		<description><![CDATA[&quot;Can you tell me, if TRIM is enabled on the SSD within the OS and you have data on a conventional HDD and you delete a file from the HDD does it bypass the Trash can? Does it get permanently deleted?&quot;

When something is deleted and placed in the Recycle Bin, the data gets moved to a hidden folder on the same drive and remains there until it&#039;s permanently deleted (eg: when the Recycle Bin is emptied). TRIM doesn&#039;t affect anything except data actually located on the SSD itself. 

By your wording, it sounds like you think that when a file is deleted off a hard drive, it gets copied over to the SSD&#039;s Recycle Bin - but no, it doesn&#039;t work like that. Whatever&#039;s in the Recycle Bin is linked to its original location; it&#039;s not all routed through the SSD. 

&quot;My clean 100% untouched backup to them is corrupt.&quot;

This is why I keep multiple backups of the same Acronis .tib file. I&#039;ve only ever encountered this particular issue once, and it was a number of years ago. But I never want to take a chance. I&#039;d also recommend always using the validate option to make sure backups are captured successfully. You can also setup Acronis in Windows to automatically re-validate backups every so often to make sure no corruption occurs. I am not sure where you see a connection to TRIM here, but TRIM definitely has nothing to do with it. TRIM -only- affects deleted data, and on the SSD that said data was on.]]></description>

		<description><![CDATA[Hey, Thanks for your great write up. I got plenty from that.
Can you tell me, if TRIM is enabled on the SSD within the OS and you have data on a conventional HDD and you delete a file from the HDD does it bypass the Trash can? Does it get permanently deleted?
As in...if I have TRIM enabled and delete the file on the conventional HDD within the same OS will I need specific recovery tools to simply undelete it....unlike if the whole system was non-Trim and using conventional HDD where you could just restore from the Trash?

Is there a way of using TRIM and still have Trash can working for all other drives and in particular User data drives. I use my SSD Intell 180GB drive for my OS only and I have several other storage drives in use for other data. I am trying to figure out how to use Windows Shadow copy but only on &quot;some drives&quot; and it seems as though this feature is either enabled r it isn&#039;t no inbetweens in this case? I maybe doing something wrong here but I have not found any info in my searches? Regular backups of these drives means a huge amount of backup storage needs to be free which really sucks. Windows backup cannot backup anything until Shadow Copy service running and a restore point it created. So I am forced to enable the system restore. Run the backup and then disable the system restore. I want to do this for only the SSD but the system restore wipes all restore points when it is disabled which also sucks. It would be great to enable it. Take a snapshot and disabled it and/or disable it for one drive only and keep it running for the rest of the PC.

I switched back to Windows backup also because Acronis completely hosed one of my backups and there has been absolutely no help from any of their tech support. They pretty much shit blame around and basically tell the users that it is their fault that they are doing something wrong bla bla bla I didn&#039;t even waste my time posting on their forums or asking for support after what I had read. My clean 100% untouched backup to them is corrupt. Something I have never had an issue with using the standard Windows backup? So for what it&#039;s worth I went back to using it and said good bye to Acronis backup forever. I will never use their software again. I diverse.

Have you looked at the performance that people are claiming out of the new RAID 0 as well as TRIM? They set up using multiple smaller SSDs, the outcome has tech people throthing at the mouth for this but support from intel is....well.....questionable. Forget older technology being supported. Speeds though are meant to be incredible!
