| Post subject: | Recordings prematurely ending after freezing |
I am having an odd problem. It recently started affecting almost every recording I have that is over 1 hr long. It freezes up around the 1 hr mark and then goes back to the menu saying the recording has ended after about 30 seconds to 1 minute. If I play it again and skip over the part that had the freezing happen to it, it keeps playing from that point. Sometimes it happens again in the same recording. I am not sure what I can do to give more information on this, Here is my mythfrontend.log Code: 2008-06-29 06:28:37.318 Received a remote 'Clear Cache' request

You are getting errno=5 errors. 5 is rather a generic error number but it sounds as if you may have a hard drive that is on it's last leg. Now would be a good time to back up. I would suggest that you test your hard drive. A simple test would be to do Code: dd bs=1M if=/dev/hda of=/dev/null as root. This assumes your hard drive is /dev/hda.
You might consider installing and running smartctl (part of the smartmontools package) against that hard drive. Cliff |

Here is the output of that command. Code: dd: reading `/dev/hda': Input/output error 393+1 records in 393+1 records out 412221440 bytes (412 MB) copied, 12.9493 seconds, 31.8 MB/s How would I go about installing smartmontools? I think this may point to it going out even more.... Code: root@mythtv:/home/user# dmesg | grep hda

Yep, your hard drive is bad. The 'dd' command that you ran only read 400 meg (that's meg, not gig) of the drive before it hit an error. hda is the whole hard drive. hda1 is the root (program) partition. hda2 is the swap space. hda3 is where your recorded shows are stored. If you have important recordings on hda3 and you are willing to spend a good number of hours learning, setting up, etc. You might be able to save some of your shows. Start by determining if it is worth it by redoing that dd command on hda3 instead of hda. If it gets all the way through with no errors you might be able to rescue some recordings. I wouldn't bother with smartmon tools since we are seeing disk errors when simply reading the disk with dd. I hope you don't have anything that you want to keep on it... One thing you could try would be to unplug the hard drive cables from both ends and maybe even remove other devices that are on that cable. Plug just the hard drive back in and try again. Once chance in 10000 that this will help. Another thing to try is to make sure that the hard drive has good ventilation and is not running hot, Open the computer case and blow a desk fan on the hard drive for 15 minutes and try again with the desk fan still running. Hard drive controllers (part of the motherboard) sometimes go bad and you can't tell whether the hard drive is bad or controller is bad. You might move the hard drive to another computer, boot a Knoppix (not Knoppmyth) CD and run the dd command that way. Be aware that your hard drive will probably be something besides /dev/hda. When a controller goes bad it writes bad data on the hard drive. This data can never be read by any controller. The hard drive is still good, but it looks bad because of the bad data. Always reformat and test a bad hard drive on another computer before discarding it. To install smartmontools do this: Code: apt-get update apt-get install smartmontools Make sure you don't have anything recording while doing the smartmon tests. Do this logged in as root(reboot later to get back to MythTV): Code: init S pkill xinit /etc/init.d/mythtv-backend stop To test the drive then do this: Code: smartctl -t short /dev/hda (takes minutes to test) or this:Code: smartctl -t long /dev/hda (takes hours to test)Wait however long it told you to wait then do this to view the test results: Code: smartctl -a /dev/hda | less and look for overall pass/fail on the first page.
Warning: the following may damage the hard drive: One thing you could try only as a last effort to copy data off of a drive that you are about to discard would be putting the hard drive in the freezer for 20-30 minutes and then quickly put it back in the PC, boot up, and copy off the files you want to save. If this were my system I would: - move the hard drive to another PC - boot Knoppix CD - use dd_rescue to read the hard drive and write the same data back to it (dd_rescue -A -d -D -b 1M -B 4096 -v /dev/hda /dev/hda) if there is only one hard drive hda will probably be sda for recent versions of knoppix - test the hard drive with smartctl (smartctl is already installed) Good luck, Cliff |

I think the pvr150mce-lp does not come with a remote. It is not a digital tuner. It is also "low profile". Is your new case low profile? I've got a system (girlfriend's) with a pvr-350, but it is set up to capture video from the set top box. I would go with a bigger hard drive. The best size/$ ratio is with the 750's and 1000's now. If you are considering high def in the future, now is the time to buy things that are maybe more in that direction. On the other hand all you need is a hard drive so why a new system? I'd buy a new hard drive after testing the old hard drive in a different pc by writing the whole drive 'dd bs=1M if=/dev/zero of=/dev/bad-hard-drive-goes-here' then reading the whole drive 'dd bs=1M if=/dev/bad-hard-drive-goes-here of=/dev/null' Buy one that is compatible with both the new and old systems (SATA-II if your old system will handle it) and wait till there is more of a reason to upgrade to buy anything else.

Ok so I downloaded Knoppix and here are the results from putting it in another system. Code: root@Knoppix:/# dd bs=1M if=/dev/hda of=/dev/null

I ran the smart tests and it passed both the long and the short one. I've got nothing on there now, I watched all my recording and deleted them. I also ran backup on it so I guess now I need to get a new HD. Reason I was thinking of building a new one was this one uses an IDE HD so I won't be able to take it to a newer computer. Thanks for all the help Cliff. |

The key is to put it in another system, then write the whole drive to remove any "controller caused errors", then read the whole drive (with either dd or smartctl) to see if it really has any errors any more. ------------------- The reason dd_rescue is good to write the drive is that it can read the whole drive and write what it can read back out. You will be left with a disk that you can at least copy the files back off of. The fact that it reads and then writes the data back in the same place will cause the read errors that you see. That is normal. The key is whether the drive has any errors AFTER writing the whole drive. You seem to indicate that smartctl says there are no errors. That means the hard drive is OK. If you let dd_rescue run all the way through, I would run: Code: dd bs=1M if=/dev/hard-drive-goes-here of=/dev/null in addition to the smartctl tests and if there are no errors you can
put the hard drive back in service with an 80% chance that there is nothing wrong with it and that the problem was in the old PC. Sorry for the confusion... Cliff |

I was in a different system before. Also dd rescue takes forever.... Code: Summary for /dev/hda -> /dev/hda:
dd_rescue: (info): ipos: 245117376.0k, opos: 245117376.0k, xferd: 245117376.0k errs: 104, errxfer: 416.0k, succxfer: 245116960.0k +curr.rate: 68575kB/s, avg.rate: 12438kB/s, avg.load: 0.7% root@Knoppix:/ramdisk/home/knoppix# dd bs=1M if=/dev/hda of=/dev/null dd: reading `/dev/hda': Input/output error 932+1 records in 932+1 records out 977797120 bytes (978 MB) copied, 55.0316 seconds, 17.8 MB/s root@Knoppix:/ramdisk/home/knoppix# so is the Disk toast? |

If you put the hard drive in another PC and wrote the whole drive (dd_rescue hda hda is one way, 'dd bs=1M if=/dev/zero of=/dev/hda' is faster than dd_rescue but absolutely erases all data) and you still get errors when you read it with 'dd bs=1M if=/dev/hda of=/dev/null' after that then the disk is toast.

Something else to consider: Bad HDD ribbon cable. I've had this happen to me a few times. |
