I completely agree..this is true for all media... even hard drives have extra blocks that are not used and are reserved..

same for CD media (remember overburning? it wasn't magic..it was using your reserved space to burn more data)

For you to measure wear you need to measure first when you got the device and x time later as bad blocks can vary in the manufacturing process...
[Epic 4G General] kenvan19:
It's also important to know that 15 blocks is not bad our even close to bad.

[Epic 4G General] Akagami:
I have flashed about 20ish times I would guess. Running RFS and have 7 bad blocks.
[Epic 4G General] DRockstar:
H2g2 & kenvan19, your math makes sense... with the following math it's obvious you're right:

512×1,024×1,024÷4,096

=131,072

131,072×0.02

=2,621.44

Hey, I overreacted then...

Further math shows that at the rate of 15 bad blocks every 3 months, it would take 43 years to run into trouble :)

Whether we have a decent set of statistics or not still remains to be seen.

For me, what this thread does is give me a starting point. I can come back after 2 more weeks of running on EXT4 and see how many bad blocks I have, how many ROMs I've flashed between now and then, etc. It's a starting point for me. Then I can odin back to stock and do the same thing.. see how many bad blocks I have, how many ROM flashes within a couple weeks etc. and compare my results to my original results.

This will help me assess whether there is any noticeable change in my device..

I understand that a couple weeks or a month may not be a decent enough time with which to compare results, but this thread gives us a starting point.

Thanks for the shout out, but your math is very wrong. The minimum WRITE size is 4k...the minimum ERASE size is 128k, which is the block size. 512MB/128KB = 4096 blocks (thats why they are using the bottom blocks in the 4000 range for the 2% coverage. 2% of 4096 is apx 81 bad blocks. But don't worry. You would have to get about 3 bad blocks per month for 2 years straight before a failure.

oh ****, you must not have a flash device on your phone ;)
[Epic 4G General] DiGi760:
Since it maps the corrected block from 4090 and goes down from there, I wonder what the lowest number reserve block is. If we knew that, we would know for sure how many bad blocks is excessive. Plapczyn says that should be approximately 81 blocks, which would count down to 4009 or so. I added together the number blocks (units) shown in bmlinfo, and it comes out to 4012. My hypothesis is that 4013 is the last reserve block available for addressing. That would give us 78 bad blocks to work with which is actually closer to the 3 blocks a month estimate than 81.

Ah, thanks for the clarification. I completely spaced out there.

This is my 3rd Epic, had it for about 3, or 4 months. Flashed EVERY rom out there atleast 20 times each. Used Odin way over 50 times... Is this bad? And, can these be fixed?

[Epic 4G General] phdeez:
I have 17 bad blocks and I have only had my phone 2 months! Bad units start @ 282 and end @ 3510!

I've only rooted my phone and never even flashed a ROM on it!

Damn, this is worrysome!
[Epic 4G General] DiGi760:
Was that a new phone or a refurb? If you dial ##786#, select view, and scroll to the bottom, does the activation date match when you got the phone?
[Epic 4G General] phdeez:
Activated 11/13/2010. That's when I purchased it. Also, it says "No" for Reconditioned. I purchased it from Best Buy... not a Sprint store.
[Epic 4G General] h2g2:
You only need to worry if you had fewer than 17 bad blocks when the phone was new. It's entirely possible your phone had 17 bad blocks from the get go. The issue isn't how many bad blocks you have, it's about the rate at which they are increasing over time. Check your phone again in 2 months and see how many more blocks you have. If the number has increased, then you can extrapolate how long it'll take for you to run out of spare blocks and exceed the 2% threshold. Chances are, you'll still have 17 and you have nothing to worry about.

IIRC, I have odined maybe no more than 10 times and flashed no more than 20-25 times. I got this unit about mid October 2010. Currently running Bonsai 1.1.3, EXT4, with no journaling mode active.
[Epic 4G General] Randy_T:
Running Ext4 since the day it became available. Reflash roms nearly daily lately. Have run Ext4 reformat-nojournal mod several times as well.

Checked my bad-block count again, 8 days later, and it looks identical to my original post above... no additional bad blocks while on EXT4 thus far.
[Epic 4G General] GucciPilot:
So I got an epic the day it came out and swapped it out a week later for a bad capacitive button. I odin flashed the phone 3 times, one to custom rom, one back to stock and then dk28 stock rom. Rooted using the all in one root and recovery tool. I copied the command from the Original Post into connectbot and attached a screen shot 12 Bad Blocks, always been on RFS.
