Thanks for getting in touch. If those drives were originally in a RAID set managed by your PC’s motherboard or a dedicated RAID controller, your new QNAP TS-464 will not automatically recognize that array. QNAP’s RAID system (mdadm under the hood) is specific to its own setup and can’t import arrays created by Windows, Intel RST, or most hardware RAID cards.
The safest approach is not to insert the old drives directly into the new NAS yet. Instead, connect them to a computer using SATA or a USB dock and check whether they mount individually. If they were in RAID 1, each drive may still contain readable data and can often be accessed directly. If they were in RAID 0, the data is striped across both drives and will only be recoverable using software tools that can rebuild the RAID metadata manually (like R-Studio or ReclaiMe).
