Help ! OS3.9 HDD Sector trubbs

[Agafaster]

I recently got round to copying all the games installed on me old (2 .5" 810MB) Hard Disk onto me new (3.5" 19GB) One. All the stuff went into a drawer in my APPS: partition to be placed on a new GAMES: partition. right.
got as far as successfully generating a 2GB partition out of the 14GB of unallocated disk,
and formatted this (GOD that was slow ! I only have an IDEfix'97 board - 2.2MB/s is a tad slow for that capacity !).
I put an Icon there for the new volume, and copied the games over.
came to reboot later, and got "Read Error on block <>" and lost all me stuff !
(incidentally I assumed crap sector, and repartioned a 1GB lump - reformatted, bing ! same error, different block . D'oh !)
Now I would have normally reached straight for DiskSalv, but since this disk is > 4 GB, that wont work -

what do I do ? I want to either re-route around the duff block so the disk validates properly upon boot, or I want to have some software fix the (hopefully) soft error on that block.
Is there an NSD version of Disksalv ?

I am using WB3.9 BB2 on an A1200T with IDEfix'97 board. the disk is on IDE port 0, shared with a 54x CDROM - the setup has been fine 'til now.

I dont wanna have to start the disk from scratch !

Never ever use regular format, ALWAYS use Quick:

a) normal format is never needed, unless if you suspect HW defect on the harddisk.
b) quickformat is seconds compared to hours with normal format
c) some format versions trash RDB/first partitions when they access >4gig area, when using normalformat. Quickformat is safe.

If you really need a working normalformat for >4gig area, get the format tool from aminet. Can't remember the name atm, someone refresh my memory...

ok...youre sure about this ? even for freshly partitioned lumps of unpartitioned disk space ?

aha !! absolutely does !

it IS the format that comes with OS3.9 for NSD's isnt it ?

ta, I'll have a look.

PS - you forgot to mention Vodka, 3 month long days/nights and excellent Black Metal !!  :-D

yes. yes.

Even brand new hard disks are ready to use without any formatting.

No idea. I only had OS 3.5. OS 3.5 format is not.

To be on the safe side, always use quickformat.

Cheers me mon !

I'll give it a whirl (pun intended !) tonight and let you know in the morning.

Worth repartitioning before I use the QF ? in case the Nomal one has fsck'ed anything ?

:pint: :hammer: :-D

Remember to use the correct default settings also in HDTOOLBOX, as OS3.9 gives the correct size of the disk.

So for example if your drive is 74.3GB in size but  HDToolBox shows it as 68.3GB, AmigaDOS measures in numbers that are meaningful to file system, powers of two. A GiB,the proper ISO term, is 1024*1024*1024. If you multiply that by the 68.3 you get your 73,336 million bytes.

Also check your mask settings.

erol,

yes absolutely.

odd that the standard for kilo is 1024 in computer terms, yet the drive mfrs insist on advertising using 1000 ! (actually, I think a manufacturers GB* is 1000*1024*1024 making a 20GB Maxtor actually 19.5GB)

*hmmm - baker's dozen, anybody ? ;-)

I fully understand. I wouldnt have asked if me disk was < 4GB ! (I'd've used Dave Haynie's DiskSalv)

consider moving to PFS3, its a fantastic product.
I don't know what SFS is like but i wont change as i've never had issues with PFS3.

[Hardboy]

Smart file system is really worth it. It´s also free and can obtained on aminet..

I use SFS on my partitions and it really makes a difference...

Even though you have an IDEFix97 board, you should still consider setting the MaxTransfer value for each partition to 0x1fe00.
