diskscan - Scan disk for bad or near failure sectors and performs disk diagnostics
- Description:
DiskScan is a Unix/Linux tool to scan a block device and check if
there are unreadable sectors, in addition it uses read latency
times as an assessment for a near failure as sectors that are
problematic to read usually entail many retries. This can be used to
assess the state of the disk and maybe decide on a replacement in
advance to its imminent failure. The disk self test may or may not
pick up on such clues depending on the disk vendor decision making
logic.
In essence badblocks looks for fatal issues already happening and
diskscan is for upcoming issues that can be fixed.
Also, badblocks is essentially obsolete in this day and age since the
disks themselves will reallocate the data and there is no real need
to map the bad blocks in the filesystem level anymore.
