免安裝軟體讓-mac-也能讀寫-ntfs-格式

mount (chk /dev/disk2s1)
sudo umount /Volumes/HansNTFS
sudo mkdir  /Volumes/HansNTFS
sudo mount -o rw,auto,nobrowse -t ntfs /dev/disk2s1 /Volumes/HansNTFS

Disk編號

  • 可以由下列指令而得（如果mount df 或Finder都找不到）
$ diskutil list
ob-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
/dev/disk0 (internal):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                         28.0 GB    disk0
   1:                        EFI EFI                     314.6 MB   disk0s1
   2:                 Apple_APFS Container disk2         27.6 GB    disk0s2

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   1:                        EFI EFI                     209.7 MB   disk1s1
   2:                 Apple_APFS Container disk2         1000.0 GB  disk1s2
/dev/disk2 (synthesized):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

search device name

kuang@125-229-149-182 /Users/Seagate/data/NOAA/NCEP
$ diskutil list|grep Seagate
   2:       Microsoft Basic Data ⁨Seagate Expansion Drive⁩ 4.0 TB     disk3s2

mount device unto $vol_nam

  • /dev/disk3(type=GUID_partition_scheme)與/dev/disk3s2(type=Microsoft Basic Data)似乎是2個不同的區位
  • 前者無法寫入，後者則可。
vol_nam=/Volumes/Seagate\ Expansion\ Drive
sudo umount $vol_nam
sudo mkdir  $vol_nam
sudo mount -o rw,auto,nobrowse -t ntfs /dev/disk3s2 $vol_nam

restart seagate before fus.cs action

  • crontab as root
  • at 20:55 (before 21:00 sharp)
55 20 * * * ~/restart_seagate.cs >& ~/restart_seagate.out
  • content of restart_seagate.cs
#$ sudo cat /var/root/restart_seagate.cs
vol_nam=/Volumes/Seagate\ Expansion\ Drive
umount $vol_nam
mkdir -p  $vol_nam
mount -o rw,auto,nobrowse -t ntfs /dev/disk3s2 $vol_nam

results

$ mount|grep Seagate
/dev/disk3s2 on /Volumes/Seagate Expansion Drive (ntfs, local, noowners, nobrowse)

about Finder‘s control

  • 似乎不需（不能）由Finder來控制外接硬碟。
  • 當sudo umount $vol_nam之後，退出finder的連結，似乎在terminal運作外接硬碟才變得順暢。
  • Terminal 與 Finder 似為2種控制方式，互不相容。（Todo:待證實處理）
    • Terminal：umount之後，Finder就看不到了。
    • Finder拔插或斷電再開：Terminal看不到
