Solved How to Wipe Drive of Epson Equity II+

October 16, 2010 at 16:52:18
Specs: DOS 3.3, Maybe 640KB
I have an Epson Equity II+ that has DOS on it. The computer is from about 1989. I want to wipe the hard drive. The A drive is a 5.25 floppy drive and the B drive is 3.5 floppy drive. I bought WipeDrive and it won't work. I cannot boot from the B drive. I think I am having issues because the RAM is so low. It also has a lithum battery which is now dead. Is there software out there that I can use with this old computer? Is there a command that I can run at the C prompt to delete the hard drive? Some individuals say that drilling holes will destroy the disk and that is the only way with an old computer. I would perfer to wipe out the hard drive with software. I hear that reformatting the drive is not enough.

Do you need to wipe it or just delete everything? You can format it after booting from a dos bootdisk or run FDISK and just remove the partition. The data will still be on the drive but there will be nothing so show where the files and directories begin and end.

Wiping the drive will write zeros to it thereby overwriting the data.

As I mentioned above, WIPEINFO from a dos version of norton utilities should work to wipe it. If you still want to wipe it I can send the necessary files. Post back your email address or send me a private message.

The quick and easy way is to remove the drive and hit it with a sledgehammer. If you wish to use software a full format will be proof against all but the most determined hackers. Does the drive contain data that is worth that kind of effort to obtain?

If the drive cable has the 7-wire twist you should be able to boot from the 3.5 by swapping its position on the cable with the 5.25 and then making the necessary adjustments in cmos/bios setup. (You may need setup disks to access the cmos.)

If the drive cable doesn't have the twist you'll need to change their DS (drive select) jumper settings. The booting (a:) drive needs to have the lowest DS--it may be DS0 or DS1, depending on how they're labeled. The B: drive will have the next higher setting, either DS1 or DS2.

Not sure what software is best to wipe that drive but I imagine WIPEINFO from any dos version of norton utilities will do it.

I do not know what you mean by "drive cable has the 7-wire twist". To find the DS jumper settings I have to remove the cover from the unit, yes? I am a database person not a hardware person so I am not familar with the hardware side.

Here's a pic of a cable with the twist:

http://www.pcguide.com/ref/fdd/conf...

That particular cable has 4 floppy connectors. That doesn't mean you can hook up 4 drives to it. It means you can connect either type of drive--a 5.25 that likely has a slide-on connector or a 3.5 that likely has a pin connector--to either connection.

Most newer drives are either hard-wired to the second DS or the jumpers aren't accessible. So you need to use one of those cables for newer drives. Cables with a seven-wire twist allow the bios to distinguish the two separate drives even though they are jumpered the same.

Drives that are meant to have the DS jumper changed by the user will have the jumpers accessible. The drives in your Equity II will probably be that way. But yeah, you'll have to open the computer case and probably remove the drives in order to get to the jumpers.

Or if it already has a cable with the twist then their DS settings are the same and just swap their positions on the cable and change the drive type in cmos/bios setup. In that case you don't need to mess with their jumpers.

Thanks for the education on the harddrive. I was able to open it up and make the changes. I do have the 7-wire twist. The issue is finding the software to wipe the drive. DBAN didn't work. WipeDrive didn't work. And KillDisk didn't work. My computer is prior to 286 and it seems that this software works with only 286 and greater.

Can anyone suggest any other software? I do not know how to get an older version of WIPEINFO from any dos version of norton utilities. I tried surfing the internet and could not find it available.

I want to get rid of the PC. I am going to give it to a recycling center. There is sensitive information on the PC that I don't want anyone to get a hold of. I am worried about identity theft. I have sent you a private message.

OK, I sent it. Let us know how it goes.

I didn't mention it in the email but you can type WIPEINFO/? at the prompt to get a description of the available switches but you should be able to wipe the drive OK using the options when you run it.
