07:01 < jonoh> hi again, i posted here yesterday but had to leave. I am trying to install rockbox on my classic 6g but it gets stuck on the "formatting" page. Any Help?
07:08 < [Saint]> in theory if this stage stalls it should be possible to format it as a fat32 superfloppy manually
07:09 < [Saint]> Oh, hmm. Possibly not.
07:09 < [Saint]> I did see your post yesterday but I have no idea why this would be happening.
07:10 < [Saint]> Does the iPod function correctly in the original firmware, I assume so, yes?
07:11 < jonoh> yes it does. tried reformatting to fat using windows
07:13 < jonoh> when i boot the installer, i get an errror message "ATA: Error 8000000 while reading BBT" (not sure if thats the exact number)
07:13 < jonoh> but it is only there for a microsecond, then it goes to the "emcore installer"
07:14 < [Saint]> You would really want to talk to [7] about this.
07:14 < [Saint]> WHich may mean having to idle for some time.
07:15 < jonoh> ok. would it be easier to use the mailing list? or just wait here
07:16 < [Saint]> it would probably be easier to idle here.
07:16 < [Saint]> user890104 may be able to help you as well.
07:16 < [Saint]> They both will have been highlighted now, so its just a matter of time.
07:17 < jonoh> cool. thanks
07:39 < user890104> jonoh: smells like bad hard disk to me
07:40 < jonoh> yeah thats what i thought. I ran chkdsk on windows, and it gave no errors
07:40 < jonoh> is there a way to modify the code to ignore the error?
07:41 < user890104> well this error basicly means "we can't access your hard disk, there's some issue"
07:41 < user890104> the BBT (bad block table) is the first thing our firmware attempts to read
07:42 < user890104> so in your case, the hard disk is inaccessible, and any subsequent attempts to access it would also fail
07:42 < user890104> your best bet is to wait for [7]
07:42 < user890104> he might have an idea, but keep in mind that these devices are pretty fragile
07:43 < user890104> we also had a case, where a brand-new ipod classic had a bunch of bad sectors
07:43 < [Saint]> doesn't the installer use a badblocks file if its present?
07:44 < user890104> it does, but it needs to access the HDD first
07:44 < user890104> and if that fails, you see that error
07:44 < [Saint]> AH, right. Derp.
07:44 < user890104> so this doesn't mean "we can't access some sector, because it's damaged"
07:45 < user890104> it means "we can't access the hard disk at all"
07:45 < user890104> but anyway, wait for [7]
07:46 < user890104> what we suggest in these cases, is to replace the ipod in an apple store (if the warranty period hasn't expired)
07:46 < user890104> they usually check the hard disk, and replace the device if it's faulty
08:00 < jonoh> sorry, just doing something else. its a very old one, and i have already replaced the drive myself once. 
08:09 < user890104> jonoh: i see. can you reboot it (menu+select), then immediately hold center+left, until you enter diagnostics mode?
08:14 < jonoh> yep
08:15 < jonoh> should i do manual or auto?
08:20 < user890104> manual
08:21 < user890104> go to IO - HardDrive - HDSmartData
08:21 < user890104> and tell me the numbers ()retracts, reallocs, etc.
08:23 < jonoh> retracts:5, reallocs: 0, pending secotrs:0, powerOn hours 892, startstops: 18484
08:25 < user890104> oh, that looks pretty well
08:25 < user890104> almost like a new one
08:26 < user890104> ok, scratch the bad hdd option, and wait for [7]
08:26 < jonoh> i did just do a deep format. would that have reset it?
08:26 < jonoh> okay. :)
08:26 < user890104> how did you format it?
08:26 < jonoh> in windows disk manager, and unticked quick format
08:27 < user890104> emcore formats it at a lower level (it repartitions it and erases apple's hidden firmware partition)
08:27 < jonoh> oh ok.
08:27 < jonoh> i'll keep waiting
08:27 < user890104> another case would be failing to access the last sectors of the hdd
08:28 < user890104> i don't know where the BBT is stored, but if it's at the end of the hard disk, there are some bugs with some hard disk firmwares
08:29 < user890104> you're either hitting one of these, or the sector where bbt should be stored, is somehow damaged
08:29 < user890104> so yes, please keep waiting here
08:29 < user890104> [7] is in GMT+1 time zone, and he usually appears online at the evening/night
08:46 < jonoh> ok. i'm in gmt +10

09:33 < [7]> jonoh: you said you replaced the HDD manually... with which type of HDD?
09:33 < [7]> and what's the exact error code? (focus on the last digits)
09:33 < [7]> user890104: BBT is sector 0
09:34 < [7]> if that one would be broken, the device couldn't even be partitioned
09:34 < jonoh> ummm. it was a few years ago, i think it was the same as the ones that are meant to be in there. ie a toshiba (i think) 160gb
09:34 < jonoh> let me have a look
09:34 < [7]> thick or thin model?
09:35 < jonoh> thick. it was the first classic (6g)
09:35 < [7]> so that's the CE-ATA beast
09:38 < jonoh> i think it was sector 0, count 1
09:40 < [7]> I mean that "error 80000XXX" code
09:40 < [7]> that one provides some technical info on what did actually go wrong
09:41 < jonoh> oh, its just 8 followed by all zeros
09:43 < jonoh> also, when i run the bootstrapper program to get the umsboot partition, i get an error "deviceiocontrol error", but it still works. Is this a problem
09:44 < [7]> that message is to be expected
09:45 < jonoh> ok.
09:45 < jonoh> yep. definately 80000000
09:47 < [7]> wtf
09:47 < [7]> that error seems to mean that this assertion failed: (sector + count <= ata_total_sectors)
09:48 < [7]> given the values from your error message, this means that ata_total_sectors must be 0
09:48 < jonoh> ok. that is wierd
09:49 < [7]> that in turn means that the relevant fields in the IDENTIFY response of the drive are zero
09:50 < [7]> ...or that code not even getting reached
09:51 < [7]> I just spotted a missing error check that could make it reach that point if ata_power_up failed
09:52 < [7]> the error code reported by it doesn't get shown anywhere :/
09:52 < [7]> so it could be any one of these that's failing: mmc_init, ceata_init or ata_identify
09:54 < [7]> hm, this doesn't really help
09:54 < [7]> might be some timeout being too tight or something like that
09:54 < [7]> I've seen these CE-ATA drives take up to 10 seconds before responding after powerup
09:57 < jonoh> ok. so is there a way to increase this? I am looking at the source code, but i must admit my c skills are not that great
10:26 < [7]> walk through ata_power_on and its subroutines (always assume that ceata is true)
10:28 < [7]> hm, looks like this is already factored out properly
10:28 < [7]> http://websvn.freemyipod.org/filedetails.php?repname=freemyipod&path=%2Femcore%2Ftrunk%2Ftarget%2Fipodclassic%2Fstorage_ata.c
10:28 < [7]> these lines:
10:28 < [7]> #define CEATA_POWERUP_TIMEOUT 30000000
10:28 < [7]> #define CEATA_COMMAND_TIMEOUT 1000000
10:28 < [7]> #define CEATA_DAT_NONBUSY_TIMEOUT 5000000
10:28 < [7]> those values seem to be plenty though
10:28 < [7]> (those are microseconds)
10:29 < [Saint]> There's definitely some issue, I think I remember telling you it never sounds like the disk is being shut down properly.
10:30 < [Saint]> the ce-ata disk always sounds nasty when its powered down by either emcore or Rockbox.
10:30 < [Saint]> but with the of its nice and quiet.
10:31 < [7]> [Saint]: that sounds like the sleep(1000000); in ata_power_down should be increased
10:31 < [7]> it really shouldn't take more than a second for that drive to park its heads, but apparently it does
10:31 < [Saint]> where is the equivalent in Rockbox hiding?
10:31 < [Saint]> I'm not set up to build emcore.
10:31 < [7]> or the 0xe0 command above is being ignored by the drive
10:32 < [7]> http://git.rockbox.org/?p=rockbox.git;a=blob;f=firmware/target/arm/s5l8702/ipod6g/storage_ata-ipod6g.c;h=395c0f49e646199a3d16bbb5f63c33be2643c1e3;hb=refs/heads/master#l680
10:32 < [7]> bump that to 2*HZ or something
10:33 < [Saint]> thanks, I'll try in an hour or so.
10:47 < jonoh> thanks for looking into it guys. I really am out of my depth here
