Multiple Google Drive

[Landers Piechotka]

Iam interested in buying the backup 2Tb subscription for my desktop which has two hard drives in it. It says to just select the drive you want to back up. Do all the files have to be on one drive and not spread across multiple hard drives?

Thanks Nancy, it is becoming clearer. I didn't know if when Dropbox created that folder it had to reserve the space at that point in time. As I have c 1.7Tb of data it would be physically impossible to create a second folder big enough to match that on a 2Tb drive.

I assume the Dropbox folder provides the logical boundary for the data in it and when I load stuff into it the content of the Dropbox folder increases logically but doesn't increase the overall space required on the hard drive.

Yes, I got that, but most computers only have one hard drive. I have two hard drives within my desktop with different activity on them and I want to know whether Dropbox treats them as one computer or whether all the files within the computer I want to back up have to be on the same physical drive or whether I can add folders from both drives?

The normal sync process for Dropbox will only sync the items located in the Dropbox folder that gets created upon install. If you want files to sync, you need to put them in the Dropbox folder. You can't sync other locations on your computer.

Thanks Rich, I will take that as meaning a computer equals only one hard drive, even if there are two installed. In Windows I can add folders from multiple drives to the quick access menu and that would imply I could do the same with Dropbox, but it seems not. So I will have to set up my computer with one partition with 2 Tb and all I want to be backed up to be on that drive. It's a shame they don't have a proper support desk who would be able to answer these questions without relying on the goodwill of the community. Thanks

Hi Rich, Thanks for your reply. So that sounds like to backup 2Tb of data I need a folder of that size when I create it. Does that have to be empty before the files are put in, or can I designate an existing drive and include the existing folders on it? It affects whether I somehow need to create an empty folder somewhere as well as the stuff to back up, or whether I can designate the hard drive with all my data in as it is. Given it is the active W10 drive with email and everything I would rather not have to move everything off the drive I want backing up, create the Dropbox folder and then add all the folders back.

I use an ssd (C:) for my (Windows 8.1) system drive and an hdd (D:) for data, with the library folders redirected to D:. That works fine, but somehow the D: drive got an extra drive letter (E:) assigned as well, so it shows up twice in File Explorer. Both entries work, and the contents are identical, so it really is for the same physical drive. Disk Manager shows only the one drive, labelled D:, but the E: drive letter is unavailable for assignment.

I've had success in these sorts of situations with DISKPART. From a command prompt, type diskpart. Then, list volume to show the available volumes. Use select volume to select the one with D & E. Then, type remove letter=e, then exit, and close the command prompt.

USBDeview works fine for that. I had a USB using multiple drive letters (4!!!) needed for my hard drives. And if diskpart couldn't do it, this soft did it without breaking a sweat. Quiet amazing USB tool actually. Tons of infos and options in there !

I am running OS X Yosemite on my iMac (27-inch, Late 2013)... when I first set my Pegasus R4 up one of the drives began to fail almost immediately but I could still mount the drives and I managed to replace it.

The four drives have worked perfectly since until this morning (14th April 2020) when I booted up and TWO drives (1 & 4) failed. I can't mount the drives at all so I now have no access to my backup. There is a little over 12Tb of material on there which I can't get to - as you'll imagine I'd like to save some of the material there - some is vital.

OK, it looks like the drives did not go offline at a different times. But still the safest thing is to force one drive online and start a rebuild on the other drive. From the CLI again you can force PD0 online with

Be very careful with the next steps, we need to make PD4 unconfigured, and we will do this by removing all drives except PD4 and deleting the array information on PD4 only.

First, power the Pegasus down (easiest way is to disconnect the thunderbolt cable), wait 30 seconds for the drives to spin down, then unseat all the drives except PD4, reboot and verify that only PD4 is seen, then force it online and delete the array.

This won't delete your array, only the stale array data on PD4, the other (unseated) drives contain the actual array. That's why you need to verify with the 'phydrv' command that only PD4 is seen.

Once PD4 has been cleaned of array information, 'phydrv' should show it unconfigured.

Then power off the Pegasus again, give it 30 seconds or so to let the drives spin down, and reseat all the other drives and unseat PD4. Power the Pegasus back on and let it boot, verify that all the drives except PD4 are seen and that the array and LD are present and the LD is online, then reseat PD4. If PD4 is unconfigured, an automatic rebuild will start. You might want to change settings so that the MAC does not sleep or power off until the rebuild completes.

Have followed the instructions - the drive has been rebuilding now for twelve hours - I can see and access all my files on the other drives but the fourth drive is still rebuilding - does this sound about right? I have no idea how long it might take to rebuild...

Dear Martin GodlemanThank you for contacting Promise Technical Support.There is a response to your tech support case # 20200414070545SCurrent Response : Hi Martin, Yes the drives are marked as dead due to removal, they do not have any errors, let us know once the rebuild is complete. Regards, GauthamTo view details, please go to and login.Thank you!

Everything posted above deals Martin Godleman's Pegasus and the state it was in. The instructions given do not apply to any other Pegasus and applying them to a Pegasus with a different issue may cause harm.

Like the first poster here, I've just experienced multiple drive failures on my Pegasus R4 which I've got hooked into my Late-2012 iMac. I've had the Pegasus R4 since at least 2013 and it's been reliable in all that time until now. Recently I updated both the firmware and the utility software to the latest versions after I had one of the drives fail suddenly a few weeks ago. I replaced the drive with a Seagate 1 TB 7200 rpm (all my drives in the unit are 1 TB for a total of 3 TB when the array is fully functional) and rebuilt my array back to full function, but then the brand-new drive failed (the aforementioned Seagate) after a few days, so I replaced with a spare blank Seagate 1 TB I had just in case. I restored my array back to full function again and this time the array only lasted a single day before the new drive failed too. The utility software tells me that both new drives were 'dead' drives, despite the fact that they were fresh and new right from Best Buy. Either Best Buy is seling a bad batch of Seagates all of a sudden or my Promise Pegasus R4 is suddenly eating hard drives for lunch.

Before this happened, since I was already feeling that something was iffy with Seagates, I ordered more drives from the online store and got a pair of Western Digital drives this time to keep as spares. And then just as they arrived in the mail, the latest new Seagate drive I installed in the Pegasus suddenly failed, and then to put insult to injury, another drive in my Pegasus R4 failed minutes later, one that had been working reliably for a year in a different drive slot after I had to replace a failed drive back then. This other failed drive is also a Seagate, interestingly enough. Whether the Seagates are the problem or the Promise Pegasus R4, I still don't know. But because two drives suddenly failed at once, the array itself shut down and I can no longer do a restore of my RAID-5 array at all now. I've since taken out the bad drives and put in those fresh Western Digital models, but does this mean I can no longer restore my array's files at all? It's all gone? Or is there a trick to restoration?
