Sd Slot Not Reading Sdhc
When I insert an sd card in the reader, the pc doesn't do anything. The card doesn't show up in explorer or drive manager. The SD should show up in device manager as a SD host controller. Do you have a smart card reader? Edit: Yeh, the base system device is the problem. SD Card not reading. If your computer's internal card reader works with 2GB (or lower) SD cards but fails to read a 4GB (or higher) SDHC card, then the computer's internal reader is not SDHC compliant. This same logic also applies to digital cameras, if the digital camera reads 2GB (or lower) SD cards but fails to read a 4GB (or higher) SDHC card, then the digital camera is not SDHC compliant.

(Solved) - SD/MMC card reader not working !
(15 posts)Not sure if this is the right place to put this question but here we go :
HP Pavilion Slimline
Running Vista Home Premium SP2 32bit
Have had for some time now a problem with all my, SD/Mini/MMC/RS/Plus/Mobile, card slot it just won't read anything of any kind of SD/MMC card, tried everything i can and can't seem to get it to work could anyone please help ?
Think maybe i need to update the drivers or something, maybe someone could point me in the right direction or explain in plain english !
Thanks in advance !
Does the little green light by the card reader go on when you stick the card in? On some systems, the power to the reader is cut off if you use 'safely remove' before you pull out the card. Safely Remove must not be used - use 'Eject' instead. But when the power is off, it usually comes back with a reboot.
Does the card reader show up in Device Manager? How is it attached, USB, Firewire, other? Can you see the empty removable drives in the 'Computer' folder?
m8 im currently uploading a video to utube on how u might fix it
here it is: http://www.youtube.com/watch?v=gjBE9IkYdbo
is there is a error or sommat when doing it plz tell me!
Hi there guys got this sorted, so thanks for all the support, what i did was,
opened control panel,
system and maintenance,
update device drivers,
disk drives,
then uninstalled each individual Generic flash /usb driver,
then rebooted
and bobs your uncle fannys your aunt and hows your belly for spots !
FiXED and Sorted !
Once again thanks for the help and support but at least if someone else has this prob they can try this method !!!!!!!
The drivers for my SD, MMC 's etc, come via Windows Updates.
u followed my instructions w00t!!!!!(sort of lol) it took me 3 hours making that vid and posting it!!!!
gratz
Nice video. But why did you not use a mic for the instructions rather than typing them into a notepad? And did you edit the video with WMM? Just curious.
Actually i didn't follow your instructions or watch your vid i just worked it out myself,but if i'd known there where instructions or vids i might of got it sorted quicker !
Thanks Anyway !!
hello whs... tbh i couldn't find my microphone and no i didnt itz straight of hypercam :D
I did what it shows in the video and now when i plug in my card the light comes on, but nothing else happens. i click on a drive ( H,J,I,) and my screen goes white and computer says not responding. what now?
wiggles hi. Please start a New Topic for your problem. This one is very old, and is now closed.

There are three main types in the SD memory card family. SD, SD High Capacity (SDHC™), and SD Extended Capacity (SDXC™). This article details the different specifications of all three types of SD memory cards and the speed class ratings and compatibilities that are different with each type.
Click here to jump straight to Speed Class & UHS Speed Class Ratings
Click here to jump straight to the Compatibility Summary
Additional Reference: SD Assocation Consumer Information
SD capacities range from 128MB to 2GB
Default Format: FAT16
SD cards will work in all host devices that support SD, SDHC, or SDXC
SD High Capacity (SDHC™) card is an SD™ memory card based on the SDA 2.0 specification.
SDHC capacities range from 4GB to 32GB
Default Format: FAT32
Because SDHC works differently than standard SD cards, this new format is NOT backwards compatible with host devices that only take SD (128MB - 2GB) cards. Most readers and host devices built after 2008 should be SDHC compatible.
To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.)
SD Extended Capacity (SDXC™) card is an SD™ memory card based on the SDA 3.0 specification.
SDXC capacities range from 64GB to 2TB
Default Format: exFAT
Because SDXC uses a different file system called exFAT and it works differently than standard SD cards, this new format is NOT backwards compatible with host devices that only take SD (128MB to 2GB) or host devices that only take SDHC (4GB to 32GB). Most host devices built after 2010 should be SDXC compatible.
To ensure compatibility, look for the SDXC logo on cards and host devices (cameras, camcorders, etc.).
NOTE: Internal card readers on laptops from 2008 and prior may NOT support SDXC cards. SDXC cards will work in SDHC compatible readers (not SD readers) if the computer OS supports exFAT. For more information on exFat see: Operating Systems that support the exFAT File System
Ultra High Speed, Phase I (UHS-I) bus design for SDHC and SDXC cards was added in SD spec 3.0. This is a design enhancement to increase the performance of SDHC/SDXC cards.
UHS-I specification defines two bus architecture options for up to 50MB/s (UHS-50) and 104MB/s (UHS-104) data transfer rates. These are theoretical maximum limits and actual maximum performance for a specific card is defined on it label or in advertising.
UHS is an enhancement to the original SD interface specifications. Host devices will obtain the UHS maximum speed when both the card and host device support UHS. Otherwise, the host device and card will use the slower SD maximum speed obtainable.
There is no compatibility problem using a UHS card with a non-UHS device.
Ultra High Speed Phase II (UHS-II) bus design for SDHC and SDXC was added in SD spec 4.0. This is an additional design enhacement with connector interface modifications to increase performance.
UHS-II specification defines bus architecture for options of 156MB/s and 312MB/s. Manufacturers implemented the 312MB/s option in memory cards. These are theoretical maximum limits and actual maximum performance for a specific card is defined on the label or in advertising.
Host devices will obtain the maximum UHS-II speed when both the card and the host device support UHS-II. Otherwise, the host device and card will use the highest compatible UHS-I or SD bus speed.
There is no compatibility problem using a USH-II card in a UHS-I or non-UHS device.
Speed Class & UHS Speed Class Rating
Speed class ratings define a minimum guaranteed speed of SDHC/SDXC cards. Speed class rating is important for HD video mode or camcorders, where the device is actually saving a steady stream of data. The resolution and format of the video determines the amount of steady stream data. You should consult your camera user manual for minimum speed class requirements for HD video modes.
Speed Class (SD Bus)
Class | Minimum Speed |
2 | 2MB/s |
4 | 4MB/s |
6 | 6MB/s |
8 | 8MB/s |
10 | 10MB/s |
UHS Speed Class (UHS Bus)
UHS Class | Minimum Speed |
1 | 10MB/s |
3 | 30MB/s |
