Seeing what is on the machine
The Disks utility (or KDE Partition Manager) shows drives, sizes, and filesystems. df -h in a terminal summarizes free space. When the root filesystem hits 100%, Linux can refuse to log in normally - same class of emergency as a full Windows C: drive. Leave headroom.
USB drives
Plug in, wait for the notification, browse files, eject before unplug. If a Windows disk was not fully shut down (Fast Startup/hibernation), it may mount read-only. That is Linux protecting you from corrupting a hibernated filesystem - shut down Windows cleanly or disable Fast Startup.
Format USB sticks only when you mean to erase them. FAT32/exFAT for cross-platform sticks; avoid exotic filesystems if the stick must also work on a school Windows PC.
Adding a second drive
Extra SSDs for photos are great. Mount them with the disks UI to a folder in your home or /mnt, test, then if needed enable mount-at-startup with guidance. Wrong automatic mounts can stall boot - another reason to make one change at a time and keep a live USB handy.
Failing disks
Clicking, SMART reallocated sectors, multi-second freezes when opening folders - stop writing, copy critical data off if possible, and get hardware help. Installing more software will not heal NAND that is done. Our data recovery stance is honest: assessment first, no guarantees - see policies.
When to stop DIY
When the stack exceeds DIY - drive failures, dual-boot disasters, locked accounts, or a machine that must be online for work tomorrow - contact CCPCREPAIR in Tahlequah. We do diagnostics with a flat quote after we know what is wrong. Call 918-228-5889 or use the form.

At CCPCREPAIR in Tahlequah we see the same pattern repeatedly: people succeed with Linux when they slow down for backups, pick a mainstream distro, and treat the first week as landing the plane - updates, browser, printer - before theming and experimental drivers. They fail when they skip the backup, click through erase-disk options, or paste sudo commands they cannot explain.
Keep a live USB of the same distro in a drawer. It is a recovery tool as much as an installer. When something will not boot, the live session is how you copy files off and read logs without making the problem worse. That habit alone separates calm operators from emergency tickets.
If you share a machine with family, write a one-page note: distro name, username model (not the password), whether the disk is encrypted, and where the backups live. Future you - or a technician - will move faster with that sheet than with a vague memory of a YouTube video from three months ago.
Continue the series in order when you can, but jump ahead if you already know the topic. Every page ends with abort criteria and a path to contact the shop when risk climbs. Linux is easy when honesty about hardware and data comes first.
