What does spin-down mean

Using SeaTools

Selecting a test to run

The menus contain a number of diagnostic tests. Select the test you want to run on the selected hard drives

 

In the SMART exam, the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) - Examines the hard drive log kept by the hard drive during normal operation to quickly determine if the hard drive has previously had problems. A failed test is referred to as a "SMART trip" and corresponds to the prognosis of a prompt failure. If the SMART exam fails, a warranty exchange is recommended.

Short DST, or Drive Self Test, is a comprehensive diagnostic routine built into the hard drive's firmware. Firmware is the machine language that is installed on the hard drive and controls its behavior. The DST is absolutely secure. If the short hard drive self-test fails, a warranty exchange is recommended.

Brief general test is similar to the built-in DST function, but implemented in software and does not require the hard drive to support special commands. The short test is absolutely secure.

Long general test examines the entire hard drive for defects. This test takes a long time to complete. Since this test checks every sector of the hard disk, the time required for this depends on the speed and capacity of the hard disk. Often times, it takes 3 to 5 hours per terabyte (TB) to run on the highest capacity hard drives. The test can be canceled at any time without damaging the hard drive. The long test is absolutely secure.

The Fix All function repairs bad sectors if possible. For the "Fix All Fast and Long" function, the F8 key must be pressed. This confirms that you want SeaTools to attempt to repair any unreadable LBAs (sectors) it detects. It is important to know that data in a sector that is bad and unreadable is already lost. For more information on this topic, see Help Topic: Bad Sector Found.

Acoustic Test - (Spin Down) Sometimes a defective hard drive makes strange noises. Often, however, the power supply and processor fans are mistaken for the hard drive. In this test, the hard disk is paused like in the sleep mode of the energy management (spin down). If the hard drive was the source of the noise, the noise will stop. If the noises can still be heard, you can exclude the hard drive as the source.

Set Max LBA - Occasionally a hard drive may be too large and need to be reduced in size to a smaller capacity. Similarly, a reduced capacity hard drive may need to be reset to its native maximum capacity. There are three choices in this section

The menu Advanced tests (Advanced Tests) contains options that could result in your data being erased or the drive becoming unusable for your system. If you continue, you could lose data.

With the function Erase Overwrite Full the entire device is erased by writing the value zero to each sector. This process will take some time to complete, depending on the speed and capacity of the hard disk drive. WARNING!!! All data on the hard drive will be lost. WRITING A DATA PATTERN WITH ZERO-FILLING IS A DATA DESTROYING OPERATION. IT CORRESPONDS TO DELETING DATA FROM THE HARD DRIVE.

Seagate is not responsible for any loss of user data. Erase Drive is only available for Seagate, Samsung, LaCie, or Maxtor hard drives.


Attention: The startup disk is sometimes difficult to recognize, so be sure to make sure that the startup drive is not selected.

Be very careful as using the SeaTools Bootable Erase options will result in loss of data. Seagate is not responsible for any loss of user data.

If it is your own hard drive, you should always have an up-to-date backup of your important data.

If it isn't your own hard drive and the original owner no longer has ownership of it or the data stored on it, you may still be responsible for the data in your possession. To protect yourself from possible liability claims and to protect the privacy of the previous owner, you should remove all data by performing a data erasure on this hard drive.

Not all hard drives support the following advanced erase commands. If the drives support the command, the software displays a selection menu.


Erase Write Same - Use this option to start a WRITE-SAME erase operation on the specified starting LBA. Use “0” to make the starting LBA the same as the beginning of the hard drive. The last sector (Max. LBA) on the hard disk is indicated at the top of the window. The Write-Same data pattern corresponds exclusively to zeros (0000 ... etc.) for the specified area.

The “Erase Write Same” option is faster than “Erase Overwrite Full”. This is especially true when erasing USB drives because the write-same process can be three to five times faster there.

On SCSI devices, this option uses the writesame16 command. On ATA devices it uses the SCT function “writesame”.


Erase Sanitize - Sanitize Overwrite takes a long time to complete on hard drives, approximately three (3) hours per TB (terabyte). Once this command has started, the Overwrite Erase process must be terminated before the hard drive can return to normal operation. Even if a reboot is performed during the Overwrite Erase process, the hard drive will continue from where it left off until the end of the erase process. The sectors can be automatically reassigned (repaired) while this function is running.


SED Crypto Erase (PSID) - Self-Encrypting Drive Instant Secure Erase. This menu appears if the hard drive supports hardware encryption. As with “Full Erase”, this command also destroys access to all user data on the hard disk, but by deleting the encryption key for the hard disk, which only takes a few seconds.

If you selected "SED Crypto Erase", enter the PSID (Physical Security IDentification number) password, which is noted on the label of the hard drive. The PSID is a 32-digit sequence of numbers and capital letters printed on the label. There is no electronic query for this number, so the hard drive has to be removed to read the PSID number. Many hard drives have a PSID code on the label, but they are NOT labeled Seagate Secure. These hard drives do not support RevertSP cryptographic erasure.

Enter the PSID without spaces. FIVE attempts are allowed before the system must be turned off and on. Reading can also be done with a 2D barcode reader.

The "SED Crypto Erase" command is very quick and takes less than one (1) second to complete. It changes the internal encryption keys that are used on user data, rendering any previous data unusable. With this command, a RevertSP operation according to the Opal SSC specification is carried out on a hard disk with self-encryption (SED). This process is available on any Seagate SED hard drive marked “Seagate Secure” on the label. When the process is complete, the hard disk is “like new”: All user data has been cryptographically deleted and all other settings have been reset to the factory settings.
