  • 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.)

on system 3
81 is wd blue ssd

Nice numbers, Alex!

alex1440

thanks, I wish the numbers where a little better on my wd blue drive's I hade bought them a few months ago to late to return them now will just use them to archive my files and backups
only if I knew they would hade these numbers I have gotten different drive

alex1440

my wd blue drives to be more clear have 256 MB Cache so they are not the older model of the drive some that only got around 64 to 128 in Cache

alex1440

I wish the speed where a little better not going to try and complain a lot because I hade bought them around 130 for each new
the number to those drives seem to a little over the place
I about system 1 for drives 86 and 87 that are wd blue 5400 rpm drives 256 MB Cache

heck man, nowadays I might and try and only stick the 64MB Cache wd black drives have not to hade many problems with my other 2 wd black drives

@Steve I have some
2.5-inch drive's like 5 of them or more
form old labtops
I need to look for them I will come back with some more results

No apology, Alex. The benchmark is providing interesting and possibly valuable information to its users, and in the process it's verifying the correct operation of the new hardware driver code that's finally finished and will be heading into SpinRite. So this is all good! :)

It is interesting that the performance of these drives seems to roughly follow the size, larger disks are faster. Or is it a function of the age of the drive, larger disks are newer and also faster?

Newer, larger drives typically have a higher writing density, bits per inch, so given the same rotational speed, it will read/write the data faster. If they gain the extra capacity from extra platters with the same writing density, you won't see the same speed increase.

It's both actually. Some drives do age over time, but I assume the difference is not noticeable in most cases because newer drive tend to increase the density anyway causing them to be faster than older drives when they're new. I assume that with an older drive not being able to go the speeds when new mostly had something that SSDs do with replacing bad sectors with other good sectors (I remember a spinning drive I had throwing SMART errors because it that was the reallocation value going too high. Ended up replacing with a slower drive because the company seemed to have switch completely to SSD at the point I needed the replacement)
