as Disk 1 removable. It may or may not be partitioned and formatted.

The insertion is definitely not a problem. It clicks in and I need to press it in further to get it out again.

Went to Universal Serial Bus Controler and there are no error reports.

I really dont know what to try any more.

I guess I'll just have to pay Acer representatives a visit.

Thanks again for all the help!

If the card reader is not configured there probably wouldn't be any error report.

Do you have a listing in the USB controller section for a mass storage controller or not, when a card is inserted?

What about a Disk 1 removable in Disk Management?

Verify you downloaded the right drivers. Below is a link. There are MANY different Aspire One models.

As a first step, I think it would be a good idea to check out that particular SD card in another PC.

If it works, then at least you have eliminated possible issues with the card itself. If it doesn't work, then... the problem is the card, not missing drivers, etc.

Thanks for the insightful comments!

I will test the card in another PC once I get the chance to do so.

I have observed the following:

There in one USB Mass storage device in the device manager

When I insert the SD card into the slot, for a moment (a few seconds) another 'USB Mass storage device' appears.

Then it disappears. (the typical XP sound mechanism of USB insertion and de-sertion also takes place)

I will follow up once I have tested the card.

In that case I suggest removing the Mass storage device that does show and rebooting. That assumes you have no external or flash drives connected.

Some of these cards can - and occasionally do - act up; and may not be detected etc. in a given system - regardless of brand of card - and the system it's used in...

You may have one of them... They churn thesse things out by the bucket load; so it's inevetiable the odd dodgy one will exist at times?

As "OtH" advises - test the card in another working system - if only to confirm the card is OK (or not....).

Most older built in card readers will NOT read more than 2 GB card.
I would suggest an external USB reader, they are real cheap anymore and will work. I know, because I use them

Some HELP in posting on plus free progs and instructions Cheers

Acer Aspire One is a current production unit. It should read larger cards. I think the issue is that there are more than one instance of the card reader installed.
