1. Re: LR3 not writing metadata to xmp
Pete Marshall Aug 19, 2010 6:52 AM (in response to Bent Nielsen)From the message you have received and the statement made in the requirements for running LR on the Lightroom home page
minimum1GB of available hard-disk space
it would seem likely that 1 GB is the minimum. However I would suggest rather a great amount of free hard disk space is required in order for LR to function efficiently. But the minimum is pretty clear.Once you go below this you will experience problems and not just with writing metadata to file, but writing changes to the catalog itself if that is located on a disk with less than the minimum requirements The metadata once written takes up very little space, but the process of writing it can require space on disk for temporary files etc. Just make sure you have lots of spare capacity on any drive you use with LR.

2. Re: LR3 not writing metadata to xmp
clvrmnky Aug 19, 2010 6:49 AM (in response to Bent Nielsen)It probably doesn't have enough free space (somewhere) to make a full copy of the XMP file (I suspect changes are written to a copy and then renamed to the original in a safe three-way copy.)
200Mb is not enough free disk for any modern OS. I'd expect all sorts of problems.
However, that being said, at the time of the failure, the only information Lr has is regarding the specific IO operation that failed. So it is hard to know where you can free stuff up. Check the usual suspects, like temporary space (which depends on your platform.)
Free up some disk space and retry.

Bent Nielsen Aug 20, 2010 12:45 AM (in response to Bent Nielsen)@ Pete Marshall, clvmnky: thank you all. I have made 15GB space available on disk, so now there is a free flow of info.
