HearthCardCheck is described as 'A counterfeit memory card is a small, genuine card whose controller chip has been programmed to report a much bigger size. Anything written past its real capacity either wraps back over earlier data or simply vanishes, which is why photos and videos silently corrupt weeks after' and is a hard disk diagnostic tool in the os & utilities category. There are more than 10 alternatives to HearthCardCheck for Windows, Linux and Mac. The best HearthCardCheck alternative is HD Tune, which is free. Other great apps like HearthCardCheck are H2testw, F3, ValiDrive and Macrorit Disk Scanner.
HD Tune is a hard disk / SSD utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and more!.
Data integrity test for USB sticks and other media
An advantage over other tools is, that it does not need administrative rights to access the device - but it should not be NTFS formatted, as it does not allow to test everything.
You can FAT32 format hard drive partitions large.
F3 is an open source command-line tool that assesses the real capacity of USB sticks and other media. An advantage over other tools is, that it does not need administrative rights to access the device.
Quickly spot-check any USB mass storage drive for fraudulent deliberately missing storage.
Macrorit Disk Scanner is a third party disk surface portable tool for scan disk bad sectors which provides you with better options and better performance than Windows native disk scanner.
Tool to test a USB drive or memory card to find out if it's a fake. The tool performs a simple test to determine if the full capacity is usable or not. All it does is fill the volume with test data and verify if the data on the volume is correct.
Quick Disk Test fills a disk with test data and verifies that it can be read back without errors.
Reads disk files or directories and stops on the first read error.
There are two versions: a command-line perl script and a Java GUI.
MediaTester can test any media (SD, microSD, USB thumbdrive, etc) and verify it stores the expected number of bytes. The testing method is similar to h2testw but MediaTester can detect fake or defective media much faster by performing quick reads as data is written.
Flash card/drive tester allows testing of any removable media including SD, MMC, CF, USB flash pen drives for bad or unstable sectors. Especially useful for testing for fake sizes often seen on low quality USB pen drives.
Tests USB Flash drives and Flash memory SD cards to determine if they are fake (not full capacity). Much quicker than H2testw.
