Alrighty, here are the results, and they look as expected. |

The harddrive in question is in fact FAT-formatted and is mounted thus: |
| 21 |
/dev/sdc1 on <path> type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) |
| 22 |
|
| 23 |
While an NTFS-formatted drive of mine gets this: |
| 24 |
/dev/sdb1 on <path> type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096,uhelper=udisks2) |
| 25 |
|
| 26 |
Notice that only the FAT disk is mounted with the flush option, hence my |
| 27 |
inability to reproduce the other day. I remounted the drive with the exact |
| 28 |
same options as it got from the automounter, but without the flush option. |
| 29 |
The delays were gone. |
| 30 |
|
| 31 |
So I will either have to find a way to give the KDE mounter some options |
| 32 |
(preferably only for HDDs, but not USB thumbdrives), or live with the |
| 33 |
observed behaviour. It’s not like I’m using FAT-formatted disks myself any |
| 34 |
longer (except for USB sticks and SD cards). |
| 35 |
|
| 36 |
So long. |
