讀取外接3TB硬碟出現問題 - Linux

----最新更新 問題解決

換了外接盒cyberslim的，一切正常。

所以是外接盒的關係，現在1TB+3TB接在RPi一代上。


----

外接盒是玄人志向座式USB 2.0，硬碟 toshiba 3TB 格式NTFS

環境是arch linux @ raspberry pi 與 arch linux @ x86(筆電)


----

硬碟是在windows 7 底下格式化(GPT & NTFS)，拿到linux底下要使用時發現

沒有辨識出來，假設sda代表這顆硬碟，他並沒有顯示sda1這樣的分割區


[root@alarmpi rex]# ls /dev/sd*
/dev/sda


這時我利用fdisk查看了一下硬碟資訊，顯示如下


[root@alarmpi rex]# fdisk -l /dev/sda

The primary GPT table is corrupt, but the backup appears OK, so that will be
used.
Disk /dev/sda: 746.5 GiB, 801569726464 bytes, 1565565872 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 8B70A37D-25F0-44D1-979A-D52355A88B59

Device Start End Sectors Size Type
/dev/sda1 34 1565563919 1565563886 746.5G Microsoft basic data


顯示只有746.5G，上網搜尋一下fdisk好像不支援gpt的分割，但查詢應該沒有什麼問題？

於是安裝了gdisk來查詢試試，顯示如下


[root@alarmpi rex]# gdisk -l /dev/sda
GPT fdisk (gdisk) version 1.0.0

Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! One or more CRCs don't match. You should repair the disk!

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged

Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

請問這種情況會是外接盒支援度不足嗎？謝謝！
