Preparation (installing needed utilities etc.) The section topics and numbers are mostly the same for both guides. It only covers the most general use cases with SailfishOS 2.2.0 and newer.įor details, variations, technical background and SailfishOS versions before 2.2.0, please consult the original how-to. This is an enhanced, updated and streamlined guide created from the original " Creating partitions on SD-card, optionally encrypted". Alter an encrypted partition on SD-card created per Settings -> Storage -> Format: Encrypt (which has to be manually mounted) to be automatically mounted (when booting the device), while retaining the data on itĪs Jolla introduced its SD-card encryption with SailfishOS 3.0.0 (i.e., after this guide was written), this is provided as a short addendum (section 9), which references the few relevant sections.Create a small vFAT32 partition (e.g., slightly below 8 GB, see section 3.2.b) and split the remaining space on SD-card between an unencrypted and an encrypted partition.

Split the space on SD-card between an unencrypted and an encrypted partition.

Create a small vFAT32 partition (e.g., slightly below 8 GB, as described in section 3.2.b) and a large second, encrypted partition.

Typical use cases / partitioning schemes are:

Repartitioning an SD-card, deploying multiple filesystems (unencrypted and / or encrypted)Īs this is what this guide was developed for, there is no shortcut one can take (except for the obvious omission of section 3.2.a).Reformatting an SD-card to a Linux-native filesystem (unencrypted or encrypted)Įither perform this in the SailfishOS' settings app for unencrypted partitions or (if this fails, if you want more control or if you want to deploy an encrypted partition, avoiding the drawbacks of partitions encrypted with SailfishOS' 3.x.y own mechanism: no automatic mounting at boot time, no android_storage possible on encrypted SD-card etc.) walk through sections 1, 2.1, (you can omit 2.2.x), 3.1, 3.2.a, 4.2 (unencrypted) or 4.3 (encrypted) and finally 5.Reformatting a SDXC-card (pre-formatted with exFAT) to vFAT32Įither perform this in the SailfishOS' settings app or (if this fails or if you want more control) walk through sections 1, 2.1, (omit 2.2.a), 2.2.b, 2.3, 3.1, 3.2.a (just set partition type to "c") and 4.1.
