A Failing Toshiba External Drive, Ten Years of Photos and Tax Records, and Getting Them Off in Time
A Toshiba 1 TB external drive that kept appearing and disappearing held a decade of photos, scanned documents and tax records. The drive was failing but still readable, so the data was copied off with a tool built for dying drives, which keeps going past bad spots instead of stopping, onto a new exFAT drive that reads on Windows and Mac. Retire the old drive, keep two copies in two places, and make the backup automatic.
The customer brought me a Toshiba 1 TB external hard drive and a worry. The drive held years of important files, and it had started acting up. Some days the computer saw it. Some days it did not. They wanted everything pulled off before it stopped showing up at all.
That instinct was exactly right, and the timing was good. A drive that is intermittent is a drive that is still giving you a chance.
What I found
The Toshiba was failing. It was hit or miss to even detect: it would mount, drop off the computer, and need to be reconnected to come back. That pattern, a drive that appears and disappears, is one of the classic early signs of a mechanical drive on its way out. It was formatted in the older FAT32 format and held roughly half a terabyte, a personal archive going back more than a decade. Family photos. Scanned documents. PDFs. Tax records.
In short, exactly the data you cannot replace, on a drive you cannot trust.
Why the copy method matters more than the software
Most people's first move with a dying drive is to open it in Explorer and drag the folders across. That is the wrong move, for two reasons. Every minute the drive spins is wear on a mechanism that is already failing, and a normal copy stops dead at the first unreadable spot. One bad sector in a folder of ten thousand photos and the whole job halts, and now you have spun the drive for an hour for nothing.
So I did it the other way around.
- Handled the drive gently and kept it powered only as long as the job needed. Every extra spin-up on a dying drive is a risk, so it stayed unplugged until the destination was ready.
- Used a copy tool built for failing drives. It reads everything it can, notes any bad spots, keeps going instead of stopping, and comes back for the difficult areas last. That way the good ninety-nine percent is safe before the drive is asked to struggle over the rest.
- Moved it all onto a new 1 TB external drive, formatted in exFAT so it reads on both Windows and Mac with no extra software and no file-size limits, which FAT32 has.
- Kept the original folder structure intact, so everything is where the customer expects it to be.
The result
The archive came across, photos and tax records included, and now lives on a new, reliable drive that opens on any modern computer. The Toshiba's job is done. The whole thing fit inside my standard pricing, which is on the pricing page.
What I told the customer, and what I will tell you
- Retire the old drive. It is failing. It should not be trusted with anything important again, and it should never be the backup. A drive that has started dropping off does not get better.
- Do not keep only one copy. This is the one that matters. After a recovery, the data is on a single drive again, which is one failure away from the same emergency. The rule is two copies in two places: keep the new drive, and put a second copy somewhere else, a second drive or a cloud backup for the irreplaceable things like the photos. I wrote up how to think about that in backup basics.
- Make it automatic. A backup you have to remember is a backup that does not happen. Setting one up so it runs on its own is a short visit, and it is the difference between this being a story you tell and a story you live through again.
If your drive is doing this right now
Unplug it and stop trying it. Do not run a repair utility on it, do not reformat it when Windows offers to, and do not keep reconnecting it to see if it works this time. Each attempt spends some of what is left. The drive is telling you it has a little time. Use that time to get the data off properly, and then never depend on one drive again.
Questions people ask
My external hard drive keeps disconnecting and reconnecting. Is it dying?
Very likely. A drive that appears, drops off, and needs to be unplugged to come back is showing a classic early failure sign. Stop using it and get the data copied off while it still reads.
Can I just drag my files to a new drive myself?
You can try, but a normal copy stops at the first unreadable spot and every minute of spinning wears the drive further. A copy tool built for failing drives captures everything readable first and returns to the bad areas last.
What format should the new external drive be?
exFAT. It opens on both Windows and Mac without extra software and has no file-size limit, unlike the older FAT32 format many drives ship with.
Once my files are recovered, am I safe?
Not yet. They are on one drive again. Keep two copies in two places, such as the new drive plus a cloud backup for the irreplaceable items, and set the backup to run automatically.
