QUMOX SD SDHC SDXC to CF Compact Flash Memory Card Adapter Reader Type I

This QUMOX CF Card to SD Card Adapter worked perfectly for converting two Creative Zen Vision M MP3 players with 30 GB hard drives to 128 GB Micro SD cards. (Note: The Creative Zen Vision M only recognizes ~120 GB – likely a firmware limitation.) I previously tried using a Kingspec 128 GB SSD, which had worked for converting two Zune 30’s and a Zune 80 in the past. The firmware installed successfully using the Creative firmware update utility, however, files (music or video) could only be transferred to the player in ~100 MB chunks. Any more than that, and the player would disconnect from my computer and need to be reset. Once loaded, the files would play correctly, but it was not feasible to transfer 60 GB of music and videos 100 MB at a time. I replaced the Kinspec SSD with the NOYITO CF to ZIF converter board, a QUMOX Compact Flash to SD card adapter, and a 128 GB micro SD card. The Creative Zen Vision M runs much faster with the SD card and seems to have better battery life.

Used this with a 1.8in to ZIF adapter to use flash instead of spinning rust, its a flawless, drop-in replacement for the drive, and you dont need the other cables that are included if you do it for the Creative Zen Sleek Photo my mp3 player now has 64GB of storage capability instead of the original 20GB without the need to worry about excessive shock and the longevity of the drive itself, as i can replace the SD card without problems 1. disassemble the device 2. remove the harddrive 3. put SD card into CF card 4. put CF card into slot 5. align existing ribbon cable, contacts towards PCB of adapter 6. reassemble the device 7. flash using the playsforsure on an XP or vista machine that doesnt have WMP11 or newer 8. put your music and photos onto the player as normal

lol it barely worked in windows as a removable device and passed through the sd card size but most bioses with the first form of "size query" ata commands refused to accept the reported sizes but now it shows up only as a device with no card inserted in windows even though it does the beep saying a device was just plugged in POS device since it reports being "removable" even though 99% of devices would work better if it reported "fixed"(removable media bit should ALWAYS be "0" in this adapters firmware or an easy to use tool to flip it) let alone it barely worked as a removable device and it doesn't comply with older ata specs (reports a drive size of >10tb in bios even though no sd card exists beyond 512GB which causes drive size query overflow and lack of proper bios detection (should report no more than 2.2tb to comply with MBR limitations for retro use)) recommend you do not buy this until they make drive size query report 2tb or less and removable media bit is forced to "0"(or allowed to be changed) ok the purpose of this device is for retro hard-drive replacements so working in windows as a fixed disk (removable media bit set to 0) isn't as important but setting it up prior to installing it in a retro device would be nice (making it show up as an actual internal device in firmware) so be warned you won't be able to natively partition in windows(it is possible to bypass this using a windows vm with direct disk access but that is too much work to set up solely for that) also it seems to do a very weird thing when used in a bios that tries to auto detect everything before even posting mainly seeming to report a random drive size greater than 14tb which some bioses seem to dislike (worked on a biostar am3 motherboard which is 64-bit but failed on a dell dimension 4600 which is only 32-bit) be warned your bios might not like it especially if it is a bios around the pentium 4 but only 32-bit likely will work fine in older or newer as full autodetect(large drive size causing detection failure) wasn't popular until about the p4 era but was picky until 64-bit cpus final edit: died when attempting to partition it for DOS use on physical hardware(complete lack of Bios detection) and then tried in a VM since it still worked in PIO mode (BIOS uses DMA/E-IDE modes) and it seemed to work during most of the install but also died at a specific DOS install point (maybe due to the seemingly 2mb ram buffer of the device filling up (found out from plugging into windows with no sd card)) this specific CF-SD device was a factory dud and it just never worked correctly maybe the brand is decent and I just got a flakey one but next time I go for a retro HDD It will be a direct SD-IDE Adapter(large storage) or a native CF-Card(Dos small drive usage)

This is a great adapter. However, you should know, it works perfectly with sd cards, and micro as card adapters, but canons W-E1 Ed Wi_Fi adapter DOES NOT WORK WITH THE CARD. It may work differently on other full frames, as I have the canon 5ds. Just be aware. Yes you could swap the sd card with the Wi_Fi adapter (Sd card goes in CF adapter, Wi_Fi goes in as slot) and it can transfer those images off of the cf adapter. Great product, just wasn’t expecting it to not work in the cF adapter.

Works well to use an SD card in an old iPod. Fair warning on one of the caveats of this adapter; if certain patterns are present in the MBR, it will NOT pass through the partition table and instead provide a fake partition table. This misfeature is likely to allow certain cameras that misuse CF cards to function correctly. This behavior can be circumvented by writing a zero byte to the very beginning of whatever SD card you put in the thing using a hex editor or dd, overwriting what was probably the value 0xEB. You have to do this outside of the adapter, though - it's not possible to do in disk mode on an iPod, for example.

This adapter does not support 8-bit PIO mode, as required by the CompactFlash specification. Therefore, it might not work in all devices. I wanted to use this for a personal project that requires a minimal CompactFlash interface, and it fails to read correctly. I may, however, be the only person affected by this, as I imagine most devices would use the full 16-bit interface. I think I may be stuck using actual CompactFlash cards. It is a shame, as I don't think it would have taken much effort to add this feature. My SD card fit in snugly, and the device apparently works fine for 16-bit PIO mode, which in my application only reads half of the data, as I am trying to suck a 16-bit milkshake through an 8-bit straw. I did not test the faster DMA modes as my application can't support them. Removing the SD card takes a bit of effort, as there is nothing to really grab onto. I used a fingernail to slide it out enough to grab and pull out the rest of the way. To summarize, it may be a fine product for most uses, just not mine.

Speed tests show about half the speed the SD card achieves without the adapter. Once the buffer fills on my camera it slows to about one frame per second, didn't attempt video. I keep it in my bag as a cheap backup but use a true CF as my primary. I recommend using a true CF card if you want speed, but if you have a bunch of SD cards laying around it's an affordable way to make use of them, if you don't mind the drop in speed.

Instead of purchasing multiple 32GB CompactFlash cards for $30 each, I was able to purchase this adapter and 3 32GB SD cards for the same price. As a side bonus, I no longer need an CF reader either! BE AWARE - While you can put an SD Card up to 128GB in this adapter, you will still need to use SD Card sizes that are compatible with your camera!
