Transfer mode not working?

[alexey123]

I use CF card connected to IDE slot as system disk for working NAS4Free server.

# dmesg | grep ada0
ada0 at ata0 bus 0 scbus0 target 0 lun 0
ada0: <SILICON POWER 20110927> ATA-7 device
ada0: 100.000MB/s transfers (UDMA5, PIO 512bytes)
ada0: 3831MB (7847280 512 byte sectors: 16H 63S/T 7785C)

My system

NAS4Free 9.1.0.1 (revision 804) x86-embedded
KM400 AWRDACPI AMD Sempron(tm) 2200+ 992MiB RAM

bus=1 hubaddr=1 port=0 devaddr=2 interface=0 bus=1 hubaddr=1 port=0 devaddr=2 interface=1 Generic IEEE 802.3u media interface VIA VT6202 USB 2.0 controller VIA 83C572 USB controller PLIP network interface VIA 8235 UDMA133 controller RTL8169S/8110S/8211 1000BASE-T media interface

But, transfer speed on tab Disks|Management|Disk|Edit not limit transfer speed.

I need limit my transfer speed, because this is compact flash
Write test

If I read this correctly, I do not know how to limit your CF card transfer speed.

[raulfg3]

Use a 40 pin old flat IDE cable to limit transfer speed.
Use short cable that You have.

I not use cable, I use direct connected adapter such as


Power supply repaired by July, motherboard capasitors replaced by March.. I replace full version to embedded, because full version was freeze.
Currently: sometimes I have message such in this post, from new CF card.
Sometimes = one week without messages, yesterday I receive more then 100 times, today without mesages

Code: Select all

(ada0:ata0:0:0:0): READ_DMA. ACB: c8 00 5f ba 01 40 00 00 00 00 20 00
(ada0:ata0:0:0:0): CAM status: Command timeout
(ada0:ata0:0:0:0): Retrying command

Such messages I received from old 2.5 inch disks.

I think such behavior because CF card not have ram buffer, as hard disk, it need reduce speed.

I find solution. If I add to loader.conf (loader.conf.local) string

Code: Select all

hw.ata.ata_dma=0

I swich CF to PIO4 mode.
If I define

Code: Select all

hw.ata.ata_dma=1

swich it to UDMA 5 mode
Result

$ dmesg | grep ada0
ada0 at ata0 bus 0 scbus0 target 0 lun 0
ada0: <SILICON POWER 20110927> ATA-7 device
ada0: 16.700MB/s transfers (PIO4, PIO 512bytes)
ada0: 3831MB (7847280 512 byte sectors: 16H 63S/T 7785C)
ada0: Previously was known as ad0
GEOM: ada0s1: media size does not match label.

Hmmm, transfer mode over webgui realy not work

[alexey123]

FreeBSD 9.2 - removed last chance reduce IDE Speed!
hw.ata.ata_dma - not working

How about moving to a spare usb stick (of course this is not internal then) ?

How about moving to a spare usb stick (of course this is not internal then) ?

Not good idea for my HP D530. It have usb1 during boot stage, ~15 minutes for boot.

@ alexey123

try 40pin IDE Flash Module --> http://uk.transcend-info.com/industry/p ... &Func1No=1

few Years ago i used CF to IDE Adapter, too & ran into some problems from time to time

no more problems after switching to IDE 40pin Flash Module

[apollo567]

try 40pin IDE Flash Module --> http://uk.transcend-info.com/industry/p ... &Func1No=1

Thought about this one also, but decided then for a Pico-USB stick. Might be an good idea.
How about a USB 2.0 extention card (check Hardware compatibility of the chipset!) ?

I wan't pay any cent!!!
I add to /cf/boot/device.hints value (for my config) :

Code: Select all

hint.ata.1.dev0.mode="PIO4"

And have result ( on FreeBSD )

ada0 at ata1 bus 0 scbus1 target 0 lun 0
ada0: <Hitachi HDS721680PLAT80 P21OA85A> ATA-7 device
ada0: 16.700MB/s transfers (PIO4, PIO 8192bytes)

I go to check NAS4Free - It work
Before

$ dmesg | grep ada0
ada0 at ata1 bus 0 scbus1 target 0 lun 0
ada0: <Hitachi HDS721680PLAT80 P21OA85A> ATA-7 device
ada0: 133.000MB/s transfers (UDMA6, PIO 8192bytes)
ada0: 78533MB (160836480 512 byte sectors: 16H 63S/T 16383C)
ada0: Previously was known as ad2

After

$ dmesg | grep ada0
ada0 at ata1 bus 0 scbus1 target 0 lun 0
ada0: <Hitachi HDS721680PLAT80 P21OA85A> ATA-7 device
ada0: 16.700MB/s transfers (PIO4, PIO 8192bytes)
ada0: 78533MB (160836480 512 byte sectors: 16H 63S/T 16383C)
ada0: Previously was known as ad2

How to check CF ( or old 2.5 inch disk) , connected to IDE:

Code: Select all

camcontrol identify adaN

Check supported modes, for my tested disk :

PIO supported PIO4
DMA supported WDMA2 UDMA6

And find adress for ata device

Code: Select all

dmesg | grep adaN

Look result
adaN at ataX bus 0 scbus1 target Y lun 0
And compose device hint

hint.ata.X.devY.mode="<supported mode>"

Supported mode is mode, when CF or ide disk not make faults
