jin Because h27u518s2c is a high-capacity memory, maybe has some bad blocks. If it has bad block, the operation will be failed. Go back list [ Posted:2012-11-01 13:00:07 ]

jin The new chip like this also have block failure rate. And also you can try to download our latest software4.5.1 and do the "system update" to update firmware to 18.0. [ The message is modified by jin ] Go back list [ Posted:2012-11-06 16:31:55 ]
