Đây là drop hay sync?
You should never have to sync manually under normal circumstances if your system is working properly. (Even though I do sometimes after unmounting a usb key or a memory card but that's technical superstition moer than anything else.) Any call to halt or chutdown or hibernate will sync as part of their work.
I am speechless if you don't mention the version of your kernel. Basically, the sync(2) command executes the system call sync() BR, Nguyen Vu Hung
