創(chuàng)建文件，打開(kāi)文件都正常，444個(gè)字節(jié)的數(shù)據(jù)要寫(xiě)入文件；“if(GetCh376IntStatus() == USB_DISK_WRITE)”第一二次都是0x1E，第三次是0x14,“BlockLen=WriteReqDataBlock(Buf);”第一次返回0xFF，第二次返回0xBD，合計(jì)也是444字節(jié),這些都顯示向文件寫(xiě)數(shù)據(jù)是成功的，但是在PC上打開(kāi)文件看不到寫(xiě)入的數(shù)據(jù)。請(qǐng)專(zhuān)家指導(dǎo)，謝謝！
另：文件的創(chuàng)建時(shí)間怎么解決？
