Saya memiliki kunci USB yang ingin saya format, tetapi saya tidak bisa:
- memformatnya di baris perintah:
Hasil:
mint@mint ~ $ sudo mkfs.ext2 /dev/sdb
mke2fs 1.42.9 (4-Feb-2014)
/dev/sdb is entire device, not just one partition!
Proceed anyway? (y,n) y
mkfs.ext2: Permission denied while trying to determine filesystem size
mint@mint ~ $ sudo mkfs.ext2 /dev/sdb1
mke2fs 1.42.9 (4-Feb-2014)
Could not stat /dev/sdb1 --- No such file or directory
The device apparently does not exist; did you specify it correctly?
- buat partisi:
Hasil:
mint@mint ~ $ sudo fdisk /dev/sdb
fdisk: unable to open /dev/sdb: No medium found
lihat di GParted atau di USB Stick Formatter
lihat partisi dengan
ls -l /dev/sd*
Hasil:
mint@mint ~ $ ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Jan 4 14:43 /dev/sda
brw-rw---- 1 root disk 8, 1 Jan 4 12:07 /dev/sda1

brw-rw---- 1 root disk 8, 5 Jan 4 11:22 /dev/sda5
brw-rw---- 1 root disk 8, 16 Jan 4 12:30 /dev/sdb
- baca dari itu

Namun saya melihat semua informasi yang tepat (Pabrikan, ...) tentangnya ...
Ada saran?
sudo
: No medium found
...
sudo dd if=/dev/sdb of=/tmp/xxx bs=512 count=1
(salin satu blok 512 byte ke / tmp / xxx). Pesan kesalahan apa pun di dmesg
atau syslog setelah itu? Tebakan terbaik saya sejauh ini: ada yang salah dengan tongkat Anda, ia disebutkan oleh USB, tetapi tidak bereaksi dengan benar ketika mencoba mengaksesnya.
/proc/partitions
?
no medium found
, Saya menambahkan output dari dmesg | tail
dalam OP
sudo
di kedua Andafdisk
perintah atau dimkfs
perintah
