Uhm.. it seems like I spoke too soon!
I have now acquired a Sandisk Extreme III 8GB CF card, from a
reputable source, but it doesn't support UDMA as the Extreme IV card
was supposed to... and this means I'm getting MWDMA again - and the
same timeout problems!
I had previously blamed the timeout problems on it being a completely
naff card which wasn't standards compliant, but now I know this can't
be the case.
Here is the hdparm:
/dev/sda:
CompactFlash ATA device, with removable media
Model Number: SanDisk SDCFX3-8192
Serial Number: 019324G2207I5851
Firmware Revision: HDX 4.03
Standards:
Supported: 4
Likely used: 4
Configuration:
Logical max current
cylinders 15880 15880
heads 16 16
sectors/track 63 63
--
CHS current addressable sectors: 16007040
LBA user addressable sectors: 16007040
device size with M = 1024*1024: 7815 MBytes
device size with M = 1000*1000: 8195 MBytes (8 GB)
Capabilities:
LBA, IORDY(may be)(cannot be disabled)
Standby timer values: spec'd by Vendor
R/W multiple sector transfer: Max = 4 Current = 0
DMA: mdma0 mdma1 *mdma2
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns
Commands/features:
Enabled Supported:
Write cache
* CFA feature set
* CFA advanced modes: pio5 *pio6
Note that it does identify PIO5 and PIO6 (answering my previous
question), with PIO6 even starred. I got about 9MB/s under hdparm,
too.
However, the timeouts remain, I triggered it again by doing a mkfs.ext3.
Any ideas?
Thanks,
Eddie
