Bad block errors in event system log
Hello,
I am trying to find articles, shortcuts or definitive answers to some of these questions. A lot of times I see something a long the lines of this in the System log in Event Viewer.
\device\harddisk0\DR4 has a bad block. Harddisk0 can be other numbers and DR can have other numbers.
I have used a similar method outlined in this article: http://superuser.com/questions/600525/what-is-the-trailing-d-in-windows-event-log-disk-error-details to hunt down these errors. From the research I have done and just some personal experiences, I feel like there is a lot of guessing or there are not definitive answers such as, "that is drive x" or "that was my flash drive"
I do not know if there is a command that I can run that would show me the direct mapping to windows drive / partition and I feel like using winobj, wmic etc is a cumbersome process for each computer I have to maintain. Does anyone know of a shortcut?
Additionally, from research, it appears that the DRx value refers to removable drives, but I never found a definitive resource on this. Does anyone know of anything?
Lastly, I presume that harddisk0 is the first detected drive in the system. I.E. if I open up device manager, harddisk0 maps to \device\harddisk0.
is there any command that can say \device\harddisk0 is drive model XYZ with Serial XYZ?
Any direction or help is appreciated. Certainly appreciate articles or definite documentation.
If I need to clarify anything, please ask.

i have had a case where it was not the disk, but a bios error, and an update cured it.
maybe look if you have any bios updates, and see what they address (in my case, system stability)

I had to look that one up. I did see an IBM BIOS update reference fixing a bad block detection error. That is definitely worth checking out and making a recommendation for my clients, However, I am still looking for answers to my other questions, so I don't want to consider this resolved right now.
Thanks for that answer nobus, I learned something new.

run winobj from sysinternals, it helps to identify it :

Properties of the disk in device manager should give model nad serial number, if not it's in HKEY_LOCAL_MACHINE\HARDWAR

I have never had good success with the registry method. I am wondering if it is a lot of systems I use has a Raid drive. If I understand right, it sounds like there is no shortcut method to this? Can anyone confirm for sure that DR? is for removable drives?
there is confusion, caused by different numbering systems.
binary counts from DR0, logic from DR1.
software can count partitions, and drives

Sorry for not checking in a while, I have been busy, and honestly, I am looking for as much information as I can get. (pointed to articles, or knowledge) Andyalder: if I understand your statement correctly, then if it is a raided system, then you need to match it to the logical disk in the RAID controller software? so \device\hardisk0 would be the first drive seen on the raid controller?
I have used winobj before, just was looking for a shortcut if there was one.

No, /dev/harddisk0 would be the first logical disk which could be any of the physical disks on the RAID controller. RAID stops the OS seeing bad blocks on the physical disks but if you have a punctured stripe or write hole where the RAID algorithm has failed to repair completely from a previous disk failure it has no option than throw a read error message to the OS. All you can deduce from the OS event log message is that there is something wrong with the array, the controller configuration or diagnostic utility will give more info.
is it a raid system?

it is a variety of PC's .. mostly non raided workstations. Working with monitoring software that is reading the event log. I just didn't want to log into each PC and run winobj plus other additional software to figure it out. I hope I could have a one stop shop command that could be run from the command line. Something like wmic

usually, I have to run something like wmic diskdrive list brief and get something like
Caption DeviceID Model Partitions Size

WDC WD10EZEX-75ZF5A0 \\.\PHYSICALDRIVE0 WDC WD10EZEX-75ZF5A0 3 1000202273280
and then use winobjc to match it up

true - but no media sounds like a dvd driev
how does they show in disk management? (another tool for id'ing)

I will get it to you on Monday. Thanks for your help and patience

I re-read your post. Disk 1 is removable drive. Which I do have a card reader, so that explains that. I guess I will probably have to give up my all-inclusive, easy command quest.
I was hoping to script something.

at least, diskpart gave you the indication : Disk 1 No Media 0 B 0 B

I am closing this abandoned ticket, I am awarding points however, I have learned things I didn't know before. I am still holding out hope (foolishly maybe) of finding a method to fit what I want. (again, running 5 commands on a multitude of machines is not convenient)
Thanks for all your help
