hello there what chips are you attempting to erase, and the dip switch configuration ?

it sounds as though it could be a voltage setting fault. are you using external 12v in or USB? i found the later to be a little flakey when programming so I decided to goto the 12v dc instead.

Thanks for your quick reply it is a chip from the 250 modem and im using a multi voltage power supply from maplins set to 12 volts. It gets to 3% on the erase and says its done but when i check it says not empty. Thanks

alas I am new here, so I dont know what a 250 modem is, would you have the chip information like serial number on the chip ?

a lot of EEPROM (the non UV kind) can require upto 18 volts of juice to format. but obviously this depends on the chip itself.

another question i must ask is, did you change the switch bank to the correct power level for the chip? (there should be a diagram on the screen when you select chip type)

if all else fails, OR i am beging to talk blurb again, take some nice hires-pics of the programmer (the settings) and chip then postie here

Hardware Pr0n is always welcome to me
