what to delete on returned computer
I'm about to return the defective laptop and wonder if I should delete
the entire AppData folder that appears under my username. I think I've deleted everything else that I could, but if I should look at other things, let me know. Thank you, -- Jo-Anne |

Normally new machines like Dell etc have a factory restore feature. That would take care of anything. I'll grant that the paranoid person might suggest that there may still be some sectors of the HD not written to and might leave data behind, but I do think that's a bit paranoid. |

I'll see if there is a factory restore. That would certainly make things easier. Jo-Anne |

To remove paranoia, I use EaseUs Backup (the free version). It has a wipe function, aswell as a very useful clone feature if you buy a new disk. -- I contend that we are both atheists.

I'm not all that paranoid, especially since I had put very little on the machine. I did manage to find the factory restore and am in the process of doing it right now. Dell's instructions were wrong (directing you to an option that doesn't exist), but I picked what seemed the best alternative, and it's working. I'll bookmark your post and will probably download the program you mentioned--for future use. Jo-Anne |

Even formatting doesn't wipe a hard drive. This is what "dd" is for :-) It can quite nicely write zeros in a partition, and do a single pass. This is a house-cleaning script I use, intended for a certain FAT32 partition. What I would do (for this example), is delete all the files on the E: partition. (The Ridgecrop formatter can make this really fast.) Now, the partition has no visible files, but any erased files are still there (hiding). Once the partition is empty, I run the script. dd.exe if=/dev/zero of=E:\big01.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big02.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big03.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big04.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big05.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big06.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big07.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big08.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big09.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big10.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big11.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big12.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big13.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big14.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big15.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big16.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big17.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big18.dd bs=65536 count=65535 dd.exe if=/dev/zero of=E:\big19.dd bs=65536 count=65535 Since FAT32 has a 4GB limit, each "write" operation can only erase ~4GB. Those commands are just under the limit. Each file created will be 4GB in size and all zeros. So 19*4=76GB of zeroing. At the end, I would erase the 19 files, and then E: would be as clean as a whistle. No data recovery software can find anything after that. I could then install an OS if I wanted, restore some stuff, and there'd be no "left-overs" to recover. (Using the Ridgecrop formatter should also remove the filenames in the FAT.) On NTFS, you can just use one command and wipe the entire partition. Like this dd.exe if=/dev/zero of=E:\big01.dd bs=65536 The file in this case, should span the entire E:\ partition, before the command complains it has run out of space. The "dd.exe" is from here, version 0.6b3. http://www.chrysocome.net/dd Paul |

Even formatting doesn't wipe a hard drive. Thank you, Gene. I guess if there's a next time, I'll do better at getting rid of my data. Fortunately, there wasn't much on the computer. The only personal files were from Thunderbird and Firefox, and at least those would have been deleted, even if not fully erased. -- Jo-Anne |
