The only Cisco related question i can see would possibly be:

Which wireless security technology is a good choice when using Cisco equipment in conjunction with operating systems such as Windows and Linux?
LEAP
WEP
WPA
WTLS

And with that question i would answer WPA

gparted destroying my backup drive?

Filed under: Windows Disaster Recovery — wayne @ 12:49 pm

I’m ultimately about to ask about partition recovery but please read on for the specifics!

Well today has been a techno disaster

Windows went down so booted to an old 6.06 lts ubuntu live cd to fix the mess.

Decided to do a backup of my important files first so connected my 1TB drive with lots of important files…..but of course ubuntu couldn’t write to ntfs properly back then so hit a problem.

To solve it I fired up parted switched to my backup drive. Which had all the options grayed out as it was mounted.

No matter. Terminal > sudo umount /dev/sdb

….not found.

After a seconds thought I right clicked the desktop icon for the drive and chose eject. Then refreshed parted. Options ungrayed result.

Entered two changes: resize the original ntfs backup partition with all of my files on it to leave 7odd th at the end. And reformat that empty space with extra3.

Selected option to write changes to disk.

Task one started then suddenly ubuntu remounted the drive of its own accord before the first task had completed. I can only assume it has some misguided urge to mount external disks.

An error screen also popped up which I closed too quickly without reading it as I wrongly concluded it was the second new partition which had also been mounted.

Now gparted shows the disk as divided into two with both marked as of unknown filesystem. The second takes up no actual space but appears on the list. The first has maintained its boot flag.

Help how do I recover my backup partition??
Sorry for typos Android phone prediction run amoc

Parted = gparted

I once had a similar problem and TestDisk was able to recover the partition

Can you answer true or false to these computer questions?

Filed under: Windows Disaster Recovery — wayne @ 8:40 pm

1) A floppy disc is actually a piece of Mylar similar that is used for overhead transparencies
2) A 3 1/2 inch high density floppy disc has 224 entries in the root directory
3) Subdirectories can have as many entries as disk space allows
4) You may share IRQs with ISA devices on the ISA bus
5) THe number of memory addresses is partly limited
6) Hard copy is a term associated with a printer
7) Newer motherboards typically do not provide a connection for a floppy drive
8) Most SRAM now inside the processor housing
9) WHen examining memory measured in nanoseconds, the larger the number, the faster the memory
10) CISC CPUs are typically faster than RISC CPUs
11) One port fails on a non critial machine. You shold replace the motherboard
12) In windows 9x, a compressed drive is not a drive at all, its a file
13) Hardware disk cache is faster thank a software cache
14) You should verify that your recovery plans works by practicing it before disaster occurs

Thanks for your time

How will you learn if I tell you the answers? But here they are:

1. False – it’s a magnetic surface
2. True – yes, 224 root directories possible
3. False – Windows has a limit on directories and subdirectories- 255 deep maximum.
4. False – ISA are memory address specific-no sharing.
5. True – only sixteen IRQ but with port steering and USB managing them, it can appear to be more than sixteen.
6. True – hard copy/paper copy
7. False – Yes they do in case you want to use them.
8. False – SRAM is on cards, HD and hardware -too slow for processor.
9. False – smaller is always faster
10. False – less instructions to prevent slow down of processing time.
11. False – Just use another port if available
12. True – A compressed drive would not function-only a big file.
13. True – way faster!
14. True – of course!

Let me know how I did on your homework. 🙂
