I kept getting ".error.writing to Target Disk.". I was trying to clone an EVO 840 256GB SSD to a brand new 850 500GB SSD via a no-name USB adaptor (it's worked fine for a couple of years). I hope this helps save someone some time! I would imagine those with thin laptops that can't connect a second drive would need that to work. especially if you kept more than two drives connected and/or if you successfully used a USB/SSD dock/adapter. I would love to hear from you if you have had a similar situation. I think it worked for me because I limited myself to the two SATA drives so there would be no confusion (though that only happened because I needed to use the storage drive's SATA cable and power. Now I may have read this incorrectly, but it suggests to me that you need the Source disk as your first HD and the Target as your 2nd (whether that's configured through plugging into the correct ports on your motherboard or set in your BIOS I am not certain at this time) for this to work.

However, with further investigation, I discovered the following in Samsung's Data Migration Software manual (English - other languages here) under " Limitations" on page 5 of the PDF: I began writing this with the intent to tell my readers that you need to plug it in to the internal and not use an external adapter. This worked like a champ and I'm about 46% finished cloning as I'm writing this.

Unfortunately I didn't have any extra cables, so I had to unplug a secondary internal drive to be able to plug my 850 EVO in. Perplexed because it detected the drives fine, I began investigating.Īfter playing around with a few ideas, I had the thought that maybe it didn't like the fact that I was plugged into an external dock. " An error occurred while writing to the Target Disk" The Samsung Data Migration software happily detected both drives (although the software listed my 840 EVO as a "Generic- Compact Flash USB device"), but when I started the clone, after about 8 seconds, the software stopped with the following error: I connected the 850 EVO via a Thermaltake USB 3.0 dock.

Today I was required to clone a Samsung 840 EVO SSD that has been intermittently failing ever-increasingly in the past couple of weeks. Read on below for more details if you need them. Make sure your source drive is Disk 1 and target is Disk 2 (whether that is forced via physical connections or configured in your BIOS) - please leave feedback if there is a better way to articulate this answer!
