我的 SD 卡有一些问题，但我无法修复它们。
这是磁盘在 GNOME 磁盘中的样子：
当我运行时gdisk /dev/sdb，它给出以下输出：
sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 1.0.3
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
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: hybrid
BSD: not present
APM: not present
GPT: damaged
Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.
我不确定应该使用哪个分区表，但我使用了 GPT（创建空白 GPT 没有帮助）分区如下所示：
Command (? for help): p
Disk /dev/sdb: 125067264 sectors, 59.6 GiB
Model: Multi-Card
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 76A0F070-E171-475B-9409-53840D61AD12
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 4194270
Partitions will be aligned on 2048-sector boundaries
Total free space is 671677 sectors (328.0 MiB)
Number Start (sector) End (sector) Size Code Name
1 2048 67583 32.0 MiB 0C01 hassos-boot
2 67584 116735 24.0 MiB 8300 hassos-kernel0
3 116736 641023 256.0 MiB 8300 hassos-system0
4 641024 690175 24.0 MiB 8300 hassos-kernel1
5 690176 1214463 256.0 MiB 8300 hassos-system1
6 1214464 1230847 8.0 MiB 8300 hassos-bootstate
7 1230848 1427455 96.0 MiB 8300 hassos-overlay
8 1427456 3524607 1024.0 MiB 8300 hassos-data
当我想验证磁盘时，我会得到这个信息：
Caution: The CRC for the backup partition table is invalid. This table may
be corrupt. This program will automatically create a new backup partition
table when you save your partitions.
Problem: The secondary header's self-pointer indicates that it does not reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.
Identified 2 problems!
我可以设法解决这些问题，然后我得到了这个按摩：
No problems found. 121544637 free sectors (58.0 GiB) available in 2
segments, the largest of which is 121542623 (58.0 GiB) in size.
但在写完之后我得到了这个：
OK: writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.
但是当我再次检查分区时，它仍然是一样的。我试图一个一个地删除所有分区，然后创建一个新的空 GUID 分区表，但写完后我得到了这个：
OK: writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.
但是当我再次检查分区时，它仍然是一样的。我认为这是因为混合 MBR 和损坏的 GPT。有没有办法同时删除这两个表？或者我还能做些什么来解决这个问题？
