This is true, but EIDE and SATA drives use Logical Block Addressing -- the on-drive circuitry remaps requests to actual blocks on disk. It is normal in such drives that the drive itself detects and remaps bad blocks, and drives reserve some spare capacity for such remapping. This means that the OS should never see any bad blocks at all. The drive should remap and hide them. So, if any appear, it's because the drive has so many bad blocks that all the reserve capacity has been exhausted. This almost always means that the drive has severe physical damage to the medium, and as such, is probably on the brink of failure. Summary: if you format a drive and it reports any bad blocks at all, don't use it. Replace it immediately. If it's new, get a warranty replacement; if it's old, discard it. -- Liam Proven • Profile: http://lproven.livejournal.com/profile Email: lpro...@cix.co.uk • GMail/G+/Twitter/Flickr/Facebook: lproven MSN: lpro...@hotmail.com • Skype/AIM/Yahoo/LinkedIn: liamproven Cell/Mobiles: +44 7939-087884 (UK) • +420 702 829 053 (ČR) -- Lubuntu-users mailing list Lubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/lubuntu-users
