Hi
I've got an LS-CHL 1TB on firmware version 1.06.
I got a lot of music on my PC that I want to keep in sync on the LS. I intend to use Robocopy in mirror mode for this so that I don't copy unchanged files. I've used this technique elsewhere with no problems so I'm comfortable with it.
I did this the first time with my music and everything copied OK but when I ran it a second time (with nothing changed so no copies should have taken place) I found that every file copied again.
When I checked the file times on the LS I found them to be slightly different to the ones in Windows hence why Robocopy thought the files on the Windows system were newer and copied them all again.
e.g. a file created on 6 Nov has a created time on Windows of 15:00:29 and 15:15:26 on LS
modified time is 15:18:25 on Windows and 15:18:24 on LS
accessed time is 15:15:27 on Windows and 15:15:26 on LS
The created and accessed times on the LS always seem to be the same and the accessed/modified times on the LS always seem to be a second or two behind Windows.
Has anyone else come across this problem and is there a solution?
I can see there's a FW 1.07 available but it doesn't say anything about this problem.
I've also seen there is 1.21 available only for v2 hardware. I presume mine is v1 but how can I tell?
Thanks.

At least two problems here:
1) The Buffalo NAS boxes use Samba to present its file system as NTFS (as far as possible) to Windows. However the "timestamp granularity" of Samba is the same as FAT, namely 2 seconds. The time of files copied from NTFS to NAS are rounded up where necessary to a 2-second boundary. For ROBOCOPY read about (and use) the /FFT switch.
2) The only meaningful NTFS time is the File Modified Time; File Created Time can be entirely wrong, and File Access Time is (quite literally) a waste of disk space. Read this Windows File Date and Time (//%3Ca%20rel=%22nofollow%22%20target=%22_blank%22%20href=%22http://www.xxcopy.com/xxcopy15.htm%22%3Ehttp://www.xxcopy.com/xxcopy15.htm%3C/a%3E) article, especially from the middle downwards.
You have a version 1. And I would try updating to 1.07.
Thanks, your information was really helpful and fixed my problem :-)
As an aside has anybody got an easy(ish) way to get Squeeze Centre running on v1?
I once saw something for v2 but it warned against trying it on v1.
Thanks again.
Anybody got any clues about Squeeze Centre running on v1?
Thanks.
