Venix 80286! I did not think any of that was around any more. How are you trying to mount the disk? If you are trying to use a disk created by a different OS I would not expect it to work.

I would make a backup of the disk on Venix usings a utilitiy avaiable on both platforms. I would check the specks on tar or cpio. Then resort the backup to the new system.

Hope that was some help.

Re: Can't mount hdd with Venix 80286 file system

Dear Ken.

I'm not understand that you say.
I'm try mount HDD with unix file system on different unix file system.
I do it by standard procedures of mount for different file system (it is clear from parts of log-files from my previouse message).
By unintelligible reason it procedure not complete successfully.

If somebody have solution how do it please inform me.

Re: Can't mount hdd with Venix 80286 file system

Efim,
There is no "unix filesystem". Even in linux world you can see that one linux cannot read filesystem from another linux - for example, RH linux cannot work with reiserfs, which is default fs in SUSE (AFAIK).
Linux kernel supports some non-linux filesystems - like [v]fat, ntfs (more or less), some fs from Unixware and others.

Re: Can't mount hdd with Venix 80286 file system

From what I've been able to discover, current versions of mount and fstab don't have definitions for your file system. If you were to use fdisk, then it would be a type 40 filesystem.

From what I've read here -- http://www.computing.net/linux/wwwboard/forum/28453.html -- you might try mounting as a Xenix fs.
