blk_update_request：I/O 錯誤，dev fd0，扇區 0
我最近開始注意到
blk_update_request: I/O error, dev fd0, sector 0在我用作伺服器的第二台執行 Arch Linux 的電腦上出現了一些錯誤。這始於我搬進新公寓時不得不重新啟動電腦。我有以下/etc/fstab配置：# # /etc/fstab: static file system information # # <file system> <dir> <type> <options> <dump> <pass> #UUID=94880e53-c4d3-4d4d-a217-84c9ac58f4fd /dev/sda1 / ext4 rw,relatime,data=ordered 0 1 #UUID=c1245aca-bbf7-4813-8c25-10bd0d95631e /dev/sda2 none swap defaults 0 0 #UUID=94880e53-c4d3-4d4d-a217-84c9ac58f4fd /dev/sdb1 /media/marcel/videos auto rw,user,auto 0 0所以我的主硬碟安裝到
/我的外部硬碟安裝到/media/marcel/videos. 問題是重新啟動後，我的外部驅動器得到了/dev/sda，而我的內部驅動器得到了/dev/sdb。據我所知，電腦啟動良好，直到我查看了/media/marcel/videos哪個是/. 現在我拔掉了外部驅動器，我只是想對我的主驅動器進行故障排除。相關

似乎核心錯誤地將某些設備檢測為磁片，或者只是創建了一個不存在的引用，因為您的機器沒有真正的磁片驅動器。因此，這些與您的硬碟驅動
blk_update_request器fd0完全無關。許多磁碟管理程序fdisk喜歡列舉所有可用的塊設備，並且fdisk確實命中了磁片模組，並且這些消息開始出現在您的 dmesg 中。由於您的機器沒有磁片驅動器，因此建議您刪除
floppy核心模組並將其列入黑名單，這樣以後就不會打擾您了：sudo rmmod floppy echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf然後添加
/etc/modprobe.d/blacklist-floppy.conf到/etc/mkinitcpio.confFILES 變數，這樣mkinitcpio -p linux做 initramfs 也不會載入它。因此，下次重新啟動後，它不會出現並弄亂您的穩定配置。
