I don't know if the exam is over? Shen Jie, looking forward to your new version. Your version 2.0 can only see drive A and drive C on my two machines. If the boot disk is like this, it's not meaningful, because I can't enter other drives. My system backups are all on the last drive. If I can't enter other drives, I might as well just make a Windows 98 boot disk. So I hope you can quickly release a new version of the improved Chinese boot disk. I've used Wengier's disk, and his can identify other drive letters. I've used several DOS boot disks. Either there are too few tools and they're not practical for me, or they can only identify drive A and drive C. I'm very satisfied with the tools here, but there are a few that don't seem to have much special use. It's not because they're useless, but just in comparison, the possibility of using them is small. Like the disktool inside, I think it's not very useful. It's not as useful as the original KV3000 antivirus. Generally, partition tools, low-level format tools, hard disk repair tools, and antivirus tools in the boot disk are very practical
