  • 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.

Not sure if this is covered elsewhere. If so, I apologize.

I ran 6.1 on a ‘factory recertified’ seagate xos 20TB drive. After completion, every status screen was clean except this one. Is something I should be concerned about? I am pretty sure the drive is fine. I would like to just be sure before adding the drive to my NAS.
 
If you tried to attach an image, it didn't work. The file size limit on this forum is 500 kB. The log file would also be useful. It is in the SRLOGS folder on your SpinRite boot drive. It generally works best to put them in a ZIP archive before uploading.
 
@firefighter25120 shared a SpinRite 6.1 LOG, a few lines pulled out here:

First, update your SpinRite 6.1 Release 2, it's up to Release 4 by now, see https://www.grc.com/upgrade.htm

Second, being familiar with Seagate, those ECC and seek numbers are normal for Seagate, see https://forums.grc.com/threads/how-...n-this-in-progress-log-from-a-new-drive.1560/ here in the GRC Forums, and elsewhere across the web.

Third, I prefer cooler running than 106°F, and so I'd put a supplemental cooling fan directly cooling the drive, and I aim for 88°F or less, peaking only occasionally under constant use at 99°F.

Fourth, check, clean, and preserve the contacts between the circuit card and the drive body, especially considering the drive's age, I've returned refurbished Seagates that looked like the left picture below. Regardless, I periodically check and make sure that all my drives look like the right picture below.

The drive is fine. Seagate uses ECC Corrected (and other attributes) for something else entirely that is proprietary to Seagate. It is thus "normal" for Seagate drives to show high numbers here. The drive is fine. You had a green screen saver at the end of the run, right? :)
 
Thank you for sharing the log file. I agree with the others that those SMART numbers look perfectly normal for a Seagate drive.
