HD IDE: EXT2-fs error



Dear Sirs,

We are experiencing some problems using Hard Disk IDE with Etrax100LX.
We developed a test application that writes data on HD (up to 500KB/sec) and
we noticed that when the amount of data stored on the HD reaches about 7-8
GBytes, application can't store further data: the kernel print the following
messages
    EXT2-fs error (device ide0(3,1)): ext2_new_block: Free blocks count
corrupted for block group 1024
while the application print the following
    fwrite: No space left on device
We notices a couple of the above kernel message (with different group
blocks) during the storing of the first 7 GByte, but the application goes on
storing data; When the messages refer to block group 1024 the application
never recovers and the kernel continually prints the same message (every
time the application try to store data)
If we delete some data from the HD, the application starts storing again,
until the amount of data stored on the HD reaches again about 7-8 GBytes.

The HD have the same behaviour even storing data using ftp: we obtain a
"Free blocks count corrupted for block group" 1024 or 1025.

We obtained the "Free blocks count" error every time we tryed to store more
that 8GBytes. Moreover, during some of the test performed, we noticed the
following messages

1)
EXT2-fs error (device ide0(3,2)): ext2_new_block: Allocating block in system
zone - block = 3858633

2)
EXT2-fs error (device ide0(3,2)): ext2_free_blocks: Freeing blocks in system
zones - Block = 3907726, count = 1

3)
EXT2-fs error (device ide0(3,2)): ext2_free_blocks: bit already cleared for
block 3841422

4)
03:01: rw=1, want=904593410, limit=10490413
attempt to access beyond end of device

We created partitions and formatted the HD using "Partition Magic"
(selecting primary ext2 partition).
Is there any known issue regarding "Etrax & formatting HD" ?

Hardware configuration:
    We have added the ATA/IDE interface to a board similar to Developer
Board LX (but with 32MB SDRAM).
Sofware configuration:
    kernel 2.4.19 (we had to fix a small bug on ide driver)
    Axis Developer Board LX release 2.1.0
HD used:
    Seagate "Barracuda" 40 GBytes
    Seagate "Momentus" 40 Gbytes


Thanks
Regards
