1) please specify what edition you are talking about (Standard or Driver)
2) are you having any particular problems right now or your just query? In general, everything should work ok, and if there are some problems or limitations, we need to fix them.

1. I'm trying testing it with Driver Edition
2. It's a query - because I don't know or it's normall situation when I try:

1. copy my storage file to DVD-RW
2. usling simple mounter (now ver 1.0.9) try MOUNT this storage file from DVD

.... and have: System Error. Code: 5

maybe it's normall jet? that mounting in this way (on CD or DVD) storage files is not possible? - I just don't konw and ask You about it.

sorry for my inconvinience - my english is "litle" poor - but I hope You can understand me now, please ;)

best regards - mirek

I think the problem is that SimpleMounter tries to mount the storage in read/write mode, and this is not possible as the disk is read-only. You can try modifying the sample to open the storage in read-only mode.

Hi,

TXH for help - it's realy work when I set before open "Strorage.ReadOnly := True". Now I must say - Your component is beautyful !!! ;)

.... but i will tell about one problem. It shold be not often but ...

so when I mount in readonly mode - my storage file from CD, add point p:, next start some exe file from virtual drive p: - all work good but what can happend when my furthcoming customer working with my application using SolidFile system - make some mistake and press EJECT button in CD/DVD --- ooops we have in this situation mega crash - MS Blue Screen for 1-2 second max (I see in this short time some info about solfs.sys) and PC is reboting

hmmm maybe U can make some function in Yours drivers to LOCK CD/DVD when storage file on this is mounting (so eject is not possible) .... or maybe U make another way to prevent this BlueScreen and PC reboting

best regards - mirek

The problem is related to the way Windows accesses CD-ROMs (they use different sector size). Also, there are some bugs (eg. ** Assertion failed: FALSE
** Source File: D:\nt\private\ntos\io\read.c, line 295) in Windows. We have to add a workaround for the issue.
