我已将 Seagate 外置硬盘 (FreeAgent 750GB) 连接到树莓派上的 Open Media Vault。一旦尝试进行任何写入操作，驱动器就会重新安装为只读。该机器是 raspberryPi v.1 B+ (r0OMV 4.1.13+)。不过，我可以将相同的驱动器连接到我的（manjaro 4.3.6-1-MANJARO）笔记本电脑上并写入数据，没有任何问题。
任何想法表示赞赏。鉴于这是一个在其他系统上工作正常的磁盘，我不想简单地购买新磁盘，因为它可能与 raspberryPi 和 OMV 存在相同的问题。我可以重复我已经完成的以下步骤，并且再次得到完全相同的结果。只是说 - 该磁盘在同一台树莓派机器上运行一周左右，并且仍然可以在我的笔记本电脑上运行良好。该磁盘已使用 7 年。到目前为止我的故障排除步骤是：
1）卸载并执行fsck：
root@r0OMV:~# e2fsck /dev/sda1
e2fsck 1.42.5 (29-Jul-2012)
ForteBKP: recovering journal
ForteBKP contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
ForteBKP: 11/45793280 files (0.0% non-contiguous), 2924481/183143385 blocks
我可以安装它后立即：
mount -a
然后挂载显示：
/dev/sda1 on /media/49fb4a0f-c826-4a7c-877a-76c98dba5b2c type ext4 (rw,noexec,relatime,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group,_netdev)
如果我尝试 mkdir 我会收到错误：
mkdir: cannot create directory `/media/49fb4a0f-c826-4a7c-877a-76c98dba5b2c/touch': Read-only file system
并安装显示：
/dev/sda1 on /media/49fb4a0f-c826-4a7c-877a-76c98dba5b2c type ext4 (ro,noexec,relatime,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group,_netdev)
当发生这种情况时，系统日志输出是：
Mar 5 12:08:48 r0OMV kernel: [49725.089841] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: user_xattr,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl

2) 采取的其他措施： 我调查过高清参数和智能控制
root@r0OMV:~# hdparm -I /dev/sda1
/dev/sda1:
ATA device, with non-removable media
Model Number: ST3750640AS
Serial Number: 5QD40Q51
Firmware Revision: 3.AFM
Standards:
Supported: 7 6 5 4
Likely used: 7
Configuration:
Logical max current
cylinders 16383 16383
heads 16 16
sectors/track 63 63
... the rest of output seems normal and I cut it for the sake of brevity
root@r0OMV:~# hdparm -r0 /dev/sda1
/dev/sda1:
setting readonly to 0 (off)
readonly = 0 (off)
root@r0OMV:~# hdparm -W /dev/sda1
/dev/sda1:
write-caching = 0 (off)
但这并没有产生任何结果。
和智能控制经过长时间的测试我发现结果是
smartctl -H /dev/sda
smartctl 5.41 2011-06-09 r3365 [armv6l-linux-4.1.13+] (local build)

答案1
我有一个 USB 适配器也有类似的行为。听起来很奇怪，安装 ext3 是因为 ext2（意味着不记录日志）允许磁盘工作。也许这是一个选择。
