Can any write a folder create and verify program ?

[exxos]

In light of me diagnosing corrupted file entries etc here viewtopic.php?p=103887#p103887

Could anyone just write me a program which say creates 100 folder in C: root, then writes 100 folders in each of those folders for 10,000 folders total (maybe more folders would help but cant remember per directory limits , if any?)

Then have a loop which reads all the folder names and verifies they are all correct. Outputs error somehow, either change screen red or just stop and output error found.

Currently it only seems to error on deleting files, but I don't think deleting files is the problem, I think its reading the FAT incorrectly causing bad folder names.

Oddly doesn't seem to ever error on actual files. so not sure it is needed to actually write any files or verify them. It could have a secondary verification test which may be ultimately useful to others as well. Maybe write a known number sequence to files in each folder created and verify contents. But at this time I dont think its needed.

Currently I'm having to sit all day watching it delete endless thousands of folders manually and just not a constructive use of time

I asked ChatGPT but no idea if it's correct Assume not.

Code: Select all

START   equ $4000
SYSBASE equ $4
DOSBASE equ $4BA
FO_CREATE equ $5A
FO_DELETE equ $5C
FO_OPEN   equ $58
FO_CLOSE  equ $5E
FO_READ   equ $62
DNAMELEN  equ 64
FSIZE     equ 16
DFL_MODE  equ $1FF

        lea     start(PC),a0
        movea.l a0,a6

        movea.l sysbase,a6
        move.l  dosbase,a1

create_loop:
        moveq   #0,d0
        lea     filename(PC),a2
        moveq   #DOS,A3

        move.l  a1,(a6)
        jsr     fo_create(a6)
        move.l  d0,d1

        tst.l   d1
        bne.s   error

        move.l  d0,a0
        movea.l #FO_OPEN,a1
        jsr     (a1)

        move.l  d0,d1
        moveq   #0,d0
        tst.l   d1
        bne.s   error

        move.l  d0,a0
        movea.l #FO_CLOSE,a1
        jsr     (a1)

        movea.l a1,a0
        movea.l #FO_DELETE,a1
        jsr     (a1)

        move.l  d0,d1
        moveq   #0,d0
        tst.l   d1
        bne.s   error

        dbra    d7,create_loop

end_loop:
        move.l  d7,d0
        move.l  d7,d1
        sub.l   d6,d0
        move.l  a1,a0
        jsr     fo_read(a6)
        move.l  d0,d1
        moveq   #0,d0
        cmp.l   d1,d0
        bne.s   error

error:
        nop
        stop    #$2700
        nop

filename:    dc.b    'testdir',0
start:       nop

If no one does it sooner I'll knock something up next weekend when I get back

Here you go...
Directory count is an issue - I had to add FLDRXXX.PRG to AUTO for it to work. Without it, getting out of memory errors. e.g FLDR999.PRG

Test prompts for drive letter to create directories - defaults to C:
Test then prompts for number of directories to create - defaults to 100 - max of 999

Directory creation starts - <drive letter:>/DIRTEST/DIRWRxxx where xxx is an incremented number
If directory creation fails - an error is printed and the test aborts

If all directories are created, then the test goes on to delete them all. If a directory is not found ie. a write error occurred and trashed the name, then an error is printed

At the end of the test you should examine <drive letter:>/DIRTEST - it should be empty

It takes around 40 minutes to create and erase 999 directories on my STe with 4MB and TOS 2.06

NOTE - I've only tried this with HDDriver 512MB TOS/WIN partitions

Hope this does what you want

Nice one thanks. Will try when I get back home.

Does it verify folder names as creating and deleting alone generally isn't enough . That's the odd thing, that invalid folder names are still deleted like it read the correct name but displayed a corrupted one. I've not seen anything left on the drive during all my tests. It's very odd.

[dad664npc]

Yes it verifies directory names. If a corrupted directory exists then it will not be deleted - a message will be printed to say the expected directory does not exist and it will abort the test, so all directories after the failed one will remain

So I took out the mods I did on my STE blitter. First run or the program created a few folders then crashed, though this is actually to be expected under the specific conditions I am looking for.

Now it is just a matter of leaving it on and see how long it takes until it fails again. Its on its 3rd 999 folder pass. So I think really it should have failed again by now. I will fill up the SD Card and again and make sure it does those fine again next. Likely will continue in my blog as not to cross threads to much.
