Hi, Download and install the Realtek Card Reader Win 10 driver for your laptop. Select Windows OS, then Version Win 10, Click Update. Scroll down to Driver- Storage and click on + sign. HP Envy 15 X360. Just recived 2 days ago my new HP Spectre x360 - 13-ae006nj The Micro sd card reader is not working. When i insert micro sd card there is popup sound that new device is insert (like when i pluged usb) but i cant find the card anywhere and see the files in the card.
- Dec 30, 2019 SD card slot not working? Everything from start up onward is lightening fast, the USB ports all work as does the DVD re-writer. But even though I am almost certain that the SD card slot has never been used as it still has the factory Dell blank inserted, I cannot get the laptop to recognise an SD card, and I have tried several that I know are.
- The laptop makes a sound (as when you connect a peripheral device) but doesn't autoplay. When I go to Start / Computer, I don't see any Removable Disks that represent the SD/MMC slot. BTW, FYI, I have.
- 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.
History
In 1997, Siemens AG and SanDisk developed the MMC card using Toshiba's NAND-based flash memory. As it uses NAND based flash memory, it is much smaller in size than the IntelNOR-based memory; such as CompactFlash. Originally it used a 1-bit serial interface, but with the new architecture, now it can transfer 4 or 8 bits at a time.
After the release of MMC cards most of the portable music players started using MMC cards as primary storage. But the music industry was skeptical about the use of MMC, as MMCs would allow easy piracy of music. So, Toshiba added encryption hardware in existing MMC and named it Secured Digital or SD card. This allowed Digital Rights Management(DRM) for the music. Matsushita, SanDisk, and Toshiba jointly developed, next generation secure memory card called the SD Memory Card. SD cards provide both an SDMI-compliant (Secure Digital Music Initiative) high-level of copyright protection and high-density memory capacity. Today, in many areas, MMC are being replaced by SD cards. The only reason why some devices continue using MMCs are because of their comparative lower cost than SD cards.
Size
The size of a standard MMC card is 24 mm x 32 mm x 1.4 mm while that of a SD card is 24 mm × 32 mm × 2.1 mm. So from the size comparison, we can see that SD cards are much thicker than the MMC cards, 2.1 mm against 1.4 mm.
Interoperability
Because of the size similarity, MMC cards can be also used in the standard SD card slot, but the reverse is not true.
Storage Capacity
MMCs are currently available in sizes up to 4 GB and 8 GB models. As of September 2007, SD cards were available in sizes from 8 MB to 16 GB. A few companies have announced SD cards with 32 GB also.
Usage
Amongst digital cameras, companies that use SD cards include Canon, Epson, Casio, HP while Epson and some models of Nikon and Sony cameras use a MMC card and compact flash memory depending on the model. In Mobile phones, Nokia uses both MMCs and SD cards which vary according to the model. Samsung and Motorola phones use SD cards. Amongst gaming consoles, Nintendo Wii and Sony Playstation 3 use SD cards while Xbox 360 uses a memory unit.
Different versions

Apart from the standard MMC there are other versions available also. They are Reduced-Size MultiMediaCard (RS-MMC), dual voltage MMC card (DV-MMC), MMC plus, MMC mobile, MMC micro and MMC secure.
RS-MMC has a size of 24 mm × 18 mm × 1.4 mm. It was released in 2004. RS-MMCs are smaller MMCs and use a mechanical adapter to elongate the card. It can be used in any MMC (or SD) slot and they are currently available in size up to 2 GB.
DV-MMC cards can operate at 1.8 V and the standard 3.3 V. Working at lower voltages reduces the card's power consumption, and thus used in mobile devices. In 2005, version 4.x of the MMC standard launched, to compete with SD card. This version is known as MMCplus (with the full size) and MMCmobile (with reduce size). These cards run at a higher clock speed (26MHz, 52MHz) than the original MMC (20MHz) or SD (25MHz, 50MHz) and it also has 4 or 8 bit wide data buses. Though these cards are fully compatible with MMC standard, but to use it, one needs to update the software.
MMC micro is a micro-size version of MMC and it has a dimension of 14 mm × 12 mm × 1.1 mm, it is smaller and thinner than RS-MMC. It also supports dual voltage, and backward compatible with MMC, and also can be used in full-size MMC and SD slots with a mechanical adapter.
SD cards are normally available in two more versions. They are miniSD and microSD. MicroSD is the smallest memory card available commercially. The size is 15mm × 11mm × 0.7mm. It is about 25% of the size of an SD card. With the help of adapters it can be used in those devices which are meant for SD, miniSD, or Memory Stick Duo cards; but they are not universally compatible.
MiniSD card was launched in 2003 and has ultra-small form factor extension to the SD card standard. These cards were designed especially for mobile phones; and packaged with a miniSD adapter through which it can also be used in devices that equipped with a standard SD Memory Card slot.
SDHC (Secure Digital High Capacity, SD 2.0), an extension of SD card, allows larger capacity, more than 2 GB. It uses the FAT32 file system which supports partition sizes greater than 2 GB. SDHC card has 3 different classes depending on their speed. Class 2 has speed of 2 MB/s, class 4 has 4MB/s, and class 6 has 6 MB /s. SDIO is another standard for SD card, which stands for Secured Digital Input and Output.
