Hello, the first time I bought a tablet (for work). I took it with the expectation that I would expand his memory with a Micro SD card, I bought a 128 GB card in advance (it works fine, through card readers, on the phone).
I got my new miracle, inserted a flash drive and ... rushed. He sees that the flash drive is stuck, but he refuses to work with it completely, is buggy, hangs, does not see its size, and cannot enter it. At the same time, the 4 gig flash drive sees excellent, the speed is 25-30 Mb / s, stable. A long fuss with the drivers did not lead to anything, I set it again automatically ... I went to dig in the BIOS, found the item (on the screen).
Putting PCI Mode instead of ACPI Mode, I achieved the definition of a flash drive and even its sane work. BUT! The speed of 5-10 MB / s, which, frankly, is not enough. Even through the adapter gives out 20 stably. The exFAT file system cluster size is 512 kb. Can anyone know a solution to this problem?
