I checked the data with the PC emulator. pic.twitter.com/qgzTtn9AuK
2017-01-04 23:28:58I test to write the dumped data to another disk. pic.twitter.com/aLTI5DPane
2017-01-04 23:33:10Ready to write is completed. I will test it from now. pic.twitter.com/E0uI93Ssmv
2017-01-04 23:37:01Writing on side A finished. Next, start writing on side B. pic.twitter.com/e2PN8H3Cng
2017-01-04 23:44:54Writing is completed. Check the disc. pic.twitter.com/lnOcFQSuRL
2017-01-04 23:48:56Although writing to the disk is completed, there is a problem on the side B. I will investigate it later. pic.twitter.com/yaCwNCtZbr
2017-01-05 00:32:09I will retest last night's disc writing test with another disc. pic.twitter.com/o66BNwfwxg
2017-01-05 18:42:42It is a continuation of last night. I start off by dumping again. pic.twitter.com/qV8BA6iIK6
2017-01-05 18:55:51There is a problem with writing on side B. The PC emulator is working without problems. :( pic.twitter.com/QpWqT9HWjq
2017-01-05 22:06:29This is a video showing the current situation. pic.twitter.com/3c0sgzauPz
2017-01-05 23:13:39I have a little time. I will test with Twin Famicom. pic.twitter.com/2HcVeQSjQG
2017-01-06 16:44:30Writing to another disk is complete. pic.twitter.com/0oi6w2Ty8W
2017-01-06 16:49:44Twin Famicom could write without problem. :) pic.twitter.com/nD3Zxy2zSo
2017-01-06 17:11:56It proved that there is no problem with the disk and writing tool. It seems there is a problem with the disk system.
2017-01-06 17:36:39The cause may be disk drive head or RAM adapter. pic.twitter.com/9M4FPBU4wR
2017-01-06 17:40:55I cleaned all the terminal parts. pic.twitter.com/NUSbObMOmF
2017-01-06 18:10:37Furthermore I cleaned the disk drive head. pic.twitter.com/SGBDz57814
2017-01-06 18:17:18I found the cause of why I can not write to disk. It turned out that the position of the magnetic head was slightly misaligned. pic.twitter.com/QfYMALD01x
2017-01-07 14:38:33If writing to the disc is necessary, very delicate adjustment is necessary. I tried it many times. pic.twitter.com/zxYUyxKOE7
2017-01-07 14:41:23I will write the data back to the test disk again. pic.twitter.com/IMT80J6sN4
2017-01-07 14:44:19Writing to the disk is completed. pic.twitter.com/PK47TWArcH
2017-01-07 14:54:52I have found amazing facts. There was also write protection on the main board of the disk drive. It is difficult to release this protection. pic.twitter.com/qAhmkBOns7
