Understanding SpinRite Drive Processing Levels

  • SpinRite v6.1 Release #3
    Guest:
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Hi All,


I ran spinrite 6.1 for the first time last night, on a WD 1TB drive.

Please can someone please explain the following, about drive processing levels?

Level 2 - 3 hour processing time

Level 3 - 14 hour processing time

Level 4 - 24 hour processing time

Level - 29 hour processing time

With the drive been a terabyte in size and larger drives on the market what level would be advised for a damaged drive?

Please note that this drive is 100% healthy.

Also how is S.M.A.R.T monitor, enabled on the drive as it was disabled during the process.

Please see attached screenshots.

Thanks :)

If the drive is damaged and you're hoping to recover data from damaged sectors, start with level 2. Level 1 is a read only pass, and will not attempt data recovery. Level 2 is level 1 as long as the drive is functioning correctly, but if it encounters a damaged sector, it will attempt multiple reads to see if recovery is possible. I recommend this level for recovery because it is the least stressful option for the drive. Once you recover whatever you can, you can then use the higher levels to cause the drive to rewrite itself. Levels 3, 4 and 5 do progressively more rewriting, thus the reasons why they take longer and longer.

I agree with Paul. For Hard Drive recovery, Level 2 is what you want. Level 3 preforms a rewrite of everything that SpinRite has read and recovered. That can be useful when a drive requires “refreshing” — this can be useful for “spinners” but many people are discovering that it's amazingly useful for recovering an SSD's original performance.

Beyond that, Level 4 performs an additional final reread of what Level 3 wrote and Level 5 first rewrites the original data "inverted", rereads it to verify that, then re-inverts it back to its original state, writes and rereads it. Level 5 is useful for really “wringing out” a drive and for testing a spinning drive's surface for any defective storage regions.

In general, I'd recommend Level 2 for “data recovery” either spinners or SSDs and Level 3 for recovering SSD original performance.
 
Also how is S.M.A.R.T monitor, enabled on the drive as it was disabled during the process.
I'm confused about this sentence. Are you asking "How does SpinRite monitor SMART"? Also, are you saying that SMART stopped working during one of the scans?

Please see attached screenshots.
Your screenshots did not show up. I believe the maximum file size on this forum is around 500 kB.
 
Thanks for the detailed explanations.

@ColbyBouma I was referring to the default SpinRite message about S.M.A.R.T monitor not displaying any details but it was still functioning.

I was unable to upload screenshots due to file size.

Would it be wise then to run Level 5 on NAS drives before putting them into play?

Yes. If you have multiple drives, then I recommend also running the benchmark and comparing the drives to each other. If there's a large difference, that could be a sign of an issue. You can enable automatic benchmarking in SprinRite's settings.

Also, be prepared to wait. Level 5 can easily take multiple days on large drives.
