i have the same problem.. it has the same symptom in slower speed, always problem with verify process.. "Verify failed,address 0x000000,Device=0xff,Buffer=0x002" MX25L1005AMC ----------->> MX25L1005MI (ID check pass, meanwhile using MX25L1005MC -->> ID Check fail) I already clean the ic pin and the adapter.. Any solution for this problem ?
