Backup Harddrive is immune to every chkdsk attempt

Folks,

I've got a Samsung spinpoint 1 Tb drive. It was a backup drive in a Vista build. I used Macrium to clone my Vista C drive to the Samsung. Then, I removed it.

Next, I built a new machine, a W7/64. THAT build uses an SSD for the operating system, "C", and a Western Digital hard drive (Black, 1 Tb) as the data drive, "D".

Once that machine was up and running, I decided to use the old Samsung drive as a backup. I physically installed it, Sata cable, and it is identified in windows as "E". Next, I tried using the Disk Management, Properties, Tools to run check. The window opens, then it immediately closes.

hmmm, thought I. Perhaps a remnant of the Vista OS was doing something. I then opened Disk Management, unmounted the drive, and performed a complete, long, reformat.

I restarted.

I tried using the properties, tools, check now window again. Still, that window will not check it. The progress bar never flashes. All that happens is about 1 second after I click "OK", the window closes. No messages.

I opened an elevated command prompt and tried "chkdsk e:" It came back with "The type of file system is NTFS." A pause, "Errors found. CHKDSK cannot continue in read-only mode."

I've searched a LOT of the internet on this. The drive has just under 9,000 hours on it. It passes every Samsung test I could throw at it from Samsung's support website.

Windows disk checking seems not to work.

How can I verify the disk before I trust my data backups to it?

Thanks,
Ken

I can rename the drive. Windows sees it. I can copy files to it. I can read files on it.

hi, in disk management is it shown as a basic or dynamic disk? also can you take a screenshot of what it gives you in dispkpart like my picture below when you do detail disk.

Thanks for the assist.

Here are some screenshots. (I went through the install new drive wizard in the meantime. It is now called "New Volume".)




This is what I was trying to do which has led to the problems:



When I hit "start" (whether I have the second box ticked or not), the "Check Disk" window greys out, the progress bar stays blank, and a second or two later it disappears. No drive activity noted.

Finally, here's the diskpart screenshot:



I hope some of this helps!

And thank you for taking the time to help me out.

sorry took so long to reply, unfortunately everything seems to look okay on this end. you could try recreating the partition with diskpart select the disk then (make sure it's the right disk) type (leave out the quotes) "clean" and hit enter and it will wipe the whole disk of everything then do "create partition primary size=(then put it in as MB for this test just put 900000)900000 so the whole thing is "create partition primary size=900000"
then type exit and see if you can error check it after a reboot of the pc.

rvcjew,

Thanks. I tried what you suggested. No change.

I split the drive into 2 partitions and tried to surface scan each partition, in turn. No joy.

It -seems- to work. But, without full access to it via chkdsk, there's no way I can trust that the drive isn't somehow corrupted.

NoelDP,

Thanks. (I've tried, but I retried. Results below.)

Here's the "My Computer" and "Disk Management" screen:



The disk in question is disk 2, "Spare". Frankly, at this point, I've forgotten how many times I've formatted it, both long and short.

Here's another DISKPART shot:



What is odd, very odd, is what this shows. Disk 2 =should= be a GPT disk. It has no asterisk indicating that. Look upstream a few posts. Back then, it did. (In between I partitioned it, then un-partitioned it.) I went through the W7 new disk wizard and set it as a GPT disk with 512Mb sectors. I don't know where the 1024 Kb comes from.

Finally, here's what happens when I run chkdsk with an elevated command prompt:




I've tried to run chkdsk from the elevated command prompt countless times. I either get the error shown, above, or an error which states that it cannot complete a check of a disk in "read-only mode". (That's a paraphrase, it's pretty close to that.)

At this point, I'm getting close to opening the hard drive, rubbing magnets all over the disks, wrapping it fine copper wire, applying rapidly varying voltages, spinning them at high g's, baking them at 200C (or higher), spraying them with cold helium, and subjecting them to verbal abuse, all in an attempt to wipe out whatever is going on. :)

Thoughts?

Hmmmm (warning - I'm in the pub) from that result it looks to me as if the OS drive isn't properly recognised.

i agree chkdsk should say it cant be done being mounted then prompt you to reboot and schedule it for next reboot. try this: How can I force a disk check when Windows 7 reports "Disk checking has been cancelled"? - Super User that will allow you to force it in the registry for next reboot.

Guys,

My setup has an SSD as Disk C, the OS disk. It's identified as Disk 0 in diskpart.
Then, I use a 1Tb hard drive for data, Disk D. It's identified as Disk 1 in diskpart.
The disk in question (diq?) is Drive E, disk 2. It -had- a clone of Vista from a different machine. Now, I want to use it as a spare for this machine. Wiped of anything that had been on it. Pristine, and clean.

That disk, E, should have no data left on it in any manner. I've partitioned it, I've formatted it, I've reformatted it, ad nauseum.

As such, I wouldn't think a surface scan (or chkdsk /r) would require any kind of reboot to be performed. Regardless, there has been no message about such a need. If I try the elevated command prompt for the disk scan, I either get the error string, above (I googled it and it didn't point to any solutions), or I get the "can't do it on a read only disk" message. If I try the windows 7 tool, the tool window greys out and disappears within a second. No error message, no disk scanning.
