  • Larger Font Styles
    Guest:

    Just a quick heads-up that I've implemented larger font variants of our forum's light and dark page styles. You can select the style of your choice by scrolling to the footer of any page here. This might be more comfortable (it is for me) for those with high-resolution displays where the standard fonts, while permitting a lot of text to fit on the screen, might be uncomfortably small.

I just ran ReadSpeed on a Dell Inspiron 3650 with a 1TB Toshiba DT01ACA100 HD

The results are:

Code:
Driv Size  Drive Identity     Location:    0      25%     50%     75%     100
---- ----- ---------------------------- ------- ------- ------- ------- -------
 81  1.0TB TOSHIBA DT01ACA100              7.7     3.2  FAILURE    5.5     7.0

I would like to run SpinRite 6.0 level 2 on this drive, but I see a warning regarding:

Code:
Part 1 MBR followed by EFI

Code:
Invalid partition for Drive Size

This partition exceeds the size of this drive as defined by the system's BIOS or BIOS extensions.

You should NOT PROCEED to use SpinRite on this drive until you have verified and corrected the disparity between this drive and the BIOS's or BIOS extensions's understanding of the drive size.


How would I go about doing this? Or am I just stuck waiting for SR 6.1? :-/

I am a Linux system admin by day and have several bootable "rescue" media options available.

EDIT: Sorry. I did not realize RS000.TXT would be on the USB and contain the results.

SpinRite 6 doesn't know about GPT. I presume this drive has a GPT partition on it. SpinRite 6.1 will understand GPT. If you're extra brave you can backup the partition table, then blank it, run SpinRite on what will then appear to be a "raw" drive, and then restore the partition table. This is fraught with danger of course, so not to be attempted by the faint of heart.

Additionally, for yourself, and others in the future, please do NOT edit the ReadSpeed results when posting, it's much easier to respond to questions if everyone uses the same formatting.

Thanks for the suggestion.

Right now I have Clonezilla running to backup the data to an external USB drive. It seems to be working but is moving really slowly.

I thought I'd overwrite the disk with 0's or maybe DBaN and re-run ReadSpeed. 🤔

Clonezilla completed, saving each of the 5 partitions.

I used `shred -z -n0 -v` on each GPT partition (sda[1-5]), then restored the images that Clonezilla saved.

Rerunning ReadSpeed with no FAILURE this time and better numbers (attached), but I think this HD is dying.

I don't know how anyone can manage to use a Win10 system with only 4GB RAM. 😩

Code:
Driv Size  Drive Identity     Location:    0      25%     50%     75%     100
---- ----- ---------------------------- ------- ------- ------- ------- -------
 81  1.0TB TOSHIBA DT01ACA100             18.1    10.0    25.4   114.0    12.9

Suggestion: wipe the entire drive (not just the partitions), run SpinRite on it, then restore the image.

What the heck would that achieve?
It would achieve what is described, hopefully. Spinrite would probably be more comprehensive in fewer steps without destruction of data (and potential recovery).

Edit: Why did I answer that?
