Don't get me wrong, I don't want to blame OP. This is just another example of poor wallet creation documentation and the lack of documentation makes it only worse as time goes by.
It seems to be unknown when the wallet was created, for what purpose and which specific wallet software or web service was used. Not to mention the absence of wallet recovery or backup details. This isn't really a good starting point.
For anybody else, document all what's necessary to recover your wallet and do this in a redundant fashion. Having a single point of failure like just all data on a single harddisk that can fail, will get you in trouble sooner or later. Also, stuff you've done years ago and which has been left untouched for long time will very very likely vanish from your human memory. It proves all so often that people can't remember sufficiently what they've done exactly years ago when specific details matter.
That your six words appear to belong to six different language dictionaries is very unusual. I can't think of a sane wallet software that would use something mixed up like this.
My initial thoughts on what those words could be have mostly been suggested already by others:
- a brainwallet phrase, i.e. SHA256("word1 word2 ... word6") gives you one private key or 256 bits of "entropy" for further derivation
- a wallet encryption passphrase (you're still screwed without the wallet file itself)
- could also be an optional mnemonic passphrase, but then the mnemonic recovery words are missing
- some fancily chosen words for your own self-constructed and shoot-you-in-your-foot scheme when there's no documentation for it
- if BIP39 already were a thing when OP created the wallet, it would be uncommon but still possible to feed the six mixed language words into the 2048 rounds of PBKDF2 and continue BIP32 root key derivation from there (but then still some more details like derivation path and such are missing and you would need some tweaked script of software for it as e.g. the iancoleman.io/bip39/ script won't accept mixed language words from dictionaries it doesn't know about (this idea is a bit far fetched, I'm just brain-storming and it's sometimes hard to think of what some users come up with))
wallet data was in my old pc that it's hdd has completely broken.
No chance you might have a partial backup of important data that was on this single hdd on some other storage device?
Why don't people make backups?
I'm almost sure it is six words seed.
I would say that's highly unlikely. First, it's a bit too few words for recovery seed words. Second, why would it be mixed language? This only complicates things and I'm not aware of any sane wallet software that does mixed language recovery seed words.
That's an interesting find, at least when all used language dictionaries are in one place from which your words may origin.
Frankly, what exactly would a "base58 wallet" be? I've no idea what you're talking about.
