A flaw in Microsoft (NSDQ: MSFT)'s Windows Home Server could lead to data loss under certain circumstances, the company has confirmed.
Windows Home Server, released over the summer, aims to offer home users centralized media storage and home backup capabilities for networked PCs.
Microsoft last week updated a support document acknowledging that files edited using certain programs and then stored on Windows Home Server could become corrupted.
"Microsoft is researching this problem and will post more information in this article when the information becomes available," the Microsoft help documentation explains. "Until an update for Windows Home Server is available, we recommend that you do not use the programs that are listed in this article to save or to edit program-specific files that are stored on a Windows Home Server-based system."
The listed programs are as follows: Windows Vista Photo Gallery, Windows Live Photo Gallery, Microsoft Office OneNote 2007, Microsoft Office OneNote 2003, Microsoft Office Outlook 2007, Microsoft Money 2007, and SyncToy 2.0 Beta.
The issue was acknowledged in October, when Microsoft warned "not to copy data files that contain alternate [NTFS] data streams to Windows Home Server shared folders." Microsoft offers free software called Streams to determine whether NTFS files have alternate data streams associated with them.
Microsoft also says that some users have reported problems with Torrent applications, Intuit Quicken, and QuickBooks program files and that it is attempting to reproduce those issues.
Microsoft says that file corruption can occur under circumstances when a home server is under extreme loads, as might happen when copying large numbers of files, when a user is editing files already saved to a shared folder on the home server, and when a user is using one of the listed programs to edit files on a home server.
That was posted with NetBSD, BTW, which shows that I’m not a “professional.” ;-)
How are things in the mountains?
Samba’s good. I like using Xen (free, fast hardware virtualization thingie) and VNC viewers...makes one legitimate, Windows Cheap Edition system go a long way. ;-)
You also have a private message. Let us know how things are going for you. We only get down that way once in a great while.
Samba rocks. I use it all over the place on my work and home networks.
What I can't understand is, Windows Home Server is a dumbed-down version of Server 2003, which does not have these problems. I have 2003 servers all over at work and they run fine.
So what's up Microsoft? How did you break it? This is not "innovation"... this is the stupidest "step on your own d!ck" product I've seen from MS in years!
Well, maybe Vista...
“A flaw in Microsoft ...”
Does anyone have to read further?
If we didn’t have the limp boys from Microsoft maybe we would have an OS that worked. Might save us billions in productivity.
Didn't they do beta testing?
Screw that, did it not occure to them that consumers might want to edit files on a server and use it like a server? If the goal was a NAS, we can buy them for much less. Heck, I can add a hard drive to my router.

Massive Data Loss Bug in Leopard
November 5th, 2007
Update: The bug occurs regardless of the type of destination being moved to (whether its local USB, local Firewire, SMB, etc.). Also, I have been informed that this bug goes back all the way to Panther.
Update 2: Heres a video of the same thing happening to a USB drive: http://tomkarpik.com/pub/leopardmovebug.avi
Update 3: Robert Rodgers adds: I accidently chmodd a directory while a massive (40+GB) file move was being copied into it to be -w by me, files went poof.
Leopards Finder has a glaring bug in its directory-moving code, leading to horrendous data loss if a destination volume disappears while a move operation is in action. I first came across it when Samba crashed while I was moving a directory from my desktop over to a Samba mount on my FreeBSD server.
Ive now run tests on a Windows XP SP2 SMB mount, as well as a local HFS+ formatted USB drive, and the bug surfaces every time the destination disappears while the Finder is moving something to the destination.
