I have a RCA MP3 player that is formatted as Large Floppy Fat32.  Unfortunately, it also uses a non-standard 2048 bps instead of the standard 512.  Danin512.flt allows it to be read seen but if I then partition it under eCS then Windows can no longer handle it due to the bps conversion.  Fat16 large floppy can be handled via mo640 and then eCS and Windows can both read it and the MP3 player starts (which it didn't when Windows couldn't read it) but then it didn't see any of the files I put on it.  On this device the partitioned media I don't think is an issue as it can handle a 2Gb microSD card that I have partitioned with FAT32 and eCS and Windows and the MP3 player are all happy with it.

Login at ecomstation.com and download the updates. The catch is you need a Login which you can only get by Registering your copy of eComStation.

OK, another 'this thread' related question... how to upgrade LVM ???  Just unpacking and replacing existing one isn't the way.   ???

I have problems with my new USB flash stick. I have studied this old topic to see if I could find a solution - I can't. But may be anyone of you can.
I have bought a SanDisk Cruzer Slice 8GB memory stick. I also have 512 MB SanDisk Cruzer Micro. The last one works perfect both in Windows and eCS. The 8 GB works perfect in Windows.
Neither Advanced LVM or Installation LVM really sees any of the sticks. They can see the size of the micro, but not that it is FAT-formated. They also report  them having corrupt partition tables. I can't format them in eCS.
Both USB Dock and USB Resource Manager sees the sticks and for the mini with a nice picture in USB Dock.
Trying DFSee doesn't help. DFSee use LVM to identify the disks and when LVM can't DFSee can't. I tried to use DFSee in Wind., but coudln't install it.
I managed to format it under GPARTED (Unix) with a singel partition less then 2 GB and LVM could see it, but that is no solution for me.
The stick is identified as disk 2. If I reboot the system and the 8 GB stick is connected, the reboot process halts with a message: Disk 2 not ready. Press a key.

So. What can I do? Just use the 2 GB or by me a new (not SanDisk)?

You may have use of this page:

My troubles with SanDisks have been the program they add to it - I think it's called U3. I can't exactly remember how I delt with it, but I think the U3 program has an "uninstall" feature which is reachable from windows. When uninstalled I think I couldf ormat the USB as I wished and use it as a normal one.

Hi eilygre

Not really surprised that you get problems at boot if the 8Gb drive is attached - it does not have a drive letter because it is not a Volume.

Maybe a read through "USB Removables Care and Feeding FAQs" available in the USBcfg help - http://hobbes.nmsu.edu/h-search.php?key=usbcfg&pushbutton=Search - or http://www.os2voice.org/VNL/past_issues/VNL0606H/feature_2.html will be of help.

To use the 8Gb drive with eCS it needs to be made into a Volume using LVM (you could use DFSee) while drives of 2Gb or less that are formatted FAT should simply work; they get the next available drive letter on attaching.

As LVM reports both drives as having corrupt partition tables I would guess that is where the problem lies.

You could use DFSee to delete existing partition tables and then recreate partitions - and create a Volume for the 8Gb drive. You can also use DFSee to FAT32 format the 8Gb drive if you need to use the drive on Windows as well as eCS.

Thank you.
I will read through this stuff. But just some comment now The message "Disk 2 not ready" is displayed BEFORE I have decided what OS to start. And DFSee do not "see" the memory stick and therefore don't let me do anything with it.

QuoteThe message "Disk 2 not ready" is displayed BEFORE I have decided what OS to start.

This is a BIOS problem. I see it on one of my systems (Asus M3A78-EM, with quad core AMD Phenom processor). It seems to be caused by the BIOS attempting to see if there is boot code on the disk, and not finding something that it understands.

There are two ways to avoid that:
1) Make sure the device is powered off, or not attached when booting.
2) Disable legacy USB support in the BIOS.

NOTE: If you disable the legacy USB support, you will not be able to boot a USB device that does have proper boot code on it (until you enable legacy support again). You will also not be able to use a USB keyboard until the USB drivers get loaded. That means that you will be unable to select which system to boot when Boot Manager offers the choices. A PS/2 keyboard is not affected, and it will be used for Boot Manager. USB works fine, after the drivers load.
