Thank you for your help.

Sony PRS-650 Launcher
Device: /dev/sdg
Mount point: Mounted at /media/SETTING

rdh@rdh-desktop:~$ sudo fsck.vfat -y /dev/sdg
[sudo] password for rdh:
dosfsck 3.0.7, 24 Dec 2009, FAT32, LFN
open: Read-only file system

~

If, "Linux kernels mount filesystems as readonly when there are errors on them", then presumably the errors need to be corrected and to do this the filesystem first needs to be mounted as read and write.

I need to know how to change this volume's attribute and how to correct the errors.

I have looked at the Linux man page and tried to understand, but I still don't know what the correct syntax for lvchange is! Should I use the following?

lvchange -pr/w /dev/sdg

Here are some variations that I have tried, in attempt to get the syntax right:

rdh@rdh-desktop:~$ sudo lvchange -pr/w /dev/sdg
Invalid argument r/w
Error during parsing of command line.
rdh@rdh-desktop:~$ sudo lvchange -permission r/w /dev/sdg
Invalid argument ermission
Error during parsing of command line.
rdh@rdh-desktop:~$ sudo lvchange -p r/w /dev/sd
Invalid argument r/w
Error during parsing of command line.
rdh@rdh-desktop:~$ sudo lvchange -p w /dev/sd
Invalid argument w
Error during parsing of command line.
rdh@rdh-desktop:~$ sudo lvchange -pw /dev/sd
Invalid argument w
Error during parsing of command line.

I don't know what the correct syntax is! I need help.
Could someone knowledgeable of Linux help me, please?
Thanks in advance.

Addendum
I don't understand the purpose of the Sony PRS-650 Launcher volume.
Is the launcher volume common to all Sony PRS-650 readers?
My Sony PRS-650 seems to perfectly, so this problem only prevents me from using Calibre.
Was the Sony PRS-650 Launcher volume created when I installed Calibre?
Could someone who has a Sony PRS-650 and who has not used Calibre, tell me whether their reader has a launcher volume, please?
