To prevent privacy leakage, you should wipe your hard drive before you abandon, sell, donate, or give it away. This operation removes files on the hard drive permanently. The question is how long does it take to wipe a disk. If you are curious about it too, read this post now!
From this post, you can find factors that affect the wiping time, rough time to wipe a specific capacity of hard drive, steps to wipe a disk, and possible issues in the wiping process. Explore the content now!
Factors that Affect the Wiping Time
Each sector on the drive must be overwritten to ensure the data has been erased. Compared with new drives, old drives need more time to be wiped. Besides, larger drives will take longer to wipe than smaller drives. Actually, the hard drive capacity is an important factor that decides the wiping time.
Generally speaking, the large the hard drive, the longer it will take to wipe. Don’t be strange that you need to wait for a longer period of time when you wipe a hard drive with a large capacity. The wiping method also makes a difference in the wiping time.
Most hard drive erasers allow you to choose a wiping method to decide how many passes over the drive the tool should make. A cursor wipe will perform a single pass of writing zero sequentially across the drive. As for the Department of Defense (DoD) method, it includes nine passes over the drive randomly marking zeros and ones during these passes.
Due to the randomly generated writing procedure used in these higher-level wipes, the time needed to finish the wipe operation is significantly longer per gigabyte than a single-pass sequential write wipe. Nevertheless, you should know that a single-pass wiping procedure won’t stop a data recovery expert from retrieving some portion of the data provided with enough time and resources.
It means that a single-pass wipe is not completely safe. So, it’s recommended to use higher-level wipes to erase the data permanently. In the next two tables, we list the wiping time that is required in two different wiping methods. You can take them as a reference.
|Drive Model||Drive Type||Drive Size||Drive Speed||Wipe Time|
|Western Digital Raptor||SATA||74GB||10,000RPM||19 minutes|
|Western Digital Caviar SE16||SATA||250GB||7,200RPM||1 hour, 20 minutes|
|Seagate Barracuda 7200.10||SATA||750GB||7,200RPM||3 hours, 11 minutes|
|Drive Model||Drive Type||Drive Size||Drive Speed||Wipe Time|
|Western Digital Raptor||SATA||74GB||10,000RPM||1 hour, 17 minutes|
|Western Digital Caviar SE16||SATA||250GB||7,200RPM||5 hours, 35 minutes|
|Seagate Barracuda 7200.10||SATA||750GB||7,200RPM||12 hours, 45 minutes|
How Long Does It Take to Wipe a Disk
How long does it take to wipe a hard drive? Depending on the hard drive size and the wiping method, the wiping process may take several minutes to several hours to complete. Here, we discuss the needed wipe time of three standards of hard drive capacity.
How long does it take to wipe a 500GB hard disk?
According to user reports, it would take you 3-4 hours to wipe a 500GB hard disk in normal cases.
How long does it take to wipe a 1TB hard drive?
The exact time depends on the specific wiping method. For instance, it would take you several hours to complete if you use third-party software to write over the entire hard drive. The case is different if you utilize specialized hardware that can write to the drive at a much faster rate. The wiping time will be shortened significantly.
Moreover, the speed of the computer or device you’re using to perform the wipe operation has an impact on the overall wiping time as well.
How long does it take to wipe a 6TB hard drive?
On average, it takes you several hours or several days to finish the wiping process. Assuming that the hard drive can write 100MB/s, it would take you 4 days, 39 minutes, and 22.5 seconds.

How to Wipe a Disk
After learning how long does it take to wipe a hard drive, you can perform the disk-wiping operation now! To do that, you need to make use of a hard drive erasing tool. Well, the Windows built-in utility Diskpart and third-party software like MiniTool Partition Wizard are worth having a try!
The Diskpart utility helps you wipe a hard drive by running a few command lines. To be specific, run “Diskpart clean” or “Diskpart clean all” command to erase the disk. How long does it take for Diskpart to complete using clean all? It takes about an hour per 320GB because it performs a secure erase.
As for Diskpart clean, it is faster than “Diskpart clean all” because it only marks the data on the target disk as deleted. The following steps illustrate how to wipe a disk via Diskpart.
See the difference between two commands by reading this post: Diskpart Clean vs Clean All: Choose a Way to Wipe Disks
Step 1: Hold Windows and R keys at the same time to call out the Run dialog window.
Step 2: Type diskpart in the Run window and then press the Enter key.
Step 3: In the pop-up window, type the commands below and hit Enter after each.
- list disk
- select disk # (The symbol # is the number that represents the disk to wipe.)
- clean (You can also replace it with clean all.)
Step 4: Wait for the finish of the wiping process.
You don’t need to download and install Diskpart on your computer. Instead, you just need to open it and run commands to wipe a hard disk. This is quite time-saving and convenient. However, it sometimes may prompt you with errors like Diskpart clean all stuck and Diskpart clean not working, which is annoying.
