Disk SpeedUp vs DiskTuna

Disk SpeedUp is a Windows utility for analyzing and defragmenting drives, as well as optimizing individual files and folders. Its interactive drive map displays fragmentation results. Defragmentation modes can optimize placement for less frequently accessed files or prioritize frequently used ones. Scheduling lets users choose an action, frequency, time, and drives. It can also defragment system files at boot, including page files, registry hives, and hiberfil.sys. The utility offers SSD optimization settings, but its knowledge base says defragmenting SSDs is not recommended because it may reduce their lifespan. Supported file systems are FAT 16/32 and NTFS. Users can exclude files and folders, enable Disk Defrag in the Windows Explorer context menu through Glary Utilities settings, and set the computer to shut down after defragmentation. Glarysoft says the product is designed to avoid damage to drives or stored data and typically responds to technical questions and bug reports within one or two business days. It is listed as freeware at free, with no free trial. The download page lists version 6.0.1.17.

DiskTuna’s JPEG-Repair Toolkit combines JPEG-Repair for damaged photos with JpegDigger for recovering lost images. It runs on Windows 7, 8, 10, and 11 and processes files locally on the PC, without uploading them to remote servers. JPEG-Repair addresses corrupt headers, invalid markers, bad-sector damage, and JPEG bitstream errors with visual feedback. It can recover JPEG data from corrupt RAW photos such as Canon CR2 and Nikon NEF files, and does not re-encode JPEG images. The demo shows low-resolution previews; the full version enables high-quality saves. Repairing a corrupt JPEG header requires a reference photo made with the same camera and settings. The toolkit specializes in JPEG and specified RAW formats and does not repair PNG files. The listed plan includes both tools and is billed at €29.00–€49.00, excluding applicable taxes. Downloads are unsigned and may trigger Windows SmartScreen warnings, including after updates. The maker offers a refund only when the demo works on the files but the full version fails on those same files.
