Which of the following sentences is correct or better?
I have been using this software for about one year.
I have been using this software for around one year.
Searching in Google gives 14 million hits for "for about one year" and 1.5 million hits for "for around one year". Seems that "about" is better, but my test is not very conclusive.
Both Merriam-Webster and Wiktionary only mention disable as a verb.
After seeing the background you provided, I would go with idle time (898,000 Google hits vs 36,000 hits for disable time). The Business Dictionary suggests waiting time as an alternative.
Edit: as pointed out in the comments by Kosmonaut and Bruno, yet another alternative would be disabled time or perhaps time disabled (with a participle rather than the infinitive form).
The most natural is:
This test data doesn't seem to be good.
The following two, although not incorrect per se, are less common:
This test data seems to be not good.
This test data seems not to be good.
And the last one sounds rather unnatural:
This test data seems to not be good.
Ngrams confirms it:
I am afraid I can't explain the why part, so I'll leave it to other answers :)

Either one is fine. There is absolutely no meaningful distinction between the two in this case.
