Suresh -
When configured properly RT systems are very stable deterministic systems, but on rare occasions a crash can still occur. In most situations recovering data may be as simple as FTP'ing to the RT system and downloading the data files. However, if a crash occurs while a file is being written it can corrupt the file, the sector on the disk, and possibly even the drive (similar to the behavior in any OS).
If the PXI chassis is booted into windows, any disk recovery tools that runs in windows may be used to attempt recover corrupt files or sectors.
Partitioning a drive when using Windows works great, but is not supported in RT. At this time RT will only recognize the first partition on each physical drive.
