File System is found ?

Tony, file system errors are normally issued because such an issue has been found on the disk that is identified in the error message.
Note: Acronis counts drives starting at 1 but Windows starts at 0, so if Acronis says there is a file system issue with Disk 1, this is Windows disk 0 as shown in disk management.

CHKDSK will only check partitions / drives that have an allocated drive letter but these errors can often be found in other hidden / system partitions with no drive letter.

Dedicated diagnostic utilities from the disk manufacturers take the longest time to complete the checks, but provide the most accurate methods of checking whether the disk is good or needs replacement:

 - Western Digital drives: Data Lifeguard Diagnostic for Windows

 - Seagate disks: SeaTools for Windows

 - HGST disks: HGST Windows Drive Fitness Test (WinDFT)

 - Intel SSDs: Intel Memory and Storage Tool (GUI)

 - Samsung drives: Samsung Magician

 - ADATA drives: ADATA SSD ToolBox

 - Kingston SSDs: Kingston SSD Toolbox, Kingston SSD Manager

 - Transcend SSDs: Transcend SSD Scope

 - Silicon Power disks: SP ToolBox

 - Toshiba disks: Toshiba PC Diagnostic Tool Utility

 - Crucial disks: Crucial Storage Executive

Hi Steve.

I have a Sandisk SSd Plus 1Tb hard drive.

I have run the utilities but it doesn't show any problem.

Life remaining 98%. Max temp 37'C. Firmware is up to date.

The PC is running well with no obvious running problems.

I could try a system repair disk or reinstall windows I suppose.

My knowledge is limited so not sure where to go next ?

Tony.

Tony, what is the exact error message, what disk is indicated and how many disk drives are connected?

The log file may be the best way to understand the error better.

There is a new MVP Assistant log viewer tool that has now been made available by Acronis via the Community Tools page.. 

If you have Disks & Partitions backups created on ATI 2020 or later using .tibx files, then look in the Backup Worker logs.

If you have Files & Folders backups using .tib files (or Disk backups from earlier versions using .tib files) then look in the Demon logs.

Other logs are shown by the MVP Assistant under the 'Active Logs' heading of the Log Viewer page of the Assistant.

The log files should be zipped to preserve their original file names if sharing in the forums and would need to be less than 3MB in size, otherwise you would need to share the zip file via a Cloud share service such as OneDrive, Dropbox etc.

Hi Steve.

I downloaded a Sandisk SSD utility but it didn't find any problems on the SSD drive. I also downloaded MVP assistant but to be honest I've no idea what I'm looking for. Sorry its over my head.

I also tried a few things to see if it fixed the problem.

I've forgotten the error messages so have decided to start with a fresh Acronis copy.

I uninstalled Acronis & reinstalled the program again & I'm now trying a backup.

Its running at the moment so we'll see what errors it comes up with if any.

I'll make a note of them & post them here.

Tony.

Acronis did a couple of back ups at 19.19 & 19.36 & 20.06.

However it shows an error underneath.

Not sure where to go from here ?

I had this error message previously.

I've tried various SSD drives.

There are two external 2'5" & two external SSD drives attached to the PC.

Tony.

Tony, as you creating an 'Entire PC' type backup and have several disk drives, the best way forward would be if you could zip up the Backup Worker logs and use the File > Upload option to share that here in the forum topic.

The folder to zip is C:\ProgramData\Acronis\TrueImageHome\Logs\backup_worker

One other piece of information that would be helpful for this scenario is to create an Acronis System Report and extract just the disks.txt file from the zip file this creates in the C:\Program Files (x86)\Acronis\TrueImageHome folder.
Note: the actual systemreport.zip file is likely to be too large to upload to the forum due to the 3MB maxium file limit imposed!

Steve.

I have enclosed Backup Worker if its any help ?

Tony.

Tony, there are 2 separate but related errors shown in the logs:

08/04/2021 06:48:43:372 PM type=commonerror; value=?5cA??@?A backup error.
$funcAda_backup::Commit
$lineNa??(????Read error.
$funcA`anonymous-namespace'::PartitionBackuper::ReadDrive
$lineN_Z???v???Failed to read the volume.
$funcAwin_snapshot_volume::IoOp
$lineN'U?R?*{??CRC error.
08/04/2021 06:48:43:372 PM type=log; level=inf; message=lsm#1: dedup_map nr_lookup=647847 nr_found=14411 false+=14366 (2.22%/99.69%);
08/04/2021 06:48:43:372 PM type=retcode; value=4095; id=1;

The above error equates to the file system error reported.

08/04/2021 08:06:39:214 PM type=commonerror; value=?5cA??@?A backup error.
$funcAda_backup::Commit
$lineNa??(????Read error
$funcA`anonymous-namespace'::PartitionBackuper::ReadDrive
$lineNe????v???Failed to read the snapshot. See VSS logs for details.
$funcAwin_snapshot_volume::IoOp
$lineNU?R?*{??CRC error.
08/04/2021 08:06:39:214 PM type=log; level=inf; message=lsm#1: dedup_map nr_lookup=926546 nr_found=457365 false+=456129 (49.23%/99.73%);
08/04/2021 08:06:39:214 PM type=retcode; value=4095; id=1;

The second error is caused by file system errors associated with where Windows stores VSS snapshot data created by Acronis and which cannot be read in order to be saved to the backup drive.

I would suggest the next step should be to try to isolate this issue to a specific disk drive instead of using the 'Entire PC' option.

If you create a new backup task, and when it shows 'Entire PC', click on this to 'Change the Source' then click on Disks & Partitions to see a listing of all the disks identified in the PC.

Select a single disk for the backup and test whether you see the file system error or not?

Thanks Steve.

I'll check out your suggestions tomorrow & let you know how I get on.

Thanks.

Tony.

Hi Steve.

I booted up the PC this morning with only the Internal C drive & an External 2'5" Acronis backup drive attached.

I ran Acronis & this is what happened.

Last backup today 09.43 (No errors reported)

Last backup today 10.00. The latest backup has been stopped. It will be restarted at 10.01

Last backup today 10.16. (No errors reported)

Last backup today 10.48. (No errors reported)

Last backup today 11.04. * File system error is found. Consider checking the disk using Check Disk Utility.

Next backup 15/04/2021 at 17.41.

I have included the latest backup-worker file.

Tony

Tony, all the new logs are still showing the same Failed to read the snapshot error.

Please download the Acronis VSS Doctor tool (link in my signature) and run this to see what issues this flags up.  If the tool offers to fix any errors, then let it do so.

Steve.

It offered to fix issues which I allowed.

These are the reports. Before & after running the program.

What should I do now ?

Tony

Tony, the VSS Doctor shows very many repeat entries for VSS related errors over the past several days.

Timestamp: 09/04/2021 11:04:36
Type: Error
Source: disk
Message: The device, \Device\Harddisk0\DR0, has a bad block.
InstanceId: -1073479673
SearchLink: https://www.google.com/#newwindow=1&q=disk+event+id+3221487623

 See webpage Fix: Event 7 Disk has a bad block at \Device\Harddisk#\DR# found by following the link given in the error message.

Or webpage: Fix: Device Harddisk DR0 has a “bad block” Error in Event Viewer

Essentially, these events are telling you the same thing, that your disk 0 drive has a problem which is causing these file system errors to be generated when the failing / bad block on the drive is encountered by any application, including the Microsoft VSS snapshot service.

You may need to contact SanDisk to see if they have any other tools that can help resolve this bad block issue with your SSD?

Tony, do you have the SanDisk SSD Dashboard tool installed on your PC, and if so, have you tried running the Diagnostic Extended Test provided by that tool?

See the SanDisk SSD Dashboard user guide for details.

Steve.

I ran Sandisk Dashboard.

I then ran S.M.A.R.T. Diagnostic Short Test & that showed no problems but when I ran S.M.A.R.T. Diagnostic Extended Test it came up with a result of Error Code 3. It seems to have bad blocks so I've submitted a question to Sandisk.

When they reply I will post it here.

This is the smart data from the program.

Hi Steve.

Sandisk got back to me with the following:

"I understand that you are not able to backup your SSD Plus 1000GB Drive using Acronis True Image.

In addition you have informed that the SMART Test in Dashboard fails with error code 3.

Error code 3 is generated when an error prevents the SMART test to complete. This error might also be related to another component or a corruption in the operating system.

Can you please try to run a SMART Test to the drive using a 3rd party application? An example application is Crystal Disk Info.

Disclaimer notice on using Third-Party Websites or Software.

If the Smart test completes and does not report issues, the issue might be related to a corruption in the Operating system. If this is the case, please perform a manual backup of your important files and try to format and clean install the operating system.

Please make sure to write what happens when you try the advised steps.

If the issue persists, please provide us with the following information so we can process a warranty replacement.

• Date and place of purchase

• Phone number (for shipping & technical support call back only)

• Shipping address (no P.O. Box please)

• Do you consent to sharing your address with our shipping provider?

Note: Refurbished, physically damaged or non-authentic products are not covered by SanDisk® warranty. 

Best regards,"

Having gone through the various suggestions that were made I ended up refreshing the Windows 10 operating system.

This seems to have solved the problems I was having with Acronis as I'm getting no errors now.

I want to do a full backup followed by backups which only backup what has changed since the previous backup.

What Acronis backup would be the most suitable for this ?

Thanks.

Tony.

Tony, glad that the issue with the SSD looks to be resolved!  See the following references for making backups.

KB 63239: Acronis True Image 2020: how to back up entire computer

KB 63252: Acronis True Image 2020: how to back up files or disks

I typically use Incremental backups using the default settings to create a new full backup after 5 or 6 incrementals, plus use Automatic Cleanup with the option to 'Store no more than 2 recent versions / version chains' which suits my own needs and the available backup storage I am using.

Hi Steve.

Thank you for all the advice you have given me. Its very much appreciated.

I will follow the links you have given me.

Thanks.

Tony.

Steve.

I ran Sandisk dashboard & this was the result.

The Smart Diagnostic Extended Test completed.

One or more problems were detected.

Failed with error code 3.

I think at this stage despite reinstalling the operating system that the SSD drive has problems & needs to be replaced. I have contacted Sandisk & await their reply ?

Tony

Tony, thanks for the update, hope your request to SanDisk for a replacement is dealt with quickly for you!

Hi Steve.

Had a reply from Sandisk this morning & they have agreed to send out a replacement SSD drive.

Tony.

Good news Tony!

Sandisk got back to me.

They received my return & found the SSD drive as faulty.

A replacement has been issued & is due tomorrow.

Before I sent the drive back I cloned it with Acronis Clone Clone disk to another SSD drive.

That drive is running happily in my PC & Acronis backs up without any problem.

Tony.

Further good news Tony!

New SSD drive arrived this morning.

I will keep it as a spare.

Thank you Steve for your help in this.

Regards.

Tony.

Tony, it is always good to have a spare disk on hand. That said, the only SATA SSD I have on hand are old ones, one with capacity of 120 GB and the other with capacity of 120 GB. I have no spare M.2 NVMe SSDs. Fortunately I have yet to have an M.2 NVMe drive fail - did have some SATA SSDs fail in the early days (I discovered in two instance it was caused by a faulty power supply).

You can never have to many spares Ian.

No problems since I'm glad to say.
