Difference between HDD Wipe and HDD Low Level Format ?

As subject:

what are the differences between HDD Wipe and HDD Low Level Format?

HDD Wipe Tool:

This freeware HDD Wipe utility will erase and re-certify a SATA, IDE or SCSI hard disk drive with any size of up to 281 474 976 710 655 bytes. Will work with USB and FIREWIRE external drive enclosures. Low-level erasing of Flash Cards is supported too. HDD Wipe Tool will clear partitions, MBR, and every bit of user data. The program utilizes Ultra-DMA transfers when possible.

HDD Low Level Format Tool:

This freeware Low Level Format utility will erase, Low-Level Format and re-certify a SATA, IDE or SCSI hard disk drive with any size of up to 281 474 976 710 655 bytes. Will work with USB and FIREWIRE external drive enclosures. Low-level formatting of Flash Cards is supported too. Low Level Format Tool will clear partitions, MBR, and every bit of user data. The program utilizes Ultra-DMA transfers when possible.

The descriptions are very very similar ...

a WIPE is only a Zero Fill

a so-called "LLF" is a Zero Fill, plus a scan for bad sector, bad sectors then are mapped out and simply disappear. They won't appear from a chkdsk command, you can only guess bad sectors have been found if the disk size has been reduced from before the Reinitialization.

http://en.wikipedia.org/wiki/Disk_formatting

Wiki advocate the term Reinitialization rather than LLF.

Important Note :

On the same disk, I have done a Reinitialization with
1) Seatools 1.09
2) MAXLLF 1.1

The Seatools was 10X fastest than the Maxllf, and it left errors on the disk (a Windows format hung à 63%).

The Maxllf took hours to complete, but really did the job.
The Windows format did go 100%.

No difference in my opinion .

As far as my thinking goes, After low level format is done data can be recovered using data recovery software.
But When the disk is wipe clean data recovery is not possible in that case.

u cannot recover data after low level format .
