  • 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.)

Just an FYI from a Spectrum cable customer.

Recently, my cable modem died. I had a spare sitting around and was able to swap in the backup with only a quick call to Spectrum to give them the MAC address. Then, I went shopping for another spare modem. For speeds under 500 Mbps, there is now one and only one modem on the Spectrum list of allowed devices.

Technically, the list includes two modems, but one is so old that new units are no longer being sold. The only choice is a Netgear CM1000 whose regular price is $230. There are other allowed modems but they are all combination modem/routers.

Having a modem fail enforces the strategy of having a separate modem and router; replacing a router is a much bigger deal.
 
Wonder what prevents Spectrum from managing any DOCSIS compatible modem that you might attach to their network. I'd be keen to try using an Arris just to see if it works. :)

Agree on separation of duties 100%. Purchase of a cable modem can also offset the monthly service rental charge after a year or two.
 
If you do get the combo router/modem, it would help with the separation of networks. Use the Router on the combo device for your phones. Use the Router behind that for your PCs, set up an isolated network on the second router for IOT.

It solves some problems...
 
There are 34 devices listed in the “Approved for Spectrum Internet tiers up to 1G” category, which will obviously work on a connection under 500 Mbps as well, and I know at least 10 of them are just modems. Seems like most DOCSIS 3.1 modems are acceptable:
