Problem with many/large HDDs
Windows 7 Professional.
Mounted in the case is 1 80MB and 1 300MB drive. SATA.
I have SATA power and datacables hanging out the back of the case.
I also have an (open) external USB 2 drive.
I have a number of data drives (with backup copies of each drive) which I usually plug into the USB box when I need them. These are 1TB and 2TB (partitioned into 1TB).
Usually, using the USB box is succesful. I get 28MB/s transfer speed writing to the drives. Although sometimes I can see the drive in "Safely remove hardware", the drive does not appear in Windows Explorer until I run Partition Wizard. I don't have to do anything, just run it and then exit.
However, plugging in a SATA drive (after powering down) firstly makes Windows take ages to boot.
Then when trying to transfer data it starts off fine and then grinds almost to a standstill, saying it will take 3 hours to transfer 4MB of data.
Needless to say, the same happens if the drive is mounted in the case. It was this problem that prompted me to make them "external" drives.
I can't see any difference in the problem if the drives are Samsung, Seagate or Western Digital.
The problem can occur using Windows Explorer and Microsoft SyncToy.
Sometimes problem does not occur.
I need to have 2 drives plugged in when making a copy as a backup.
