  • 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.

    (You may permanently close this reminder with the 'X' in the upper right.)

I am currently in an RV, returning home after viewing the solar eclipse in Little Rock, Arkansas. It's a 2-month trip overall. I rely on my laptop for managing digital photos, but neglected to bring my copy of SpinRite with me. Of course, my Windows laptop "died" about 10 days ago - it would not boot at all. Windows Chkdsk got it running again, but it was horribly slow and virtually unusable. Then I listened to Steve's recent Security Now description of his woes with an SSD on Laurie's machine, and I realized I was experiencing the same problem. So I dug through some old emails (vintage 2008!) to find my SpinRite product key, purchased a new USB thumb drive (forgot to bring a spare!), downloaded and installed SpinRite, and set it working last night. This morning, SR reported that it had processed Level 3 on both SSDs. I rebooted the machine, ran the Disk Maintenance as recommended by SR, and the computer seems back to its old self. That's the first time in the 16 years since I purchased SR that it's come through for me. Thank you for a great product, Steve.

BTW - the detailed statistics at the end of the run showed that the primary SSD took 5:40 h to run, while the secondary SSD required 2:14. Both are nominally 1 TB. The primary SSD reported that it had 69,136 "Total writes" and 64 "Realloc space". The secondary SSD reported zeros for both of these statistics. Neither disk reported any errors. Am I correct in assuming those stats are symptomatic of the "weak or slow read" problem that Steve described on Security Now?
 
Congratulations on the successful recovery of your SSD's original performance. (y) Calling the "raw" SMART data that various SSDs choose to publish “unreliable” would be kind. You can see this in the fact that your two SSDs are showing very different data for those two metrics. There is other information that SSDs tend to publish that's more useful, things like total reads and total writes over the life time of the device. But these can also be SSD-specific (like that "Total Writes" reading.)

The bottom line is that the most universally useful metrics are the SMART health parameters since those are designed to show "relative health" of each parameter as determined by each device. SpinRite v7.0 will push this information gathering further and will also have a UI that allows for device logs to be displayed and interpreted, which are a newer addition to more recent drives.
