Now and again when closing a program which has data stored on the ReadyNAS+ I see a "Delayed write failed to (a NAS based file)" warning pop up, and data is lost.
At home here we have 3 desktops+NAS & router in a wired network, which includes a WAP for 2 laptops. All PCs are running XPpro SP3 and updates, and the message is seen on all, on occasion. I'm the sole user of the desktops, (not all at once!)and network traffic is never more than from 1 PC and 1 Laptop. As far as I can tell, only one machine was attempting to access the NAS each time of the faults. The fault is intermittent, and does not happen every time data is written to the NAS or on every program closure. So far it has only happened on program closure.
It seemed kinder to set the NAS (4x500Gb recd. Seagate) drives to spin down for the more than 12 hrs a day the system's not in use, but this could result in an attempted access during spin down. Indeed, it's my suspicion that maybe some, but not all, software does not like finding the NAS drives spun down, and is not content to wait? Is this likely?
If not, what else should I look at?
PS. MS fixes appear to be aimed at local drives (set cache to OFF) or earlier versions of XP, (server writes....cured in SP2)
