我正在努力解决 USB 上的可用空间问题
sudo f3probe --destructive --time-ops /dev/sdd
节目
Good news: The device `/dev/sdd' is the real thing
Device geometry:
*Usable* size: 14.65 GB (30728832 blocks)
Announced size: 14.65 GB (30728832 blocks)
Module: 16.00 GB (2^34 Bytes)
Approximate cache size: 0.00 Byte (0 blocks), need-reset=no
Physical block size: 512.00 Byte (2^9 Bytes)
Probe time: 4'36"
Operation: total time / count = avg time
Read: 547.7ms / 4814 = 113us
Write: 4'33" / 4192321 = 65us
另一方面 df -h 输出
Filesystem Size Used Avail Use% Mounted on
/dev/sdd 1,9G 1,4G 442M 77% /media/miki/05DB-E2AB
file -s /dev/sdd
/dev/sdd: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "mkfs.fat", sectors/cluster 8, Media descriptor 0xf8, sectors/track 32, heads 64, sectors 3815136 (volumes > 32 MB), FAT (32 bit), sectors/FAT 3720, reserved 0x1, serial number 0x5dbe2ab, unlabeled
和
mount | grep /media/miki/05DB-E2AB
/dev/sdd on /media/miki/05DB-E2AB type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
这该如何解释？我如何知道可用空间？
