I recently suffered a direct lightning strike to my house and it killed much of my Hi-Fi gear, including my beloved Sooloos system (TwinStore + Source:Five). I have the original TwinStore disks, which appear to be OK and a (slightly older) backup taken from the TwinStore.
The music files are readable in the [core ip address]\Share\music2\album folder.
This would be the case if the TwinStore was functional, but it got struck by lightening so is non functional. The only things that appears to be intact are the discs themselves, which due to the encapsulation of the underlying filesystem by the RAID, makes user recovery of data from the drives themselves without a TwinStore or MD600, a risky operation.
