Question 2

Battery-Powered Operation Time for TAINER

Accepted Answer

How long does TAINER operate on battery power?

The battery operation time of TAINER depends on the type of installed SSD and the memory cards being used. This is because different memory cards draw varying amounts of power. For example, a CFexpress (CFe) card consumes approximately 1.5A, while an SD card typically draws around 0.6A. Due to these differences in power consumption, the operating time of TAINER will vary.

Since TAINER has a fixed battery capacity, higher power consumption results in a shorter runtime. To prevent data corruption, TAINER includes a power protection circuit. If the battery level becomes too low and power becomes unstable, TAINER will automatically shut down before reaching a critical level to avoid hardware malfunctions.

How can users determine if the battery is sufficient for their backup task?
We strongly recommend fully charging TAINER before use. TAINER's battery gauge operates in four levels, each indicating the remaining battery capacity:
 • Full (3 bars): More than 70% battery remaining
 • Two bars: 30–70% battery remaining
 • One bars: 5–30% battery remaining
 • Empty (1 bar or flashing): Battery is critically low and will shut down soon

WD Red SA500 2TB: This model is not recommended because it has a high power consumption which can overburden the TAINER's power system, leading to substantially reduced battery life.

Timetec 35TTQNM 2TB: This SSD has a critical flaw where it may become completely non-responsive during a security erase operation. If this occurs, the SSD becomes unusable and cannot be recovered.

KingSpec 4TB: The security erase function on this SSD does not operate correctly. It may indicate that data has been erased, but in reality, the data remains intact. Without a reliable secure erase feature, the SSD cannot be reset to its optimal speed, which is why we do not recommend this model for use with the TAINER.

For these reasons, these SSDs are deemed incompatible and should not be used with the TAINER to ensure the integrity and performance of your data backup processes.

Question 4

TAINER sometimes does not detect my SD card or microSD card (via adapter). What is the reason?

Accepted Answer

Intermittent detection usually comes from two causes:

1) SD Card Contact Issues (Most Common)

If the gold contact pins on the SD card are dirty or oxidized, the card may be recognized only occasionally.

How to fix:
 • Clean the gold contacts using a soft rubber eraser
 • Remove dust or debris from the card and the SD slot
 • This simple cleaning solves most cases.

2) Compatibility Issues with microSD + Adapter

For microSD cards, the electrical signal travels through multiple points:

microSD → Adapter contacts → Adapter internal circuit → TAINER SD slot

If any part has poor conductivity or low-quality components, the card may fail to be detected.

We have verified that:
Some Kingston microSD cards used with certain Lexar SD adapters show detection problems in TAINER. The same microSD card works normally with Samsung or SanDisk adapters.

Recommended solution:
 • Try a different microSD-to-SD adapter, preferably Samsung or SanDisk

If detection problems continue after cleaning the contacts and changing the adapter, please contact our support team for further assistance.

Question 5

TAINER Not Detected as an External USB Drive on Your Computer

Accepted Answer

If TAINER is not detected as an external USB drive on your computer, try connecting TAINER directly to the computer instead of using a USB hub. Some USB hubs omit USB 2.0 signals, causing TAINER to think it is connected to a USB charger rather than a computer, and thus it will not be detected.

To operate TAINER as an external USB drive, follow these steps:

• Connect the USB cable to the USB Type-C port (located on the right side) of TAINER.
Refer to the image below to ensure the proper connection:
https://static.wixstatic.com/media/b56a9d_59b8ceb74d814d5e87fad915bf831c6a~mv2.png

• Ensure the USB cable is connected directly to the computer.
Avoid using USB hubs that may omit USB 2.0 signals. TAINER requires these signals to detect a computer properly.

• Device Detection Process:
    • When the USB cable is connected to the Type-C port, TAINER checks whether the connected device is a USB power source or a computer.
    • If connected to a USB power source, TAINER will only use the USB power.
    • If connected to a computer, TAINER will display a menu asking you to select one of the following options:
a. Connect to the computer (draw power from the computer)
b. Connect to a smartphone (self-powered, not drawing power from the smartphone)
c. Just draw power from the connected device

Question 7

TAINER Network Performance: What to Expect (LAN & Wi-Fi)

Accepted Answer

Q1. What upload speeds can I expect via wired LAN?

A. TAINER’s hardware limits wired upload to up to 16 MB/s. In real-world use, plan for about ~10 MB/s (≈80 Mb/s) due to protocol overhead, encryption, and cloud API behavior.

Q2. What upload speeds can I expect via Wi-Fi?

A. TAINER supports 802.11n (2.4 GHz) only. In our lab we saw ~4–5 MB/s (≈32–40 Mb/s); in typical environments it can be as low as ~1 MB/s (≈8 Mb/s) due to 2.4 GHz congestion and interference.

Q3. Why is LAN capped at 16 MB/s?

A. It’s a hardware limitation of the Ethernet and system architecture. Firmware updates can improve stability and small-file efficiency, but cannot exceed the 16 MB/s ceiling.

Q4. Is TAINER meant to replace high-speed local backup?

A. No. TAINER’s primary strength is on-device, multi-drive copy/backup. Cloud upload is for convenience and off-site safety, not maximum speed.

Q5. Will future updates make it faster?

A. We continuously optimize stability and small-file handling. However, due to hardware, wired uploads won’t exceed 16 MB/s and Wi-Fi will remain limited by 802.11n 2.4 GHz.

Q6. Can I use a third-party Wi-Fi adapter?

A. No. TAINER only supports the included Wi-Fi dongle. Third-party Wi-Fi adapters are not supported and may not be recognized or may cause instability.

Question 8

Incremental Copy Feature on TAINER

Accepted Answer

TAINER supports incremental copy, which allows copying only newly added files. This feature works in the following scenarios:

1. Copying to a single target, either to the internal drive or an external USB drive.
2. Copying to multiple devices simultaneously (e.g., copying to both the internal SSD and an external SSD at the same time).

However, we have disabled the incremental copy feature when performing a 'make secondary copy' from the internal SSD to an external USB drive. This decision was made to avoid potential conflicts that could arise if incremental copy is used with both multi-copy and 'make secondary copy' operations.

We are working on resolving this conflict and will release an updated firmware to re-enable this functionality in a future update.

Question 13

Enhanced Stability Measures for ExFAT File Systems in TAINER

Accepted Answer

https://static.wixstatic.com/media/b56a9d_59f8546d500c4fc8a24c16575f5ff5b6~mv2.webp

When reading data, TAINER accepts memory cards formatted in HFS+/UDF/exFAT/FAT32. However, when writing data, TAINER writes only to drives formatted in exFAT. This means that to work with TAINER, the internal SSD must be formatted in exFAT. This requirement also applies to USB external SSDs.

We use exFAT because it is supported by nearly every operating system, including macOS and Windows, ensuring compatibility with most computers.

However, since exFAT is an unjournaled file system, disruptions during critical operations can corrupt the file system, especially since most operating systems do not write data directly to the disk. Instead, they hold data in a buffer and write it later, at an opportune time. The 'safe removal' feature flushes this buffer to the disk. If a USB drive is removed without using 'safe removal', the buffered data may not be written correctly, which can corrupt the file system and result in data loss.

To mitigate these risks, ClouZen has implemented the following measures:
1. Immediate writing of data to the disk to prevent inconsistencies caused by buffered data.
2. Completion of all file system-related critical access before the start of actual data copying. These critical accesses are completed within one second, minimizing the risk of file system corruption.
3. During data transfer, we avoid accessing critical sections of the file system. Thus, in the worst-case scenario, only the file data may be incomplete, with no risk of file system corruption because we do not touch the critical sections during copying. Situations such as memory card removal, sudden power loss, or other errors during copying will not affect the file system.

This approach makes TAINER unique in its ability to protect the file system, allowing us to continue our business without occurrences of user data problems.

One note of caution: While TAINER itself is robustly designed for all possible scenarios, USB card readers or USB SSDs connected to TAINER are not perfect. Additionally, TAINER has limited power capacity. If you use a high-power-consuming USB card reader, such as an SxS, we recommend attaching external power to TAINER. Drawing too much power through USB can destabilize the USB power voltage, increasing the chance of misoperation in connected USB devices.

Question 14

How does the TAINER's Incremental Copy Mode work?

Accepted Answer

The TAINER supports incremental copying, which allows users to efficiently manage their files. Here’s how it works:

1. Initial Copy: Insert your memory card into the TAINER and perform an initial copy of the files.
2. Add More Photos: Continue using your memory card to take additional photos.
3. Subsequent Copies: Reinsert the memory card into the TAINER. It will automatically detect and copy only the new files added since the last copy.

Conditions for Incremental Copy: To activate the incremental copy mode, one of the following conditions must be met:
 • The memory card must initially contain at least one file larger than 1GB(1024*1024*1024 Byte).
 • Alternatively, it must contain more than 11 files where the total added file capacity exceeds 32MB.

Once these conditions are met, the TAINER will display the Incremental Copy (Update) option on the LCD menu, allowing you to proceed with selective file copying.
