It\(aqs built around the workflow of dealing with +hard drive bad blocks. It has a number of features to limit risk in +using the tool and provides features to more easily track down what +files are affected by the bad blocks found. It also gives you the +ability to manually mark blocks as corrupted in cases where a block +isn\(aqt technically bad, but is causing issues. +.SH FEATURES +.INDENT 0.0 +.INDENT 3.5 +.INDENT 0.0 +.IP \(bu 2 +readonly scanning of bad blocks +.IP \(bu 2 +safe \(aqfix\(aq mode which won\(aqt overwrite good blocks +.IP \(bu 2 +burnin mode for checking new drives +.IP \(bu 2 +manual marking blocks as corrupted +.IP \(bu 2 +find files given list of blocks +.IP \(bu 2 +dump list of files and associated block ranges +.IP \(bu 2 +dump list of blocks used by a file +.IP \(bu 2 +issue secure drive erasure +.IP \(bu 2 +filesystem stressing +.UNINDENT +.UNINDENT +.UNINDENT +.SH OPTIONS +.SS Arguments +.INDENT 0.0 +.TP +.B \-f\fP,\fB \-\-force +override checking if drive is in use when trying to perform destructive actions +.UNINDENT +.INDENT 0.0 +.TP +.B \-t, \-\-rwtype \fIos|ata\fP +select between OS or ATA reads and writes (default: os) +.UNINDENT +.INDENT 0.0 +.TP +.B \-q\fP,\fB \-\-quiet +redirects stdout to /dev/null or otherwise limits output +.UNINDENT +.INDENT 0.0 +.TP +.B \-s, \-\-start\-block \fIlba\fP +block to start from (default: 0) +.TP +.B \-e, \-\-end\-block \fIlba\fP +block to stop at (default: last block) +.TP +.B \-S, \-\-stepping \fIn\fP +number of logical blocks to read at a time (default: physical / logical) +.TP +.B \-o, \-\-output \fIfile\fP +file to write bad block list to (default: $HOME/badblocks.*captcha*) +.TP +.B \-i, \-\-input \fIfile\fP +file to read bad block list from (default: $HOME/badblocks.*captcha*) +.TP +.B \-r, \-\-retries \fIcount\fP +number of retries on certain reads & writes +.TP +.B \-c, \-\-captcha \fIcaptcha\fP +needed when performing destructive operations +.TP +.B \-M, \-\-maxerrors \fIn\fP +max r/w errors before exiting (default: 1024) +.UNINDENT +.SS Instructions +.sp +\fBinfo\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a block device.

A read\-only scan of the block device for +bad blocks. \fIrwtype=ata\fP will be slower but may catch more. +.sp +Relevant options: rwtype, start block, end block, stepping, max errors, input file, output file. +.UNINDENT +.UNINDENT +.sp +\fBfix\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a block device. Writes to bad blocks in an attempt to +force the drive to reallocate the block. Attempts to read the block +first and will write the read data if successful otherwise it will +write zeros. This means it is pretty safe to use even if the blocks +\(aqfixed\(aq aren\(aqt in fact damaged. +.UNINDENT +.UNINDENT +.sp +\fIrwtype=ata\fP will work better. +.INDENT 0.0 +.INDENT 3.5 +Requires captcha. +.sp +Relevant options: captcha, rwtype, force, input file. +.UNINDENT +.UNINDENT +.sp +\fBfix\-file\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a file. Gets the list of blocks that a file uses and then +goes through each block reading what is there and then writing it +back which will force reallocation if a block is bad. +.sp +\fIrwtype=ata\fP will work better. +.sp +Requires captcha. +.sp +Relevant options: captcha, rwtype, retries. +.UNINDENT +.UNINDENT +.sp +\fBburnin\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a block device.

Spawns a number of threads to hammer the +filesystem using a number of functions to stress the filesystem and +underlying device. Functions include: create, open, mkdir, unlink, +rmdir, write, read, close, readdir, stat, chmod, chown, link, +symlink. Cleans up after itself on exit but does consume storage and +inodes as it runs. +.sp +Use \fI\-\-quiet\fP to keep it from printing out what it is doing and improve performance. +.UNINDENT +.UNINDENT +.sp +\fBfilethrash\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a non\-existent file. Creates a file, expands it to fill +up the rest of the filesystem, and spawns a thread per core which +writes 1MB blocks to the file at random offsets to stress the +filesystem and unerlying device. +.UNINDENT +.UNINDENT +.sp +\fBfind\-files\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a filesystem mount point. Attempts to find the +files associated with any blocks listed in the bad block input +file. Useful after running \fIscan\fP to find the files with bad blocks. +.sp +Relevant options: input file. +.UNINDENT +.UNINDENT +.sp +\fBdump\-files\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a filesystem. Scans the filesystem and dumps a list of the files with the blocks on the device it occupies. +.UNINDENT +.UNINDENT +.sp +\fBfile\-blocks\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is an existing file. Prints out a list of all logical blocks the file uses. +.UNINDENT +.UNINDENT +.sp +\fBwrite\-pseudo\-uncorrectable\-wl\fP +.sp +\fBwrite\-pseudo\-uncorrectable\-wol\fP +.sp +\fBwrite\-flagged\-uncorrectable\-wl\fP +.sp +\fBwrite\-flagged\-uncorrectable\-wol\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a block device. Marks blocks listed in the bad block input +file as \(aqpseudo\(aq or \(aqflagged\(aq uncorrectable. Blocks marked \(aqpseudo\(aq, +when read, cause the drive to perform normal error recovery and +return errors if necessary. Blocks marked \(aqflagged\(aq, when read, +will simply return errors indicating it is bad. \(aqwl\(aq means \(aqwith +logging\(aq and if read will result in failed reads being stored in +SMART logs. \(aqwol\(aq means \(aqwithout logging\(aq and will not log any read +failures in the SMART log. +.sp +Relevant options: input file. +.UNINDENT +.UNINDENT +.sp +\fBsecurity\-erase\fP +.INDENT 0.0 +.INDENT 3.5 +\fIpath\fP is a block device. Issues an ATA Security Erase command to +the device. What this means specifically is device specific but +generally it is supposed to be like a low\-level format. Use with +care. +.sp +Requires captcha. +.sp +Relevant options: captcha. +.UNINDENT +.UNINDENT +.sp +\fBenhanced\-security\-erase\fP +.INDENT 0.0 +.INDENT 3.5 +Theoretically a more thorough version of the standard ATA Security +Erase command.
