error 512

Hi, and welcome to the forums.

I don't recall seeing a "512" error before.

Take a look at section C in the table of contents of [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum). See if anything there seems to be a close translation.

If not, see #A1 there. Download the widget, and copy and post the log here, along with the exact text of the message you saw (#C2 shows how to find it again). I don't read Dutch, but may be able to find it in the language files.

By the way. The file name for the backup at the moment is:
"EHSH Mac 001b6395b0fb_2010-10-19-220951_2010-10-19-221356_2010-10-20-185506
2010-10-20-191524 2010-10-20-191919_2010-10-21-190748_2010-10-21-193436
2010-10-21-210112 2010-10-21-210502_2010-10-21-225637_2010-10-21-2314182010-10-22-175845.sparsebundle"

There seems to be a strange reference to dates (of which there are no backups made) that to the best of my knowledge wasn't there when the backup was initiated.

That makes no sense. 😟

I take it your backups are on a +Time Capsule?+ If not, what?

How are you seeing that name? Via the Finder?

Hi,

the sparsebundle is on a NAS

Oops. That's a whole different thing. 😟 The "512" error may be coming from your NAS, not OSX. Can you find it in your system.log? If so, see what the sender is. (See the tan box in [OSX Log Files|http://web.me.com/pondini/AppleTips/Logs.html], then the blue one, for help doing that). Copy and post the whole message, including sender, here; maybe we can figure it out.

After selecting the appropriate drive again, I'm now getting the following error message: "backup copy not available"

That doesn't sound like a Time Machine message, either, although it may be a translation. Check it, too, as above, and post it, too.

Any help very much appreciated! Can anyone tell what the correct name it, or where it can be found (maybe in a log or settings file?)

If made +*by Time Machine,+* a sparse bundle should be named +*<Computer name>.sparsebundle+* if made by Snow Leopard; +*<Computer Name>.<12 numbers & letters>.sparsebundle+* if made on Leopard (the 12 numbers & letters are your Mac's hardware address).

But your NAS may have made it's own, or instructed you to make one, so you'll have to check their instructions.
