X24C01 read error

[pinch]

What computer configuration do you use ?
USB power or external ?

what is the difference between standard 24c01 and x24c01
can they be interchanged?

[TWINGO]

I am trying to read a X24C01 in circuit with soic clip but keeps getting verifying error.
I use a X-prog T and DIP to SOIC adapter cable.
What am I doing wrong ?

I've some problem to write 24Cxx. I use IC-prog with serial port. The problem was windows rs232 drivers. If I use WIN98 I've not problem. I've resolved with usb adapter. I use the old wafer card programmer (ludipipo)... It work great for immo chip of edc15...
