MS-DOS 7.10 and LOCK command to enable/disable direct IO access to disks

[MIRKOSOFT]

Hi!

I have longer time installed MS-DOS 7.10 and at installation I enabled drive locking.
I found software which requires direct disk access and I don't know how to unlock drives.

I tried:
- remove LOCK command calling from AUTOEXEC.BAT
- use command UNLOCK <drive>

Nothing helped.
Is possible to disable drive locking for enabling direct disk access?
Or even toggle enable/disable direct disk access?

Thank you for each help.

You are using the drive letter and the colon? As in unlock C:      ?

Do you get any error messages?

[MIRKOSOFT]

Yes, drive letter and colon.

No any message.
If I write not correct value it reports:Unlock not successful.

How do you know the drive is actually locked?

@patio: Yes.

@Mirkosoft: have you any deleted files in the undelete queue?

undelete /list

undelete /purge

unlock L: (where L is your drive letter)

Note: I do not have an Win95/98 MS-DOS volume to try this on.

Look here, go down the page to the UNLOCK command notes

Salmon he's usin FAT 32...it states there the procedure only works per FAT 16

Just noticed that may only apply to recovery...

it sounds like you got the functionality backwards. LOCK allows direct disk access. UNLOCK disallows it, as seen by LOCK /? and UNLOCK /?.

Remember that most DOS applications are not designed to work with FAT32,  using those applications with a FAT32 drive will cause problems.

He also insists on usin DOS 7.1 thru all these headaches instead of finding and purchasing DOS 6.22...

Just sayin.

[MIRKOSOFT]

Used application is designed for MS-DOS and Windows 3x - Windows 95...

So I think it can work with FAT32.
