Changing Drive Attribute ReadOnly-> Full Access->Bum

NOTE 2006-03-31: SOLVED - NOT A SALAMANDER ISSUE

Hi, using Salamder 2.5 Beta 11 and changing the drive attributes from readonly to full access (if you don't have a SAN, same problem with USB sticks occur):

* Salamander does not recognize that he can now write, copy or move
* Salamander closes without any message

Not really a great problem (may occur seldom) but not very convenient for me...

Could you be more specific, please?
Describe how to reproduce your problem step by step.
Specify your Windows version.

Hello,

OS: Windows XP SP2 and Windows XP Professional SP2

Easiest way to reproduce (with USB stick):
* set USB stick to read only
* stick it in
* start salamander
* go to a directory on the usb stick
* try to move a file to your harddrive
* message "read only"
* switch USB stick to read-write (leave it in your pc, stay with salamander on the USB directory)
* salamander immediately exits

This also happen with an storage area network: displaying a directory on an read-only drive with salamander, changing the drive attributes to read-write and salamander immediately exits.

Hey, this is really not important, switching to another dir, changing drive attributes and then come back - everything is fine.

Could you reproduce this problem from another computer? Or with another USB stick?

I suppose the Servant Salamander is not installed on your USB stick / SAN drive?

We are not able to test this issue because we have not access to USB stick with read-only switch.

Btw, how do you set the USB stick to read-only mode? Using some hardware switch? Or some additional drivers?

My friend just brought me USB stick with read-only switch.
No problem here on Windows 2000 Pro SP4 EN and Windows XP Pro SP2 EN.

Hello,

* Salamander ist NOT installed on the USB stick (that would explain everything)
* the problem occurs on around, hm, difficult to count, 100PC

I'll check it with another USB stick ...

Ok, seems to be a problem of filesystem on the USB stick:

If it contains an ext2 filesystem then the problem occurs, for any combination of NTFS and FAT32 (I tested some) there is no problem.

Then I tested the behavior on changing drive attributes of the SAN and Salamander only has the problem IF THE USB STICK IS STICKED IN (sorry, I did not mentioned that, normally the USB stick is in if I work on a PC).

Finally I converted my ext2 partition to ntfs - and the problem disappeared: For the USB stick and for the SAN!

Looks weird to me, I did not mount the ext2...

IT'S DEFINETILY NOT A PROBLEM OF SALAMANDER!

Thanks a lot for your help. Great product, great service!

Thank you for detailed information!

How do you access the EXT2 filesystem from Windows? Do you have some drivers installed?
It would be nice if we could test this problem. Servant Salamander should not crash (quietly)...

You mention the point I did not understand: The ext2 partition on the usb stick was never mounted, no driver was installed, it had no drive assigned and did not show up either in "My Computer" nor in any drive list of any programm...

You could only see it in the drive management (Datenträgerverwaltung) of the system administration (Computerverwaltung).

I really do not understand what was happening there.

Nevertheless there's another hidden partition on nearly every system at my work, it contains the system backup data. It makes - as far as I can proove it now - no problems. And at home there's a hidden truecrypt encryptet partition which also makes no problem.

As far as I can observe this, it's the ext2 fs under windows.

-> It looks like you have access to your USB stick.

I don't understand. Is it a different USB stick?
Or more partitions on one USB stick (I have no idea if this is possible)?

Oh, yes, three partitions on one USB stick:

1st was 1 GByte NTFS - normally mounted
2nd was 128 MBytes FAT32 - normally mounted
3rd was 768 MBytes ext2 - not mounted, no drive assigend, no driver loaded
4th was 128 MBytes truecrypt hidden volume, sometimes mounted through trucrypt
