questions:
* what's going on?
* how to find out?
* how to fix?
symptoms:
* can't write (gives read/write error).
* but files can get created and deleted.
* newly created files, which also have failed writes
have 0 bytes in them.
* mount /dev/sda1 /boot is slow.
* umount /boot is slow.
cave ~ # fsck.vfat -v -a -w /dev/sda1
fsck.fat 4.1 (2017-01-24)
Checking we can access the last sector of the filesystem
0x41: Dirty bit is set. Fs was not properly unmounted and some data may be
corrupt.
Automatically removing dirty bit.
Boot sector contents:
System ID "mkfs.fat"
Media byte 0xf8 (hard disk)
512 bytes per logical sector
4096 bytes per cluster
32 reserved sectors
First FAT starts at byte 16384 (sector 32)
2 FATs, 32 bit entries
565248 bytes per FAT (= 1104 sectors)
Root directory start at cluster 2 (arbitrary size)
Data area starts at byte 1146880 (sector 2240)
140520 data clusters (575569920 bytes)
63 sectors/track, 255 heads
2048 hidden sectors
1126400 sectors total
Got 4096 bytes instead of 562088 at 16384
