Of run the manufacturer's reformatting utility which reformats the disk (back up first - the disk will contain no data after the reformatting). But even those two steps didn't fix one of my drives - I noticed that both utilities had problems when they were about 98% done with the sector scan. So I resized my partition to avoid the last 2% of the disk and have had no problems since then. For https://coderanch.com/t/610924/gc/fix-bad-sectors-hard-disk a laptop, my recommendation is to get another hard drive and use a drive imaging tool to move you existing data to the new drive. Then place the old drive into a USB enclosure and run the tools on that at your leisure. If the old drive is still usable you'll have a convenient backup drive.

Does low level formatting fix bad sectors? Paul Clapham Sheriff Posts: 21443 33 I like... posted 3 years ago It isn't necessarily possible to fix a bad sector -- for example if there's a scratch on the surface of the disk, that can't be fixed. Especially by software. However the formatting process is supposed to recognize bad sectors and exclude them from the file system. So essentially as far as the operating system is concerned, once that's done they don't exist.

Low level format, also known as "zero fill drive" writes a 0 to each and every memory location down to byte level. This will only safely erase all your data, without being able t
and only cause some noise in your syslog. In most cases the disk will automatically reallocate one or two damaged sectors and you should start planning http://www.sj-vs.net/forcing-a-hard-disk-to-reallocate-bad-sectors/ on buying a new disk while your data is safe. However, sometimes the disk won't automatically reallocate these sectors and you'll have to do that manually yourself. Luckily, this doesn't include any rocket science. A few days ago, one of my disks reported some problems in my syslog while rebuilding a RAID5-array: Jan 29 18:19:54 dragon kernel: [66774.973049] end_request: I/O error, dev sdb, sector 1261069669 Jan 29 hard drive 18:19:54 dragon kernel: [66774.973054] raid5:md3: read error not correctable (sector 405431640 on sdb6).

However, a sector only gets relocated when a write operation fails. A failing read operation will, in most cases, only throw an I/O error. In the unlikely event a second read does succeed, some disks perform a auto-reallocation and data is preserved. In my case, the second read failed miserably ("Unrecovered read error - auto reallocate failed"). The read errors were caused by a sync of a new RAID5 array, which was initially running in degraded mode (on /dev/sdb and /dev/sdc, with /dev/sdd missing). Obviously, mdadm kicked sdb out of the already degraded RAID5-array, leaving nothing but sdc. That's not something to be very happy about… The only solution to this problem, was to force sdb to dynamically relocate the damaged sectors. That way, mdadm wouldn't encounter the
