I have a Toshiba Satellite P745 with 750 GB internal HD, I ran Hard disk generator 2011 (from a bootable CD) over night, after 14 hours it got to 0.64% scanning 4500 Mbytes and finding 560 bad sectors 116 of them was regenerated.
I canelled the operation because it seemed like something was wrong. My questions are:
1-What's the acceptable number of bad sectors in any HD?
2-Should I re-do the scan even with that speed? the software told me to change my BIOS settings from AHCI to compatability, is that the reason the oepration ran so slowly?
3-Is my HD dead?
4-If I get a replacement can I use the old one as an external storage after chopping off the bad part of it?(even If I can use 100-500GB out of 750!)
5-would any internal HD work as a replacement?
6-Is it better for my laptop's preformance to get a smaller hard drive (say 320GB)?
7-Will the system recovery disks work after the replacement (even if it was a smaller hard drive)?

1. Run a smart scan
2. It shouldn't be that slow in IDE mode. Find a utility for the brand of hard drive.
3. It might be dead, more testing needed. What made you test it in the first place?
4. If it is still working you can get a USB enclosure to put it in.
5. As long as it is SATA and not to thick. Most laptops take a drive 9.5 mm or less thick.
6. A smaller drive won't necessarily be faster. A SSD would be much faster.
7. The recovery disk should work on a smaller drive. If your existing drive still works to some degree it would be easier to clone the drive.

I found a utility in Hirens boot CD for toshiba hard drives, tried to run SMART test but it ended with an error "fail". I ran the test because windows and ubuntu told me through different warnings that my disk is likely to fail and that I should start a back up process.
does my laptop support SSD? I don't really know much about SSD.

Here's my SMART test results from HDD Low Level Format Tool 4.25:

I don't know what to make out of these results, is the disk finished?
