Another question, on my pc, the hd supports cache flushes, it shows:
[EMAIL PROTECTED] linux-2.6.20-dm]# hdparm -T /dev/hdb
/dev/hdb:
Timing cached reads: 3344 MB in 2.00 seconds = 1671.72 MB/sec
and my target board does not support cache flushed, it shows:
[EMAIL PROTECTED] tmp]# ./hdparm -T /dev/hda
/dev/hda:
Timing cached reads: 68 MB in 2.04 seconds = 33.30 MB/sec
I don't know if this feature is the inducement, I want to disable this
feature on pc, what's the command? thanks

hi,all
I want to enable cache flushes for my hd on s3c2410 & linux-2.6.20,
ide_id_has_flush_cache() return 0 because cfs_enable_2 is 0x201, while it
needs 0x3000, I found out that 0x201 was from 512 bytes of id
info,implemented in static void ata_input_data(ide_drive_t *drive, void
*buffer, u32 wcount)
the question is, does it mean my hd does not support cache flush on hw
layer? if not, how to enable?
thanks for the coming help!
