Saved smartctl output can be opened as a read-only virtual device. The software supports ATA drives, including SATA and PATA, and NVMe drives, plus some devices behind USB bridges and selected RAID controllers. SCSI and SAS drives are not supported, though some information about them may appear. GSmartControl is free software under the GNU General Public License version 3. Downloads include Linux packages, Windows installers and portable archives, FreeBSD ports, macOS packages and source code. smartmontools is a runtime requirement, but official Windows packages include the required software.
