random "cannot eject the volume <drive name>" error

[mulax]

i have an annoying problem, being rather a newbie to linux.
a message box ("Cannot eject the volume <drive name>") randomly pops up(drive name is always the same.). it might be helpful to know my drives configuration to solve this:
i'm running a dual boot system (windows/debian).
fdisk -l output:

under windows, i named hda1 "WINDOWS". so this seems to be the starting point of the problem. it makes no difference if i mounted the volume or not. this drive is an ATA drive, don't know if this is important to know.

i google'd the phrase "cannot eject the volume" but it seems that no one is out there having exactly my problem. any suggestions?

thanks in advance.

You found amything by typing dmesg in terminal?

Post the contents of /etc/fstab file here.

okay, thanks for your replies.
dmesg output:

[   70.682318] hdb: status error: error=0x00 { }
[   70.682321] ide: failed opcode was: unknown
[   70.682325] hdb: drive not ready for command
[   70.682370] hdb: status error: status=0x59 { DriveReady SeekComplete DataRequest Error }

and this a hundrets or thousand times. but i don't know what it means if you need the whole output, pm me please.

/etc/fstab:

# /etc/fstab: static file system information.

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda2       /               ext3    errors=remount-ro 0       1
/dev/sda5       none            swap    sw              0       0
/dev/hdb        /media/cdrom0   udf,iso9660 user,noauto     0       0

another possibly helpful information: the ATA harddisk is on the same ide port (don't know how to say in english) as the cdrom drive. but both are working fine. except for this annoying error message.

regards, mulax
