Disk

In the Disk functionality, you can access detailed information about your disks, check their health status, and perform maintenance operations like disk health checks.

Management

Through the buttons in the management tab, you can perform the following operations：

• Overview: You can view the device model, disk slots, and other pertinent information.
• Disk: Disk-related operations cover various tasks, including:
  • Bad block scan: Conducting bad block detection on disks to identify any faulty sectors.
  • Remove/Enable: Removing a disk is akin to physically unplugging it from the TNAS, causing the system to no longer recognize it. Re-enabling a removed disk simulates the action of manually reinserting it.
  • Set: Activating disk write caching and enabling bad sector warnings to enhance disk performance and reliability.
  • More: Performing comprehensive disk performance tests, secure erasing, disk wiping, mounting and unmounting disks, setting permissions, and executing other related operations.
• System Disk: You can perform operations such as adding, migrating, or deleting system disks.
• S.M.A.R.T.: Monitoring the health status of disks to ensure their optimal performance.
• Disk Log: Recording all disk-related activities, including disk insertion and removal, secure erasing, S.M.A.R.T. testing, and more.

The table below outlines the available disk operations and their respective meanings within the "More" features section. Please consult this list when undertaking different operations.

Status	Meaning of Status Indicators
Benchmark	Conducting hard drive read/write performance testing provides a comprehensive overview of key indicators such as IOPS, read/write speeds, and latency parameters of your hard drive.
Secure Erase	Secure erasure is primarily employed to prevent data leaks and safeguard sensitive information. During secure erasure, the system will overwrite the disk with random 0s and 1s until all disk space is filled. Disks that undergo secure erasure are irrecoverable. Note that secure erasure is time-consuming, and interruptions could potentially damage your disk; therefore, please do not interrupt the process.
Wipe Disk	Erasing a disk is equivalent to initializing it, resulting in the removal of all array information, partitions, and file systems on the disk.
Mount Disk	You can directly mount disks with different file systems to the TNAS without any formatting and easily access the data on the disks (only Single-type disks are supported; RAID array disks are not supported). Currently, TNAS supports a wide range of file systems, including FAT, FAT32, NTFS, EXT2, EXT3, EXT4, ExFAT, Btrfs, and HFS+.
Unmount Disk	Unmount a disk that is already mounted.
Permissions	Configure user group permissions for the mounted disks.

Note

1. The secure erasure and disk erasure functions can only be applied to disks that are currently not in use. If a disk is part of a storage pool, please delete the related volumes and the storage pool itself beforehand. For mounted disks, make sure to manually unmount them first. Once these steps are completed, you can utilize these functions.
2. Removing a disk from an array will cause the array to degrade; the removed disk will be unusable and needs to be enabled before it can be used again.
3. USB devices cannot be subject to secure erasure, erasure, mounting, or unmounting operations in the disk interface. If you need to operate on USB devices, please go to the USB function interface.

How to Add a System Disk?

1. Click the "Create" button, select the disk you want to add as a system disk, and click "Confirm".
2. Verify your selection in the pop-up prompt and click "Confirm" again.
3. The system will check the partitioning of the selected disk:
   • If the disk does not meet the requirements for a new system partition, it must be formatted. Click "Confirm" once more to proceed.
   • If the disk meets the partitioning requirements, no further confirmation is needed.

How to Migrate a System Disk?

1. Click the "Migrate" button, select the disk from which the system will be migrated, and click "Next".
2. Choose the target disk for migration and click "Confirm".
3. Verify your selection in the pop-up prompt and click "Confirm" again.
4. The system will check the partitioning of the selected disk:
   • If the disk does not meet the requirements for a new system partition, it must be formatted. Click "Confirm" once more to proceed.
   • If the disk meets the partitioning requirements, no further confirmation is needed.

Note

1. System disks can only be configured on disks of the same type.

• When adding a system disk, you can only select disks of the same type as the current system disk.
• When migrating a system disk, if you wish to change the disk type, you must select all current system disks for migration.

2. After successful migration, the original system disk can no longer function independently as a system disk.
3. A non-current system disk refers to a disk with a system partition that contains a TOS system not currently running. Before deleting this system, the disk cannot be added or migrated as a system disk.
