Is PSI okay? I used XUSEN to map my NTFS formatted primary partition C: to H: but the partition number is not 1, but comes later, which causes a problem!

Hehe, made a mistake, know what it's for now

I don't know what it's for either, you tell us the result of the experiment!

What is it for? How to use it?

Recently, I have sorted out the boot disk, but after burning it, I found several problems in the actual machine.

1. For motherboards that support SATA, it is very easy for the PSI to analyze the hard disk information incorrectly. This is quite sad. I wonder if modifying the batch processing can improve this problem?

2. During the actual machine operation, DIRT also started to make mistakes (normal in the virtual machine). First, the last two lines of the search result are ERROR: CAN NOT GET COMMAND.COM'S PSP. Secondly, the modified search batch processing of XUSEN is directly interrupted and exited due to DIRT. Again, it is found that the search batch processing using DIRT sometimes gets stuck and dies on a certain drive letter.

In conclusion, I feel quite depressed.

1. Motherboards supporting SATA often cause PSI to analyze hard disk information incorrectly. I haven't encountered this. I tested that SATA hard disks are normal, but NTFS compressed partitions have serious errors! (SATA optical drives were not tested)
2. DIRT works normally. Mine was written by myself and didn't fully refer to XUSEN's search engine! DIRT searches the NT partitions of SATA hard disks at normal speed, but there is a problem of time delay when searching the NT partitions of old hard disks. If SMARTDRV is loaded, searching the NT partition sometimes crashes! Overall, it's still acceptable!

Then for judging the partition problem of the USB flash drive, it can be solved as follows:
When the drive letter is not switched in the AUTOEXEC command, use cd> to judge whether it is the C drive!
I don't know if it is feasible or not?

Hey, I also hope it's not a DIRT issue. I'll test tomorrow whether it's a problem with the boot disk IO, SYS, or COMMAND.COM, or maybe an issue after GRUB is loaded.

Searching the first-level directory should be faster. By habit, GHO files are generally also in the first-level directory. Why is a search taking so long?

1. It is necessary to judge whether it is a full-disk search or a single-partition search!
2. It is not only to search the first-level directory, but to truly conduct an all-round search!
3. It is necessary to know the results and sort them!
Hehe, I have streamlined this many times and made many changes!

Then why not try lmod to separate the part after X:\ at one time? Isn't that also convenient? And then processing with WBAT is also good?

Finally, after several more days of work, I finally achieved something! Both XUSEN's and my original ones took 30-50 seconds to boot into the system. Today I added a small command, and now it takes 10-13 seconds to boot into the system, and the search is extremely fast! Hehe, it's really a miracle!

The slow speed is mainly consumed on PSI. As long as you use PSI to analyze hard disk information, it won't be fast. Unless you replace it. I also gave up the old version of the search batch processing of XUSEN. After removing the useless display of search percentage, the search speed is very fast.

I added a cache driver QCACHE.SYS and the speed became extremely fast (never use SMARTDRV, because DIRT will die!)

14 seconds to boot:

DEVICE=\SYS\MEM\HIMEM.SYS /TESTMEM:OFF
DEVICEHIGH=\SYS\MEM\EMM386.exe noems
DEVICEHIGH=\SYS\MEM\QSCACHE.SYS /F /S7



9 seconds to boot:

DEVICE=\SYS\MEM\HIMEM.SYS /TESTMEM:OFF
DEVICE=\SYS\MEM\UMBPCI.SYS /S
DEVICEHIGH=\SYS\MEM\QCACHE.SYS /L /S5
