建议谁做一个集成的U盘启动维护工具包安装程序(把非启动的U盘,MP3做成超强启动盘,用10M足够把所有的经典DOS工具装进去了)
,在U盘,MP3上安装它时会把它们做成超强启动维护盘(只占10M),并把把维护系统的工具全放在U盘里,人们一般要装点资料,很可能就随时放在身上的,一遇到谁的电脑崩了,拿出来就用,力挽狂澜. 那才叫爽!..
不过,也可以自己做,也可以作成超强启动盘
(比如,在DOS下,加载了USB驱动后,都是把U盘当成硬盘的.改写U盘的主引导和分区表,使它能启动,(好象U盘的MBR只有一个扇区,不是真硬盘的63个,整整一个磁道).在WINDOWS下方便一点,用WINHEX,或ULTRAEDIT,把启动型U盘的启动代码改写MBR(好象是33 C9处,前面的跳转代码也要看一下)和DBR,把分区表的第一区改成活跃分区80,再改写DBR,或着能不能DOS下用SYS改写DBR?这个我没试过)
我已经把我的MP3弄成了启动盘,但还没试呢? 嘿嘿...
软盘非常容易坏,和光盘一样携带不方便..
我的U盘就是启动型的,并且放了大部分超强工具.还放了我的硬盘的 MBR DBR FAT表,和各个盘的DBR,基本上不用担心进不去系统的,即使不用工具,用手输入硬盘数据都是可以修复的.
有一次,我有意改了分区表和系统引导扇区的值,结果它偏偏就是不坏,气死我也!
有几次进不了了,再改回原来的值,又正常了,有时耍一耍硬盘,还是挺有意思的.
还有一次,为了测试各大维护软件的优劣,我清零了我硬盘的MBR DBR
那些瑞星修复,金山修复,大名鼎鼎的ndd,diskgen(diskman),easyrecovery,dm,pq,尽是臭态百出.
不是无能为力就是帮倒忙! 那个diskgen扫到一半,死机了. ndd 扫了半天,修复后,把我的FAT表全搞乱了.害的我启动XP后,警告文件全乱了! 用GHOST 恢复后再次清零...
再试KV3000,一秒钟修复! (后来发现,可能KV3000用第7扇区的原有DBR的备份恢复系统的)
而其他工具全然不知...
狂晕....
It is suggested that someone make an integrated U disk boot maintenance tool kit installer (to make non-bootable U disks and MP3 players into super powerful boot disks, and it is enough to use 10M to install all classic DOS tools in it). When installing it on a U disk or MP3 player, it will make them into super powerful boot maintenance disks (occupying only 10M), and put all the tools for maintaining the system in the U disk. People generally need to store some data, and it is very likely to be carried with them at any time. As soon as someone's computer crashes, they can take it out and use it to turn the situation around. That would be really cool!..
However, it can also be made by oneself, and it can also be made into a super powerful boot disk. (For example, under DOS, after loading the USB driver, the U disk is treated as a hard disk. Rewrite the master boot record and partition table of the U disk to make it bootable. (It seems that the MBR of the U disk has only one sector, not 63 sectors like a real hard disk, which is exactly one track). It is more convenient under WINDOWS. Use WINHEX or ULTRAEDIT to rewrite the boot code of the bootable U disk's MBR (it seems at 33 C9, and the jump code in front also needs to be checked) and DBR. Change the first partition in the partition table to active partition 80, and rewrite the DBR. Or can the DBR be rewritten using SYS under DOS? I haven't tried this.)
I have made my MP3 into a boot disk, but I haven't tested it yet. Hehe...
Floppy disks are very easy to be damaged, and are as inconvenient to carry as CDs.
My U disk is a bootable one, and most super powerful tools are placed in it. I have also placed the MBR, DBR, FAT table of my hard disk, and the DBRs of each disk. Basically, there is no need to worry about not being able to enter the system. Even without using tools, it is possible to repair by inputting hard disk data manually.
Once, I deliberately changed the values of the partition table and the system boot sector, and it just didn't break down. It really annoyed me!
There were times when I couldn't enter, and then changed back to the original values, and it was normal again. Sometimes playing with the hard disk is quite interesting.
Another time, in order to test the advantages and disadvantages of major maintenance software, I cleared the MBR and DBR of my hard disk.
Those瑞星 repairs, Kingsoft repairs, the famous ndd, diskgen (diskman), easyrecovery, dm, pq, all made a bad show.
Either they were powerless or made things worse! The diskgen got stuck halfway through scanning. ndd scanned for a long time, and after repairing, it messed up my FAT table completely. It made the warning files all messed up after I booted into XP! I restored it with GHOST and cleared it again...
Then I tried KV3000, and it repaired it in one second! (Later I found that maybe KV3000 restored the system using the backup of the original DBR in the 7th sector.)
But other tools didn't know anything...
Crazy...
