中国DOS联盟

My USB mobile hard disk is a "Keshuo" disk enclosure, the chip is ALI-M5621, and it's an IBM 2.5" 30G hard disk. DOS doesn't start normally: I can boot with the third and fourth items of DOS (7.10), but when I plug in the mobile hard disk, it freezes. First, I boot with the mobile hard disk, and in DOS, I can display the partitions and capacity of the "mobile hard disk", but finally it shows up to: Adapter not Presene. Freezes. The same thing happens with the digital camera; as soon as I turn on the power, it freezes. I don't know what to do?

Can the expert help?
Thanks in advance!!!

I also have the same problem. Which expert can help?

Bump!

Where are the experts???

Little brother is new here, and I dare to say a few words: I suspect it's a problem with the mainboard power supply. May I ask if you can use mobile devices (I mean the problematic mobile hard drives and digital cameras, etc.) normally under Windows? If there are also situations like死机or no response, then it must be because the mainboard power is insufficient. You can take power from the PS/2 port. Otherwise, I don't understand.

（注：“死机”翻译为“system freeze”更专业，但根据用户要求尽量保持贴近原文表述，这里暂时保留“死机”的直译；另外“没反应”翻译为“no response”）

Agree with the above floor
LZ, please check powering from PS/2
