⌨️Disk Initialization

Initial setup and configuration for new IODD devices and internal disks.

hashtag
1. First-Time Setup Sequence

If you are installing a new disk for the first time, follow this specific order:

  1. Detection: Once the IODD is recognized, an initialization message will appear in your OS disk management tool.

  2. Encryption First (Optional): * If you intend to use hardware encryption, you must set the password on the IODD hardware first before initializing the drive in Windows/Mac.

    • ST400, LK100 & MINI PRO: Set the 2nd Password first, followed by the 1st Password.

  3. Perform Full TRIM (Highly Recommended): Before creating partitions, we strongly recommend running the IODD TRIM Tool to perform a Full Device TRIM. This ensures all flash memory blocks are properly initialized to a clean state, providing optimal write speeds and extending the SSD's lifespan. (If you have already created partitions or are currently using the drive, you can use the Free Space Only TRIM feature to safely optimize it without losing data.)

  4. Disk Initialization:

    • Modern Models (ST, MINI PRO, LK100): Supports both MBR and GPT. GPT is recommended for drives over 2TB.

    • Legacy Models (2531, 2541, MINI Legacy): Supports MBR only. GPT is not supported.

    • Note: Legacy models have a hardware limit that only recognizes the first 2TB of a drive.

  5. Partitioning & Formatting:

    • Format using NTFS, exFAT, or FAT32.

    • Note: FAT32 has a 4GB file size limit. NTFS/exFAT is recommended for ISO/VHD files.

    • VHD Tool++ note: If you use VHD Tool++, exFAT is recommended. On some Windows versions/locale settings, NTFS may cause occasional time/timestamp format errors in the tool.

    • ST/MINI PRO: The IODD data partition does not have to be the first partition on the disk.

  6. Safe Removal (Crucial): Always use Safely Remove Hardware before disconnecting. Failure to do so with NTFS can lead to the "ASSERT" error.

  7. Reconnect & Verify: Reconnect the IODD.

    • Modern Models (ST, MINI PRO, LK100): If files are not visible, hold the [4] key for 3 seconds to manually select the correct partition.

    • Legacy Models (2531, 2541, MINI Legacy): This partition selection hotkey is not supported. Ensure your data is on the first primary partition. (For 2541, long-pressing [4] only rescans the current partition).

2. Fixing Initialization Failures (MBR → GPT → MBR Trick)

If the drive fails to initialize or displays errors, try this cycle:

  1. Connect the HDD/SSD directly to a PC (if possible) or via IODD.

  2. Initialize it as GPT.

  3. Then, immediately re-initialize it back to MBR. This process can often clear corrupted partition table metadata that simple formatting cannot fix.

3. Voltage Check

Monitoring voltage is crucial for data integrity. Press [3] on the keypad to view the current V-voltage.

  • Lowest/Minimum Voltage: Some models (ST/2541) track the lowest voltage detected since connection. This is the most critical value for stability.

  • Current Voltage: Displays the real-time BUS voltage.

Low Voltage Warning (< 4.65V) This is critical. Large file transfers may fail, or the disk may disconnect randomly. You must move to a rear PC port or use a powered USB hub immediately to prevent data loss.
