There's more than a little irony that this freeware is designed to scan and test your hard drive for errors, but proved to be a problem itself.
Ariolic Disk Scanner starts off well with a basic user interface and straightforward command buttons. A drop-down list lets you choose which hard drive to scan. The program reads your hard-drive sectors and displays them as green and red blocks. We clicked on the large, green Start Scan button and, lo and behold, nothing happened. Testers reported the same results regardless of which drive was selected. Even a reinstall didn't fix the issue. The Help file was useless, as it gives only a brief description of what the app does. Or what it's supposed to do.
Our first impression of Ariolic Disk Scanner was a positive one, but it quickly changed after trying to test it. We suggest you save the space this program takes up and find another way to check your PC.
From Ariolic Software:
Disk Scanner is a freeware tiny utility to check the hard drive for read errors. Disk read errors may be the first typical sign of the possible disk failure. Ariolic Disk Scanner makes a raw sector read check of the hard drive and shows the result as a picture of your disk, where the good and bad clusters marked, so you can see the status of your disk at a glance and a list of files with read error.
What's new in this version:
Version 188.8.131.52 has improved disk scanning for errors.
- Raw read to test for if areas on a hard drive may be close to failing or about to fail.
- Obviously check for and detect areas already failed or failing (bad sectors).
- Very compact software with no bloatware and no install.
- No install needed which means run any time needed on any drive without leaving install files or junk in the registry for you to clean up (uninstall) later.
- Solid software company with a history of being solid. eg selling software to large manufacturers such as Seagate. (Unlikely to produce software with containing viruses/malware)
- Small graphical things could be fixed up like the map legend which shows what the green and red boxed mean being a bit obscured once the scanning process has started but nothing big.
- Software could have more features or info displaying the data or state of the hard drive but then I understand that why this software is free if you want more features that's how they sell their pay software.
To summarise this is a great, simple, free app! No problems downloading just click the link then run the cnet downloaded and it will download the Disk Scanner software. I can confirm that the cnet download app contains no virus and neither does the Disk Scanner 1.4 software when scanned with the latest virus update from Avast 9-Nov-2011. I found multiple sites offering this download advertising a range of virus software that had found no virus. I also found this page where it explains that a false positive was reported by Avast Virus Scanner late last year and then Avast fixed the problem with their Virus Scanner.
