Показать описание
Check Hard Drive Health, Error, Bad Sectors.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 devices for errors (Bad-blocks and bad sectors), show S.M.A.R.T. attributes, and change some HDD parameters such as AAM, APM, etc.

DDS 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.

Supported storage devices:
IDE (ATA) and SATA HDD.
SCSI (SAS) HDD.
External USB drives and all major USB boxes (see Appendix A).
FireWire or IEEE 1394 HDD (see Appendix A).
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 – helps to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.
Reading in linear mode – simpler, but faster disk check.
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.
Skins support.
Command-line support.
SSD SMART and Identity reports.

How about removing the annoying music and instead actually explaining what the various different scans do and what to look out for?

If only this video had a competent narrator, instead of the world's worst B-movie music.
