Media subtest selects the ReadOnly or WriteRead tests on USB storage devices, and compact flash and secure digital memory cards. By default all the read and write operations are completed using the asynchronous I/O method.
![]() | Caution - The Removable_Disk test recognizes file systems that only Oracle Solaris supports or recognizes. If the fstyp command on the Removable_disk reports the file system type as "Unknown", the Removable Disk test may write data to the partition if the safe testing is disabled |
If you enable unsafe testing, the test selects partitions automatically and runs WriteRead tests. The Unsafe option should be used with care. Unsafe testing can cause data corruption. The test will always run ReadOnly tests by default.
The partition will not be selected if it is mounted or has a file system.
For more information about Unsafe test options, see Safe and Unsafe Options.
