Shamus_McFartfinger Posted February 17, 2006 Posted February 17, 2006 Anyone done this recently? What a slooooooooooow process it is. 20 hours it took for a P3/550 to zero fill a 400gig drive. Eager to improve things, I threw another 400gig thingy into a P4/2.4 last night expecting it to be a little quicker. Nope. 24 hours later and it?s at 76%. WTF?
lfcrule1972 Posted February 17, 2006 Posted February 17, 2006 I have never done that mate !! My original HDD is a 40gig, I think my iso HDD is an 80gig one, you are way out of my league.... <curious> Is this something you do to check write speed to the HDD or for some other reason mate ? How do you do it ? (Google ??? )</curious>

In dos mode(pio)/ it doesn't matter what cpu, writing zeros/a low level format is dependent upon the size of the hard drive. Haven't done one of those in about 4-5 years. I did recover some drives with errors on them then and returned to factory certified condition. After using zap and wipe I never did a low level format again. Edited February 17, 2006 by chewy
LIGHTNING UK! Posted February 17, 2006 Posted February 17, 2006 Did it the other day about 10 times to a hdd I need to RMA with Maxtor. Using my own little HDD Tools program of course Didn't take anywhere near as long as your one though - my transfer rate was about 70mb/s

When you say "zero fill" do you mean writing zeros to all of the unused space? Edited February 17, 2006 by Movie Junkie
LIGHTNING UK! Posted February 17, 2006 Posted February 17, 2006 I'd imagine he means the entire disc - as in wiping everything (filesystem included) off it.
Movie Junkie Posted February 17, 2006 Posted February 17, 2006 Thanks LUK. Shamus: With some of those programs you have the ability to change the number of times it writes the zero to each block. With the program I use it can be anywhere up to 255 times. If you have it set to a high number of writes that could be why it is taking a long time to complete.

(Google ??? )</curious> I used Seagate?s formatting tool and after 30 hours it failed to do what it was supposed to do. *sigh* You can have a bit of a read here if you like. http://www.seagate.com/support/kb/disc/faq...llfmt_what.html
Shamus_McFartfinger Posted February 17, 2006 Author Posted February 17, 2006 In dos mode(pio)/ it doesn't matter what cpu, writing zeros/a low level format is dependent upon thesize of the hard drive. I understand this bit but it makes you wonder why there would be 10 hours difference in the time it takes.
Shamus_McFartfinger Posted February 17, 2006 Author Posted February 17, 2006 Did it the other day about 10 times to a hdd I need to RMA with Maxtor. Using my own little HDD Tools program of course Now THERE?S an idea. Why didn?t I think of that? Good thinking, mate. Didn't take anywhere near as long as your one though - my transfer rate was about 70mb/s Sounds a hell of a lot better than 2mb/s.
Shamus_McFartfinger Posted February 17, 2006 Author Posted February 17, 2006 I'd imagine he means the entire disc - as in wiping everything (filesystem included) off it. Yeppers. Basically returning the drive to its factory state.
dirio49 Posted February 17, 2006 Posted February 17, 2006 (edited) Using my own little HDD Tools program of course Is there any posssibility of you sharing that proggy? I tried once using Darik's Boot and Nuke. It's Ok but i got lazy and canceled it. Edited February 17, 2006 by dirio49
Grain Posted February 17, 2006 Posted February 17, 2006 I also had trouble w/ a Seagate's program, their SATA HDD format proggy, didn't invest near your amount of time though, ended up using Windoz formatter , but it worked.
dbminter Posted February 18, 2006 Posted February 18, 2006 Of course, it also depends how you're zeroing out the drive. Writing just a zero to every area is faster than, say, the more secure wipe method of writing a 0, erase it, write a 1, erase it, write a 0, and check that the write reads 0, and repeat for 32 passes. It might just be easier to use something like Partition Magic to safely delete the partition, create a new, blank, unformatted one in the empty space, image the partition, then safely delete the new partition, create a 2nd new blank, unformatted one, and then restore the imaged partition, and safely delete it. While it seems like a lot of useless steps, the partition sizes will be small since hardly any data will be used, thus, making the restores, creations, and deletes quick. Plus, creating and deleting multiple partitions to the same area should make it very difficult to recover anything through means beyond electron tunnelling.

No choice in the matter with the Seagate tools. It would have been nice if they included code that enabled DMA. PIO might be fine for a 20gig drive but for anything larger it?s a painful experience.
Shamus_McFartfinger Posted February 18, 2006 Author Posted February 18, 2006 Didn't take anywhere near as long as your one though - my transfer rate was about 70mb/s Just got home from work and threw the drive in another machine and started HDD Tools. 30mb/sec. Something tells me I need to replace a ribbon cable and have a look for a BIOS update. ETA is 3 1/2 hours. Damn sight f*cking better than 30. Great proggy mate.
LIGHTNING UK! Posted February 18, 2006 Posted February 18, 2006 Don't forget the new 0.0.0.5 version mate 30mb/s does kinda suck though mate... there must be something wrong there (as you rightly said!). Mine actually starts off at around 85mb/s and I'd have expected yours to be 65 - 75 if that drive is anything like my ide/sata ones.
dirio49 Posted February 18, 2006 Posted February 18, 2006 (edited) So LUK, there is no chance of you releasing that program. so people can take it for a test run. Edited February 18, 2006 by dirio49
Shamus_McFartfinger Posted February 18, 2006 Author Posted February 18, 2006 Don't forget the new 0.0.0.5 version mate Just grabbed it. 30mb/s does kinda suck though mate... there must be something wrong there (as you rightly said!). Yeah. I?ll have a look on the weekend. I can?t see anything in the BIOS that would slow it down. Mine actually starts off at around 85mb/s and I'd have expected yours to be 65 - 75 if that drive is anything like my ide/sata ones. I thought they?d be alot quicker as well. The drives are fast enough but seem to have a problem communicating somewhere. (2 minutes later) I?ve just checked the nVidia SATA/IDE driver settings and they?ve been set on auto from the BIOS to DMA33. Gee. I wonder why my drives are slow. (5 minutes later) Getting excessive errors from the drives at DMA133 which is why it defaulted to DMA33. It?s a sure bet my ribbon cable is stuffed. Getting 70mb/sec ATM though. 4am. Bedtime.
dirio49 Posted April 14, 2007 Posted April 14, 2007 So LUK,there is no chance of you releasing that program. so people can take it for a test run. LUK Maybe I am still waiting
