 Posted: Fri Jan 12, 2007 2:50 pm Post subject: USB memory missing and other inconsistencies |
 |
|
I have Cowon U3 audio player that mounts as a regular usb storage device to transfer musics and other files. I'm having some problems with the memory reporting.
(1) When I delete files the memory isn't being freed. When I thought the player was full I deleted a 25 MB file but amarok said there was only 5.5 MB free.
(2) When I navigate on the player to check free memory it says there is 256 MB free
I think dmesg is reporting some (probably) relevant errors but I don't know how to interpret them.

Sounds like | Quote: | | sdc: unknown partition table |
| Code: | | cd /usr/src/linux make menuconfig |
check your filesystem type and compare with those in your kernel config.
Try to recompile kernel with some more enabled. Also may be some other usb support needed look under device drivers >> usb>>.
Hope that helps

Thanks.
The filesystem is FAT32 and I have support enabled. I reformated the drive with fdisk and now I don't get the "unknown partition table". I'm guessing there was something fishy with the FAT32 filesystem that came installed on the device.
All works fine now. |
