HDDScan

HDDScan is a freeware software for hard drive diagnostics (RAID arrays servers, Flash USB and SSD drives are also supported). The program can test storage device for errors (Bad-blocks and bad sectors), show S.M.A.R.T. attributes and change some HDD parameters such as AAM, APM, etc...

HDDScan can be useful for performing the regular "health test" for your drive and predicting its degradation, so you will be able to prevent data loss and backup your files before you would have to contact the data recovery service.
Additionally, software can be used as the hard disk temperature monitor and reading/writing benchmark – performance graph is displayed for every test.

Features:

Supported storage devices:
IDE (ATA) and SATA HDD.
SCSI (SAS) HDD.
External USB drives and all major USB boxes.
FireWire or IEEE 1394 HDD.
RAID volumes made of ATA (IDE) / SATA / SCSI HDDs (surface tests only).
USB Flash (pen drives) – surface tests only.
SATA / ATA SSD – solid state drives.

Storage device tests:
Verification in linear mode – fastest way to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.
Reading in linear mode – same as verification but also transfers data to the host.
Erasing in linear mode.
Reading in Butterfly mode (synthetic random read).

S.M.A.R.T.:
Reading and analyzing SMART parameters from ATA/SATA/USB/FireWire HDD.
Reading and analyzing Log Pages from SCSI HDD.
SMART tests running on ATA/SATA/USB/FireWire HDD.
Temperature monitor for ATA/SATA/USB/FireWire/SCSI HDD.

Additional features:
Reading and analyzing identity information from ATA/SATA/USB/FireWire/SCSI HDD.
Changing AAM, APM, PM parameters on ATA/SATA/USB/FireWire HDD.
Reporting defect information on SCSI HDD.
Spindle start/stop function on ATA/SATA/USB/FireWire/SCSI HDD.
Reports can be saved in MHT format.
Reports can be printed.
Command line support.
SSD SMART and Identity reports.
