我正在尝试修复格雷德迷你1TB外置硬盘上的GPT损坏分区表.以下是gdisk的报告：
root@philippe-desktop:/home/philippe/thomasdisk# gdisk /dev/sdb GPT fdisk (gdisk) version 0.8.8 Caution: invalid main GPT header,but valid backup; regenerating main header from backup! 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. **************************************************************************** Command (? for help): ? b back up GPT data to a file c change a partition's name d delete a partition i show detailed information on a partition l list kNown partition types n add a new partition o create a new empty GUID partition table (GPT) p print the partition table q quit without saving changes r recovery and transformation options (experts only) s sort partitions t change a partition's type code v verify disk w write table to disk and exit x extra functionality (experts only) ? print this menu Command (? for help): v No problems found. 262157 free sectors (128.0 MiB) available in 2 segments,the largest of which is 262151 (128.0 MiB) in size.

我的理解是,gdisk可以自动解决损坏,只需按w就可以修复我的磁盘,但我不确定通常v(验证)选项应该向我提出revovery选项.
我可以安全地去按w吗？我已经做过sgdisk -b backup.gpt / dev / sdb
