Hello, I'm trying to create a volume shadow copy image using
$ dd if=/proc/sys/Device/HarddiskVolumeShadowCopy9 of=/dev/null bs=4096 status=progress but it ends prematurely with 116923437056 bytes (117 GB, 109 GiB) copied, 65 s, 1.8 GB/s dd: error reading '/proc/sys/Device/HarddiskVolumeShadowCopy9': No space left on device 29139072+0 records in 29139072+0 records out 119353638912 bytes (119 GB, 111 GiB) copied, 65.5664 s, 1.8 GB/s If i use Windows Command Prompt then it finishes successfully: C:\tmp>\cygwin64\bin\dd if=//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy9 of=/dev/null bs=4096 status=progress 119288205312 bytes (119 GB, 111 GiB) copied, 471 s, 253 MB/s 29139074+0 records in 29139074+0 records out 119353647104 bytes (119 GB, 111 GiB) copied, 471.14 s, 253 MB/s If I use count=29139071 then it works in both environments. Any ideas? I haven't subscribed yet so Cc me please.
