Introduction

Storage media management is a fundamental aspect of working with Linux systems. Whether you’re a new Linux user or looking to expand your knowledge, understanding how to work with different storage devices is essential. This guide will walk you through the basics of storage media management in Linux, from mounting devices to creating file systems.

Types of Storage Media in Linux

Essential Storage Commands

# Mount a USB drive
sudo mount /dev/sdb1 /mnt/usb

# Unmount a device
sudo umount /dev/sdb1

# Check file system integrity
sudo fsck /dev/sdb1

# Force check on next reboot
sudo touch /forcefsck

# Start fdisk for a device
sudo fdisk /dev/sdb

# Common commands:
# p - print partition table
# n - create new partition
# d - delete partition
# w - write changes

# Create ext4 filesystem
sudo mkfs -t ext4 /dev/sdb1

# Create FAT32 filesystem
sudo mkfs -t vfat /dev/sdb1

Working with Different Storage Types

# Mount CD/DVD
sudo mount /dev/cdrom /mnt/cdrom

# Create ISO image
dd if=/dev/cdrom of=backup.iso

# Mount NFS share
sudo mount -t nfs server:/share /mnt/nfs

# Mount Samba share
sudo mount -t cifs //server/share /mnt/samba

Your Turn! Practical Exercise

Problem: Create a new partition and format it with ext4.

Steps:

1. Identify your device using lsblk
2. Create partition with fdisk
3. Format with ext4
4. Mount and verify

sudo fdisk /dev/sdb
# Use n for new partition
sudo mkfs.ext4 /dev/sdb1
sudo mount /dev/sdb1 /mnt/data
df -h /mnt/data

Quick Takeaways

• Always unmount devices before physical removal
• Regularly check file system integrity
• Back up important data
• Use appropriate file systems for your needs
• Document your storage configuration

FAQs

1. Q: How do I safely remove a USB drive? A: Always use umount before physical removal to prevent data corruption.

2. Q: Why can’t I mount my drive? A: Check permissions, ensure the mount point exists, and verify the file system type.

3. Q: How do I check disk space? A: Use df -h for mounted file systems and du -h for directory usage.

4. Q: Can Linux read NTFS drives? A: Yes, with the ntfs-3g driver installed.

5. Q: How do I repair a corrupted file system? A: Use fsck in recovery mode or from a live USB.

Best Practices

1. Regular Maintenance
   • Check file systems periodically
   • Monitor disk health
   • Keep backups current
2. Safety Measures
   • Always unmount before removing devices
   • Use write protection when needed
   • Verify checksums for important data
3. Performance Tips
   • Choose appropriate file systems
   • Regular defragmentation (when needed)
   • Monitor disk space usage
