# === SSD Installation & OS Clone ===
# Method 1: Clone existing HDD to SSD (Windows)
# Tools: Macrium Reflect Free, Clonezilla, Samsung Data Migration
# Using Clonezilla (Free, open source)
# 1. Download Clonezilla ISO
wget https://sourceforge.net/projects/clonezilla/files/clonezilla_live/3.1.2-9/clonezilla-live-3.1.2-9-amd64.iso
# 2. Create bootable USB
# Windows: Use Rufus
# Linux:
sudo dd if=clonezilla-live-3.1.2-9-amd64.iso of=/dev/sdX bs=4M status=progress
# 3. Boot from USB, select:
# - device-device (disk to disk clone)
# - Expert mode
# - Source: /dev/sda (old HDD)
# - Target: /dev/sdb (new SSD)
# - Enable: -k1 (resize partition to fit target)
# Method 2: Fresh Install (Recommended for 128GB)
# Windows:
# 1. Download Windows Media Creation Tool
# 2. Create bootable USB
# 3. Install Windows on SSD
# 4. Install drivers and software
# Method 3: Linux Fresh Install
# 1. Download ISO (Ubuntu, Fedora, etc.)
# 2. Create bootable USB
sudo dd if=ubuntu-24.04-desktop-amd64.iso of=/dev/sdX bs=4M status=progress
# 3. Boot and install
# Partition scheme for 128GB SSD:
# /boot/efi - 512MB (EFI System Partition)
# / - 50GB (Root filesystem)
# /home - 65GB (Home directory)
# swap - 4GB (Swap partition)
# 4. Post-install optimization for SSD
# Enable TRIM (usually auto-enabled)
sudo systemctl enable fstrim.timer
# Verify TRIM support
sudo fstrim -v /
# Check SSD alignment
sudo parted /dev/sda align-check opt 1
# Should say "1 aligned"
# Add noatime to fstab (reduce unnecessary writes)
# Before: /dev/sda2 / ext4 errors=remount-ro 0 1
# After: /dev/sda2 / ext4 noatime, errors=remount-ro 0 1

??????????????????????????????????????? 128GB ??????????????????????????????
# === Storage Optimization for 128GB SSD ===
# 1. Windows: Free Up Space
# Disk Cleanup
cleanmgr /d C
# Remove old Windows updates
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
# Move user folders to HDD (if available)
# Right-click Documents/Pictures/Videos ??? Properties ??? Location ??? Move
# Disable hibernation (saves ~4-8GB)
powercfg /h off
# Reduce page file
# System ??? Advanced ??? Performance ??? Virtual Memory ??? Custom size
# Clear temp files
del /q/f/s %TEMP%\*
del /q/f/s C:\Windows\Temp\*
# 2. Linux: Free Up Space
# Check disk usage
df -h
du -sh /* 2>/dev/null | sort -h
# Clean package cache
# Ubuntu/Debian
sudo apt clean
sudo apt autoremove -y
# Fedora
sudo dnf clean all
sudo dnf autoremove -y
# Clean journal logs (keep 7 days)
sudo journalctl --vacuum-time=7d
# Find large files
find / -type f -size +100M -exec ls -lh {} \; 2>/dev/null | sort -k5 -h
# 3. Move data to external storage
# Symbolic links for large directories
# Example: Move Steam games to HDD
# Windows:
# mklink /J "C:\Program Files (x86)\Steam\steamapps" "D:\Steam\steamapps"
# Linux:
# ln -s /mnt/hdd/steam ~/.steam
# 4. Enable Compression (Windows NTFS)
# Compress entire drive (saves 10-30%)
# Right-click C: ??? Properties ??? Compress to save disk space
# Or specific folders:
compact /c /s:"C:\Windows\WinSxS"
# 5. Monitor Space Usage Script
cat > check_space.sh << 'BASH'
#!/bin/bash
echo "=== Disk Usage Report ==="
echo ""
df -h / | tail -1 | awk '{print "Used: "$3" / "$2" ("$5" full)"}'
