Hi omnes. In vigilia initium novum cursum coetus Materiam utilem a nostro discipulo scriptam praedicamus, necnon matronae cursum, auxilium technicum specialitas pro products corporatum REG.RU - Roman Travin.
Hic articulus considerabit 2 casus reponendi orbis ac informationes transferendi ad novos orbes capacitatis amplioris cum ulteriore expansione systematis ordinati ac lima. Primus casus ad subrogationem orbis cum eisdem MBR/MBR vel GPT/GPT partiendis spectabit, secundus casus ad subrogationem orbis cum MBR partitionibus cum disci cum capacitate plus quam 2 TB, in quo instituere debebis. GPT partitio cum biosboot partitio. In utroque casu, orbis ad quos notitias transferimus, iam in calculonis servi sunt. Tabellae ratio adhibita ad partitionem radicis ext4.
Causa I: Repositoque minor orbis cum maior orbis (usque ad 1TB)
Negotium: Reponere orbis vena cum maioribus orbis (usque ad 2 TB) cum notitia translationis. In hoc casu habemus 2 x 240 GB SSD (RAID-1) orbes cum systemate inaugurato et 2 x 1 TB SATA orbis ad quos ratio transferri debet.
Inspice orbis hodiernam extensionem.

Exercitatio: Praesens repone cum orbis maioribus orbis (2 x 3TB) servatis informationibus. In hoc casu habemus 2 x 240 GB SSD (RAID-1) orbes cum systemate inaugurato et 2 x 3 TB SATA orbis ad quos ratio transferri debet. Discus currentis in mensa partitione MBR utuntur. Cum in novis orbis capacitatem maiorem quam 2 TB habeant, necesse erit ut tabula GPT utatur, cum MBR non possit cum orbiculis amplioribus quam 2 TB laborare.
Inspice orbis hodiernam extensionem.
