My grandchildren are the biggest users of games on my iPad. They
tell me that quite often they will start a game and then it will fail
before they get going. For the most part, they can start again and
continue. Occasionally, they will have to restart more than once.

One game they wanted to try, "Dragons Rage", seems to load a bit more
each time they try, but never got all of the way loaded.

I wonder if there's some kind of Check disk I should use, or whether I
should note which apps these are and then delete and undelete them
from the iPad, or any other kind of maintenance.

You've raised a big question here. Disk fragmentation, index integrity.
How do we check, change or repair these?

On my TV DVD-recorder there's an option for clearing the hard drive.
Is there anything to validate or tidy the iPad one?

no he hasn't. those apps are buggy. well written apps do not crash on
launch.

fragmentation is certainly not a problem and fsck is part of os x.
those who jailbreak can see it run in the console log that's dumped to
the screen.

reboot the ipad, but there's rarely a need.

There is no hard drive on iPads.....

Also you don't want to defrag flash memory. It is not necessary as
there are no moving parts and it will used up it"s read/write cycles.

there's also rarely a need to defrag hard drives with modern operating
systems.

No, but periodically I run the Disk Utility on my Mac, and often it
does find problems.

fsck might have some value, but defragmentation is almost useless when
the "drive" is flash memory.

There will be some overhead in reassembling a lot of small fragments
into one block, but it will be miniscule compared to the main benefit of
defrag, which is to minimize time wasted moving the read/write head all
over the place.

Many flash products nowadays have firmware that causes fragmentation, in
order to reduce "wear-out" by giving all sections of the memory equal
usage. Running defrag on those will accomplish nothing other
then waste write cycles.

Then if I were you, I'd start worrying about a disk failure.

for flash, it's worse than useless. it's a really bad idea for the
reasons you cite, wear-leveling and the access time for flash is the
same regardless of where the data actually is so it doesn't matter if
files are fragmented or not.

for hard drives, defragmenting is rarely needed except in specific
circumstances such as video capture. it can also make things worse in
some cases because defragmenting can affect hot clustered files which
are put in a specific location on the hard drive for quick access.

There is no hard drive in an iPad. And nothing like check disk for it
either that I'm aware of.
