In 2008, Hard Disk Sentinel DOS version was released in different formats on bootable pen drive, CD, floppy.

The data on a RAID 1 volume is the same as on a normal partition. The RAID information is stored in the last 128kB of the partition. This means, to convert a RAID 1 volume to normal data partition, it is possible to decrease the partition size by 128kB and change the partition ID from fd to 83 (for Linux).
In 2010, hard-disk manufacturers introduced drives with 4,096‑byte sectors (Advanced Format). [3] For compatibility with legacy hardware and software, those drives include an emulation technology ( 512e ) that presents 512‑byte sectors to the entity accessing the hard drive, despite their underlying 4,096‑byte physical sectors.

The table below identifies each notable operating system and the first version supporting the command. Additionally, older solid-state drives designed before the addition of the TRIM command to the ATA standard will need firmware updates, otherwise the new command will be ignored. However, not every drive can be upgraded to support trimming.
