O&O SafeErase - 24
SafeErase data from Solid State Drives (SSDs)
The frequent deletion and overwriting of files influences the life span of SSDs. It is not possible to run indefinite writing
access on the memory cell of a SSD. O&O SafeErase offers you a gentle method, to delete individual files, folders or
partitions from the SSD irrevocably. Files are deleted via a TRIM command. The data cannot be restored anymore.
O&O SafeErase recognizes SSDs automatically. The sequence and the control of the dialogs occurs analogously to
the deletion of normal hard disks so that you need not apply more settings.
Important: O&O SafeErase also leads you to the deletion method selection while deleting data from a SSD. Yet,
the deletion method will not be considered during deletion (trimming). If the data you selected is located on a hard
disk and a SSD, the selected deletion method will only be applied to the data on the hard disk.
Note: If your SSD does not support the TRIM command, please consider the warning notices given by the program.
Technical limitations for permanent deletion on Solid State Drives
SSD technology limits the possibility for permanent deletion in certain situations.
In the following cases, O&O SafeErase will permanently delete data using the „Overwrite with zeroes” deletion method
instead of TRIM commands:
l When deleting or moving very small files on NTFS drives. This usually affects files resident in the MFT.
l When deleting free space of cluster tips, MFTs, and FAT entries.
If partitions or entire drives on SSDs are deleted using TRIM, deletion will sometimes only be visible after the computer
is restarted. This depends on the SSD.
