Hi,
that all is MOST interesting. I'm fighting data losses since quite some time, under WinXP SP2 + all updates, since last year. Losses were intermittently, just a few in the beginning, most on my 2nd (data) drive, first 80GB partition (E) of a 160 GB one. But meanwhile I had losses on other partitions too. Unfortunately I ran chkdsk (Windows insisted on doing it) and lost several full folders and other data that way.
I've been talking to a lot of people, no good answers. The latest anyway was to check for high temp problems. This made me acquire HDD cooler fans (dual) for each of my new replaced drives, and I run HDTemp to get a notification when over 50 °C. Which I don't expect with the coolers.
But then I read the MS page about 48bit LBA support
http://support.microsoft.com/kb/303013/EN-US/ and also the one mentioning possible data corruption when recovering from hibernation or standby etc.
http://support.microsoft.com/kb/331958/EN-US/ .
I was aghast, but honestly couldn't fully get to grips with the explanations & advice they gave on these pages. Since I have SP2, there shouldn't be problems with the 48bit LBA thing I thought?
My mind still isn't at rest with all this, and I'm honestly expecting more corruptions to come ... [btw, where did I store away my UBuntu CD ... ?]
Seagate btw has some explanations too re. 48bit LBA etc.:

Additionally also MS re. data losses after standby or hibernation
