What to do About a "U" (Unrecovered) Indicator

  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

  • 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.

The "Graphic Status Display" window shows one "U" (Unrecovered) marker. Does this mean that Spinrite automatically replaced that sector or group of sectors with good, readable sector(s), or do I need to do something to fix this problem with the drive? The "S.M.A.R.T. System Monitor" window shows a "raw data" figure of "11" for "uncorrectable" and "0138" for "write errors".
 
The U should mean that the data was lost, but not that the sector is unusable. If the sector is unusable, it would be marked 'B'. There is a command line option (by user request, including my own) that will prevent SpinRite from "clearing" an unrecoverable LBA, in the case you wanted to try a different utility with it, but this is off by default, and you'd need to specify it to have that happen.

You could double check me by running SpinRite again (do a partial pass maybe) (use SHIFT ENTER to specify start and stop sector or start and stop percentage, or use the command line.) The U shouldn't show on a second pass.

TL;DR: There is nothing further to do but to be aware you potentially lost some data.
