System: XP SP3 Pro + Ext2Fsd 0.51, Windows profile on Ext2 volume
In Event Viewer there are identical warnings approx. every other day reading:
Event ID: 50
Event Type: Warning
Event Source: Ext2Fsd
Description: Windows - Delayed Write Failed : Windows was unable to save all the data for the file "". The data has been lost. This error may be caused by a failure of your computer hardware or network connection.
Please try to save this file elsewhere.
Note: It is exactly like this, with empty file name!
When this happens, I have a popup in the system notification tray with the same message ("Delayed write failed ... data has been lost ... elsewhere.") but here there is a filename, and in all cases I recognized this was a temporary Sqlite file in the Skype profile ( \Device\HarddiskVolume5\...\Skype\<my user profile>\etilqs_<20 random chars>).
I should add: S.M.A.R.T. of this hard disk shows it is healthy and there are no file system errors when this partition is mounted on Linux. It seems that the Ext2Fsd driver sometimes fails on delayed writes.
