Larz, minimum required for complete erasure of accessible sectors is a single pass overwrite with either pseudo-random or zeros. If you do not plan to reusue the drive and just want the data gone and the drive never resold or reused just take it apart and throw the platters in a nice hot fire, that'll do it *grins* So connect it to the best SATA or SCSI port you have available to get the most out of the drive. Bear in mind that if you have the 1TB drive in a USB caddy on a USB2.0 port you'll be restricted in write speed by the slow USB2.0 port to around 30MB/S. So divide the size 1000,000MB by the average write speed in MB/S and you have an estimate of each pass of writes you choose. So keep drive as cool as possible to maintain optimal write speed and realise it will be slower towards the center of the drive, the first 10% to 20% of the surface will be the fastest portion of the disc. On a 1TB hard drive because of the recording technology used there is no need to do multiple passes. No criminals, computer shop, data recovery firm or any known nation state would be able to recover any data. And all file erases SHOULD extend every file to the end of the last logical cluster and then overwrite the data. Freespace erase should optionally offer wiping of all files cluster tips. Note there also is no mention of a significant potential data leak in an area known as "cluster tips", when free space or a file is erased the erasure should erase the slack space between the CURRENT end of the file and the end of the logical cluster because that slack space can contain data if a file has been truncated a little or if it previously held other data. It does nothing more or less than CHKDSK does, including sometimes making files and folders inaccessible when it repairs repairs a slightly faulty file system! Use with caution! Note "Disk Tools" is just running Microsofts CHKDSK.EXE utiity in a custom shell. thanks alot magoshare!įor other visitors to this site the 4.3 version on their site accepts the giveaway license. and seeing as we are given only 4.2 there MUST be a few KNOWN bugs in this giveaway version. No mention of what was new in all the previous versions. Sadly cannot seem to find a complete version history on their site just a single: This is derived from the same source as Super Eraser given away before, not possible to say which company develops it and sells it to be rebranded by the other.
