Dvars vhl series has a problem that when power fails, then it most probably will loose materials saying hdd needs to be formatted to continue.
If materials are critical then the workaround exists. We need:
- Same size drive or any other storage that has enough space for materials
- Pc with windows and CMS from dvars vhl cd installed
- Any linux livecd (ex: partedmagic)
It is suggested to use Linux live cd instead of ext2fs windows driver due to some bugs in windows driver(blue screen is OK behavior of) and no needed functionality(fsck). Put drive to pc and start livecd. Initiate fscheck (fsck -yf /dev/DeviceName). When complete, copy IMAGE dir into empty drive. After that in windows CMS should be started, archive player selected. Materials are ready to playback, however not really convenient to browse these materials.
