Failed to write card, possible mark?

[alm450]

I have a 102 chip mounted on a bga board. I have been using it for some time with no problems. Recently I wrote a virgin image to the card and went to write spoonfed blocker back to it but it failed.
It said failed to write @ 9D80. I tried again and again, but nothing except a virgin image will write to the card.
Any ideas on how to fix this?

Thanks

What you trying to write with? If it is N2Edit, slow it down a tad...I use 50 50 for settings, in N2Edit 2.58.

Do you mean where it says command delay 250 and read byte delay ? change that to 50 each line? thanks.

yea use 50 on the command delay and 50 on the read byte delay ive always used these settings and never had no read or write problems with n2 edit 2.58
