|NTFS File System Driver version and size compared between Win2008 and Win2012|
If the initial statement is right and the NTFS version is the same, I should be still able to read this external deduplicated drive with Windows 2008 R2. My test revealed this to be true. I can see the USB drive and browse its folders but, when I try to open any file bigger than 32 kbytes, I get the following error message:
|Error 0x80070780 The file cannot be accessed from the system|
Get-Item 40kb.txt | select Attributes | fl Attributes : Archive, SparseFile, ReparsePointOn smaller files, only the 'archive' attribute is present:
Get-Item 20kb.txt | select Attributes | fl Attributes : ArchiveSo, the attributes of a deduplicated file are: sparse and reparse point.
I thought it would be useful to share my experience on this in case somebody need it.
