Sector by Sector compression?

Thread needs solution

Hi,

 

According to https://kb.acronis.com/content/16791 There is a choice for the compression level when doing a sector by sector backup for a HD image.

 

On most of my pc's using a ssd HD this works fine yielding an image similar to the size of the contents on the HD

 

On one particular PC when using Sector by Sector backup of the HD, no matter whether I choose Maximum Compression, High Compression, Normal Compression or NONE, it makes the image 1 tb ( size of SSD HD) even though contents are only 40gb.

 

I did an experiment on that PC and substituted another SSD and backup image was equal to the contents sitting on the drive NOT the capacity of the entire HD

 

The drive giving an issue is a Crucial 1 tb  SATA NAND SSD. Crucial model # CT1000MX500SSD1(Z)

 

Is it possible Acronis does not play nicely with certain SSDS?

 

Thank you

 

Jeff

Jeff, the KB document you referenced is some years old and does not cover the latest ATI product versions beyond 2016, so not sure whether this is still relevant other than the fact that Acronis still uses the ZLIB compression libraries in ATI 2019.

I suspect that your Crucial SSD does not present sector information in a way that Acronis fully recognises in order to determine what are used and unused etc, hence the whole drive capacity is being captured.

I would recommend opening a Support Case directly with Acronis for this question on why the compressed archive sizes differ so greatly for different SSD / HDD products?

Steve,

 

The crazy thing is ATI 2019 and 2017 work well on any other PC and or HD, just this particular HD gives ATI an issue and will only copy the entire HD capacity only in SBS mode

Jeff, I guess the next question is whether this is just this one Crucial SSD or whether it would be the same for any Crucial SSD?  I have never had a Crucial disk so not encountered this type of issue previously - all my drives have tended to be Seagate or WD with the exception of some much older Toshiba & IBM drives which were IDE (aka PATA) vintage.  Think I have a Samsung SSD in a Netbook!

Steve,

 

All other crucial SSDs 500gb 750gb work perfectly, only this newer 1TB SSD are there issues with SBS

Jeff, may be worth looking at the Crucial Support site for any firmware updates for your drive, plus to see if the Crucial Storage Executive software would throw any light on this issue?

Steve,

 

I downloaded crucial executive, latest firmware already there.

 

I think it is a SSD issue since all other ssds work with ATI 2017 or ATI2019

It certainly sounds like there is an issue with this particular SSD Jeff.
