Rob, what do you see in your device manager? Type “Device Manager” in the Windows search area.  Under Disk Drives, you should see something like the picture below.   If not maybe a  Triangle with an “!” inside  it.  Right click on it, and it should give you the option to search for a driver..
^They quit releasing new games for the GC, but they’re still producing the GameCube system as well as all first-party games released for it. Also, Nintendo hasn’t released ANY official information saying they discontinued production of the GC. The production info in the Game Daily interview is completely false, it was confirmed that Perrin Kaplan is wrong again. And so, the GC is still in production, shipped to stores, and sold worldwide and that’s a fact.

A £5 SD card from a supermarket will give you the same results as using the latest generation of card from Lexar, SanDisk or Samsung. The difference, however, is that the cheaper card may do it much more slowly, be less reliable, have fewer backup measures, different components, and, in terms of memory card data recovery, may not be such a wise choice if things go wrong and your images go missing.
Home consoles now commonly use hard disk drive storage for saved games and allow the use of generic USB flash drives or other card formats via a memory card reader to transport game saves and other game information, along with cloud storage saving, though most portable gaming systems still rely on custom memory cartridges to store program data, due to their low power consumption, smaller physical size and reduced mechanical complexity.
I ordered the IOGEAR SD/MicroSD/MMC Card Reader/Writer GFR204SD and got it in the mail about three days after ordering [impressive]. As some other reviewers have noted, it does feel a little flimsy, and care should be taken to insert and remove it AS STRAIGHT AS YOU CAN from whatever device you use it in, especially when it’s a very tight fit into the USB port.
The GameCube is unable to play games from other Nintendo home consoles, but with the Game Boy Player attachment, it is able to play Game Boy, Game Boy Color, and Game Boy Advance games. The GameCube’s successor, the Wii, supports backward compatibility with GameCube controllers, memory cards, and games. However, later versions of the Wii – including the “Family Edition” released in 2011 and the Wii Mini edition released in 2012 – dropped support for all GameCube hardware.[56][57][58]
The above types of memory cards are usually associated with consumer devices, such as digital cameras, smartphones and tablets. The cards come in varying sizes, and storage capacities typically correspond directly to their price.
I had the same issue on my HP laptop after upgrading to windows 10. I was able to fix the issue by uninstalling the SD card reader, restarting my computer, and then running the device troubleshooter with the SD card placed in the card reader slot. Make sure the card is placed in the card reader device while running the troubleshooter. That worked for me.
I bought this to run on my Droid Razr Maxx HD phone. Worked fairly smoothly at first. Then in the two days prior to total failure, it kept unmounting from my phone. After that nothing. Won’t read on my phone or pc at all. Dead in the water. I like the price, the capacity, and the brand name. Wish I could rate it higher, but when something fails so badly, there is no value in it or any way I could give it a higher overall rating.
Reading from NOR flash is similar to reading from random-access memory, provided the address and data bus are mapped correctly. Because of this, most microprocessors can use NOR flash memory as execute in place (XIP) memory, meaning that programs stored in NOR flash can be executed directly from the NOR flash without needing to be copied into RAM first. NOR flash may be programmed in a random-access manner similar to reading. Programming changes bits from a logical one to a zero. Bits that are already zero are left unchanged. Erasure must happen a block at a time, and resets all the bits in the erased block back to one. Typical block sizes are 64, 128, or 256 KiB.

UHS-II uses an additional row of pins to transfer data faster than UHS-I. Because of that extra row of physical pins, you can use a UHS-II card with a UHS-I camera, and a UHS-I card with a UHS-II camera, but you won’t get UHS-II speeds unless both camera and card support it. Likewise, to get those transfer speeds from your SD card to your computer, both the card and card reader must support it. Only high-end cameras can take advantage of UHS-II SD cards right now, but we expect this to change. In February 2017, the SD Association also introduced UHS-III (PDF) to provide further support for 360-degree, 3D, 4K, and 8K media content, but we expect it will take a year or two before we see memory cards and devices that support the new interface.
Hewlett Packard Enterprise and SanDisk are partnering on a similar initiative to develop storage-class memory based on SanDisk’s nonvolatile resistive random-access memory (ReRAM) technology, which would be used to design a new class of SSDs.
I got the same e-mail. I think it’s safe to say that they’re still producing the system, because they did say they don’t have any immediate plans to discontinue sales and distribution of the system. In other words, they have no plans right now to make the GC one of their non-current (no longer available in stores/getting anything new) systems like their 3 consoles that came before it.
A fairer and more recent system is the ‘class rating’. The SD Association created the speed class rating test which focuses on finding the absolute minimum data transfer rate of SD/SDHC/SDXC cards, as opposed to a sustainable rate.
CompactFlash drive technology: The forerunner to the SD card, the original CF cards were designed on the Parallel Advanced Technology Attachment standard and were no larger than a matchbook. CF cards included a microcontroller and were used as flash memory storage for high-resolution photography. CF and SD cards lack built-in USB computer device connectivity.
Kingston Card Readers quickly transfer all your data – photos, videos, music etc.– so you can wait less and do more. They support a wide variety of formats, including microSD, microSDHC, SD, SDHC, SDXC and CompactFlash.
NOR and NAND flash memory differ in architecture and design characteristics. NOR flash uses no shared components and can connect individual memory cells in parallel, enabling random access to data. A NAND flash cell is more compact and has fewer bit lines, stringing together floating gate transistors to increase storage density.
Commonly found on the market are mislabeled or counterfeit Secure Digital cards that report a fake capacity or run slower than labeled.[90][91][92] Software tools exist to check and detect counterfeit products.[93][94]
In applications that require sustained write throughput, such as video recording, the device might not perform satisfactorily if the SD card’s class rating falls below a particular speed. For example, a high-definition camcorder may require a card of not less than Class 6, suffering dropouts or corrupted video if a slower card is used. Digital cameras with slow cards may take a noticeable time after taking a photograph before being ready for the next, while the camera writes the first picture.
If your camera uses SD cards but your laptop lacks a card reader (or it has one, and you’re unimpressed by its speed), you’ll need a separate card reader that hooks up to your laptop via USB-C or USB-A to transfer your photos and videos.

This microSDHC card holds 8 billion bytes. Beneath it is a section of a magnetic-core memory (used until the 1970s) that holds eight bytes using 64 cores. The card covers approximately 20 bits (2 1/2 bytes) This SD card’s storage is approximately 3.5 billion times greater areal density.
PC Cards (PCMCIA) were the first commercial memory card formats (type I cards) to come out, but are now mainly used in industrial applications and to connect I/O devices such as modems. Since 1994, a number of memory card formats smaller than the PC Card arrived, the first one was CompactFlash and later SmartMedia and Miniature Card. The desire for smaller cards for cell-phones, PDAs, and compact digital cameras drove a trend that left the previous generation of “compact” cards looking big. In digital cameras SmartMedia and CompactFlash had been very successful[neutrality is disputed]. In 2001, SM alone captured 50% of the digital camera market and CF had captured the professional digital camera market. By 2005 however, SD/MMC had nearly taken over SmartMedia’s spot, though not to the same level and with stiff competition coming from Memory Stick variants, as well CompactFlash. In industrial and embedded fields, even the venerable PC card (PCMCIA) memory cards still manage to maintain a niche, while in mobile phones and PDAs, the memory card has become smaller.
As of 2013, V-NAND flash architecture allows read and write operations twice as fast as conventional NAND and can last up to 10 times as long, while consuming 50 percent less power. They offer comparable physical bit density using 10-nm lithography, but may be able to increase bit density by up to two orders of magnitude.[24]
Getting yourself in a memory card muddle and not sure which card to buy? We look at memory card speeds and the fastest memory card on the market to help explain the differences so you can find out what’s the best card for you.
xD cards are simply 18-pin NAND flash chips in a special package and support the standard command set for raw NAND flash access. Although the raw hardware interface to xD cards is well understood, the layout of its memory contents—necessary for interoperability with xD card readers and digital cameras—is totally undocumented. The consortium that licenses xD cards has not released any technical information to the public.
Works very well for a third party GC memory card. Used it for about a week and not a single game file has corrupted. If you’re looking for a 1019 block GC memory card but don’t want to shell out the $20, this is what you’re looking for.
CompactFlash (CF) cards offer very high storage capacities and fast processing times. They were first introduced by Sandisk in 1994 and were widely used, but now they are usually only found in the most advanced DSLRs. Last year Canon chose CompactFlash as the recording media for use in its new lineup of professional high definiton (HD) video cameras.

I’ve long been a fan of Sandisk, and have faithfully used their compact flash memory cards in all my digital cameras, so imagine my surprise to have two 16 GB and two 32 GB cards fail in two different Samsung Galaxy SIII phones so far, taking all data with them. The cards cannot be accessed or formatted, either in the phone or on the computer. I’ve finally contacted Sandisk support, but after reading a lot of review on the web concerning this issue (and trying all the various workarounds posted), I’m not confident that Sandisk will be able to help me. There frankly should be NO WAY for an SD interface to make a card unusable, short of physically destroying it with overvoltage, period. I’m an embedded systems engineer (30+ years experience) and there is NO EXCUSE for Sandisk cards failing like this, unless the phone is doing something evil electrically to them. Please beware, and back up your files often, because it WILL FAIL eventually.
When executing software from NAND memories, virtual memory strategies are often used: memory contents must first be paged or copied into memory-mapped RAM and executed there (leading to the common combination of NAND + RAM). A memory management unit (MMU) in the system is helpful, but this can also be accomplished with overlays. For this reason, some systems will use a combination of NOR and NAND memories, where a smaller NOR memory is used as software ROM and a larger NAND memory is partitioned with a file system for use as a non-volatile data storage area.
A joint development at Intel and Micron will allow the production of 32-layer 3.5 terabyte (TB) NAND flash sticks and 10 TB standard-sized SSDs. The device includes 5 packages of 16 × 48 GB TLC dies, using a floating gate cell design.[66]
PCIe-based SSDs are designed around Peripheral Component Interconnect Express, a high-speed expansion card format that connects a computer with its attached peripherals. PCIe has a point-to-point architecture, allowing each device to connect to a host via its own serial link, rather than by sharing a network bus. By virtue of this direct connection, PCIe SSDs are generally rated to deliver higher performance than server-based Serial Advance Technology Attachment (SATA), Serial-Attached SCSI (SAS) or Fibre Channel (FC) SSDs.
If you use a camera or cards that support UHS-II speeds, we recommend the Verbatim USB-C Pocket Card Reader. The Verbatim had read and write speeds of 227 MB/s and 219 MB/s, respectively—around 2.5 times the speed of our top pick—but it cannot read multiple cards at once. It also lacks a CF card slot (so high-end DSLR owners may want to look at our pick for traditional USB ports, along with an adapter if they need USB-C compatibility) and an indicator light, but it costs around the same price as our top pick and comes with a one-year warranty.
I haven’t really been able to find reviews for this reader that thoroughly address the issue of car connectivity [and I’ll admit I gave a few a quick once-over and was just trying to key in on a few words]. I bought this item on a gamble because of that. I figured that for the price, if it wouldn’t work with my car, I can always find another use for it, with barely a dent in my wallet.
Flash memory architecture includes a memory array stacked with a large number of flash cells. A basic flash memory cell consists of a storage transistor with a control gate and a floating gate, which is insulated from the rest of the transistor by a thin dielectric material or oxide layer. The floating gate stores the electrical charge and controls the flow of the electrical current.
