kernel: FAT: bogus logical sector size

[CaféMartin]

Hi All!

I'm happily running the WL-500g for allmost a year now.
Now I'm trying to run an ftp-server on an external USB/Firewire hdd-casing (mycom), with a WD1600JB hdd. I have installed Oleg's 1.9.2.7-2 firmware.

When making a 32GB FAT32 partition with windows xp it works like a charm.
When making a 160GB FAT32 partition with partition magic the disk is mounted as read-only, due to problems with the sector size.

These are 2 fragments of the log:

01:00:01 kernel: FAT: bogus logical sector size 3840
Jan 1 01:00:01 kernel: FAT: bogus logical sector size 3840
Jan 1 01:00:01 kernel: NTFS: Unable to set blocksize 512.
Jan 1 01:00:01 kernel: VFS: Mounted root (squashfs filesystem) readonly.

1 01:00:16 kernel: VFS: Can't find ext3 filesystem on dev sd(8,1).
Jan 1 01:00:16 kernel: MSDOS FS: Using codepage 950
Jan 1 01:00:16 kernel: MSDOS FS: IO charset cp950
Jan 1 01:00:16 USB storage: vfat fs mounted to /tmp/harddisk
Jan 1 01:00:18 FTP server: daemon is started

Elsewhere in the forum I read that this partition can succesfully be created and mounted, using the same program. I'm not very familiar with linux, the things I find with google were no keys to a solution.

I've checked the clusters with partition magic, that seemed to be ok.
I've formatted the drive again, mounted it succesfully (read-write).
Then I loaded the disk with data, allmost full, mounted it again and got the same bogus sector size issue again. I'm not sure "NTFS: Unable to set blocksize 512" is indicative, since there's no ntfs-partition on the drive.

Who can give me a hand with this one?

/edit:

This problem seems to be caused when one mounts the external usb harddrive under xp. I did this to fill the disk with data. xp adds system files and directories (system volume information and recycler), besides system restore data (which I had allready turned off for that drive).
It's solved by restarting xp in safe mode and simply deleting these files and directories.
I mounted the drive under the router again and everything worked fine again. So the "NTFS: Unable to set blocksize 512" is indicative.

I initially had problems formatting my drive to 160Gb as well. The solution for me was to connect the harddisk to an IDE port on my pc and use a DOS diskette with Ranish Partition Magic to partition and format the disk.
