I added the following line to my /etc/conf.d/hdparm: all_args="-d1" Then I added hdparm to the default runlevel: rc-update -a hdparm default When the computer boots it sets using_dma to on for most drives. I have four drives and hda, hdb & hdd all have their flags set to on but, for some reason, hdparm doesn't also set the using_dma flag to on for hdc. However, if I manually run /etc/init.d/hdparm restart after that the flag gets set. Even starnger, sometimes, the flag still doesn't get set even after I restart the script so I added disc2_args="-d1" to conf.d/hdparm. This doesn't make the first problem disappear but at least now I know that restarting /etc/init.d/hdparm will _always_ set the using_dma flag. hdparm -i /dev/hdc /dev/hdc: Model=WDC WD1200JB-00FUA0, FwRev=15.05R15, SerialNo=WD-WCAES1128071 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq } RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74 BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=off CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=234441648 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: device does not report version: * signifies the current active mode The other drive that shares the ide channel with this one is the boot drive (hdd) hdparm -i /dev/hdd /dev/hdd: Model=Maxtor 6Y120L0, FwRev=YAR41BW0, SerialNo=Y31KM69E Config={ Fixed } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=off CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=240121728 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: (null): * signifies the current active mode Could the udma6 udma5 supported modes difference be the cause of this?

Another strange thing that I noticed today (don't know if this happened before). It seems that sometimes, for some unknown reason, after I restart the hdparm init script to enable using_dma, it gets set off. I have a directory containing some big files (>300 MB). If, after I restart the hdparm script, I run cksfv or ed2k_hash (maybe this happens with other checksum utilities and programs but I have only tested with those) the using_dma flag gets set off during the time the program computes the hashes. I don't think this is cksfv or ed2k_hash related... I think it also happened when I copied a few files and deleted them afterwards. Also, if I set the using_dma flag manually with hdparm -d1 /dev/hdc it seems this doesn't happen anymore; at least I haven't been able to reproduce the bug if I did this. Steps to reproduce: 1. /etc/init.d/hdparm restart to enable using_dma on /dev/hdc 2. cksfv * in a directory with a few large files (it seems to happen more often with cksfv than with ed2k_hash) 3. hdparm /dev/hdc will show using_dma = 0 (off)

I am seeing the same sort of behavior. Here is the output from hdparm -i /dev/hda on my system: /dev/hda: Model=WDC WD1200JB-75CRA0, FwRev=16.06V16, SerialNo=WD-WMA8C2176126 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq } RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=40 BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=234375000 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: device does not report version: * signifies the current active mode
what about hdparm-5.8?
I have tried version 5.8 and I'm still having problems. As I said in my first post, I have 4 hdds. I also have a cd-rom drive which I swap for hdc when I need to use it. I'm currently using the cd-rom drive for hdc, not the hdd like in the first post. I have left only all_args="-d1" in my /etc/conf.d/hdparm. When the computer first boots up I get the following: * Starting hdparm... [ ok ] * Running hdparm on /dev/discs/disc2/disc... * Running hdparm on /dev/hdc... * Running hdparm on /dev/discs/disc1/disc... * Running hdparm on /dev/discs/disc0/disc... * Running hdparm on /dev/cdroms/cdrom0... Which is a little strange.. why does the cdrom appear twice? Then: cloud root # hdparm /dev/hdc /dev/hdc: IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument If I run /etc/init.d/hdparm restart the using_dma is set to 1 for a short period of time, but then it resets to 0. However, if I run "hdparm -d1 /dev/hdc" manually, the flag "sticks" to 1.
> I'm currently using the cd-rom drive for hdc, not the hdd like in the first post. I'm currently using the cd-rom drive for hdc, not the hard-disk (not hdd as in /dev/hdd) like in the first post.
ok, it seems to be a gentoo-specific problem then
Yes, I think it's a problem with the init scripts, in my case at least.
Tavin: maybe you have an idea, it's your init script at last ;)
Hm, this part causes trouble for me (not sure if it is related) # check that the block device really exists # by opening it for reading if [ -b $device ] && ( : <$device ) 2>/dev/null then eval args=\${`basename $device`_args} do_hdparm fi the "( : <$device )" test will fail if there is no disk in the cd-rom. Example: # device=/dev/hdd; if [ -b $device ] && ( : <$device ) 2>/dev/null; then echo YES; else echo NO; fi NO # hdparm -I $device /dev/hdd: ATAPI CD-ROM, with removable media Model Number: _NEC DVD_RW ND-3540A Serial Number: Firmware Revision: 1.01 Standards: Likely used CD-ROM ATAPI-1 Configuration: DRQ response: 3ms. Packet size: 12 bytes Capabilities: LBA, IORDY(cannot be disabled) DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Why not replace the current broken test with "if hdparm -I $device >/dev/null 2>&1"? It makes more sense, since if "hdparm -I" fails, it is useless to try anything else.
Just to give you guys an update on this... A while ago the behaviour of the init script changed. It now correctly sets -d1 on boot. However, after a while it gets set to off and I have to manually set it to on. This doesn't last forever though, and after a while I have to manually set -d1 again. I usually do this 1-3 times a day. This only happens for hdc.
I spoke too soon... -d1 gets set correctly only 90% of the time. The other 10%, -d1 doesn't get set and I have to set it manually immediately after boot. I'm using hdparm 5.9 btw
Created attachment 66421 [details] /etc/init.d/hdparm.diff how about keeping it simple and just eliminating the attempt to open the device? diff attached.
Philip, I'm afraid that didn't solve the problem for me. I should also mention that I get an error when hdparm tries to set the settings for hdc (the disc with the problem; this is the only disc which refuses to accept -d1 from the init script so I'm beginning to think the problem doesn't lie with the init script but somewhere else): HDIO_SET_MULTCOUNT failed: Device or resource busy I also have -m16 added to conf.d/hdparm so that's the reason... however, I should mention that when I set -d1 manually (hdparm -d1 /dev/hdc) -m16 also gets set automatically even though it's not present on the command line.
ok, i filed bug #103202 which has to do with the specific problem with the init script that i observe and which i see was mentioned above in this bug.
*** Bug 103202 has been marked as a duplicate of this bug. ***
bug #103202 is not a duplicate of this one. i posted a very specific problem with the init script for hdparm.
*** This bug has been marked as a duplicate of 104683 ***
This bug is not a duplicate of bug #104683 ... This was not, originally, about CD/DVD drives (even though they were brought into discussion) but about HDD drives (I have four). Besides, I have already tried hdparm-6.3 and the problem is still there: "-d1" gets set correctly by the init script for all drives except hdc for which I manually have to set it. Please tell me what information you require as I don't know what information I should be providing.
run the latest version with debugging turned on edit the start() func and put 'set -x' at the top of it then post the output as an attachment
