# Drive Selection Reference
|
|
|
|
Based on your system screenshots, here's the correct drive mapping:
|
|
|
|
## Current System Layout (from screenshots):
|
|
|
|
### Available Drives:
|
|
- **`/dev/nvme0n1`** - 476.9G KXG6AZNV512G TOSHIBA
|
|
- ✅ **INTERNAL DRIVE** (source)
|
|
- This is your current system with:
|
|
- nvme0n1p1: 58GB Linux filesystem (root)
|
|
- nvme0n1p2: 512MB EFI system
|
|
- nvme0n1p3: 417GB Linux filesystem (home)
|
|
|
|
- **`/dev/sda`** - 476.9G Tech JMicron
|
|
- ✅ **EXTERNAL M.2 SSD** (target)
|
|
- This should be selected as migration TARGET
|
|
- Will be completely wiped and converted to LVM
|
|
|
|
- **`/dev/sdb`** - 119.3G Extreme Pro SanDisk
|
|
- 🔧 **USB STICK** (migration tools)
|
|
- This USB stick with the migration tools
|
|
- Should NOT be selected for migration
|
|
|
|
## Correct Migration Configuration:
|
|
|
|
```
|
|
Source (Internal): /dev/nvme0n1 → Target (External): /dev/sda
|
|
```
|
|
|
|
## What the Enhanced Script Now Does:
|
|
|
|
1. **Excludes USB stick** - Won't offer /dev/sdb as an option
|
|
2. **Shows drive details** - Displays size, model, USB detection
|
|
3. **Suggests configuration**:
|
|
- Internal: /dev/nvme0n1 (NVMe drives are typically internal)
|
|
- External: /dev/sda (USB-connected drives are typically external)
|
|
4. **User confirmation** - Asks you to confirm before proceeding
|
|
5. **Final safety check** - Shows exactly what will be wiped
|
|
6. **Type 'YES' confirmation** - Prevents accidental data loss
|
|
|
|
## Migration Process:
|
|
|
|
1. **Boot from USB** (/dev/sdb)
|
|
2. **Run migration script**
|
|
3. **Script will suggest**:
|
|
- Internal: /dev/nvme0n1 (476.9G TOSHIBA)
|
|
- External: /dev/sda (476.9G JMicron)
|
|
4. **Confirm selection**
|
|
5. **Type 'YES' to proceed**
|
|
|
|
This should prevent the wrong drive selection issue you encountered! |
