Review on 📷 QUMOX SD to CF Memory Card Adapter Reader: Wi-Fi Enabled for SDHC, SDXC, and WiFi Cards by Christopher Kanter

lol barely worked on windows as a removable disk and went through the size of the sd card but most bios with the first form "size query" ata command refused to accept It reported sizes but now it just shows up as a device with no card inserted in Windows, although there is a beep saying the device has just been connected to a POS device as it reports it is "removable" is, although 99% of devices would work better if it reported "fixed" (removable media bit should ALWAYS be "0" in this adapter's firmware, or an easy to use tool to undo it) , not to mention that it barely worked as a removable device and doesn't conform to old ATA specs (reports a disk size >10TB in BIOS even if there is no SD card larger than 512GB, resulting in disk size overflow and lack of proper detection ia BIOS (should report no more than 2.2TB to meet MBR limits for retro usage) it is recommended not to purchase this device until they report create a disk that requests a disk size of 2TB or less and set the removable media bit to "0 (or allowed to change), okay, the purpose of this device is to replace old disks, so it's not that important to use Windows as fixed drive (removable media bit set to 0) but it would be nice to set it up before installing it on a retro device (so that it shows up as an actual internal device in the firmware), so keep that in mind that you can't natively partition in Windows (it's possible to do this with a Windows VM with direct disk access, but that's too much work to set up just for that), it also seems a very strange thing to do, we When using it in a bios that tries to autodetect everything which seems to report basically a random size even before posting Drive over 14TB which some bios don't seem to like (works on Biostar AM3 motherboards with 64 bit, but not on Dell Dimension 4600 with only 32 bit). Note that your bios might not like it, especially if it's a bios around a Pentiu m 4, but only the 32-bit version will probably work fine in older or newer versions, due to full auto-detection (big disk size, causing detection to fail) was not popular before the p4 era. but was picky about up to a 64-bit processor. Final edit: died trying to break this to use DOS on physical hardware (complete lack of bios detection) and then tried on a virtual machine as it was still running in PIO mode (BIOS uses DMA/E- IDE modes) and it seems to have worked for most of the install, but also died at some point in the DOS install (possibly due to the device's 2MB RAM buffer filling up seems (finds it out when connected to Windows without an SD card)). A certain CF SD device was a factory defect and just never worked properly, maybe the brand is decent and I just got an unreliable one, but next time I go for a retro hard drive it will be a straight SD IDE adapter (large memory) or your own CF card (using a small DOS disk)
