Now trying R-Linux on both source disks, to see if I can fin anything to recover.

Something went wrong, and I don't even remember exactly what. I thought I'd deleted old, "lost" shares, with the additional typing in of "DELETE" to state clear intentions of doing so, and now BOTH disks are in their respective NAS, but wiped clean. This is part of what I vaguely remember about the last time I did…

This makes absolute sense. My bad. I don't have an empty disk as the intermediate disk to backup to. And I hadn't even thought of it this way. Hence my confusion about how to prevent data loss when inserting a new disk that then gets initialized as ext4.

I've gone the "messy" route :) I interrupted the robocopy process, because I checked the NAS's Storage Manager and saw that the disks inserted are formatted to ext4. I remembered trying a similar thing YEARS ago, only to have the full NTFS disk I'd inserted formatted to ext4 and, thus, lost my data. So I took out the…

Just a quick question, because I MIGHT be doing it wrong: I've left the source disk in the NAS, and am using robocopy to transfer its contents to the replacement drive on an external USB port. I have a nagging feeling I may have had to insert the new disk first, let the NAS initialize it, then copy from the source on an…

I'm running robocopy as I type. Seems to be working well, but slow, as you said. Thanks again for the great suggestion.

Hey, thanks! so Robocopy is built into Windows and runnable from the command prompt? I have Linux on a laptop, if not. I’ve never cloned disks before. Assuming it’s a strict 1:1 copy (hence ‘clone’), how are different disk capacities dealt with? Will I have to re-allocate/add the additional space in the new drive, or is…

Tried unzipping the contents of http://zyxel.diskstation.eu/Users/Mijzelf/RescueSticks/NAS540_521AATB3C0_Upgradekey.zip onto a FAT32 USB drive and tried re-powering up the NAS with the USB in the front and back USB ports, alternatively. In either case, nothing happens. The USB drive has an LED that turns on to show it's…

@Mijzelf: Thanks for the quick reply. I had already tried powering up without disks, and have just tried your suggestion of using the other NAS's power supply. No improvement, unfortunately. Still the same situation. A little extra info, perhaps: the power button lights up, but it doesn't work at all. The only way to turn…

OK, I've tried using the terminal on my Linux laptop to telnet into the non-booting using the IP address I had assigned to it. I get a "no connection/no rout to host" error. Tried the same with the working NAS, after enabling Telnet on it, and I CAN access IT via Telnet. I will try some "fiddling around" on the broken one,…

Hi everyone! I think I may be having the same problem as the OP: After shutting off power to my apartment to change a ceiling lamp, one of my two NAS542's shows the same behavior: when powering ON the NAS, the front power light comes on, but no beeps, no fan movement, no HDD action lights. BEFORE shutting off power to my…
