My disk is too small? Too small for what?

#1 Post by flyvapnet » 08 Jun 2014, 23:03

I'm running TestDisk 6.14.0.0 in an effort to fix my C disk, since CHKDSK quit working several months ago. (It won't start on re-boot.) My disk is "dirty" and until it's "fixed" neither Windows nor third-party defragmenters will operate.

Lo and behold, TestDisk tells me "The harddisk <40 GB / 37 GB> seems too small! << 80 GB / 74 Gib>"! It's not going to get any bigger, so what should I do now?

Also, TestDisk informed me:
The following partition can't be recovered:
Partition / Start / End / Size in sectors
> HPPS - NTFS / 5166 239 63 / 10333 238 62 / 78124977
What I'm wanting TestDisk to do is FIX the "dirty" disk. Perhaps I failed to properly interpret the large print (which giveth) or else I didn't see the fine print (which taketh away). In the event, isn't TestDisk supposed to fix "dirty" disks? I sure wish it would, but it doesn't seem so inclined.

Please help me, if you're able, via helpful advice. Thank you very much!

Hi there.
I don't know much about Testdisk but I do have HDD that failed to boot. My advice is turned this HDD that failed to boot as a slave drive and connect this HDD to your PC to copy all the data via USB X.0 to SATA/IDE interface. Then reformat the HDD in order to use it. The data is totally intact in your HDD unless the HDD is totally defective/ not running at all.

A message like:
The following partition can't be recovered:
has no significance, because it's only a message that testdisk can't recover it, because your partition ends probably after disk limit.
Important are the results.
Until yet, your infos are too little to judge it
Some info about the size of your disk would be important and repeat your diagnose running testdisk / Analyse / Quick and if it's possible Deeper Search also.
You can copy and paste the content of your testdisk.log into your next post.
But it's only necessary if your disk size is recognized correctly.
If not, please let me know.
Also check the size of your disk in your disk management console.

Check the harddisk size: HD jumpers settings, BIOS detection...
