Verschlüsselt Bitlocker auch Daten einer formatierten Partition?
Wenn ich eine alte Festplatte mit Bitlocker verschlüssle und dabei “gesamtes Laufwerk verschlüsseln” auswähle, werden dann auch alte Daten einer bereits gelöschten/formatierten Partition mitverschlüsselt oder beiben die ungeschützt und können immernoch mit Recovery Software wiederhergestellt werden?
You’re right, Bitlocker encrypts everything with the selected option. Whether deleted file or not, the hard drive is encrypted at bit level. Depending on the size of the hard drive, it takes a long time
I noticed that too… Runs 10 hours on an 8TB drive and is only 60%.
When selecting “encrypt entire drive” only the new data that are written on the drive after encryption is encrypted. Existing data remains unencrypted and thus potentially recoverable. This means that even former data of a formatted partition that were not overwritten can be recovered with Recovery software.
To answer your question: No old/formatted data from a previous partition is included. Existing data remain unencrypted and must not be used to guarantee data security.
Okay, thanks for the info.
Are you sure you don’t mean “encrypt only used storage space” from the other function.
It is really that the whole hard drive is encrypted and not just the data currently on it. At least stands in the BitLocker dialog window…

Only the data currently on it is encrypted. So no data already deleted when you set up bitlocker.
However, if you have already deleted data, you need to overwrite the blank memory only once.
