Out of space on computer? Want to buy new disc? Well I strongly advice you to think over if your ebay deal is legit. Because you may run from this:
This has been found somewhere in Russia, the guy has reported it as broken at PC repairman. This HDD was able to hold only 5 last minutes of a movie.. as it is 128MB flash memory configured to overwrite everything as it reaches it's limit.
More information HERE.
I hope that I will never buy such crap ;)
