Test and repair in a completely different environment

If a hard disk is intended to be used as an external USB disk or internal disk, I prefer to re-initialize it when it's connected as an external USB disk or internal disk respectively. I understand it's better to test and repair a hard disk in a proven environment, but "test and repair in a comp...

Re: BIOS int 13h: WRITE test vs WRITE + READ test

When burning CD/DVD, there's verify option; if it's not verified, there's a possibility that the media is not burnt correctly. When copying files, there's verify option; if it's not verified, there's a possibility that the files are not copied correctly. The low level disk write, like hdparm --write...

Re: New feature: re-initialize in place???

Like chkdsk, windows full format probably works at partition/volume level, and never fixes bad sectors. Re-initializing a 4TB drive seems to take about 391 hours. I wish windows full format could be a simple version of re-initialize.

Re: BIOS int 13h: WRITE test vs WRITE + READ test

Thank you very much for confirming that no license will be wasted as long as it's on the same computer. I understand now that WRITE test doesn't use any disk cache. The following statement has been intriguing me. WRITE test - Overwrites the disk surface with configurable pattern. Forces the analysis...

Re: New feature: re-initialize in place???

The simple version of this test is usually (incorrectly) called as low level format by other tools.
Is windows "full format" also a simple version of "Reinitialize disk surface"? Full format seems to take less time.

Re: BIOS int 13h: WRITE test vs WRITE + READ test

Thank you very much for the detailed explanation. If I understand you correctly, the write process doesn't guarantee the data is written to the disc media, and as long as the write process doesn't report any error, it is deemed the data is written successfully. Understanding low level details can ma...

BIOS int 13h: WRITE test vs WRITE + READ test

I've been trying to understand WRITE test vs WRITE + READ test. On the surface these two tests are kind of similar. "WRITE test - Overwrites the disk surface with configurable pattern. Forces the analysis of any weak sectors and verifies any hidden problems and fixes them by reallocation of bad...

Re: Surface Test > Pause, Assume

I didn't know the side effect of those actions. Seems the right click also pauses the test.

Thank you very much for the prompt solution.

Surface Test > Pause, Assume

Surface Test might take more than 24 hours. WRITE + READ test is WRITE all/specific blocks + READ all/specific blocks in stead of (WRITE + READ) each block of all/specific blocks, for good reasons. A workaround is to specify first and last blocks each time, but it's not very convenient. It would be ...

What does "Save Disk Information" do?

What does Surface Test > Save Disk Information do? Does it save the test configuration / status with the disk? Thank you.
