Acronis B&R Workstation and Samsung S2 External USB Hard Disk

Thread needs solution

Hi,

We are using Full version of Acronis B&R for Workstation, until now we doesn't have any problem with software, it was making backup on 2 external usb hard drives, 1 toshiba 500GB and 1 iomega 320 gb. Two weeks ago we buy a Samsung S2 500gb External hard drive to replace the iomega hard drive.

The problem is, when I connect the samsung hard drive appear a message "Acronis Managed Machine Service is unavailable". I try to stop the service manually, but the status become stopping. The only way I can recover machine and service is disconnecting samsung USB hard drive.

I already try the software on a clean machine (just windows and acronis), same result.
Following chat support advice I install the last recommended snapapi.exe, restart, but the error start againt when I connect the samsung external hard drive.

I try this using windows XP Professional and Windows Vista Business, 32 bits both. Samsung S2 Hard Drive is properly recognized by system, I can access it, write and delete data.

Exist any solution for this problem? chat support cannot provide any to me.
Can I get a list of validated usb (or firewire) external usb compatible devices with acronis? My hardware provider is asking me for one.

regards,

Juan Ramirez,
PD: Excuse my basic english and if I wrote with gramatical error.

Hello Juan,

Thank you for posting your question, I will be happy to help.

Most probably, the new USB drive has the 4 KB cluster size. Components of Acronis Backup & Recovery 10 Build 11133 or lower cannot handle the 4 KB cluster size properly. Therefore, there are two ways to fix the issue:

1) Please download and install the latest build of the program (build #11345). The encountered issue has been fixed for this build. You can learn more on how to download the latest build in this article. Update the components and see if the issue remains.

2) You can reformat the hard drive selecting another than 4 KB cluster size. Please note that you are unable to change the cluster size without loosing your data, therefore, please copy the data to another location prior changing the cluster size.

Please let us know the results, we should be sure that the program runs flawless for you. If the provided information is not clear or if you have any other question do not hesitate to post them and we will be glad to answer.

Thank you.

4 kb is a most common cluster size for NTFS, so any build of it for sure can handle this cluster site. It's the nonstandard sector size that causes the trouble.
