Description 

DCO in Use 

Yes 

(ATA Devices Only) Yes, if the ATA DCO 

feature set is being used to reduce the 

apparent capacity of the hard disk. 

AMA in Use 

Yes 

(ATA Devices Only) Yes, if the ATA AMA 

feature set is being used to reduce the 

apparent capacity of the hard disk. 

Security in Use 

No 

(ATA Devices Only) Yes, if the ATA Security 

feature set is being used to password protect 

the contents of the hard disk. Note that ATA 

Security locked drives cannot be used for 

TD2u operations. 

4.8  Disk utilities (Menu 5) 

The TD2u offers several utilities to assist with the processing of drives. These utilities can 

be found in Menu 5. 

4.8.1  Format (Menu 5.1) 

When using disk-to-file imaging, the destination drive must be formatted with a file 

system that is recognizable by the TD2u. The TD2u only supports formatting drives with 

the exFAT filesystem. However, the TD2u will also accept destination disks that are 

formatted as FAT32. The FAT32 file size limit is 4 GB. The exFAT file size limit is 16 EB 

(16,000,000 TB). When file sizes are larger than 4 GB, exFAT should be used. 
From the formatting menu you can manually format either the destination disk or a USB 

mass storage device attached to one of the TD2u USB ports. 
1.  From the Main menu, use the arrow keys to navigate to 

Disk Utilities

 (Menu 5) and 

then to 

Format

 (Menu 5.1). 

2.  Select 

Format Destination

 (Menu 5.1.1) or 

Format USB Accessory

 (Menu 5.1.2). 

3.  Press the 

[Start]

 soft key to confirm your selection. The formatting task begins.

Traditionally, hard drives have had an internal structure built around sectors of 512 bytes. 

Newer drives, especially those with capacities greater than 2 TB, feature the Advanced 

Format (AF) structure that uses internal sectors of 4096 bytes. Such drives still support 

I/O transfers that reference 512-sectors; internally, the drives map these references to 

the internal 4096-byte physical sectors. Implicit in this mapping is the need to 

accommodate writes that alter the data stored in just a portion of a physical sector. This 

is accomplished by an inefficient read-modify-write cycle.
