What it is
Ariolic Disk Scanner is a free Windows utility for checking disks for read errors that may indicate drive degradation. It scans every sector on supported media in read-only mode, shows bad clusters as an image, and lists files located on unreadable sectors. The program supports all FAT variants and NTFS. It can scan internal and external disks visible in Windows, including USB sticks, Micro SD cards, CDs, and DVDs. No installation is required, so it can run from a flash drive or another disk. Ariolic says the checks do not alter data. The utility is intended as an early warning for drives showing failure signs, rather than a repair tool. Its knowledge base says scanning does not guarantee that an underlying issue will be fixed. The product page links to a free CNET download.
