Hi all, I just got another empeg off ebay the other day, it was advertised as having 2 20 gig drives but it showed up in emplode as having only one 20. I started to take it apart and noticed 2 of the 4 hd tray screws were gone, I then got into it finding one 20 gig hitachi drive from a compaq laptop and a toshiba 30 gig also from a compaq in the slave position without a jumper. I prceeded to take the toshiba out and check the first drive, it seemed to work but when I uploaded some tunes I got this:
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=35178154, sector=3501
2779
end_request: I/O error, dev 03:04 (hda), sector 35012779
hda: read_intr: status=0x5b { DriveReady SeekComplete DataRequest Index Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=35178155, sector=3501
2780
end_request: I/O error, dev 03:04 (hda), sector 35012780
hda: read_intr: status=0x5b { DriveReady SeekComplete DataRequest Index Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=35194531, sector=3502
9156
end_request: I/O error, dev 03:04 (hda), sector 35029156
hda: read_intr: status=0x5b { DriveReady SeekComplete DataRequest Index Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=35194533, sector=3502
9158
end_request: I/O error, dev 03:04 (hda), sector 35029158
hda: read_intr: status=0x5b { DriveReady SeekComplete DataRequest Index Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=35194531, sector=3502
9156
end_request: I/O error, dev 03:04 (hda), sector 35029156
This was kinda long so I didn't put it all in there, I know the drive is trashed what I was wondering does emplode mark those spots as bad so it doesn't write to the again? Also I searched the bbs for the serial of this empeg and found this thread So it seems the original owner had some problems with this thing. Here is the ebay link

Yes and no. This error handling is dealt with at the disk itself. When you read from a bad block, you get an error (after a number of retries). When you write to the disk, if there's an error, the drive will remap that block to somewhere else.

So, reads: no; writes: yes, within reason. Within reason, because there's only a small number of spare blocks on the disk for this purpose.

If you want to ensure that bad blocks are marked as such on the disk, you'll need to plug it in as the second disk, with a known-good first disk. Then, using the developer image, issue the command:

dd if=/dev/zero of=/dev/hdc

...which will write zeros all over the second disk. Any sectors that cannot be written to will be remapped somewhere else. Obviously, you'll need to run the disk builder (see the FAQ), since the disk is now filled with zeroes.

OTOH, if the disk is that bad, just buy another one. 20Gb and 30Gb disks are relatively cheap and easy to get hold of.

Thanks for the reply, I am going to replace that drive anyway I was just wondering what the empeg did with bad blocks. The strange thing is the toshiba drive is good but the empeg fails to recognise it, when trying to build it I get to "selecting pump device" and then just hangs. I think I read a thread somwhere about the empeg not likeing toshiba drives.
