How Long Does a Hdd Surface Read Test Typically Last

Should a "Write/Read" surface test be followed by formatting the drive?

I recently purchased Hard Disk Sentinel. I did a Write/Read surface test against an external USB backup drive. The test reported 0 errors. Only later the examination was completed, the bulldoze became unrecognizable to Windows. Sentinel support is telling me that this is normal considering all the partition data is overwritten during the Write/Read exam, and therefore one would need to reformat the disk after the Write/Read exam is completed. Is this true with all similar deejay utility tools? For case, if I use the "Erase" option in HDDScan, would I need to reformat the drive afterwards the test is completed?

Welcome to the Th community, starchess!

Depending on the HDD utility itself, these options are chosen differently. Regardless which software tool y'all determine to use, always brand sure that y'all are familiar with its features and functions. Moreover, ever make sure you do a backup of your data before attempting whatever HDD scan/diagnostics. The Write/Read examination uses different, nevertheless intensive methods to test the surface of the hd. Unfortunately, it could be subversive for your data and it usually permanently erases everything during the test operation. So yes, the support guys are right, you should be able to access the HDD once again get your arrangement to recognize it, once you re-initialize it and partition & format it from Disk Management.

As for the other HDD tool, I'd propose you to cheque the software developer'southward website. Still, after selecting the "Erase" option, it would nearly certainly require you to reformat the hard bulldoze again.

The best way to prevent any data-loss headaches would be to always have your most precious files backed up on at least ane other storage device/drive. This fashion you'd still have the data stored on the other drive, in case the primary ane fails. Besides, it's better to exist safe than pitiful, right?

Hope this was helpful. Go along me posted if yous accept farther queries.

The read portion can exist done without destroying data, but doesn't consistently observe errors.

Whether the write portion requires a format depends on whether it was a "non destructive" or "subversive" test. Non sure how the non destructive i works, just over again, it doesn't consistently find errors. The destructive 1 writes alternating 1s and 0s to every sector on the bulldoze thus overwritting everything and corrupting information technology at the same time. For this reason, it requires the bulldoze to exist reformatted once complete. This method will pick upwards pretty much whatever errors or bad sectors on the physical drive though.
