Problem: "Access denied" or "Cannot write to drive." Solution: Close File Explorer. Some processes lock the drive. Also, ensure the drive is not write-protected (physical switch on SD cards/USB sticks).
Problem: Test stops at 4GB on a FAT32 drive. Solution: Mydisktest V2.42 can exceed the 4GB file limit on FAT32 by splitting the test? Actually, no—FAT32 cannot hold a single file >4GB. Workaround: Reformat the drive to NTFS or exFAT before testing. Mydisktest V2.42
Problem: The program freezes at 99%. Solution: This often happens with dying hard drives that go into read-retry loops. Let it run for up to 2 hours, but if no progress, the drive is failing physically. Abort and recover data immediately. Problem: "Access denied" or "Cannot write to drive
Problem: I want to test only a portion of the drive. Solution: Mydisktest V2.42 does not have a range selector. However, you can fill the drive with a large file, delete it, then run the "Read test" on the empty space. Why has version 2
Why has version 2.42 persisted for over a decade? Because its core features are precisely what technicians need without bloatware, ads, or installation requirements.
If you’ve ever lost data to a fake USB drive or a dying SD card, you know the pain. In the endless sea of storage utilities, Mydisktest V2.42 remains a quiet but powerful contender. Recently, I gave this version a thorough spin. Here’s what I found.
Version 2.42 represents one of the stable iterations of the software before development largely stalled.
