need advice formatting drives

[tgfyhre]

I have 2 new Toshiba 4TB hard drives, and I will be formatting them this weekend. Normally, I do the full format instead of the quick format, to check for and mark bad sectors. This is the first time I've formatted 4TB drives - the highest I've done previously is 3TB.

I'd like to format them in my 2 external 4-bay enclosures (1 new drive in each enclosure). Is there any problem with formatting both drives at the same time in different enclosures? That would save a lot of time for me.

Also, does Toshiba have drive software for disc testing, like Seagate Tools or WD Diagnostics Tool? If not, can either of those be used on the new Toshiba drives?

I use Partition Wizard free Disk Surface Test for checking disks.

Or use http://www.sevenforums.com/tutorials/433-disk-check.html

Downloads | HGST Storage Toshiba acquired by WD (at least partially), right? Or was it Hitachi? or both?

Is it even possible to format 2 discs at once using Windows disk management? I've never tried that before? I always formatted 1 disk at a time.

 

[GokAy]

No idea Let us know how it goes if you try that!

 

[tgfyhre]

Is it still a good idea to format a large 4TB drive with full format? I worry that's a lot of strain on a new drive, writing 4TB straight through like that, but then some say it's a good way to test a new drive for faults.

You do not need to treat new hardware like a newborn child. It was made to work, so work it!
If a new piece of hardware is defective and is going to fail I would rather it happen right away, not after I have been using it a while.

That said, I have stopped doing a full format on brand new drives (I still do it on used drives). I rely on surface scans and SMART reports instead. That is not the best way to test a new drive, but it is practical given how much time it takes to full format very large drives.

Good point about rather having the hard drive fail now than when it is full of important data. I don't mind letting it format overnight so I'll do that to put the drive through it's paces.

Is there a way to access any log after formatting that would show the results of the format?

 

[TVeblen]

Not with a Windows format that I know of.
You can run a hard drive diagnostic test on the drive - either Chkdsk or one from the manufacturer - and that will give you test result info.

Is there a diagnostic tool for Toshiba drives? I know Seagate has Seagate tools and WD has WD Diagnostic. Does Toshiba have their own tools or can I use WD Diagnostic on a Toshiba? How about Hitachi drive fitness - will that work on a Toshiba drive?

Hitachi Drive Fitness Test is the best one to use with Toshiba hard drives.

Hitachi Drive Fitness Test is the best one to use with Toshiba hard drives.

Thank you. Is there a Windows-based version of the software or is it only run by disc? One issue with Hitachi Drive Fitness:

Notes:

Does not support Microdrive Digital Media products.
Supports all Travelstar HDDs, except 8E, 10E and C4K series.
Does not support Endurastar products.
Does not support external USB or Firewire attached drives.
Compatible only with x86-based processors.
Does not support the PC which loads Intel ICH9M chipset.

So it won't work on my external USB 3.0 enclosure. I also read that Hitachi Drive Fitness Test won't work on 3TB or larger drives. Is that true?

 

[tgfyhre]

How about HGST Windows Drive Fitness Test? Will that work with Toshiba drives?

"WinDFT is a utility that will quickly test your HGST internal and external hard disk drives as well as all single drive G-Technology products. WinDFT will perform read tests without overwriting customer data. WinDFT also has additional utilities if you need to wipe the disk clean of data."

If I just do a full format with Windows, I'll have no idea if Windows actually found any bad sectors since it won't tell me. I'm wondering if it would make more sense to do a quick format and then run something like Seagate tools or HGST Windows Drive Fitness Test? That way I'll know if it found any bad sectors. Will either of those mark off bad sectors like a full format would do so they can't be written to? Honestly both drives I'll be testing are new, and I'd feel better exchanging them if any bad sectors are found, which is why I'd like to know the results.

I'm reasonably sure that I've read that the HGST test will work on most any brand.

However, the following is a quote from a post on this forum from a highly regarded storage oriented member:


"Western Digital Data Lifeguard Diagnostic may try to auto repair bad sectors and may make the issue worse. On the other hand Seagate Seatools will only perform a read test. To repair bad sectors, user should manually enable the repair mode. I have been using Seatools for a decade. I have tested at least 1000 disks and it never screwed a single drive.

There are two reasons I prefer Seatools over others.

1. Seatools will work with any manufacturer's disk.

2. It will abort the test to prevent further damage if there are too many surface tests.

Before testing with Seatools, make sure the disk is connected directly to a SATA port and avoid USB enclosure. If it is already connected to a SATA port, replace the data cable with a good quality 6GB/s cable. Often a faulty cable may make the disk looks like bad.

For Windows version of Seatools, the test to run is "Long generic" which will scan entire disk surface."

Thanks for this info. Will the "Long Generic" test mark bad sectors like a full format would do? Would I be wise to still run a full format if I'm going to run the long generic test, or would a quick format be fine?

And would esata be okay in an enclosure with seatools, or should I put it in my main tower and use sata?

I've never run Seatools, but I'd certainly assume so, otherwise it hasn't fixed anything and wouldn't be worthy of being called a "tool" if it can only identify bad sectors, but not retire them to the bench.

Would I be wise to still run a full format if I'm going to run the long generic test, or would a quick format be fine?

I'd think a full format would be redundant in that case and that a quick format would be fine, assuming the drive passes the tests.

And would esata be okay in an enclosure with seatools, or should I put it in my main tower and use sata?

I can't speak for Seatools, but I've certainly run Western Digital tools on drives in an external dock (not an enclosure) through eSATA. No issues. I've formatted through eSATA, restored images through eSATA, and run my PC through eSATA.

Notice in the quote from the member I referred to, regarding Seatools:

[tgfyhre]

From what I've read about Seatoools, it's recommended to run the long generic test, and as soon as it finds a bad sector, it fails the test. Then you can manually run the option to repair the disk. A full Windows format will automatically mark the bad sectors so they won't be used during the format, so when it's complete, the drive is ready to use with the bad sectors marked so they won't be used. I'm not sure what's better. When "repairing" bad sectors with Seatools, is it fixing bad sectors or is it just marking them bad like full format does? That's what I'm still confused about.

See my post 16.

That's the best I can do.

Where I come from, "repair" and "fix" are synonyms.

But I don't think bad sectors are ever actually "fixed" or "repaired". They are identified and sent out of the game, permanently, and cannot later be used for data or Windows or at all.

 

[tgfyhre]

Agreed, but Windows full format doesn't fix bad sectors to my knowledge - it marks them as bad so they can't be used. That's what I'm trying to understand. Does Seatools fix the bad sectors as in, they aren't bad anymore, or does it just mark them as bad like full format so they aren't used?

It doesn't actually explain this.

 

[ignatzatsonic]

Does Seatools fix the bad sectors as in, they aren't bad anymore, or does it just mark them as bad like full format so they aren't used?

See my previous post.

I seriously doubt that bad sectors are ever truly "fixed" or "repaired". If you raked a screwdriver across a disk platter, how could software possibly fix it?
