Ariolic Disk Scanner

What Ariolic Disk Scanner is

Ariolic Disk Scanner is a free Windows utility that checks disks for read errors that may indicate drive degradation. It scans every sector on supported media in read-only mode, displays bad clusters in an image, and lists files found on unreadable sectors. The utility supports all flavors of FAT and NTFS, and can scan internal or external disks visible in Windows, including USB sticks, Micro SD cards, CDs, and DVDs. It requires no installation and can run from a flash drive or another disk. Ariolic describes its checks as read-only and says they do not harm data. The utility is intended to provide an early warning when a drive shows signs of failure; scanning does not guarantee that the underlying issue will be fixed. It is freeware, and the product page links to a free download hosted on CNET.

Who it suits

Disk Scanner suits Windows users who want to check supported disks for read errors, including users seeing signs of drive failure. Its portable, no-install design may suit people who want to run it from removable storage.

Limits

The free plan scans for read errors, but does not provide read/write testing. A scan can offer an early warning and does not guarantee that an underlying issue will be fixed.

Getting started

1. Visit the Ariolic Disk Scanner product page.
2. Use the page's link to the free download hosted on CNET.
3. Run the utility from a flash drive or another disk; installation is not required.
4. Scan a supported disk visible in Windows.

Verdict

Ariolic Disk Scanner can identify read errors and files on unreadable sectors without writing to the scanned media. Treat it as an early warning tool, not a guarantee of repair.
