Compact Flash card problem

["Alex Kwan" <alexkwan@pacific.net.hk>]

Hi!

I am using a 64MB CF card  with a PCMCIA adapter
in my notebook, the read and write is o.k., but when
insert this card will have following error message:
hdc: SanDisk SDCFB-64, ATA DISK DRIVE
ide1 at 0x100-0x107,0x10e on irq 9
hdc: drive_cmd:status=0x51 {DriveReady Seek Complete Error}
hdc: drive_cmd:error=0x04

What is the reason and how to fix it?

Thanks!

Alex
